The Mount Elliott Mining Complex is an aggregation of the remnants of copper mining and smelting operations from the early 20th century and the associated former mining township of Selwyn. The earliest copper mining at Mount Elliott was in 1906 with smelting operations commencing shortly after. Significant upgrades to the mining and smelting operations occurred under the management of W.R. Corbould during 1909 - 1910. Following these upgrades and increases in production, the Selwyn Township grew quickly and had 1500 residents by 1918. The Mount Elliott Company took over other companies on the Cloncurry field in the 1920s, including the Mount Cuthbert and Kuridala smelters. Mount Elliott operations were taken over by Mount Isa Mines in 1943 to ensure the supply of copper during World War Two. The Mount Elliott Company was eventually liquidated in 1953.
The Mount Elliott Smelter:
The existence of copper in the Leichhardt River area of north western Queensland had been known since Ernest Henry discovered the Great Australia Mine in 1867 at Cloncurry. In 1899 James Elliott discovered copper on the conical hill that became Mount Elliott, but having no capital to develop the mine, he sold an interest to James Morphett, a pastoralist of Fort Constantine station near Cloncurry. Morphett, being drought stricken, in turn sold out to John Moffat of Irvinebank, the most successful mining promoter in Queensland at the time.
Plentiful capital and cheap transport were prerequisites for developing the Cloncurry field, which had stagnated for forty years. Without capital it was impossible to explore and prove ore-bodies; without proof of large reserves of wealth it was futile to build a railway; and without a railway it was hazardous to invest capital in finding large reserves of ore. The mining investor or the railway builder had to break the impasse.
In 1906 - 1907 copper averaged £87 a ton on the London market, the highest price for thirty years, and the Cloncurry field grew. The railway was extended west of Richmond in 1905 - 1906 by the Government and mines were floated on the Melbourne Stock Exchange. At Mount Elliott a prospecting shaft had been sunk and on the 1st of August 1906 a Cornish boiler and winding plant were installed on the site.
Mount Elliott Limited was floated in Melbourne on the 13th of July 1906. In 1907 it was taken over by British and French interests and restructured. Combining with its competitor, Hampden Cloncurry Copper Mines Limited, Mount Elliott formed a special company to finance and construct the railway from Cloncurry to Malbon, Kuridala (then Friezeland) and Mount Elliott (later Selwyn). This new company then entered into an agreement with the Queensland Railways Department in July 1908.
The railway, which was known as the 'Syndicate Railway', aroused opposition in 1908 from the trade unions and Labor movement generally, who contended that railways should be State-owned. However, the Hampden-Mount Elliott Railway Bill was passed by the Queensland Parliament and assented to on the 21st of April 1908; construction finished in December 1910. The railway terminated at the Mount Elliott smelter.
By 1907 the main underlie shaft had been sunk and construction of the smelters was underway using a second-hand water-jacket blast furnace and converters. At this time, W.H. Corbould was appointed general manager of Mount Elliott Limited.
The second-hand blast furnace and converters were commissioned or 'blown in' in May 1909, but were problematic causing hold-ups. Corbould referred to the equipment in use as being the 'worst collection of worn-out junk he had ever come across'. Corbould soon convinced his directors to scrap the plant and let him design new works.
Corbould was a metallurgist and geologist as well as mine/smelter manager. He foresaw a need to obtain control and thereby ensure a reliable supply of ore from a cross-section of mines in the region. He also saw a need to implement an effective strategy to manage the economies of smelting low-grade ore. Smelting operations in the region were made difficult by the technical and economic problems posed by the deterioration in the grade of ore. Corbould resolved the issue by a process of blending ores with different chemical properties, increasing the throughput capacity of the smelter and by championing the unification of smelting operations in the region. In 1912, Corbould acquired Hampden Consols Mine at Kuridala for Mount Elliott Limited, followed with the purchases of other small mines in the district.
Walkers Limited of Maryborough was commissioned to manufacture a new 200 ton water jacket furnace for the smelters. An air compressor and blower for the smelters were constructed in the powerhouse and an electric motor and dynamo provided power for the crane and lighting for the smelter and mine.
The new smelter was blown in September 1910, a month after the first train arrived, and it ran well, producing 2040 tons of blister copper by the end of the year. The new smelting plant made it possible to cope with low-grade sulphide ores at Mount Elliott. The use of 1000 tons of low-grade sulphide ores bought from the Hampden Consols Mine in 1911 made it clear that if a supply of higher sulphur ore could be obtained and blended, performance, and economy would improve. Accordingly, the company bought a number of smaller mines in the district in 1912.
Corbould mined with cut and fill stoping but a young Mines Inspector condemned the system, ordered it dismantled and replaced with square set timbering. In 1911, after gradual movement in stopes on the No. 3 level, the smelter was closed for two months. Nevertheless, 5447 tons of blister copper was produced in 1911, rising to 6690 tons in 1912 - the company's best year. Many of the surviving structures at the site were built at this time.
Troubles for Mount Elliott started in 1913. In February, a fire at the Consols Mine closed it for months. In June, a thirteen week strike closed the whole operation, severely depleting the workforce. The year 1913 was also bad for industrial accidents in the area, possibly due to inexperienced people replacing the strikers. Nevertheless, the company paid generous dividends that year.
At the end of 1914 smelting ceased for more than a year due to shortage of ore. Although 3200 tons of blister copper was produced in 1913, production fell to 1840 tons in 1914 and the workforce dwindled to only 40 men. For the second half of 1915 and early 1916 the smelter treated ore railed south from Mount Cuthbert. At the end of July 1916 the smelting plant at Selwyn was dismantled except for the flue chambers and stacks. A new furnace with a capacity of 500 tons per day was built, a large amount of second-hand equipment was obtained and the converters were increased in size.
After the enlarged furnace was commissioned in June 1917, continuing industrial unrest retarded production which amounted to only 1000 tons of copper that year. The point of contention was the efficiency of the new smelter which processed twice as much ore while employing fewer men. The company decided to close down the smelter in October and reduce the size of the furnace, the largest in Australia, from 6.5m to 5.5m. In the meantime the price of copper had almost doubled from 1916 due to wartime consumption of munitions.
The new furnace commenced on the 16th of January 1918 and 77,482 tons of ore were smelted yielding 3580 tons of blister copper which were sent to the Bowen refinery before export to Britain. Local coal and coke supply was a problem and materials were being sourced from the distant Bowen Colliery. The smelter had a good run for almost a year except for a strike in July and another in December, which caused Corbould to close down the plant until New Year. In 1919, following relaxation of wartime controls by the British Metal Corporation, the copper price plunged from about £110 per ton at the start of the year to £75 per ton in April, dashing the company's optimism regarding treatment of low grade ores. The smelter finally closed after two months operation and most employees were laid off.
For much of the period 1919 to 1922, Corbould was in England trying to raise capital to reorganise the company's operations but he failed and resigned from the company in 1922. The Mount Elliott Company took over the assets of the other companies on the Cloncurry field in the 1920s - Mount Cuthbert in 1925 and Kuridala in 1926. Mount Isa Mines bought the Mount Elliott plant and machinery, including the three smelters, in 1943 for £2,300, enabling them to start copper production in the middle of the Second World War. The Mount Elliott Company was finally liquidated in 1953.
In 1950 A.E. Powell took up the Mount Elliott Reward Claim at Selwyn and worked close to the old smelter buildings. An open cut mine commenced at Starra, south of Mount Elliott and Selwyn, in 1988 and is Australia's third largest copper producer producing copper-gold concentrates from flotation and gold bullion from carbon-in-leach processing.
Profitable copper-gold ore bodies were recently proved at depth beneath the Mount Elliott smelter and old underground workings by Cyprus Gold Australia Pty Ltd. These deposits were subsequently acquired by Arimco Mining Pty Ltd for underground development which commenced in July 1993. A decline tunnel portal, ore and overburden dumps now occupy a large area of the Maggie Creek valley south-west of the smelter which was formerly the site of early miner's camps.
The Old Selwyn Township:
In 1907, the first hotel, run by H. Williams, was opened at the site. The township was surveyed later, around 1910, by the Mines Department. The town was to be situated north of the mine and smelter operations adjacent the railway, about 1.5km distant. It took its name from the nearby Selwyn Ranges which were named, during Burke's expedition, after the Victorian Government Geologist, A.R. Selwyn. The town has also been known by the name of Mount Elliott, after the nearby mines and smelter.
Many of the residents either worked at the Mount Elliott Mine and Smelter or worked in the service industries which grew around the mining and smelting operations. Little documentation exists about the everyday life of the town's residents. Surrounding sheep and cattle stations, however, meant that meat was available cheaply and vegetables grown in the area were delivered to the township by horse and cart. Imported commodities were, however, expensive.
By 1910 the town had four hotels. There was also an aerated water manufacturer, three stores, four fruiterers, a butcher, baker, saddler, garage, police, hospital, banks, post office (officially from 1906 to 1928, then unofficially until 1975) and a railway station. There was even an orchestra of ten players in 1912. The population of Selwyn rose from 1000 in 1911 to 1500 in 1918, before gradually declining.

Mud-puddling is the phenomenon mostly seen in butterflies and involves their aggregation on wet soil, dung and carrion to obtain nutrients such as sodium and amino acids. This behaviour is restricted to males in many species and in some species the presence of butterflies on the ground acts as a stimulus for their aggregation.
In tropical India this phenomenon is mostly seen in the post-monsoon season. The groups can include several species including members of the Papilionidae and Pieridae.

..."puddling".
"Puddling" is behavior most conspicuous in butterflies, but occurs in other animals as well, mainly insects; they seek out certain moist substances such as rotting plant matter, mud and carrion and they suck up the fluid. Where the conditions are suitable conspicuous insects such as butterflies commonly form aggregations on wet soil, dung or carrion. From the fluids they obtain nutrients such as salts and amino acids that play various roles in their physiology, ethology and ecology.
Lepidoptera (butterflies and moths) are diverse in their strategies to gather liquid nutrients. Typically, puddling behavior takes place on wet soil. But even sweat on human skin may be attractive to butterflies such as the Hackberry Emperor. More unusual sources include blood and tears. Again, similar behavior is not limited to the Lepidoptera, and for example, the various species of bees commonly called sweat bees are attracted to various kinds of sweat and tears, including that of humans.
In many species puddling behavior is restricted to males, and the presence of an assembly of butterflies on the ground acts on the Pipevine Swallowtail for example, as a stimulus to join the presumptive puddling flock. Males seem to benefit from the sodium uptake through puddling behavior with an increase in reproductive success. The collected sodium and amino acids are often transferred to the female with the spermatophore during mating as a nuptial gift. This nutrition also enhances the survival rate of the eggs.

The Vernon Tigers were a Minor League Baseball team that represented Vernon, California in the Pacific Coast League from 1909 to 1925. The team won back-to-back PCL pennants in 1919 and 1920. The Tigers, together with the Sacramento Solons, joined the PCL as a new team in 1909 when the league expanded from four teams to six. The Tigers effectively were a second team in Los Angeles, rivals of the existing Los Angeles Angels.

(Los Angeles Herald, 16 May 1909) - Manager Benkert of the Maiers has signed Myers, the crack southpaw of the Long Beach team, to take the place of John Raleigh, who goes to Blsbee, Arizona.
(Los Angeles Herald, 13 June 1909) - Raleigh Handles Himself Well in Two Innings, in Which He Replaces Harkins Against the Angels - He was the medium of the introduction of a young bush wirier who bears all the marks of real class and may prove to be a find. This man is John Raleigh, formerly a pitcher on the Maiers team, amateur aggregation of Los Angeles. Hogan brought in the tall rangy, cool-headed youngster. So many unknowns have been used by Hogan that it was at first impossible to gather his name, but Umpire Toman finally vouchsafed the information that the young man had borne through his life's troubles the surname of a courtier of great renown. Now Raleigh may not know what a courtier is and perhaps he never heard of the Elizabethan hero, and he might be much perturbed in royalty's presence, but he knows how to handle himself in a ball game, as the Angels discovered before an inning had passed. Never has a cooler and more level-headed busher laced a collection of champions. He struck out two men and allowed one hit in the two innings in which he starred for Hogan's crew, and after the first few moments of guesting as to how much havoc the Angel hitters would do to his reputation the crowd sat up and took notice that here was a real performer. He made a hit by his steadiness in his first appearance and Hap Hogan probably will use him more than once hereafter.
(Los Angeles Herald, 25 June 1909) - RALEIGH MAKES SHUT-OUT DEBUT - HOGAN'S NEW PITCHER PROVES FIND OF THE SEASON - BUSHER ADMINISTERS SEVERE LACING TO OAKS - Nomination of Former Amateur for Box Duty Proves Justifiable When Youngster Twirls Big League Ball - This is about the whole story of the 8 to 0 victory over the tall-enders yesterday. John Raleigh is the lion of the hour among the populace of Vernon, incidentally, and perhaps quite as important to him, he has more than made good in the Coast league and has been permanently placed on the payroll of the Vernonites, with big chances of being used as often as it la safe to work a pitcher. It was Raleigh day at the Chutes field. Every time the curly-haired wonder struck a northerner, which happened four times during the afternoon, the crowd cheered. Every time he came to bat the hand-clap was in evidence, and when he made an assist he was warmly applauded. The ex-amateur, busher, "kid," as the visitors at first contemptously termed him, played a rattling game, made the Oaklanders chop at the ball like rank bushers, held the bases empty through the greater part of the contest and capped it all by handing over to his leader a clean shut out.
(Los Angeles Herald, 9 July 1909) - RALEIGH SHUTS OUT OREGONIANS - PORTLAND IS DOWNED BY CLEVER SOUTHPAW HOGANITES PLAY FAST BALL TO RETRIEVE SHOWING - Vernon 2, Portland 0 - For the second time this season John Raleigh, who has proved himself made of that metal which does not tarnish, brought the Suburbanites through to a victory, and for a second time he handed over to his chieftain, Happy Hogan, a shutout against the men whom he attacked. These two games, and a third which he lost through poor support, are his only nine innings' appearance, but he has been on the team only a few weeks, and this is a rather high class record for a "busher" boy.
(Los Angeles Herald, 27 July 1909) - JOHN RALEIGH IS SOLD TO ST. LOUIS NATIONALS - As forecasted yesterday in "The Herald", Pitcher John Raleigh of the Vernon team was yesterday sold to the St. Louis Nationals for a sum not stated, but which Is believed to be in the neighborhood of $3000. The sale is made on the terms of immediate delivery, and Raleigh will start tonight for St. Louis and will join the twirling staff of the Nationals at once. This is a big boost for the lad who three months ago was an unknown playing in the coast amateur ranks, in what is known as the Maiera team. He was unheard of outside a small group in Los Angeles, and consequently his rapid rise is one of the most startling in the history of western baseball. The jump from the amateurs to a National league team is a big step, but Raleigh goes east with the backing of thousands of fans who believe that after he is broken into the big company he will prove a find. The action was taken by the management of the Vernon club in the face of the protests of the fandom of the Angel city, with the knowledge that the team is being deprived of valuable material, but business reasons were paramount, and Brooks and Hogan permitted tho sale to go through.
(Los Angeles Herald, 29 July 1909) - PROBABLY nowhere in the world is amateur baseball so fostered and cultivated as in Southern California. Probably no teams have the opportunity to draw on youngsters of great promise that Is afforded the Coast leaguers. An instance so startling as to be of national notice is given In the rapid rise of Pitcher John Raleigh, who left yesterday for St. Louis, there to join the St. Louis Nationals, after about six weeks' experience, in professional ball. Raleigh is a wonder. It is admitted that his ascent has been unusually rapid, and he had proved unusually proficient. But there are others where he came from. In less than two months this twirler, a young, modest and hard-working baseball player, has jumped from obscurity to national prominence, He has battled his way to the front by persistent effort, and of course the ability is back of it all. Raleigh, unlike most of the young phenoms, has made no record as a remarkable winner. He has pitched truly marvelous ball, considering his age and experience, but with it all has won few games. But he has been working consistently. At first he was nervous, but his second game, a shutout victory, cured him of professional stage fright, and right now there is not a cooler and more heady player in the west. But as before remarked, while a great career seems before the former amateur, there are others in the same field. The all-the-year-round baseball climate in Southern California affords excellent opportunity for the youngsters to develop. Among the amateur and professional teams now playing in the smaller leagues in Los Angeles are many men who are perhaps almost as good as Raleigh, and need only the chance to uncover the speed under a wise and skilled leader. The southland Is the greatest field for youngsters in the country, and there should be others to follow Raleigh's steps.
(Los Angeles Herald, 6 September 1909) - From the drowsy city of brotherly love comes first hand word of one of "ours." John Raleigh, late of the Vernon pitching staff, now a leading light on the twirling staff of the St. Louis Nationals, writes to his former leader, Happy Hogan, a breezy little letter telling of his fortunes with Roger Bresnahan and the Cardinals. It follows: "Dear friend Happy—l have been Intending to write for some time, but haven't seemed to have much good to say for myself. I don't know whether I ought to call you my friend, for I don't think any friend of mine would send me to such a place as St. Louis. I thought I knew what hot weather was down In Mexico, but the three weeks ln St. Louis certainly got my goat. I lost twelve pounds, and you know that to take twelve pounds off me is like taking feathers off a humming bird. It wouldn't be so bad if there were cool nights, but—oh. what's the use of talking about it? "I have had a little hard luck in two of my games. I held New York to three hits and two runs in eight innings. They scored on both their runs on men I walked. They sure get them around up here. I held Pittsburg to two hits, one a scratch hit made by Clarke in the ninth with one man out and a man on second. He took one of those healthy swings and bunted down the third base line, beating it out and moving the man at second up to third. Wagner hit a long fly to Rube and the runner scored. The other two games I was batter out of the box. lasting three Innings in one and two ln the other. I finished the last six innings today against Philip and shut them out. They had six hits when I went in. The only difference up here is that you must have control, that is, almost perfect control, and that is what I have to get. This is sure a nice bunch of fellows to play with. There are four pitchers on the team besides myself who have never had a year in league ball—Harmon, Bachman, Sullivan and Melter. Roger Bresnahan is a mighty nice man to work for. I have gotten along fine with him, and he certainly tries to help his men along. Jack Bliss is sure for California. He and Rube Ellis get into all kinds of arguments with the rest of the bunch by sticking up for it. Jack asked me ail kinds of questions about you and Kitty Brashear and Truck Eagan. So has everyone else from, there that I have met. Rube Ellis has had quite a slump in hitting, but is picking up again. He sure has a great arm. Just a closing word now. There Is one thing certain, that I will be back in Los Angeles this, winter, and Rube will be a close second. With regards to all, sincerely, JOHN RALEIGH."
(Los Angeles Herald, July 22, 1910) - John Raleigh formerly of Vernon, sold to St. Louis for $2500 and recently resold to Hogan for $750 was also present holding down a seat on the Villagers' bench. Raleigh will be on the mound in the near future.
(Los Angeles Herald, 26 May 1911) - OAKS LUCKY TO ESCAPE WHITEWASH BY VERNON - Raleigh Allows Four Hits and One Run and Villagers Win Game - Those pesky Villagers went over to the Oaks’ own stamping grounds at Freeman's park and smeared in a 4 to 1 defeat today. Sir John Haleigh, one of the numerous left-handers who are supposed to be custodians of the Oaklanders’ nanny, was trotted out by Happy Hogan and held the transbay boys practically helpless. Only four bingles, a homer, two doubles and a single, were made off his delivery, and, with the heavy hitting at his back, Sir John got through the fray with colors flying.

Johnny Raleigh, pitcher of the Vernon ball team, today married Miss Ethel Davis, of this city. The players have known for some time that Raleigh was thinking of married life. What proved to them that he was married was the receipt today at the Vernon clubhouse of a box of cigars with the compliments of Mr. and Mrs. John Raleigh. Hogan said that ha did not know where or by whom Raleigh had been married.
(San Francisco Call, 24 December 1913) - Pitcher John Raleigh, one of the oldest members of the Venice club, has been sold to the Vancouver club of the Northwestern league. Raleigh's work with the Tigers hardly came up to the standard last season. At times he pitched gilt edge ball, but he is a frail fellow and he must not be worked more than once a week. When Raleigh started off with Venice some years ago he looked like a star. He was given a chance in the big brush, going to the St. Louis Nationals. The weather was too warm for him in the east and he could not stand the strain. He was then turned back to Venice, where he pitched good ball for several seasons.
(Los Angeles Herald, 31 December 1913) - RALEIGH ONE PITCHER NOT AFRAID OF WORK - SAYINGS OF JOHN RALEIGH - Never play ball in one town for five years. A change in baseball every three years is practically a necessity. Pitch every game to win. If you find you cannot win in one town or a certain kind of climate, ask to be transferred. Don’t sign your contract until you are satisfied, and after you sign it, work just as hard and as often as you can. John Raleigh, for five years a wearer of the striped Venice uniform, not only is willing to go to the Vancouver club in the Northwestern league, but he is anxious to work there. Raleigh recently was turned over to the Vancouver team by “Happy'’ Hogan, leader of the Tigers. As a rule, a player does not care to go to a league of lower classification, but this is not true in Raleigh's case. “I asked Hogan to send me to the Vancouver club last year." said Raleigh today. He was not using me much and I would rather be working. "I believe I will do good work in Vancouver, as I always can pitch better ball in good weather. San Francisco is my favorite town in the Coast League, and if I was on the Seals I believe I could have bettered the averages I made while with Venice.“ Many persons believe I cannot pitch more than once a week and deliver a good brand of baseball. This is not true, for I have the stamina to take my regular turn in the box. I keep in good shape and although I am as heavy as some of the other heavers, my condition carries me through the games. "Frequent work is necessary for a twirler, and I figure I will get enough of it in the Northwestern league, and that the climate will suit me. I have been with the Tigers five years, and that is too long for a player to remain with one ball club, They should change every three years.”
(Los Angeles Herald, 12 February 1914) - John Raleigh is Through Playing League Baseball - John Raleigh, former Venice pitcher who was sold to Vancouver, has jumped organized baseball. He will not join the Federals, but will pitch for the Bingham mine team near Salt Lake City. Raleigh was offered a contract calling for only $200 a month by "Bob” Brown of Vancouver. As tho Northwestern league season lasts five and one-half months, compared to tho Coast league’s seven months, Raleigh’s salary was cut in both ends. Brown showed no inclination to raise his salary figures, so Raleigh listened to the talk of tho owner of the Bingham mine. He will work in the mine and pitch one game of ball a week, for which he will draw $275 a month. The ball season lasts as long as the Northwestern circuit plays and the mine position is an all-the-year-round affair.

The Mount Elliott Mining Complex is an aggregation of the remnants of copper mining and smelting operations from the early 20th century and the associated former mining township of Selwyn. The earliest copper mining at Mount Elliott was in 1906 with smelting operations commencing shortly after. Significant upgrades to the mining and smelting operations occurred under the management of W.R. Corbould during 1909 - 1910. Following these upgrades and increases in production, the Selwyn Township grew quickly and had 1500 residents by 1918. The Mount Elliott Company took over other companies on the Cloncurry field in the 1920s, including the Mount Cuthbert and Kuridala smelters. Mount Elliott operations were taken over by Mount Isa Mines in 1943 to ensure the supply of copper during World War Two. The Mount Elliott Company was eventually liquidated in 1953.
The Mount Elliott Smelter:
The existence of copper in the Leichhardt River area of north western Queensland had been known since Ernest Henry discovered the Great Australia Mine in 1867 at Cloncurry. In 1899 James Elliott discovered copper on the conical hill that became Mount Elliott, but having no capital to develop the mine, he sold an interest to James Morphett, a pastoralist of Fort Constantine station near Cloncurry. Morphett, being drought stricken, in turn sold out to John Moffat of Irvinebank, the most successful mining promoter in Queensland at the time.
Plentiful capital and cheap transport were prerequisites for developing the Cloncurry field, which had stagnated for forty years. Without capital it was impossible to explore and prove ore-bodies; without proof of large reserves of wealth it was futile to build a railway; and without a railway it was hazardous to invest capital in finding large reserves of ore. The mining investor or the railway builder had to break the impasse.
In 1906 - 1907 copper averaged £87 a ton on the London market, the highest price for thirty years, and the Cloncurry field grew. The railway was extended west of Richmond in 1905 - 1906 by the Government and mines were floated on the Melbourne Stock Exchange. At Mount Elliott a prospecting shaft had been sunk and on the 1st of August 1906 a Cornish boiler and winding plant were installed on the site.
Mount Elliott Limited was floated in Melbourne on the 13th of July 1906. In 1907 it was taken over by British and French interests and restructured. Combining with its competitor, Hampden Cloncurry Copper Mines Limited, Mount Elliott formed a special company to finance and construct the railway from Cloncurry to Malbon, Kuridala (then Friezeland) and Mount Elliott (later Selwyn). This new company then entered into an agreement with the Queensland Railways Department in July 1908.
The railway, which was known as the 'Syndicate Railway', aroused opposition in 1908 from the trade unions and Labor movement generally, who contended that railways should be State-owned. However, the Hampden-Mount Elliott Railway Bill was passed by the Queensland Parliament and assented to on the 21st of April 1908; construction finished in December 1910. The railway terminated at the Mount Elliott smelter.
By 1907 the main underlie shaft had been sunk and construction of the smelters was underway using a second-hand water-jacket blast furnace and converters. At this time, W.H. Corbould was appointed general manager of Mount Elliott Limited.
The second-hand blast furnace and converters were commissioned or 'blown in' in May 1909, but were problematic causing hold-ups. Corbould referred to the equipment in use as being the 'worst collection of worn-out junk he had ever come across'. Corbould soon convinced his directors to scrap the plant and let him design new works.
Corbould was a metallurgist and geologist as well as mine/smelter manager. He foresaw a need to obtain control and thereby ensure a reliable supply of ore from a cross-section of mines in the region. He also saw a need to implement an effective strategy to manage the economies of smelting low-grade ore. Smelting operations in the region were made difficult by the technical and economic problems posed by the deterioration in the grade of ore. Corbould resolved the issue by a process of blending ores with different chemical properties, increasing the throughput capacity of the smelter and by championing the unification of smelting operations in the region. In 1912, Corbould acquired Hampden Consols Mine at Kuridala for Mount Elliott Limited, followed with the purchases of other small mines in the district.
Walkers Limited of Maryborough was commissioned to manufacture a new 200 ton water jacket furnace for the smelters. An air compressor and blower for the smelters were constructed in the powerhouse and an electric motor and dynamo provided power for the crane and lighting for the smelter and mine.
The new smelter was blown in September 1910, a month after the first train arrived, and it ran well, producing 2040 tons of blister copper by the end of the year. The new smelting plant made it possible to cope with low-grade sulphide ores at Mount Elliott. The use of 1000 tons of low-grade sulphide ores bought from the Hampden Consols Mine in 1911 made it clear that if a supply of higher sulphur ore could be obtained and blended, performance, and economy would improve. Accordingly, the company bought a number of smaller mines in the district in 1912.
Corbould mined with cut and fill stoping but a young Mines Inspector condemned the system, ordered it dismantled and replaced with square set timbering. In 1911, after gradual movement in stopes on the No. 3 level, the smelter was closed for two months. Nevertheless, 5447 tons of blister copper was produced in 1911, rising to 6690 tons in 1912 - the company's best year. Many of the surviving structures at the site were built at this time.
Troubles for Mount Elliott started in 1913. In February, a fire at the Consols Mine closed it for months. In June, a thirteen week strike closed the whole operation, severely depleting the workforce. The year 1913 was also bad for industrial accidents in the area, possibly due to inexperienced people replacing the strikers. Nevertheless, the company paid generous dividends that year.
At the end of 1914 smelting ceased for more than a year due to shortage of ore. Although 3200 tons of blister copper was produced in 1913, production fell to 1840 tons in 1914 and the workforce dwindled to only 40 men. For the second half of 1915 and early 1916 the smelter treated ore railed south from Mount Cuthbert. At the end of July 1916 the smelting plant at Selwyn was dismantled except for the flue chambers and stacks. A new furnace with a capacity of 500 tons per day was built, a large amount of second-hand equipment was obtained and the converters were increased in size.
After the enlarged furnace was commissioned in June 1917, continuing industrial unrest retarded production which amounted to only 1000 tons of copper that year. The point of contention was the efficiency of the new smelter which processed twice as much ore while employing fewer men. The company decided to close down the smelter in October and reduce the size of the furnace, the largest in Australia, from 6.5m to 5.5m. In the meantime the price of copper had almost doubled from 1916 due to wartime consumption of munitions.
The new furnace commenced on the 16th of January 1918 and 77,482 tons of ore were smelted yielding 3580 tons of blister copper which were sent to the Bowen refinery before export to Britain. Local coal and coke supply was a problem and materials were being sourced from the distant Bowen Colliery. The smelter had a good run for almost a year except for a strike in July and another in December, which caused Corbould to close down the plant until New Year. In 1919, following relaxation of wartime controls by the British Metal Corporation, the copper price plunged from about £110 per ton at the start of the year to £75 per ton in April, dashing the company's optimism regarding treatment of low grade ores. The smelter finally closed after two months operation and most employees were laid off.
For much of the period 1919 to 1922, Corbould was in England trying to raise capital to reorganise the company's operations but he failed and resigned from the company in 1922. The Mount Elliott Company took over the assets of the other companies on the Cloncurry field in the 1920s - Mount Cuthbert in 1925 and Kuridala in 1926. Mount Isa Mines bought the Mount Elliott plant and machinery, including the three smelters, in 1943 for £2,300, enabling them to start copper production in the middle of the Second World War. The Mount Elliott Company was finally liquidated in 1953.
In 1950 A.E. Powell took up the Mount Elliott Reward Claim at Selwyn and worked close to the old smelter buildings. An open cut mine commenced at Starra, south of Mount Elliott and Selwyn, in 1988 and is Australia's third largest copper producer producing copper-gold concentrates from flotation and gold bullion from carbon-in-leach processing.
Profitable copper-gold ore bodies were recently proved at depth beneath the Mount Elliott smelter and old underground workings by Cyprus Gold Australia Pty Ltd. These deposits were subsequently acquired by Arimco Mining Pty Ltd for underground development which commenced in July 1993. A decline tunnel portal, ore and overburden dumps now occupy a large area of the Maggie Creek valley south-west of the smelter which was formerly the site of early miner's camps.
The Old Selwyn Township:
In 1907, the first hotel, run by H. Williams, was opened at the site. The township was surveyed later, around 1910, by the Mines Department. The town was to be situated north of the mine and smelter operations adjacent the railway, about 1.5km distant. It took its name from the nearby Selwyn Ranges which were named, during Burke's expedition, after the Victorian Government Geologist, A.R. Selwyn. The town has also been known by the name of Mount Elliott, after the nearby mines and smelter.
Many of the residents either worked at the Mount Elliott Mine and Smelter or worked in the service industries which grew around the mining and smelting operations. Little documentation exists about the everyday life of the town's residents. Surrounding sheep and cattle stations, however, meant that meat was available cheaply and vegetables grown in the area were delivered to the township by horse and cart. Imported commodities were, however, expensive.
By 1910 the town had four hotels. There was also an aerated water manufacturer, three stores, four fruiterers, a butcher, baker, saddler, garage, police, hospital, banks, post office (officially from 1906 to 1928, then unofficially until 1975) and a railway station. There was even an orchestra of ten players in 1912. The population of Selwyn rose from 1000 in 1911 to 1500 in 1918, before gradually declining.

Combining with its competitor, Hampden Cloncurry Copper Mines Limited, Mount Elliott formed a special company to finance and construct the railway from Cloncurry to Malbon, Kuridala (then Friezeland) and Mount Elliott (later Selwyn). This new company then entered into an agreement with the Queensland Railways Department in July 1908.
The railway, which was known as the 'Syndicate Railway', aroused opposition in 1908 from the trade unions and Labor movement generally, who contended that railways should be State-owned. However, the Hampden-Mount Elliott Railway Bill was passed by the Queensland Parliament and assented to on the 21st of April 1908; construction finished in December 1910. The railway terminated at the Mount Elliott smelter.
By 1907 the main underlie shaft had been sunk and construction of the smelters was underway using a second-hand water-jacket blast furnace and converters. At this time, W.H. Corbould was appointed general manager of Mount Elliott Limited.
The second-hand blast furnace and converters were commissioned or 'blown in' in May 1909, but were problematic causing hold-ups. Corbould referred to the equipment in use as being the 'worst collection of worn-out junk he had ever come across'. Corbould soon convinced his directors to scrap the plant and let him design new works.
Corbould was a metallurgist and geologist as well as mine/smelter manager. He foresaw a need to obtain control and thereby ensure a reliable supply of ore from a cross-section of mines in the region. He also saw a need to implement an effective strategy to manage the economies of smelting low-grade ore. Smelting operations in the region were made difficult by the technical and economic problems posed by the deterioration in the grade of ore. Corbould resolved the issue by a process of blending ores with different chemical properties, increasing the throughput capacity of the smelter and by championing the unification of smelting operations in the region. In 1912, Corbould acquired Hampden Consols Mine at Kuridala for Mount Elliott Limited, followed with the purchases of other small mines in the district.
Walkers Limited of Maryborough was commissioned to manufacture a new 200 ton water jacket furnace for the smelters. An air compressor and blower for the smelters were constructed in the powerhouse and an electric motor and dynamo provided power for the crane and lighting for the smelter and mine.
The new smelter was blown in September 1910, a month after the first train arrived, and it ran well, producing 2040 tons of blister copper by the end of the year. The new smelting plant made it possible to cope with low-grade sulphide ores at Mount Elliott. The use of 1000 tons of low-grade sulphide ores bought from the Hampden Consols Mine in 1911 made it clear that if a supply of higher sulphur ore could be obtained and blended, performance, and economy would improve. Accordingly, the company bought a number of smaller mines in the district in 1912.
Corbould mined with cut and fill stoping but a young Mines Inspector condemned the system, ordered it dismantled and replaced with square set timbering. In 1911, after gradual movement in stopes on the No. 3 level, the smelter was closed for two months. Nevertheless, 5447 tons of blister copper was produced in 1911, rising to 6690 tons in 1912 - the company's best year. Many of the surviving structures at the site were built at this time.
Troubles for Mount Elliott started in 1913. In February, a fire at the Consols Mine closed it for months. In June, a thirteen week strike closed the whole operation, severely depleting the workforce. The year 1913 was also bad for industrial accidents in the area, possibly due to inexperienced people replacing the strikers. Nevertheless, the company paid generous dividends that year.
At the end of 1914 smelting ceased for more than a year due to shortage of ore. Although 3200 tons of blister copper was produced in 1913, production fell to 1840 tons in 1914 and the workforce dwindled to only 40 men. For the second half of 1915 and early 1916 the smelter treated ore railed south from Mount Cuthbert. At the end of July 1916 the smelting plant at Selwyn was dismantled except for the flue chambers and stacks. A new furnace with a capacity of 500 tons per day was built, a large amount of second-hand equipment was obtained and the converters were increased in size.
After the enlarged furnace was commissioned in June 1917, continuing industrial unrest retarded production which amounted to only 1000 tons of copper that year. The point of contention was the efficiency of the new smelter which processed twice as much ore while employing fewer men. The company decided to close down the smelter in October and reduce the size of the furnace, the largest in Australia, from 6.5m to 5.5m. In the meantime the price of copper had almost doubled from 1916 due to wartime consumption of munitions.
The new furnace commenced on the 16th of January 1918 and 77,482 tons of ore were smelted yielding 3580 tons of blister copper which were sent to the Bowen refinery before export to Britain. Local coal and coke supply was a problem and materials were being sourced from the distant Bowen Colliery. The smelter had a good run for almost a year except for a strike in July and another in December, which caused Corbould to close down the plant until New Year. In 1919, following relaxation of wartime controls by the British Metal Corporation, the copper price plunged from about £110 per ton at the start of the year to £75 per ton in April, dashing the company's optimism regarding treatment of low grade ores. The smelter finally closed after two months operation and most employees were laid off.
For much of the period 1919 to 1922, Corbould was in England trying to raise capital to reorganise the company's operations but he failed and resigned from the company in 1922. The Mount Elliott Company took over the assets of the other companies on the Cloncurry field in the 1920s - Mount Cuthbert in 1925 and Kuridala in 1926. Mount Isa Mines bought the Mount Elliott plant and machinery, including the three smelters, in 1943 for £2,300, enabling them to start copper production in the middle of the Second World War. The Mount Elliott Company was finally liquidated in 1953.
In 1950 A.E. Powell took up the Mount Elliott Reward Claim at Selwyn and worked close to the old smelter buildings. An open cut mine commenced at Starra, south of Mount Elliott and Selwyn, in 1988 and is Australia's third largest copper producer producing copper-gold concentrates from flotation and gold bullion from carbon-in-leach processing.
Profitable copper-gold ore bodies were recently proved at depth beneath the Mount Elliott smelter and old underground workings by Cyprus Gold Australia Pty Ltd. These deposits were subsequently acquired by Arimco Mining Pty Ltd for underground development which commenced in July 1993. A decline tunnel portal, ore and overburden dumps now occupy a large area of the Maggie Creek valley south-west of the smelter which was formerly the site of early miner's camps.
The Old Selwyn Township:
In 1907, the first hotel, run by H. Williams, was opened at the site. The township was surveyed later, around 1910, by the Mines Department. The town was to be situated north of the mine and smelter operations adjacent the railway, about 1.5km distant. It took its name from the nearby Selwyn Ranges which were named, during Burke's expedition, after the Victorian Government Geologist, A.R. Selwyn. The town has also been known by the name of Mount Elliott, after the nearby mines and smelter.
Many of the residents either worked at the Mount Elliott Mine and Smelter or worked in the service industries which grew around the mining and smelting operations. Little documentation exists about the everyday life of the town's residents. Surrounding sheep and cattle stations, however, meant that meat was available cheaply and vegetables grown in the area were delivered to the township by horse and cart. Imported commodities were, however, expensive.
By 1910 the town had four hotels. There was also an aerated water manufacturer, three stores, four fruiterers, a butcher, baker, saddler, garage, police, hospital, banks, post office (officially from 1906 to 1928, then unofficially until 1975) and a railway station. There was even an orchestra of ten players in 1912. The population of Selwyn rose from 1000 in 1911 to 1500 in 1918, before gradually declining.

Snow Geese by the thousands start arriving from the Arctic in early October. Typically between 60 to 120 thousand Snow Geese migrate from Wrangel Island Russia to winter and feed in Washington's Skagit / Fraser Delta, 70,000 to 90,000 of those winter in North Puget Sound and stay until late March or early April.
The Fraser-Skagit Population Dynamic: "Snow geese that over-winter in northwest Washington comprise a unique population of intercontinental travelers shared by three countries: the United States, Canada and Russia. These snow geese make an arduous, annual flight to Russia's Chuckchi Sea, to breed on Wrangel Island off the north coast of Siberia. They are called the Fraser-Skagit population, because the same identification collaring/banding studies that disclosed details of their migration timing and itinerary, found that snow geese of this group had a high fidelity to one nesting site on Wrangel Island and to one wintering area, here. They stay apart from the other snow geese aggregations that nest separately on Wrangel and winter in California." ~ wdfw.wa.gov

Bombylius pygmaeus
Mud-puddling is the phenomenon mostly seen in butterflies and involves their aggregation on substrates like wet soil, dung and carrion to obtain nutrients such as salts and amino acids.
Lepidoptera (butterflies and moths) are diverse in their strategies to gather liquid nutrients. Typically, mud-puddling behavior takes place on wet soil. But even sweat on human skin may be attractive to butterflies. The most unusual sources include blood and tears.
This behaviour is restricted to males in many species. Males seem to benefit from the sodium uptake through mud-puddling behaviour with an increase in reproductive success. The collected sodium and amino acids are often transferred to the female with the spermatophore during mating as a nuptial gift. This nutrition also enhances the survival rate of the eggs.
There's a nesting aggregation of the Slender-bodied Digger Wasp (Crabro cribrarius) just 100m from our Staffordshire house. I went over yesterday to see if I could photograph any females returning with flies. They use them (including hoverflies and robberflies) to provision the brood chambers in their nest burrows.
There was not much interesting activity but this morning, a male was on our sitting-room window. I probably brought him home with me. They do tend to land on you!
Here's a shot showing the interesting fore-tibial "shields" that the male of this (and a couple of related) species exhibit. I've read that they pacify the females during mating, by placing them over their eyes.
NASA artist's concept of first stage separation/second stage ignition during the nighttime ascent of a Nova launch vehicle on a “Lunar Return Mission”, aka “Lunar Landing”. This stunning work was part of a presentation/paper entitled “A Rocket for Manned Lunar Exploration”, given by Milton W. Rosen and Francis C. Schwenk at the Tenth International Astronautical (Federation?) Congress in London, 31 August 1959.
The abstract:
"One of the significant human accomplishments of the next decade will be the manned exploration of the moon. Previously, the uncharted regions of the earth, the Arctic and Antarctic, the Amazon and Himalayas challenged the skill and fortitude of explorers. But these regions cannot long retain their status—the new frontier lies beyond the confines of our planet—on the nearest sizeable aggregation of matter in space—the moon.
Significantly, man’s exploration has been paced by his technical progress. The discovery of America was made possible by ships and sails of sufficient size and by advances, however crude, in the art of navigation. Oxygen masks made possible the conquest of Everest, and rockets—the exploration of the upper atmosphere.
The exploration of the moon is within view today. If it may be assumed that Project Mercury in the U.S.A. and similar efforts by the U.S.S.R. will establish that man can exist for limited periods of time in space, then a trip to the moon requires mainly the design, construction and proving of a large rocket vehicle.
In one concept of a manned lunar vehicle the entire mission, the trip to the moon and the return, is staged on the earth’s surface. A highly competitive technique, one favored by many engineers, is to stage the lunar mission by refueling in a low earth orbit. This would permit the use of a smaller launching vehicle but would require development of orbital rendezvous techniques. In any case, a vehicle of the larger type will be needed for lunar as well as other exploratory missions.
This paper presents a parametric study of vehicle scale for the direct flight manned lunar mission. The main parameter is the take-off thrust which is influenced by many factors; principally the propellants in the several stages and the flight trajectory. A close choice exists in the second stage where conventional and high energy propellants are compared. The size of the final stage and hence the entire vehicle is governed mainly by the method of approach to the earth’s surface, whether it is elliptic, parabolic or hyperbolic. The various methods are applied to an illustrative vehicle configuration.
Reliability will be a major factor in the success of any manned lunar flight. While no formula is proposed for improving component reliability, certain operational procedures can be used to advantage in enhancing the probability of a successful round trip to the moon."
Some really cool things to take notice of:
Primarily, the parachute descent of the expended first stage - for recovery! Talk about forward-leaning thinking - reusability - in 1959! I thought the Saturn booster recovery concept (via Rogallo wing) evolved a few years later, damn.. VERY impressive.

Note the enigmatic terrain below, commensurate with the exotic launch site depicted in photo no. 219. I still maintain it’s Nova Scotia...Southern Nova Scotia of course. Get it, NOVA? Complete with the destination beckoning in the sky.
Note also the folded up/retracted landing gear with its footpads ringing the conical-shaped lander. However, ignore the fact the nearer footpad is facing the wrong direction (I think) and the two on the sides, although correctly oriented, probably should’ve been ripped off during max-Q. Minor stuff that in no way detracts, just the observation of a pathetic old(er) man.
Finally, windows and a hatch are visible, along with what might be a separation plane or hinge-line near the apex.
Again, this is 1959, I love it.

Francis C. Schwenk, possibly originally of the Lewis Flight Propulsion Laboratory/Lewis Research Center (btw, Cleveland Rocks) appears to have been a prolific researcher & valued asset to NACA/NASA. He even worked on the Satellite Power System concept, as late as 1980! Super smart, motivated, with longevity; traits you want in a rocket scientist. Also the real deal.
Being part of a NASA presentation, I assume this to be an in-house NASA work, which pretty much kills the chance of artist identification, especially for something from 1959. Damnit.

The red-wattled lapwing (Vanellus indicus) is an Asian lapwing or large plover, a wader in the family Charadriidae. Like other lapwings they are ground birds that are incapable of perching. Their characteristic loud alarm calls are indicators of human or animal movements and the sounds have been variously rendered as did he do it or pity to do it[ leading to the colloquial name of did-he-do-it bird. Usually seen in pairs or small groups and usually not far from water they sometimes form large aggregations in the non-breeding season (winter). They nest in a ground scrape laying three to four camouflaged eggs. Adults near the nest fly around, diving at potential predators while calling noisily. The cryptically patterned chicks hatch and immediately follow their parents to feed, hiding by lying low on the ground or in the grass when threatened.
Taxonomy:
Traditionally well-known to native hunters, the red-wattled lapwing was first described in a book by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1781. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle produced uinder the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert used the binomial name Tringa indica in his catalogue of the Planche Enluminées. The type locality is Goa in western India. It was subsequently placed in various other genera such as Sarcogrammus and Lobivanellus before being merged into Vanellus which was erected by the French zoologist Mathurin Jacques Brisson in 1760. Vanellus is the Medieval Latin for a "lapwing". It is a diminutive of the Latin vanus meaning "winnowing" or "fan". The specific epithet indicus is the Latin for "India".
Across their wide range there are slight differences in the plumage and there are four recognized subspecies:
V. i. aigneri (Laubmann, 1913) – southeast Turkey to Pakistan
V. i. indicus (Boddaert, 1783) – central Pakistan to Nepal, northeast India and Bangladesh
V. i. lankae (Koelz, 1939) – Sri Lanka
V. i. atronuchalis (Jerdon, 1864) – northeast India to south China, southeast Asia, Malay Peninsula and north Sumatra.
Description:
Red-wattled lapwings are large waders, about 35 cm (14 in) long. The wings and back are light brown with a purple to green sheen, but the head, a bib on the front and back of the neck are black. Prominently white patch runs between these two colours, from belly and tail, flanking the neck to the sides of crown. Short tail is tipped black. A red fleshy wattle in front of each eye, black-tipped red bill, and the long legs are yellow. In flight, prominent white wing bars formed by the white on the secondary coverts..
Race aigneri is slightly paler and larger than the nominate race and is found in Turkey, Iran, Iraq, Afghanistan and the Indus valley. The nominate race is found all over India. The Sri Lankan race lankae is smaller and dark while atronuchalis the race in north-eastern India and eastern Bangladesh has a white cheek surrounded by black.
Males and females are similar in plumage but males have a 5% longer wing and tend to have a longer carpal spur. The length of the birds is 320-350mm, wing of 208-247mm with the nominate averaging 223mm, Sri Lanka 217mm. The Bill is 31-36mm and tarsus of 70-83mm. Tail length is 104-128mm.
It usually keeps in pairs or trios in well-watered open country, ploughed fields, grazing land, and margins and dry beds of tanks and puddles. They occasionally form large flocks, ranging from 26 to 200 birds. It is also found in forest clearings around rain-filled depressions. It runs about in short spurts and dips forward obliquely (with unflexed legs) to pick up food in a typical plover manner. They are said to feed at night being especially active around the full moon. Is uncannily and ceaselessly vigilant, day or night, and is the first to detect intrusions and raise an alarm, and was therefore considered a nuisance by hunters. Flight rather slow, with deliberate flaps, but capable of remarkable agility when defending nest or being hunted by a hawk.
Its striking appearance is supplemented by its noisy nature, with a loud and scolding did-he-do-it call, uttered both in the day and night.
Leucistic abnormal plumages have been noted.
The local names are mainly onomatopoeic in origin and include titeeri (Hindi), tittibha (Kannada), tateehar (Sindhi), titodi (Gujarati), hatatut (Kashmiri), balighora (Assamese), yennappa chitawa (Telugu), aal-kaati (Tamil, meaning "human indicator").
Distribution:
It breeds from West Asia (Iraq, SW Iran, Persian Gulf) eastwards across South Asia (Baluchistan, Afghanistan, Pakistan, the entire Indian subcontinent up to Kanyakumari and up to 1800m in Kashmir/Nepal), with another sub-species further east in Southeast Asia. May migrate altitudinally in spring and autumn (e.g. in N. Baluchistan or NW Pakistan), and spreads out widely in the monsoons[13] on creation of requisite habitats, but by and large the populations are resident.
This species is declining in its western range, but is abundant in much of South Asia, being seen at almost any wetland habitat in its range.
Behaviour and ecology:
The breeding season is mainly March to August. The courtship involves the male puffing its feathers and pointing its beak upwards. The male then shuffles around the female. Several males may display to females and they may be close together. The eggs are laid in a ground scrape or depression sometimes fringed with pebbles, goat or hare droppings.[19] About 3–4 black-blotched buff eggs shaped a bit like a peg-top (pyriform), 42x30 mm on average. Nests are difficult to find since the eggs are cryptically coloured and usually matches the ground pattern. In residential areas, they sometimes take to nesting on roof-tops. They have been recorded nesting on the stones between the rails of a railway track, the adult leaving the nest when trains passed. Nests that have been threatened by agricultural operations have been manually translocated by gradually shifting the eggs. When nesting they will attempt to dive bomb or distract potential predators. Both the male and female incubate the eggs and divert predators using distraction displays or flash their wings to deter any herbivores that threaten the nest. Males appear to relieve females incubating at the nest particularly towards the hot part of noon. The eggs hatch in 28 to 30 days. The reproductive success is about 40%. Egg mortality is high (~43%) due to predation by mongooses, crows and kites. Chicks had a lower mortality (8.3%) and their survival improved after the first week.
Like other lapwings, they soak their belly feathers to provide water to their chicks as well as to cool the eggs during hot weather.
The chick leaves the nest and follows the parents soon after hatching
They bathe in pools of water when available and will often spend time on preening when leaving the nest or after copulation. They sometimes rest on the ground with the tarsi laid flat on the ground and at other times may rest on one leg.
Healthy adult birds have few predators and are capable of rapid and agile flight when pursued by hawks or falcons.Some endoparasitic tapeworms and trematodes have been described from the species. Mortality caused by respiratory infection by Ornithobacterium rhinotracheale has been recorded in captive birds in Pakistan.
Diet:
The diet of the lapwing includes a range of insects, snails and other invertebrates, mostly picked from the ground. They may also feed on some grains. They feed mainly during the day but they may also feed at night. They may sometimes make use of the legs to disturb insect prey from soft soil.
In culture:
In parts of India, a local belief is that the bird sleeps on its back with the legs upwards and an associated Hindi metaphor Tithiri se asman thama jayega ("can the lapwing support the heavens?") is used to refer to persons undertaking tasks beyond their ability or strength.
In parts of Rajasthan it is believed that the laying of eggs by the lapwing on high ground was an indication of good rains to come. The eggs are known to be collected by practitioners of folk medicine.
The Mount Elliott Mining Complex is an aggregation of the remnants of copper mining and smelting operations from the early 20th century and the associated former mining township of Selwyn. The earliest copper mining at Mount Elliott was in 1906 with smelting operations commencing shortly after. Significant upgrades to the mining and smelting operations occurred under the management of W.R. Corbould during 1909 - 1910. Following these upgrades and increases in production, the Selwyn Township grew quickly and had 1500 residents by 1918. The Mount Elliott Company took over other companies on the Cloncurry field in the 1920s, including the Mount Cuthbert and Kuridala smelters. Mount Elliott operations were taken over by Mount Isa Mines in 1943 to ensure the supply of copper during World War Two. The Mount Elliott Company was eventually liquidated in 1953.
The Mount Elliott Smelter:
The existence of copper in the Leichhardt River area of north western Queensland had been known since Ernest Henry discovered the Great Australia Mine in 1867 at Cloncurry. In 1899 James Elliott discovered copper on the conical hill that became Mount Elliott, but having no capital to develop the mine, he sold an interest to James Morphett, a pastoralist of Fort Constantine station near Cloncurry. Morphett, being drought stricken, in turn sold out to John Moffat of Irvinebank, the most successful mining promoter in Queensland at the time.
Plentiful capital and cheap transport were prerequisites for developing the Cloncurry field, which had stagnated for forty years. Without capital it was impossible to explore and prove ore-bodies; without proof of large reserves of wealth it was futile to build a railway; and without a railway it was hazardous to invest capital in finding large reserves of ore. The mining investor or the railway builder had to break the impasse.
In 1906 - 1907 copper averaged £87 a ton on the London market, the highest price for thirty years, and the Cloncurry field grew. The railway was extended west of Richmond in 1905 - 1906 by the Government and mines were floated on the Melbourne Stock Exchange. At Mount Elliott a prospecting shaft had been sunk and on the 1st of August 1906 a Cornish boiler and winding plant were installed on the site.
Mount Elliott Limited was floated in Melbourne on the 13th of July 1906. In 1907 it was taken over by British and French interests and restructured. Combining with its competitor, Hampden Cloncurry Copper Mines Limited, Mount Elliott formed a special company to finance and construct the railway from Cloncurry to Malbon, Kuridala (then Friezeland) and Mount Elliott (later Selwyn). This new company then entered into an agreement with the Queensland Railways Department in July 1908.
The railway, which was known as the 'Syndicate Railway', aroused opposition in 1908 from the trade unions and Labor movement generally, who contended that railways should be State-owned. However, the Hampden-Mount Elliott Railway Bill was passed by the Queensland Parliament and assented to on the 21st of April 1908; construction finished in December 1910. The railway terminated at the Mount Elliott smelter.
By 1907 the main underlie shaft had been sunk and construction of the smelters was underway using a second-hand water-jacket blast furnace and converters. At this time, W.H. Corbould was appointed general manager of Mount Elliott Limited.
The second-hand blast furnace and converters were commissioned or 'blown in' in May 1909, but were problematic causing hold-ups. Corbould referred to the equipment in use as being the 'worst collection of worn-out junk he had ever come across'. Corbould soon convinced his directors to scrap the plant and let him design new works.
Corbould was a metallurgist and geologist as well as mine/smelter manager. He foresaw a need to obtain control and thereby ensure a reliable supply of ore from a cross-section of mines in the region. He also saw a need to implement an effective strategy to manage the economies of smelting low-grade ore. Smelting operations in the region were made difficult by the technical and economic problems posed by the deterioration in the grade of ore. Corbould resolved the issue by a process of blending ores with different chemical properties, increasing the throughput capacity of the smelter and by championing the unification of smelting operations in the region. In 1912, Corbould acquired Hampden Consols Mine at Kuridala for Mount Elliott Limited, followed with the purchases of other small mines in the district.
Walkers Limited of Maryborough was commissioned to manufacture a new 200 ton water jacket furnace for the smelters. An air compressor and blower for the smelters were constructed in the powerhouse and an electric motor and dynamo provided power for the crane and lighting for the smelter and mine.
The new smelter was blown in September 1910, a month after the first train arrived, and it ran well, producing 2040 tons of blister copper by the end of the year. The new smelting plant made it possible to cope with low-grade sulphide ores at Mount Elliott. The use of 1000 tons of low-grade sulphide ores bought from the Hampden Consols Mine in 1911 made it clear that if a supply of higher sulphur ore could be obtained and blended, performance, and economy would improve. Accordingly, the company bought a number of smaller mines in the district in 1912.
Corbould mined with cut and fill stoping but a young Mines Inspector condemned the system, ordered it dismantled and replaced with square set timbering. In 1911, after gradual movement in stopes on the No. 3 level, the smelter was closed for two months. Nevertheless, 5447 tons of blister copper was produced in 1911, rising to 6690 tons in 1912 - the company's best year. Many of the surviving structures at the site were built at this time.
Troubles for Mount Elliott started in 1913. In February, a fire at the Consols Mine closed it for months. In June, a thirteen week strike closed the whole operation, severely depleting the workforce. The year 1913 was also bad for industrial accidents in the area, possibly due to inexperienced people replacing the strikers. Nevertheless, the company paid generous dividends that year.
At the end of 1914 smelting ceased for more than a year due to shortage of ore. Although 3200 tons of blister copper was produced in 1913, production fell to 1840 tons in 1914 and the workforce dwindled to only 40 men. For the second half of 1915 and early 1916 the smelter treated ore railed south from Mount Cuthbert. At the end of July 1916 the smelting plant at Selwyn was dismantled except for the flue chambers and stacks. A new furnace with a capacity of 500 tons per day was built, a large amount of second-hand equipment was obtained and the converters were increased in size.
After the enlarged furnace was commissioned in June 1917, continuing industrial unrest retarded production which amounted to only 1000 tons of copper that year. The point of contention was the efficiency of the new smelter which processed twice as much ore while employing fewer men. The company decided to close down the smelter in October and reduce the size of the furnace, the largest in Australia, from 6.5m to 5.5m. In the meantime the price of copper had almost doubled from 1916 due to wartime consumption of munitions.
The new furnace commenced on the 16th of January 1918 and 77,482 tons of ore were smelted yielding 3580 tons of blister copper which were sent to the Bowen refinery before export to Britain. Local coal and coke supply was a problem and materials were being sourced from the distant Bowen Colliery. The smelter had a good run for almost a year except for a strike in July and another in December, which caused Corbould to close down the plant until New Year. In 1919, following relaxation of wartime controls by the British Metal Corporation, the copper price plunged from about £110 per ton at the start of the year to £75 per ton in April, dashing the company's optimism regarding treatment of low grade ores. The smelter finally closed after two months operation and most employees were laid off.
For much of the period 1919 to 1922, Corbould was in England trying to raise capital to reorganise the company's operations but he failed and resigned from the company in 1922. The Mount Elliott Company took over the assets of the other companies on the Cloncurry field in the 1920s - Mount Cuthbert in 1925 and Kuridala in 1926. Mount Isa Mines bought the Mount Elliott plant and machinery, including the three smelters, in 1943 for £2,300, enabling them to start copper production in the middle of the Second World War. The Mount Elliott Company was finally liquidated in 1953.
In 1950 A.E. Powell took up the Mount Elliott Reward Claim at Selwyn and worked close to the old smelter buildings. An open cut mine commenced at Starra, south of Mount Elliott and Selwyn, in 1988 and is Australia's third largest copper producer producing copper-gold concentrates from flotation and gold bullion from carbon-in-leach processing.
Profitable copper-gold ore bodies were recently proved at depth beneath the Mount Elliott smelter and old underground workings by Cyprus Gold Australia Pty Ltd. These deposits were subsequently acquired by Arimco Mining Pty Ltd for underground development which commenced in July 1993. A decline tunnel portal, ore and overburden dumps now occupy a large area of the Maggie Creek valley south-west of the smelter which was formerly the site of early miner's camps.
The Old Selwyn Township:
In 1907, the first hotel, run by H. Williams, was opened at the site. The township was surveyed later, around 1910, by the Mines Department. The town was to be situated north of the mine and smelter operations adjacent the railway, about 1.5km distant. It took its name from the nearby Selwyn Ranges which were named, during Burke's expedition, after the Victorian Government Geologist, A.R. Selwyn. The town has also been known by the name of Mount Elliott, after the nearby mines and smelter.
Many of the residents either worked at the Mount Elliott Mine and Smelter or worked in the service industries which grew around the mining and smelting operations. Little documentation exists about the everyday life of the town's residents. Surrounding sheep and cattle stations, however, meant that meat was available cheaply and vegetables grown in the area were delivered to the township by horse and cart. Imported commodities were, however, expensive.
By 1910 the town had four hotels. There was also an aerated water manufacturer, three stores, four fruiterers, a butcher, baker, saddler, garage, police, hospital, banks, post office (officially from 1906 to 1928, then unofficially until 1975) and a railway station. There was even an orchestra of ten players in 1912. The population of Selwyn rose from 1000 in 1911 to 1500 in 1918, before gradually declining.

The Mount Elliott Mining Complex is an aggregation of the remnants of copper mining and smelting operations from the early 20th century and the associated former mining township of Selwyn. The earliest copper mining at Mount Elliott was in 1906 with smelting operations commencing shortly after. Significant upgrades to the mining and smelting operations occurred under the management of W.R. Corbould during 1909 - 1910. Following these upgrades and increases in production, the Selwyn Township grew quickly and had 1500 residents by 1918. The Mount Elliott Company took over other companies on the Cloncurry field in the 1920s, including the Mount Cuthbert and Kuridala smelters. Mount Elliott operations were taken over by Mount Isa Mines in 1943 to ensure the supply of copper during World War Two. The Mount Elliott Company was eventually liquidated in 1953.
The Mount Elliott Smelter:
The existence of copper in the Leichhardt River area of north western Queensland had been known since Ernest Henry discovered the Great Australia Mine in 1867 at Cloncurry. In 1899 James Elliott discovered copper on the conical hill that became Mount Elliott, but having no capital to develop the mine, he sold an interest to James Morphett, a pastoralist of Fort Constantine station near Cloncurry. Morphett, being drought stricken, in turn sold out to John Moffat of Irvinebank, the most successful mining promoter in Queensland at the time.
Plentiful capital and cheap transport were prerequisites for developing the Cloncurry field, which had stagnated for forty years. Without capital it was impossible to explore and prove ore-bodies; without proof of large reserves of wealth it was futile to build a railway; and without a railway it was hazardous to invest capital in finding large reserves of ore. The mining investor or the railway builder had to break the impasse.
In 1906 - 1907 copper averaged £87 a ton on the London market, the highest price for thirty years, and the Cloncurry field grew. The railway was extended west of Richmond in 1905 - 1906 by the Government and mines were floated on the Melbourne Stock Exchange. At Mount Elliott a prospecting shaft had been sunk and on the 1st of August 1906 a Cornish boiler and winding plant were installed on the site.
Mount Elliott Limited was floated in Melbourne on the 13th of July 1906. In 1907 it was taken over by British and French interests and restructured. Combining with its competitor, Hampden Cloncurry Copper Mines Limited, Mount Elliott formed a special company to finance and construct the railway from Cloncurry to Malbon, Kuridala (then Friezeland) and Mount Elliott (later Selwyn). This new company then entered into an agreement with the Queensland Railways Department in July 1908.
The railway, which was known as the 'Syndicate Railway', aroused opposition in 1908 from the trade unions and Labor movement generally, who contended that railways should be State-owned. However, the Hampden-Mount Elliott Railway Bill was passed by the Queensland Parliament and assented to on the 21st of April 1908; construction finished in December 1910. The railway terminated at the Mount Elliott smelter.
By 1907 the main underlie shaft had been sunk and construction of the smelters was underway using a second-hand water-jacket blast furnace and converters. At this time, W.H. Corbould was appointed general manager of Mount Elliott Limited.
The second-hand blast furnace and converters were commissioned or 'blown in' in May 1909, but were problematic causing hold-ups. Corbould referred to the equipment in use as being the 'worst collection of worn-out junk he had ever come across'. Corbould soon convinced his directors to scrap the plant and let him design new works.
Corbould was a metallurgist and geologist as well as mine/smelter manager. He foresaw a need to obtain control and thereby ensure a reliable supply of ore from a cross-section of mines in the region. He also saw a need to implement an effective strategy to manage the economies of smelting low-grade ore. Smelting operations in the region were made difficult by the technical and economic problems posed by the deterioration in the grade of ore. Corbould resolved the issue by a process of blending ores with different chemical properties, increasing the throughput capacity of the smelter and by championing the unification of smelting operations in the region. In 1912, Corbould acquired Hampden Consols Mine at Kuridala for Mount Elliott Limited, followed with the purchases of other small mines in the district.
Walkers Limited of Maryborough was commissioned to manufacture a new 200 ton water jacket furnace for the smelters. An air compressor and blower for the smelters were constructed in the powerhouse and an electric motor and dynamo provided power for the crane and lighting for the smelter and mine.
The new smelter was blown in September 1910, a month after the first train arrived, and it ran well, producing 2040 tons of blister copper by the end of the year. The new smelting plant made it possible to cope with low-grade sulphide ores at Mount Elliott. The use of 1000 tons of low-grade sulphide ores bought from the Hampden Consols Mine in 1911 made it clear that if a supply of higher sulphur ore could be obtained and blended, performance, and economy would improve. Accordingly, the company bought a number of smaller mines in the district in 1912.
Corbould mined with cut and fill stoping but a young Mines Inspector condemned the system, ordered it dismantled and replaced with square set timbering. In 1911, after gradual movement in stopes on the No. 3 level, the smelter was closed for two months. Nevertheless, 5447 tons of blister copper was produced in 1911, rising to 6690 tons in 1912 - the company's best year. Many of the surviving structures at the site were built at this time.
Troubles for Mount Elliott started in 1913. In February, a fire at the Consols Mine closed it for months. In June, a thirteen week strike closed the whole operation, severely depleting the workforce. The year 1913 was also bad for industrial accidents in the area, possibly due to inexperienced people replacing the strikers. Nevertheless, the company paid generous dividends that year.
At the end of 1914 smelting ceased for more than a year due to shortage of ore. Although 3200 tons of blister copper was produced in 1913, production fell to 1840 tons in 1914 and the workforce dwindled to only 40 men. For the second half of 1915 and early 1916 the smelter treated ore railed south from Mount Cuthbert. At the end of July 1916 the smelting plant at Selwyn was dismantled except for the flue chambers and stacks. A new furnace with a capacity of 500 tons per day was built, a large amount of second-hand equipment was obtained and the converters were increased in size.
After the enlarged furnace was commissioned in June 1917, continuing industrial unrest retarded production which amounted to only 1000 tons of copper that year. The point of contention was the efficiency of the new smelter which processed twice as much ore while employing fewer men. The company decided to close down the smelter in October and reduce the size of the furnace, the largest in Australia, from 6.5m to 5.5m.

The blue wildebeest, also called the common wildebeest, white-bearded wildebeest or brindled gnu, is a large antelope and one of the two species of wildebeest. It is a herbivore, feeding primarily on the short grasses. It forms herds which move about in loose aggregations, the animals being fast runners and extremely wary.

Giraffe
Kruger National Park is one of the largest game reserves in Africa. It covers an area of 19,485 km2 (7,523 sq mi) in the provinces of Limpopo and Mpumalanga in northeastern South Africa, and extends 360 km (220 mi) from north to south and 65 km (40 mi) from east to west. The administrative headquarters are in Skukuza. Areas of the park were first protected by the government of the South African Republic in 1898, and it became South Africa's first national park in 1926.
To the west and south of the Kruger National Park are the two South African provinces of Limpopo and Mpumalanga. In the north is Zimbabwe, and to the east is Mozambique. It is now part of the Great Limpopo Transfrontier Park, a peace park that links Kruger National Park with the Gonarezhou National Park in Zimbabwe, and with the Limpopo National Park in Mozambique.
The park is part of the Kruger to Canyons Biosphere an area designated by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as an International Man and Biosphere Reserve (the "Biosphere").
The park has nine main gates allowing entrance to the different camps.

The giraffe (Giraffa) is an African artiodactyl mammal, the tallest living terrestrial animal and the largest ruminant. It is traditionally considered to be one species, Giraffa camelopardalis, with nine subspecies. However, the existence of up to eight extant giraffe species has been described, based upon research into the mitochondrial and nuclear DNA, as well as morphological measurements of Giraffa. Seven other species are extinct, prehistoric species known from fossils.
The giraffe's chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its distinctive coat patterns. It is classified under the family Giraffidae, along with its closest extant relative, the okapi. Its scattered range extends from Chad in the north to South Africa in the south, and from Niger in the west to Somalia in the east. Giraffes usually inhabit savannahs and woodlands. Their food source is leaves, fruits and flowers of woody plants, primarily acacia species, which they browse at heights most other herbivores cannot reach. They may be preyed on by lions, leopards, spotted hyenas and African wild dogs. Giraffes live in herds of related females and their offspring, or bachelor herds of unrelated adult males, but are gregarious and may gather in large aggregations. Males establish social hierarchies through "necking", which are combat bouts where the neck is used as a weapon. Dominant males gain mating access to females, which bear the sole responsibility for raising the young.
The giraffe has intrigued various cultures, both ancient and modern, for its peculiar appearance, and has often been featured in paintings, books, and cartoons. It is classified by the International Union for Conservation of Nature as vulnerable to extinction, and has been extirpated from many parts of its former range. Giraffes are still found in numerous national parks and game reserves but estimates as of 2016 indicate that there are approximately 97,500 members of Giraffa in the wild. More than 1,600 were kept in zoos in 2010.
The name "giraffe" has its earliest known origins in the Arabic word zarāfah (زرافة), perhaps borrowed from the animal's Somali name geri. The Arab name is translated as "fast-walker". There were several Middle English spellings, such as jarraf, ziraph, and gerfauntz. The Italian form giraffa arose in the 1590s. The modern English form developed around 1600 from the French girafe. "Camelopard" is an archaic English name for the giraffe deriving from the Ancient Greek for camel and leopard, referring to its camel-like shape and its leopard-like colouring.
Fully grown giraffes stand 4.3–5.7 m (14.1–18.7 ft) tall, with males taller than females. The tallest recorded male was 5.88 m (19.3 ft) and the tallest recorded female was 5.17 m (17.0 ft) tall. The average weight is 1,192 kg (2,628 lb) for an adult male and 828 kg (1,825 lb) for an adult female with maximum weights of 1,930 kg (4,250 lb) and 1,180 kg (2,600 lb) having been recorded for males and females, respectively. Despite its long neck and legs, the giraffe's body is relatively short. Located at both sides of the head, the giraffe's large, bulging eyes give it good all-round vision from its great height. Giraffes see in colour and their senses of hearing and smell are also sharp. The animal can close its muscular nostrils to protect against sandstorms and ants.
The giraffe's prehensile tongue is about 45 cm (18 in) long. It is purplish-black in colour, perhaps to protect against sunburn, and is useful for grasping foliage, as well as for grooming and cleaning the animal's nose. The upper lip of the giraffe is also prehensile and useful when foraging and is covered in hair to protect against thorns. The tongue, and inside of the mouth are covered in papillae.
The coat has dark blotches or patches (which can be orange, chestnut, brown, or nearly black in colour) separated by light hair (usually white or cream in colour). Male giraffes become darker as they age. The coat pattern has been claimed to serve as camouflage in the light and shade patterns of savannah woodlands. Giraffe calves inherit some spot pattern traits from their mothers, and variation in some spot traits are correlated with neonatal survival. The skin underneath the dark areas may serve as windows for thermoregulation, being sites for complex blood vessel systems and large sweat glands. Each individual giraffe has a unique coat pattern.
The skin of a giraffe is mostly gray. Its thickness allows the animal to run through thorn bushes without being punctured. The fur may serve as a chemical defence, as its parasite repellents give the animal a characteristic scent. At least 11 main aromatic chemicals are in the fur, although indole and 3-methylindole are responsible for most of the smell. Because the males have a stronger odour than the females, the odour may also have sexual function. Along the animal's neck is a mane made of short, erect hairs. The one-metre (3.3-ft) tail ends in a long, dark tuft of hair and is used as a defense against insects.
Giraffes usually inhabit savannahs and open woodlands. They prefer Acacieae, Commiphora, Combretum and open Terminalia woodlands over denser environments like Brachystegia woodlands.The Angolan giraffe can be found in desert environments. Giraffes browse on the twigs of trees, preferring trees of the subfamily Acacieae and the genera Commiphora and Terminalia, which are important sources of calcium and protein to sustain the giraffe's growth rate. They also feed on shrubs, grass and fruit. A giraffe eats around 34 kg (75 lb) of foliage daily. When stressed, giraffes may chew the bark off branches. Although herbivorous, the giraffe has been known to visit carcasses and lick dried meat off bones.
During the wet season, food is abundant and giraffes are more spread out, while during the dry season, they gather around the remaining evergreen trees and bushes. Mothers tend to feed in open areas, presumably to make it easier to detect predators, although this may reduce their feeding efficiency. As a ruminant, the giraffe first chews its food, then swallows it for processing and then visibly passes the half-digested cud up the neck and back into the mouth to chew again. It is common for a giraffe to salivate while feeding. The giraffe requires less food than many other herbivores because the foliage it eats has more concentrated nutrients and it has a more efficient digestive system. The animal's faeces come in the form of small pellets. When it has access to water, a giraffe drinks at intervals no longer than three days.
Giraffes have a great effect on the trees that they feed on, delaying the growth of young trees for some years and giving "waistlines" to trees that are too tall. Feeding is at its highest during the first and last hours of daytime. Between these hours, giraffes mostly stand and ruminate. Rumination is the dominant activity during the night, when it is mostly done lying down.
Giraffes are usually found in groups that vary in size and composition according to ecological, anthropogenic, temporal, and social factors. Traditionally, the composition of these groups had been described as open and ever-changing. For research purposes, a "group" has been defined as "a collection of individuals that are less than a kilometre apart and moving in the same general direction." More recent studies have found that giraffes have long-term social associations and may form groups or pairs based on kinship, sex or other factors. These groups may regularly associate with one another in larger communities or sub-communities within a fission–fusion society. The number of giraffes in a group can range up to 66 individuals.
Giraffe groups tend to be sex-segregated although mixed-sex groups made of adult females and young males are known to occur. Particularly stable giraffe groups are those made of mothers and their young, which can last weeks or months. Social cohesion in these groups is maintained by the bonds formed between calves. Female association appears to be based on space-use and individuals may be matrilineally related. In general, females are more selective than males in who they associate with in regards to individuals of the same sex. Young males also form groups and will engage in playfights. However, as they get older males become more solitary but may also associate in pairs or with female groups. Giraffes are not territorial, but they have home ranges that vary according to rainfall and proximity to human settlements. Male giraffes occasionally wander far from areas that they normally frequent.
Although generally quiet and non-vocal, giraffes have been heard to communicate using various sounds. During courtship, males emit loud coughs. Females call their young by bellowing. Calves will emit snorts, bleats, mooing and mewing sounds. Giraffes also snore, hiss, moan, grunt and make flute-like sounds. During nighttime, giraffes appear to hum to each other above the infrasound range for purposes which are unclear.

Der Kruger-Nationalpark (deutsch häufig falsch Krüger-Nationalpark) ist das größte Wildschutzgebiet Südafrikas. Er liegt im Nordosten des Landes in der Landschaft des Lowveld auf dem Gebiet der Provinz Limpopo sowie des östlichen Abschnitts von Mpumalanga. Seine Fläche erstreckt sich vom Crocodile-River im Süden bis zum Limpopo, dem Grenzfluss zu Simbabwe, im Norden. Die Nord-Süd-Ausdehnung beträgt etwa 350 km, in Ost-West-Richtung ist der Park durchschnittlich 54 km breit und umfasst eine Fläche von rund 20.000 Quadratkilometern. Damit gehört er zu den größten Nationalparks in Afrika.
Das Schutzgebiet wurde am 26. März 1898 unter dem Präsidenten Paul Kruger als Sabie Game Reserve zum Schutz der Wildnis gegründet. 1926 erhielt das Gebiet den Status Nationalpark und wurde in seinen heutigen Namen umbenannt. Im Park leben 147 Säugetierarten inklusive der „Big Five“, außerdem etwa 507 Vogelarten und 114 Reptilienarten, 49 Fischarten und 34 Amphibienarten.

Die Giraffen (Giraffa) sind eine Gattung der Säugetiere aus der Ordnung der Paarhufer. Ursprünglich wurde ihr mit Giraffa camelopardalis und der Trivialbezeichnung „Giraffe“ nur eine einzige Art zugewiesen. Molekulargenetische Untersuchungen aus dem Jahr 2016 zeigen jedoch, dass die Gattung wenigstens vier Arten mit sieben eigenständigen Populationen umfasst. Die Giraffen stellen die höchsten landlebenden Tiere der Welt. Zur Unterscheidung vom verwandten Okapi (sogenannte „Waldgiraffe“) werden sie auch als Steppengiraffen bezeichnet.
Männchen (Bullen) werden bis zu 6 Meter hoch und wiegen durchschnittlich rund 1600 Kilogramm. Weibchen (Kühe) werden bis zu 4,5 Meter hoch und wiegen etwa 830 Kilogramm bei einer Schulterhöhe zwischen 2 und 3,5 Metern.
Der Hals der Giraffen ist außergewöhnlich lang. Wie bei fast allen Säugetieren besteht die Halswirbelsäule gleichwohl aus nur sieben Halswirbeln, die aber stark verlängert sind. Der Hals wird von einer einzigen, sehr starken Sehne in einem Winkel von etwa 55° gehalten. Die Sehne verläuft vom Hinterkopf der Giraffe bis zum Steiß und ist für den „Höcker“ zwischen Hals und Körper verantwortlich. Der Ruhezustand hält Hals und Kopf in der aufrechten Position; um den Kopf nach unten zu bewegen, z. B. zum Trinken, muss die Giraffe Muskelarbeit aufbringen. Die Zunge kann 50 Zentimeter lang werden. Sie ist zum Greifen befähigt und im vorderen Bereich zum Schutz vor Sonnenbrand stark pigmentiert.
Das Muster des Haarkleids besteht aus dunklen Flecken, die sich von der helleren Grundfarbe abheben. Je nach Art variieren Form und Farbe der Flecken. Die Unterseite ist hell und ungefleckt. Die Flecken dienen der Tarnung und der Regulierung der Körpertemperatur. Im Unterhautgewebe verläuft um jeden Flecken eine ringförmige Arterie, die Äste in den Flecken hinein aussendet. Über eine stärkere Durchblutung kann die Giraffe so mehr Körperwärme abgeben und ist nicht auf Schatten angewiesen. Vor allem bei männlichen Giraffen werden die Flecken mit zunehmenden Alter dunkler. Dies geschieht jedoch nicht bei allen Individuen im gleichen Maß oder in der gleichen Intensität, so dass hellere und dunklere Tiere in derselben Altersklasse auftreten. Nach Untersuchungen an Tieren aus dem Etosha-Nationalpark sind dunklere Altbullen häufig einzelgängerisch und zeichnen sich durch ein dominantes Auftreten gegenüber Geschlechtsgenossen bei der Fortpflanzung aus. Gleichalte hellere Individuen führen dagegen häufig ein Leben im Verband und sind weniger dominant, was zu geringeren Erfolgen in der Verpaarung mit Kühen führt. Demnach gibt die Fellfarbe den sozialen Status eines Individuums wieder.
Der Geruch des Haarkleids ist für den Menschen unangenehm. Giraffenbullen riechen stärker als -kühe. An Fäkalien erinnern speziell die Stoffe Indol und Skatol, darüber hinaus finden sich Octan, Benzaldehyd, Heptanal, Octanal, Nonanal, p-Kresol, Tetradecan- und Hexadecansäure im Fell. Die meisten dieser Verbindungen hemmen das Wachstum von Bakterien oder Pilzen, wie sie auf der Haut von Säugetieren vorkommen. Der Gehalt von p-Kresol im Giraffenhaar ist ausreichend, um Zecken abzuschrecken.
Zwei zapfenartige Hörner sitzen bei beiden Geschlechtern dem Kopf auf. In seltenen Fällen wächst dahinter ein weiteres Hornpaar. Manche Giraffen haben zudem einen knochigen Höcker zwischen den Augen, der ähnlich wie die Hörner strukturiert ist.
Giraffen erreichen eine Spitzengeschwindigkeit von 55 km/h. Die langen Beine können die Giraffe aber nur auf festem Untergrund tragen. Sumpfige Gegenden werden von den Tieren daher gemieden.
Giraffen verständigen sich im für Menschen nicht hörbaren Infraschallbereich mit Frequenzen unter 20 Hertz.
Giraffen sind in afrikanischen Savannen verbreitet. Heute leben sie nur noch südlich der Sahara, vor allem in den Grassteppen Ost- und Südafrikas. Die Bestände nördlich der Sahara wurden frühzeitig durch den Menschen ausgerottet: während des frühen Altertums im Niltal und etwa im 7. Jahrhundert in den Küstenebenen Marokkos und Algeriens. Im 20. Jahrhundert verschwanden Giraffen aus vielen weiteren Bereichen ihres Verbreitungsgebiets.
Giraffen beweiden bevorzugt Akazien. Dabei greifen die Tiere einen Zweig mit ihrer bis zu 50 cm langen Zunge, ziehen ihn ins Maul und streifen durch Zurückziehen des Kopfes die Blätter ab. Zunge und Lippen sind so beschaffen, dass sie trotz der dornigen Äste keinen Schaden nehmen. Durch die hohe Bisskraft und die massiven Mahlzähne können die Äste, Blätter und Zweige zügig kleingemahlen werden und rutschen innerhalb kürzester Zeit den bis zu 2,5 Meter langen Hals herab. Jeden Tag nimmt eine Giraffe etwa 30 kg Nahrung auf; hierfür benötigt sie sechzehn bis zwanzig Stunden. Der Flüssigkeitsbedarf wird größtenteils aus der Nahrung gedeckt, so dass Giraffen wochenlang ohne zu trinken auskommen können. Wenn sie doch trinken, müssen sie die Vorderbeine weit spreizen, um den Kopf weit genug zur Wasserquelle herabsenken zu können; ebenso verfahren sie, wenn sie Nahrung vom Boden aufnehmen, was sie allerdings nur unter sehr ungünstigen Umständen tun.
Giraffen leben einzelgängerisch oder in losen Verbänden. Dabei hängt das Sozialverhalten vom Geschlecht ab: Weibchen tun sich stets zu Herden von 4 bis 32 Tieren zusammen, die jedoch immer wieder in der Zusammensetzung wechseln. Junge oder weniger dominante Männchen formen eigene Verbände, sogenannte Junggesellengruppen, dominante Altbullen sind meist Einzelgänger. Die Gruppengröße ist abhängig vom Lebensraum und wird nicht durch die Anwesenheit größerer Beutegreifer beeinflusst. Auffälligerweise finden sich Kühe mit Nachwuchs häufiger in kleineren Gruppen zusammen. In der Namib im südwestlichen Afrika bilden gemischte Gruppen zumeist größere Verbände als eingeschlechtige Gruppen, wodurch die Geschlechterzusammensetzung einen wichtigen Einfluss darstellt. Demgegenüber nehmen Herden mit Jungtieren nicht an Größe zu, was den Schluss zulässt, dass bei den Giraffen der Schutz des Nachwuchses vor Bejagung nicht über die Gruppengröße gesteuert wird. Einen weiteren wichtigen Faktor bei der Herdenbildung stellt die räumliche Verfügbarkeit von Nahrung dar. Dieser greift aber nicht über die Jahreszeiten hinweg, wodurch Herden als relativ stabil angesehen werden können. Fluktuationen in der Herdengröße sind demnach vom Nahrungsangebot abhängig und können über Tage deutlich schwanken. So kommt es häufig in den Morgen- und Abendstunden zu größeren Zusammenschlüssen, die der gemeinsamen Nahrungsaufnahme dienen.
Treffen zwei Bullen aufeinander, kommt es meistens zu einem ritualisierten Kampf, bei dem die Tiere nebeneinander stehen und ihren Kopf gegen den Hals des Konkurrenten schlagen. Zur Paarungszeit können solche Kämpfe aggressiver ausfallen und eine Heftigkeit annehmen, bei der einer der Konkurrenten bewusstlos geschlagen wird.
Entgegen weit verbreiteter Meinung fressen Giraffen, vor allem in der Trockenzeit, von niedrigen Büschen bzw. auf halber Körperhöhe. Aus diesem Grund wird mittlerweile angezweifelt, dass die Giraffen ihren langen Hals nur aufgrund von Nahrungsauswahl haben. Ein Argument, das gegen die Nahrungsaufnahme-Theorie spricht, ist, dass Giraffen im Laufe der Evolution stärker ihren Hals verlängert haben als ihre Beine. Längere Beine wären jedoch energetisch günstiger, wenn es nur um Höhengewinn gehen würde. Eine aktuelle Theorie für den langen Hals sieht daher den Kampf der Giraffen-Männchen um Dominanz und Weibchen als einen Hauptgrund. Ein langer Hals ist dabei im Kampf vorteilhaft.
Giraffen schlafen mehrmals innerhalb eines 24-Stunden-Tages, dabei liegen sie mit angezogenen Beinen auf dem Bauch, mit dem Kopf nach hinten auf dem Körper. Der Schlaf dauert in der Regel nur kurze Zeit, in mehr als der Hälfte aller Beobachtungen weniger als 11 Minuten, im Maximum bis zu 100 Minuten. Die REM-Phase währt im Mittel 3 Minuten. Es wird angenommen, dass die Tiere in der liegenden Stellung Raubtieren schutzlos ausgeliefert sind, da sie nur langsam aufstehen können und sich durch Treten mit den Beinen verteidigen. Den größten Teil der Nacht verbringen sie mit Wiederkäuen. Tagsüber dösen Giraffen hin und wieder kurz im Stehen, was insgesamt weniger als 50 Minuten eines 24-Stunden-Tages ausmacht. Dadurch kommt ein Individuum auf etwa 4,6 Stunden Schlaf je Tageszyklus. Jungtiere schlafen durchschnittlich länger.

Rawlins Road, Fir Island - Snow Geese by the thousands start arriving from the Arctic in early October. Typically 70,000 to 90,000 winter in North Puget Sound until late March or April.
Fraser-Skagit Population Dynamic. "Snow geese that over-winter in northwest Washington comprise a unique population of intercontinental travelers shared by three countries: the United States, Canada and Russia. These snow geese make an arduous, annual flight to Russia’s Chuckchi Sea, to breed on Wrangel Island off the north coast of Siberia. They are called the Fraser-Skagit population, because the same identification collaring/banding studies that disclosed details of their migration timing and itinerary, found that snow geese of this group had a high fidelity to one nesting site on Wrangel Island and to one wintering area, here. They stay apart from the other snow geese aggregations that nest separately on Wrangel and winter in California." wdfw.wa.gov
NASA artist's concept of the crew capsule, at the onset of re-entry, nearing the completion of a “Lunar Return Mission”, aka “Lunar Landing”. The rendering was part of a presentation/paper entitled “A Rocket for Manned Lunar Exploration”, given by Milton W. Rosen and Francis C. Schwenk at the Tenth International Astronautical (Federation?) Congress in London, 31 August 1959.
The abstract:
"One of the significant human accomplishments of the next decade will be the manned exploration of the moon. Previously, the uncharted regions of the earth, the Arctic and Antarctic, the Amazon and Himalayas challenged the skill and fortitude of explorers. But these regions cannot long retain their status—the new frontier lies beyond the confines of our planet—on the nearest sizeable aggregation of matter in space—the moon.
Significantly, man’s exploration has been paced by his technical progress. The discovery of America was made possible by ships and sails of sufficient size and by advances, however crude, in the art of navigation. Oxygen masks made possible the conquest of Everest, and rockets—the exploration of the upper atmosphere.
The exploration of the moon is within view today. If it may be assumed that Project Mercury in the U.S.A. and similar efforts by the U.S.S.R. will establish that man can exist for limited periods of time in space, then a trip to the moon requires mainly the design, construction and proving of a large rocket vehicle.
In one concept of a manned lunar vehicle the entire mission, the trip to the moon and the return, is staged on the earth’s surface. A highly competitive technique, one favored by many engineers, is to stage the lunar mission by refueling in a low earth orbit. This would permit the use of a smaller launching vehicle but would require development of orbital rendezvous techniques. In any case, a vehicle of the larger type will be needed for lunar as well as other exploratory missions.
This paper presents a parametric study of vehicle scale for the direct flight manned lunar mission. The main parameter is the take-off thrust which is influenced by many factors; principally the propellants in the several stages and the flight trajectory. A close choice exists in the second stage where conventional and high energy propellants are compared. The size of the final stage and hence the entire vehicle is governed mainly by the method of approach to the earth’s surface, whether it is elliptic, parabolic or hyperbolic. The various methods are applied to an illustrative vehicle configuration.
Reliability will be a major factor in the success of any manned lunar flight. While no formula is proposed for improving component reliability, certain operational procedures can be used to advantage in enhancing the probability of a successful round trip to the moon."
Furthermore, the referenced M. W. Rosen is none other than Milton “Milt” Rosen, of Viking & Vanguard rocket ‘fame’. The real deal. Confirmation:

Francis C. Schwenk, originally of the Lewis Flight Propulsion Laboratory/Lewis Research Center (Cleveland Rocks btw) appears to have been a prolific researcher & valued asset to NACA/NASA. He even worked on the Satellite Power System concept, as late as 1980! Super smart, motivated, with longevity; traits you want in a rocket scientist. Also the real deal.
Being part of a NASA presentation, I assume this to be in-house NASA artwork, which substantially reduces the likelihood of artist identification, especially for something from 1959. Damnit.

Kruger National Park is one of the largest game reserves in Africa. It covers an area of 19,485 km2 (7,523 sq mi) in the provinces of Limpopo and Mpumalanga in northeastern South Africa, and extends 360 km (220 mi) from north to south and 65 km (40 mi) from east to west. The administrative headquarters are in Skukuza. Areas of the park were first protected by the government of the South African Republic in 1898, and it became South Africa's first national park in 1926.
To the west and south of the Kruger National Park are the two South African provinces of Limpopo and Mpumalanga. In the north is Zimbabwe, and to the east is Mozambique. It is now part of the Great Limpopo Transfrontier Park, a peace park that links Kruger National Park with the Gonarezhou National Park in Zimbabwe, and with the Limpopo National Park in Mozambique.
The park is part of the Kruger to Canyons Biosphere an area designated by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as an International Man and Biosphere Reserve (the "Biosphere").
The park has nine main gates allowing entrance to the different camps.

The giraffe (Giraffa) is an African artiodactyl mammal, the tallest living terrestrial animal and the largest ruminant. It is traditionally considered to be one species, Giraffa camelopardalis, with nine subspecies. However, the existence of up to eight extant giraffe species has been described, based upon research into the mitochondrial and nuclear DNA, as well as morphological measurements of Giraffa. Seven other species are extinct, prehistoric species known from fossils.
The giraffe's chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its distinctive coat patterns. It is classified under the family Giraffidae, along with its closest extant relative, the okapi. Its scattered range extends from Chad in the north to South Africa in the south, and from Niger in the west to Somalia in the east. Giraffes usually inhabit savannahs and woodlands. Their food source is leaves, fruits and flowers of woody plants, primarily acacia species, which they browse at heights most other herbivores cannot reach. They may be preyed on by lions, leopards, spotted hyenas and African wild dogs. Giraffes live in herds of related females and their offspring, or bachelor herds of unrelated adult males, but are gregarious and may gather in large aggregations. Males establish social hierarchies through "necking", which are combat bouts where the neck is used as a weapon. Dominant males gain mating access to females, which bear the sole responsibility for raising the young.
The giraffe has intrigued various cultures, both ancient and modern, for its peculiar appearance, and has often been featured in paintings, books, and cartoons. It is classified by the International Union for Conservation of Nature as vulnerable to extinction, and has been extirpated from many parts of its former range. Giraffes are still found in numerous national parks and game reserves but estimates as of 2016 indicate that there are approximately 97,500 members of Giraffa in the wild. More than 1,600 were kept in zoos in 2010.
The name "giraffe" has its earliest known origins in the Arabic word zarāfah (زرافة), perhaps borrowed from the animal's Somali name geri. The Arab name is translated as "fast-walker". There were several Middle English spellings, such as jarraf, ziraph, and gerfauntz. The Italian form giraffa arose in the 1590s. The modern English form developed around 1600 from the French girafe. "Camelopard" is an archaic English name for the giraffe deriving from the Ancient Greek for camel and leopard, referring to its camel-like shape and its leopard-like colouring.
Fully grown giraffes stand 4.3–5.7 m (14.1–18.7 ft) tall, with males taller than females. The tallest recorded male was 5.88 m (19.3 ft) and the tallest recorded female was 5.17 m (17.0 ft) tall. The average weight is 1,192 kg (2,628 lb) for an adult male and 828 kg (1,825 lb) for an adult female with maximum weights of 1,930 kg (4,250 lb) and 1,180 kg (2,600 lb) having been recorded for males and females, respectively. Despite its long neck and legs, the giraffe's body is relatively short. Located at both sides of the head, the giraffe's large, bulging eyes give it good all-round vision from its great height. Giraffes see in colour and their senses of hearing and smell are also sharp. The animal can close its muscular nostrils to protect against sandstorms and ants.
The giraffe's prehensile tongue is about 45 cm (18 in) long. It is purplish-black in colour, perhaps to protect against sunburn, and is useful for grasping foliage, as well as for grooming and cleaning the animal's nose. The upper lip of the giraffe is also prehensile and useful when foraging and is covered in hair to protect against thorns. The tongue, and inside of the mouth are covered in papillae.
The coat has dark blotches or patches (which can be orange, chestnut, brown, or nearly black in colour) separated by light hair (usually white or cream in colour). Male giraffes become darker as they age. The coat pattern has been claimed to serve as camouflage in the light and shade patterns of savannah woodlands. Giraffe calves inherit some spot pattern traits from their mothers, and variation in some spot traits are correlated with neonatal survival. The skin underneath the dark areas may serve as windows for thermoregulation, being sites for complex blood vessel systems and large sweat glands. Each individual giraffe has a unique coat pattern.
The skin of a giraffe is mostly gray. Its thickness allows the animal to run through thorn bushes without being punctured. The fur may serve as a chemical defence, as its parasite repellents give the animal a characteristic scent. At least 11 main aromatic chemicals are in the fur, although indole and 3-methylindole are responsible for most of the smell. Because the males have a stronger odour than the females, the odour may also have sexual function. Along the animal's neck is a mane made of short, erect hairs. The one-metre (3.3-ft) tail ends in a long, dark tuft of hair and is used as a defense against insects.
Giraffes usually inhabit savannahs and open woodlands. They prefer Acacieae, Commiphora, Combretum and open Terminalia woodlands over denser environments like Brachystegia woodlands.The Angolan giraffe can be found in desert environments. Giraffes browse on the twigs of trees, preferring trees of the subfamily Acacieae and the genera Commiphora and Terminalia, which are important sources of calcium and protein to sustain the giraffe's growth rate. They also feed on shrubs, grass and fruit. A giraffe eats around 34 kg (75 lb) of foliage daily. When stressed, giraffes may chew the bark off branches. Although herbivorous, the giraffe has been known to visit carcasses and lick dried meat off bones.
During the wet season, food is abundant and giraffes are more spread out, while during the dry season, they gather around the remaining evergreen trees and bushes. Mothers tend to feed in open areas, presumably to make it easier to detect predators, although this may reduce their feeding efficiency. As a ruminant, the giraffe first chews its food, then swallows it for processing and then visibly passes the half-digested cud up the neck and back into the mouth to chew again. It is common for a giraffe to salivate while feeding. The giraffe requires less food than many other herbivores because the foliage it eats has more concentrated nutrients and it has a more efficient digestive system. The animal's faeces come in the form of small pellets. When it has access to water, a giraffe drinks at intervals no longer than three days.
Giraffes have a great effect on the trees that they feed on, delaying the growth of young trees for some years and giving "waistlines" to trees that are too tall. Feeding is at its highest during the first and last hours of daytime. Between these hours, giraffes mostly stand and ruminate. Rumination is the dominant activity during the night, when it is mostly done lying down.
Giraffes are usually found in groups that vary in size and composition according to ecological, anthropogenic, temporal, and social factors. Traditionally, the composition of these groups had been described as open and ever-changing. For research purposes, a "group" has been defined as "a collection of individuals that are less than a kilometre apart and moving in the same general direction." More recent studies have found that giraffes have long-term social associations and may form groups or pairs based on kinship, sex or other factors. These groups may regularly associate with one another in larger communities or sub-communities within a fission–fusion society. The number of giraffes in a group can range up to 66 individuals.
Giraffe groups tend to be sex-segregated although mixed-sex groups made of adult females and young males are known to occur. Particularly stable giraffe groups are those made of mothers and their young, which can last weeks or months. Social cohesion in these groups is maintained by the bonds formed between calves. Female association appears to be based on space-use and individuals may be matrilineally related. In general, females are more selective than males in who they associate with in regards to individuals of the same sex. Young males also form groups and will engage in playfights. However, as they get older males become more solitary but may also associate in pairs or with female groups. Giraffes are not territorial, but they have home ranges that vary according to rainfall and proximity to human settlements. Male giraffes occasionally wander far from areas that they normally frequent.
Although generally quiet and non-vocal, giraffes have been heard to communicate using various sounds. During courtship, males emit loud coughs. Females call their young by bellowing. Calves will emit snorts, bleats, mooing and mewing sounds. Giraffes also snore, hiss, moan, grunt and make flute-like sounds. During nighttime, giraffes appear to hum to each other above the infrasound range for purposes which are unclear.

Der Kruger-Nationalpark (deutsch häufig falsch Krüger-Nationalpark) ist das größte Wildschutzgebiet Südafrikas. Er liegt im Nordosten des Landes in der Landschaft des Lowveld auf dem Gebiet der Provinz Limpopo sowie des östlichen Abschnitts von Mpumalanga. Seine Fläche erstreckt sich vom Crocodile-River im Süden bis zum Limpopo, dem Grenzfluss zu Simbabwe, im Norden. Die Nord-Süd-Ausdehnung beträgt etwa 350 km, in Ost-West-Richtung ist der Park durchschnittlich 54 km breit und umfasst eine Fläche von rund 20.000 Quadratkilometern. Damit gehört er zu den größten Nationalparks in Afrika.
Das Schutzgebiet wurde am 26. März 1898 unter dem Präsidenten Paul Kruger als Sabie Game Reserve zum Schutz der Wildnis gegründet. 1926 erhielt das Gebiet den Status Nationalpark und wurde in seinen heutigen Namen umbenannt. Im Park leben 147 Säugetierarten inklusive der „Big Five“, außerdem etwa 507 Vogelarten und 114 Reptilienarten, 49 Fischarten und 34 Amphibienarten.

Die Giraffen (Giraffa) sind eine Gattung der Säugetiere aus der Ordnung der Paarhufer. Ursprünglich wurde ihr mit Giraffa camelopardalis und der Trivialbezeichnung „Giraffe“ nur eine einzige Art zugewiesen. Molekulargenetische Untersuchungen aus dem Jahr 2016 zeigen jedoch, dass die Gattung wenigstens vier Arten mit sieben eigenständigen Populationen umfasst. Die Giraffen stellen die höchsten landlebenden Tiere der Welt. Zur Unterscheidung vom verwandten Okapi (sogenannte „Waldgiraffe“) werden sie auch als Steppengiraffen bezeichnet.
Männchen (Bullen) werden bis zu 6 Meter hoch und wiegen durchschnittlich rund 1600 Kilogramm. Weibchen (Kühe) werden bis zu 4,5 Meter hoch und wiegen etwa 830 Kilogramm bei einer Schulterhöhe zwischen 2 und 3,5 Metern.
Der Hals der Giraffen ist außergewöhnlich lang. Wie bei fast allen Säugetieren besteht die Halswirbelsäule gleichwohl aus nur sieben Halswirbeln, die aber stark verlängert sind. Der Hals wird von einer einzigen, sehr starken Sehne in einem Winkel von etwa 55° gehalten. Die Sehne verläuft vom Hinterkopf der Giraffe bis zum Steiß und ist für den „Höcker“ zwischen Hals und Körper verantwortlich. Der Ruhezustand hält Hals und Kopf in der aufrechten Position; um den Kopf nach unten zu bewegen, z. B. zum Trinken, muss die Giraffe Muskelarbeit aufbringen. Die Zunge kann 50 Zentimeter lang werden. Sie ist zum Greifen befähigt und im vorderen Bereich zum Schutz vor Sonnenbrand stark pigmentiert.
Das Muster des Haarkleids besteht aus dunklen Flecken, die sich von der helleren Grundfarbe abheben. Je nach Art variieren Form und Farbe der Flecken. Die Unterseite ist hell und ungefleckt. Die Flecken dienen der Tarnung und der Regulierung der Körpertemperatur. Im Unterhautgewebe verläuft um jeden Flecken eine ringförmige Arterie, die Äste in den Flecken hinein aussendet. Über eine stärkere Durchblutung kann die Giraffe so mehr Körperwärme abgeben und ist nicht auf Schatten angewiesen. Vor allem bei männlichen Giraffen werden die Flecken mit zunehmenden Alter dunkler. Dies geschieht jedoch nicht bei allen Individuen im gleichen Maß oder in der gleichen Intensität, so dass hellere und dunklere Tiere in derselben Altersklasse auftreten. Nach Untersuchungen an Tieren aus dem Etosha-Nationalpark sind dunklere Altbullen häufig einzelgängerisch und zeichnen sich durch ein dominantes Auftreten gegenüber Geschlechtsgenossen bei der Fortpflanzung aus. Gleichalte hellere Individuen führen dagegen häufig ein Leben im Verband und sind weniger dominant, was zu geringeren Erfolgen in der Verpaarung mit Kühen führt. Demnach gibt die Fellfarbe den sozialen Status eines Individuums wieder.
Der Geruch des Haarkleids ist für den Menschen unangenehm. Giraffenbullen riechen stärker als -kühe. An Fäkalien erinnern speziell die Stoffe Indol und Skatol, darüber hinaus finden sich Octan, Benzaldehyd, Heptanal, Octanal, Nonanal, p-Kresol, Tetradecan- und Hexadecansäure im Fell. Die meisten dieser Verbindungen hemmen das Wachstum von Bakterien oder Pilzen, wie sie auf der Haut von Säugetieren vorkommen. Der Gehalt von p-Kresol im Giraffenhaar ist ausreichend, um Zecken abzuschrecken.
Zwei zapfenartige Hörner sitzen bei beiden Geschlechtern dem Kopf auf. In seltenen Fällen wächst dahinter ein weiteres Hornpaar. Manche Giraffen haben zudem einen knochigen Höcker zwischen den Augen, der ähnlich wie die Hörner strukturiert ist.
Giraffen erreichen eine Spitzengeschwindigkeit von 55 km/h. Die langen Beine können die Giraffe aber nur auf festem Untergrund tragen. Sumpfige Gegenden werden von den Tieren daher gemieden.
Giraffen verständigen sich im für Menschen nicht hörbaren Infraschallbereich mit Frequenzen unter 20 Hertz.
Giraffen sind in afrikanischen Savannen verbreitet. Heute leben sie nur noch südlich der Sahara, vor allem in den Grassteppen Ost- und Südafrikas. Die Bestände nördlich der Sahara wurden frühzeitig durch den Menschen ausgerottet: während des frühen Altertums im Niltal und etwa im 7. Jahrhundert in den Küstenebenen Marokkos und Algeriens. Im 20. Jahrhundert verschwanden Giraffen aus vielen weiteren Bereichen ihres Verbreitungsgebiets.
Giraffen beweiden bevorzugt Akazien. Dabei greifen die Tiere einen Zweig mit ihrer bis zu 50 cm langen Zunge, ziehen ihn ins Maul und streifen durch Zurückziehen des Kopfes die Blätter ab. Zunge und Lippen sind so beschaffen, dass sie trotz der dornigen Äste keinen Schaden nehmen. Durch die hohe Bisskraft und die massiven Mahlzähne können die Äste, Blätter und Zweige zügig kleingemahlen werden und rutschen innerhalb kürzester Zeit den bis zu 2,5 Meter langen Hals herab. Jeden Tag nimmt eine Giraffe etwa 30 kg Nahrung auf; hierfür benötigt sie sechzehn bis zwanzig Stunden. Der Flüssigkeitsbedarf wird größtenteils aus der Nahrung gedeckt, so dass Giraffen wochenlang ohne zu trinken auskommen können. Wenn sie doch trinken, müssen sie die Vorderbeine weit spreizen, um den Kopf weit genug zur Wasserquelle herabsenken zu können; ebenso verfahren sie, wenn sie Nahrung vom Boden aufnehmen, was sie allerdings nur unter sehr ungünstigen Umständen tun.
Giraffen leben einzelgängerisch oder in losen Verbänden. Dabei hängt das Sozialverhalten vom Geschlecht ab: Weibchen tun sich stets zu Herden von 4 bis 32 Tieren zusammen, die jedoch immer wieder in der Zusammensetzung wechseln. Junge oder weniger dominante Männchen formen eigene Verbände, sogenannte Junggesellengruppen, dominante Altbullen sind meist Einzelgänger. Die Gruppengröße ist abhängig vom Lebensraum und wird nicht durch die Anwesenheit größerer Beutegreifer beeinflusst. Auffälligerweise finden sich Kühe mit Nachwuchs häufiger in kleineren Gruppen zusammen. In der Namib im südwestlichen Afrika bilden gemischte Gruppen zumeist größere Verbände als eingeschlechtige Gruppen, wodurch die Geschlechterzusammensetzung einen wichtigen Einfluss darstellt. Demgegenüber nehmen Herden mit Jungtieren nicht an Größe zu, was den Schluss zulässt, dass bei den Giraffen der Schutz des Nachwuchses vor Bejagung nicht über die Gruppengröße gesteuert wird. Einen weiteren wichtigen Faktor bei der Herdenbildung stellt die räumliche Verfügbarkeit von Nahrung dar. Dieser greift aber nicht über die Jahreszeiten hinweg, wodurch Herden als relativ stabil angesehen werden können. Fluktuationen in der Herdengröße sind demnach vom Nahrungsangebot abhängig und können über Tage deutlich schwanken. So kommt es häufig in den Morgen- und Abendstunden zu größeren Zusammenschlüssen, die der gemeinsamen Nahrungsaufnahme dienen.
Treffen zwei Bullen aufeinander, kommt es meistens zu einem ritualisierten Kampf, bei dem die Tiere nebeneinander stehen und ihren Kopf gegen den Hals des Konkurrenten schlagen. Zur Paarungszeit können solche Kämpfe aggressiver ausfallen und eine Heftigkeit annehmen, bei der einer der Konkurrenten bewusstlos geschlagen wird.
Entgegen weit verbreiteter Meinung fressen Giraffen, vor allem in der Trockenzeit, von niedrigen Büschen bzw. auf halber Körperhöhe.

Ein Argument, das gegen die Nahrungsaufnahme-Theorie spricht, ist, dass Giraffen im Laufe der Evolution stärker ihren Hals verlängert haben als ihre Beine. Längere Beine wären jedoch energetisch günstiger, wenn es nur um Höhengewinn gehen würde. Eine aktuelle Theorie für den langen Hals sieht daher den Kampf der Giraffen-Männchen um Dominanz und Weibchen als einen Hauptgrund. Ein langer Hals ist dabei im Kampf vorteilhaft.
Giraffen schlafen mehrmals innerhalb eines 24-Stunden-Tages, dabei liegen sie mit angezogenen Beinen auf dem Bauch, mit dem Kopf nach hinten auf dem Körper. Der Schlaf dauert in der Regel nur kurze Zeit, in mehr als der Hälfte aller Beobachtungen weniger als 11 Minuten, im Maximum bis zu 100 Minuten. Die REM-Phase währt im Mittel 3 Minuten. Es wird angenommen, dass die Tiere in der liegenden Stellung Raubtieren schutzlos ausgeliefert sind, da sie nur langsam aufstehen können und sich durch Treten mit den Beinen verteidigen. Den größten Teil der Nacht verbringen sie mit Wiederkäuen. Tagsüber dösen Giraffen hin und wieder kurz im Stehen, was insgesamt weniger als 50 Minuten eines 24-Stunden-Tages ausmacht.

It is classified by the International Union for Conservation of Nature as Vulnerable to extinction, and has been extirpated from many parts of its former range. The UN backed Convention of Migratory Species selected giraffes for protection in 2017. Giraffes are still found in numerous national parks and game reserves but estimations as of 2016 indicate that there are approximately 97,500 members of Giraffa in the wild, with around 1,144 in captivity.
The name "giraffe" has its earliest known origins in the Arabic word zarafah (?????), perhaps borrowed from the animal's Somali name geri. The Arab name is translated as "fast-walker". There were several Middle English spellings, such as jarraf, ziraph, and gerfauntz. The Italian form giraffa arose in the 1590s. The modern English form developed around 1600 from the French girafe.

The average weight is 1,192 kg (2,628 lb) for an adult male and 828 kg (1,825 lb) for an adult female with maximum weights of 1,930 kg (4,250 lb) and 1,180 kg (2,600 lb) having been recorded for males and females, respectively.

Male giraffes become darker as they age. The coat pattern has been claimed to serve as camouflage in the light and shade patterns of savannah woodlands. While adult giraffes standing among trees and bushes are hard to see at even a few metres' distance, they actively move into the open to gain the best view of an approaching predator, obviating any benefit that camouflage might bring. Instead, the adults rely on their size and ability to defend themselves. However, camouflage appears to be important for calves, which spend a large part of the day in hiding, away from their mothers; further, over half of all calves die within a year, so predation is certainly important. It appears, therefore, that the spotted coat of the giraffe functions as camouflage for the young, while adults simply inherit this coloration as a by-product. The skin underneath the dark areas may serve as windows for thermoregulation, being sites for complex blood vessel systems and large sweat glands. Each individual giraffe has a unique coat pattern.
The skin of a giraffe is mostly grey. Its thickness allows the animal to run through thorn bush without being punctured. The fur may serve as a chemical defence, as its parasite repellents give the animal a characteristic scent. At least 11 main aromatic chemicals are in the fur, although indole and 3-methylindole are responsible for most of the smell. Because the males have a stronger odour than the females, the odour may also have sexual function. Along the animal's neck is a mane made of short, erect hairs. The one-metre (3.3-ft) tail ends in a long, dark tuft of hair and is used as a defence against insects.
Giraffe gestation lasts 400-460 days, after which a single calf is normally born, although twins occur on rare occasions. The mother gives birth standing up. The calf emerges head and front legs first, having broken through the fetal membranes, and falls to the ground, severing the umbilical cord. The mother then grooms the new-born and helps it stand up. A new-born giraffe is 1.7-2 m (5.6-6.6 ft) tall. Within a few hours of birth, the calf can run around and is almost indistinguishable from a one-week-old. However, for the first 1-3 weeks, it spends most of its time hiding; its coat pattern providing camouflage. The ossicones, which have lain flat while it was in the womb, become erect within a few days.

The Mount Elliott Mining Complex is an aggregation of the remnants of copper mining and smelting operations from the early 20th century and the associated former mining township of Selwyn. The earliest copper mining at Mount Elliott was in 1906 with smelting operations commencing shortly after. Significant upgrades to the mining and smelting operations occurred under the management of W.R. Corbould during 1909 - 1910. Following these upgrades and increases in production, the Selwyn Township grew quickly and had 1500 residents by 1918. The Mount Elliott Company took over other companies on the Cloncurry field in the 1920s, including the Mount Cuthbert and Kuridala smelters. Mount Elliott operations were taken over by Mount Isa Mines in 1943 to ensure the supply of copper during World War Two. The Mount Elliott Company was eventually liquidated in 1953.
The Mount Elliott Smelter:
The existence of copper in the Leichhardt River area of north western Queensland had been known since Ernest Henry discovered the Great Australia Mine in 1867 at Cloncurry. In 1899 James Elliott discovered copper on the conical hill that became Mount Elliott, but having no capital to develop the mine, he sold an interest to James Morphett, a pastoralist of Fort Constantine station near Cloncurry. Morphett, being drought stricken, in turn sold out to John Moffat of Irvinebank, the most successful mining promoter in Queensland at the time.
Plentiful capital and cheap transport were prerequisites for developing the Cloncurry field, which had stagnated for forty years. Without capital it was impossible to explore and prove ore-bodies; without proof of large reserves of wealth it was futile to build a railway; and without a railway it was hazardous to invest capital in finding large reserves of ore. The mining investor or the railway builder had to break the impasse.
In 1906 - 1907 copper averaged £87 a ton on the London market, the highest price for thirty years, and the Cloncurry field grew. The railway was extended west of Richmond in 1905 - 1906 by the Government and mines were floated on the Melbourne Stock Exchange. At Mount Elliott a prospecting shaft had been sunk and on the 1st of August 1906 a Cornish boiler and winding plant were installed on the site.
Mount Elliott Limited was floated in Melbourne on the 13th of July 1906. In 1907 it was taken over by British and French interests and restructured. Combining with its competitor, Hampden Cloncurry Copper Mines Limited, Mount Elliott formed a special company to finance and construct the railway from Cloncurry to Malbon, Kuridala (then Friezeland) and Mount Elliott (later Selwyn). This new company then entered into an agreement with the Queensland Railways Department in July 1908.
The railway, which was known as the 'Syndicate Railway', aroused opposition in 1908 from the trade unions and Labor movement generally, who contended that railways should be State-owned. However, the Hampden-Mount Elliott Railway Bill was passed by the Queensland Parliament and assented to on the 21st of April 1908; construction finished in December 1910. The railway terminated at the Mount Elliott smelter.
By 1907 the main underlie shaft had been sunk and construction of the smelters was underway using a second-hand water-jacket blast furnace and converters. At this time, W.H. Corbould was appointed general manager of Mount Elliott Limited.
The second-hand blast furnace and converters were commissioned or 'blown in' in May 1909, but were problematic causing hold-ups. Corbould referred to the equipment in use as being the 'worst collection of worn-out junk he had ever come across'. Corbould soon convinced his directors to scrap the plant and let him design new works.
Corbould was a metallurgist and geologist as well as mine/smelter manager. He foresaw a need to obtain control and thereby ensure a reliable supply of ore from a cross-section of mines in the region. He also saw a need to implement an effective strategy to manage the economies of smelting low-grade ore. Smelting operations in the region were made difficult by the technical and economic problems posed by the deterioration in the grade of ore. Corbould resolved the issue by a process of blending ores with different chemical properties, increasing the throughput capacity of the smelter and by championing the unification of smelting operations in the region. In 1912, Corbould acquired Hampden Consols Mine at Kuridala for Mount Elliott Limited, followed with the purchases of other small mines in the district.
Walkers Limited of Maryborough was commissioned to manufacture a new 200 ton water jacket furnace for the smelters. An air compressor and blower for the smelters were constructed in the powerhouse and an electric motor and dynamo provided power for the crane and lighting for the smelter and mine.
The new smelter was blown in September 1910, a month after the first train arrived, and it ran well, producing 2040 tons of blister copper by the end of the year. The new smelting plant made it possible to cope with low-grade sulphide ores at Mount Elliott. The use of 1000 tons of low-grade sulphide ores bought from the Hampden Consols Mine in 1911 made it clear that if a supply of higher sulphur ore could be obtained and blended, performance, and economy would improve. Accordingly, the company bought a number of smaller mines in the district in 1912.
Corbould mined with cut and fill stoping but a young Mines Inspector condemned the system, ordered it dismantled and replaced with square set timbering. In 1911, after gradual movement in stopes on the No. 3 level, the smelter was closed for two months. Nevertheless, 5447 tons of blister copper was produced in 1911, rising to 6690 tons in 1912 - the company's best year. Many of the surviving structures at the site were built at this time.
Troubles for Mount Elliott started in 1913. In February, a fire at the Consols Mine closed it for months. In June, a thirteen week strike closed the whole operation, severely depleting the workforce. The year 1913 was also bad for industrial accidents in the area, possibly due to inexperienced people replacing the strikers. Nevertheless, the company paid generous dividends that year.
At the end of 1914 smelting ceased for more than a year due to shortage of ore. Although 3200 tons of blister copper was produced in 1913, production fell to 1840 tons in 1914 and the workforce dwindled to only 40 men. For the second half of 1915 and early 1916 the smelter treated ore railed south from Mount Cuthbert. At the end of July 1916 the smelting plant at Selwyn was dismantled except for the flue chambers and stacks. A new furnace with a capacity of 500 tons per day was built, a large amount of second-hand equipment was obtained and the converters were increased in size.
After the enlarged furnace was commissioned in June 1917, continuing industrial unrest retarded production which amounted to only 1000 tons of copper that year. The point of contention was the efficiency of the new smelter which processed twice as much ore while employing fewer men. The company decided to close down the smelter in October and reduce the size of the furnace, the largest in Australia, from 6.5m to 5.5m. In the meantime the price of copper had almost doubled from 1916 due to wartime consumption of munitions.
The new furnace commenced on the 16th of January 1918 and 77,482 tons of ore were smelted yielding 3580 tons of blister copper which were sent to the Bowen refinery before export to Britain. Local coal and coke supply was a problem and materials were being sourced from the distant Bowen Colliery. The smelter had a good run for almost a year except for a strike in July and another in December, which caused Corbould to close down the plant until New Year. In 1919, following relaxation of wartime controls by the British Metal Corporation, the copper price plunged from about £110 per ton at the start of the year to £75 per ton in April, dashing the company's optimism regarding treatment of low grade ores. The smelter finally closed after two months operation and most employees were laid off.
For much of the period 1919 to 1922, Corbould was in England trying to raise capital to reorganise the company's operations but he failed and resigned from the company in 1922. The Mount Elliott Company took over the assets of the other companies on the Cloncurry field in the 1920s - Mount Cuthbert in 1925 and Kuridala in 1926. Mount Isa Mines bought the Mount Elliott plant and machinery, including the three smelters, in 1943 for £2,300, enabling them to start copper production in the middle of the Second World War. The Mount Elliott Company was finally liquidated in 1953.
In 1950 A.E. Powell took up the Mount Elliott Reward Claim at Selwyn and worked close to the old smelter buildings. An open cut mine commenced at Starra, south of Mount Elliott and Selwyn, in 1988 and is Australia's third largest copper producer producing copper-gold concentrates from flotation and gold bullion from carbon-in-leach processing.
Profitable copper-gold ore bodies were recently proved at depth beneath the Mount Elliott smelter and old underground workings by Cyprus Gold Australia Pty Ltd. These deposits were subsequently acquired by Arimco Mining Pty Ltd for underground development which commenced in July 1993. A decline tunnel portal, ore and overburden dumps now occupy a large area of the Maggie Creek valley south-west of the smelter which was formerly the site of early miner's camps.
The Old Selwyn Township:
In 1907, the first hotel, run by H. Williams, was opened at the site. The township was surveyed later, around 1910, by the Mines Department. The town was to be situated north of the mine and smelter operations adjacent the railway, about 1.5km distant. It took its name from the nearby Selwyn Ranges which were named, during Burke's expedition, after the Victorian Government Geologist, A.R. Selwyn. The town has also been known by the name of Mount Elliott, after the nearby mines and smelter.
Many of the residents either worked at the Mount Elliott Mine and Smelter or worked in the service industries which grew around the mining and smelting operations. Little documentation exists about the everyday life of the town's residents. Surrounding sheep and cattle stations, however, meant that meat was available cheaply and vegetables grown in the area were delivered to the township by horse and cart. Imported commodities were, however, expensive.
By 1910 the town had four hotels. There was also an aerated water manufacturer, three stores, four fruiterers, a butcher, baker, saddler, garage, police, hospital, banks, post office (officially from 1906 to 1928, then unofficially until 1975) and a railway station. There was even an orchestra of ten players in 1912. The population of Selwyn rose from 1000 in 1911 to 1500 in 1918, before gradually declining.

While doing a short day trip for Salamanders in the Sierra Nevada Mountains, attempting to avoid the deer hunters during the last opening weekend, I came across massive quantities of wintering aggregation, while I have seen this phenomenon before I had not observed so many different groups before.

2012. Fir Island. Snow Geese by the thousands start arriving from the Arctic in early October. Typically 70,000 to 90,000 winter in North Puget Sound until late March or April.
Fraser-Skagit Population Dynamic: "Snow geese that over-winter in northwest Washington comprise a unique population of intercontinental travelers shared by three countries: the United States, Canada and Russia. These snow geese make an arduous, annual flight to Russia’s Chuckchi Sea, to breed on Wrangel Island off the north coast of Siberia. They are called the Fraser-Skagit population, because the same identification collaring/banding studies that disclosed details of their migration timing and itinerary, found that snow geese of this group had a high fidelity to one nesting site on Wrangel Island and to one wintering area, here. They stay apart from the other snow geese aggregations that nest separately on Wrangel and winter in California." wdfw.wa.gov
