Drum and Outer Dome of Maryland State House from Southeast by Alec Frazier

The Dome

Facts About the Dome

•Height, from base to weather vane: 121'

•Diameter at base: 40'

•Construction begun: 1785

•Interior work completed: 1797

•Wood used in dome construction: Timber from Maryland’s Eastern Shore, supplied by Dashiell family of Cypress Swamp, Somerset County.

•Architect of the dome: Joseph Clark

•Possible model for design of the dome: Schloßturm, the dome of the free-standing tower next to the palace of Karl-Wilhelm, Markgraf of Baden, in Karlsruhe, Germany

History of the State House Dome

When the Continental Congress came to Annapolis to meet in the Old Senate Chamber from November 1783 – August 1784, they found a State House which was still unfinished. Although the Old Senate Chamber was complete, the roof was not and it had leaked during the last few winters, damaging the upstairs rooms. The dome—or cupola—atop the State House was variously described as inadequate, unimpressive, and too small for the building and, it, too, leaked.

In order to rectify the situation, Joseph Clark, an Annapolis architect and builder, was asked to repair the roof and the dome. Clark first raised the pitch of the roof to facilitate the runoff of water and covered it with cypress shingles. The crowning achievement of Clark’s work on the State House was, of course, the extraordinary dome which he designed and built. It is not known where Clark’s inspiration for the unusual design of the dome came from, but it is very similar to one in Karlsruhe, Germany called the Schloßturm.

By the summer of 1788, the exterior of the new dome was complete. It was constructed of timber and no metal nails were used in its construction and, to this day, it is held together by wooden pegs reinforced by iron straps forged by an Annapolis ironmonger.

Although the exterior of the dome was completed by 1788, the interior was not completed until 1797. Tragedy struck the project in 1793 when a plasterer named Thomas Dance fell to his death from the inside of the dome. By 1794, Joseph Clark was completely disillusioned with the project and left it to John Shaw, the noted Annapolis cabinetmaker, to oversee completion. Over the years, John Shaw did much of the maintenance work on the State House, built various items for it and, in 1797, made the desks and chairs which furnished the Old Senate Chamber.

The First Dome: 1769-1774

Just as the Articles of Confederation did not effectively govern the country, the first dome of the State House at Annapolis did not survive more than a decade of Maryland weather. In 1769, the General Assembly of Maryland passed an act to erect a new state house, securely covered with slate tile or lead. The architect was Joseph Horatio Anderson, and the undertaker or builder of the project was Charles Wallace. According to William Eddis in 1773, the work was carried on with great dispatch and when completed would “be equal to any public edifice on the American continent.”

The exact date of the completion of the first dome or cupola is not known but evidence suggests that it was completed by the year 1774. In a 1773 Act of Assembly, Charles Wallace was instructed to fix an iron rod pointed with silver or gold at least six feet above the cupola. The General Assembly also recommended that the roof be covered with copper because the slate originally specified would require frequent repairs and cause other inconveniences. According to Charles E. Peterson’s “Notes on Copper Roofing in America to 1802”, it was more than likely that local copper was put on the roof to advertise the new industry of Maryland.

The Second Dome: 1785-1794

According to the Intendent of Revenue, Daniel St. Thomas Jenifer, the first dome of the State House was a contradiction of architectural design. A survey of the timbers in 1784 revealed that they were so decayed by water damage that a new dome would be required.

“It was originally constructed contrary to all rules of architecture; it ought to have been built double instead of single, and a staircase between the two domes, leading up to the lanthorn. The water should have been carried off by eaves, instead of being drawn to the center of the building, to two small conductors, which are liableto be choked by ice, and overflowed by rains. That it was next to impossible, under present construction, that it could have been made tight”.

On February 24, 1785 Jenifer placed a notice in the Maryland Gazette for carpenters work to be made to the dome and roof under the execution of Joseph Clark

“The work We are a Doing is to put a Roof on the Governor’s House and we are going to take the Roof of the State house and it is a going to Raise it one story higher and the Doom is to be Sixty foot higher then the old one”.

Clark raised the pitch of the dome to facilitate the runoff of excess water, the chief reason the timbers rotted in the original dome.

“The Annapolis dome is in its proportions like the original Karlsruhe tower. Possibly its more classical feeling is a result of the universal trend of architectural styles rather than the influence of the altered Schloßturm. Yet the arched windows below the architrave in Annapolis, one with the lower part closed, are like the windows below the Architrave in Karlsruhe in all of which the lower parts are closed. The horizontal oval windows below the main curving section of the dome in Annapolis resemble the vertical ovals in the equivalent part of the Karlsruhe tower. The small square windows above the balustrades and the architraves themselves in both buildings are similarly placed.”

Bay de Noquet Lumber Company Waster Burner_Nahma_Delta (1) by Michigan State Historic Preservation Office

The Bay de Noquet Lumber Company Waste Burner is a

cylindrical brick-lined iron structure about one hundred feet tall and thirty-two feet in diameter between the outer walls. Constructed between 1888 and 1893, the structure was built to burn bark and other waste products from the company’s nearby sawmill. Standing on a limestone base, the burner is faced in plates supported by five broad horizontal metal bands or straps in the lower portion and four more horizontal

cylindrical metal bands toward the top. Brick wall

s line the lower part of the interior. In the lower thirty feet the brick lining is one and one-half feet in thickness, in the twenty-four feet above that the lining is one brick or a bout eight inches in thickness. Above the fifty-four-foot level the burner has no lining. A hemispherical metal mesh screen, topped by a

weather vane bearing the initials of the Bay de Noquet Company – B. De. N. Co. – caps the burner.

Constructed between 1889 and 1893, the Bay de Noque

t Company structure is the last of the many of its

late nineteenth-century generation of wood waste burners associated with sawmill and wood products operations known to

survive in Michigan. The burner is the only remnant left of the Bay de Noquet Company sawmill operation that gave rise to the

company town of Nahma in the early 1880s and served

as the village’s economic mainstay until 1951, whe

n the mills closed down.

The Bay de Noquet Lumber Company Waste Burner was listed in the National Register of Historic Places on April 8, 2011.

See-Through Reflecting Telescope / L'intérieur d'un télescope by Michel Labrecque

(le français suit l'anglais)

See-Through Reflecting Telescope

Type: Schmidt-Cassegrain reflecting telescope

Manufaturer: Celestron

Diameter: 203 mm (8 inches)

Focal length: 2000 mm

Focal ratio: f/10

The "Hidden Worlds" exhibition in the new Canada Science and Technology Museum features a see-through reflecting telescope which visitors can look through.

The optical design of this telescope (catadioptric) uses a combination of a lens, called the corrector (at the front), and mirrors to collect and focus light from a distant star.

The primary mirror visible at the base of the acrylic tube reflects light to the secondary mirror which is mounted on the underside of the corrector lens (the black circle), and then through a hole in the primary mirror to the point of focus, where the image is magnified by the eyepiece for your eye to see.

In this optical design, the light path is reflected back and forth, and folded onto itself to produce a very compact and portable telescope.

Les mondes cachés, une exposition dans le nouveau Musée des sciences et de la technologie du Canada met en vedette ce télescope que les visiteurs peuvent voir à travers.

Le design optique du télescope (dit catadioptrique) utilise une combinaison d'une lentille, appelée le correcteur (à l'avant), et des miroirs pour collecter et focaliser la lumière d'une étoile lointaine.

Le miroir primaire, visible à la base du tube acrylique réfléchit la lumière vers le miroir secondaire qui est monté sur le dessous de la lentille correctrice (le cercle noir), puis à travers un trou dans le miroir primaire jusqu'au point de focalisation, où l'image est agrandie par l'oculaire pour être vu par l'oeil.

The bud in the sunlight is about 1/32" in diameter!

.

The photographs in my set, "Weed Flower Micros," may appear to be close-ups of regular-sized flowers – they are not!

These are micro (macro) photos of tiny little flowers which bloom on ordinary weeds.

How tiny? The largest weed flower in the set is only, when measured across its widest part from petal tip to petal tip, 3/4" in diameter!

Some of these miniscule flowers are so small that the entire blossom you are looking at is 1/4" in diameter…again that’s measuring from petal tip to petal tip across the widest part of the bloom!

The smallest part of a weed flower that I have managed to successfully shoot and achieve good detail in is a photo I made of a bud that measured LESS than 1/16" in diameter across its widest part! For a reference to its size I have also included a photo of that bud next to the head of an ordinary paper match, which dwarfs the bud.

I am delighting in discovering the beauty, complexity, and variety in something so small that it’s easily ignored or downright difficult to see with the naked eye.

And it’s an even greater delight to realize that this incredible beauty has been growing wild in my lawn, year after year, right under my un-seeing eyes as I’ve repeatedly mown them down with my lawn mower, never realizing the unseen beauty that I was trampling under my feet.

I hope you enjoy viewing these as much as I do. I have a lot of fun making them for us to look at!

Monteath Mausoleum - Glasgow Necropolis by Bolckow

"This wonderful Mausoleum is the final resting place of two brothers Major Archibald Douglas Monteath who died in 1842, and James Monteath Douglas who died in 1850. The Mausoleum, which was designed by David Cousin, is 30ft in diameter. What makes the Mausoleum so special includes the faces of 48 individual Dwar Palas who guard the Mausoleum, and which are common in Indian and Hindu temples, palaces and forts. The connection with India was because Major Monteath was an Officer with the East India Company. Monteath Mausoleum: History and Description by Lynda Henderson as part of her Architecture Conservation course

This mausoleum was built for Major Archibald Douglas Monteath, who served in the East

India Company before returning to Glasgow. He was interred here in 1842 and his brother, James Monteath Douglas, was interred here in 1850.

Monteath Mausoleum

An entertaining story – its truthfulness debatable – is that while serving in India, Monteath “made his fortune when an elephant carrying precious gems belonging to a Maharajah was captured and ‘relieved’ of its load by him.”

The mausoleum was designed by architect David Cousin, who is best known for his Edinburgh work. It is an unusual building, being of neo-Norman design in this cemetery of predominantly classical monuments. Intriguingly it has no writing, lettering or numerals inscribed anywhere on it – it is completely silent about its occupants.

It is a circular temple building 30 ft in diameter, the design of which was based on the Knights Templar Church of the Holy Sepulchre 8. The main lower portion of the building is split into sixteen facets around its circumference with one double-bay-wide entrance arch and fourteen deep, round-arched blank window niches at low level, each one elaborately carved in a different design. Above these are recessed panels with four columns topped by semi-circular interweaved arches. Above this a cornice supports the edge of the lower roof – a shallow conical roof of large stone slabs, each slab alternately higher and lower around the roof. Over this sits a lantern with eight facets, each facet having three slit openings flanked by columns topped with arches. Above these are regularly spaced grotesque faces which support the cornice and roof of the lantern – again stone but in a common tile pattern. This is topped with a mini version of the Choragic Monument of Lysicrates.

The entrance porch is elaborately carved with a round arch over the door including carved grotesque faces and a pitched stone roof above. The door is solid timber, secured with two padlocks. I was unable to gain access to the interior of the mausoleum as the Council have lost the keys, however Ruth Johnston notes in her book “Afterlives Tales Of Interments” that “internally the monument is unfinished rubble work walls and the roof of the tower inside is brick.” This based on the description in George Blair’s ‘Sketches of Glasgow Necropolis’.

A building in Edinburgh on Rutland Place by David Cousin sports an identical entrance porch – every detail is the same!

Nearly every surface of this building is decorated with carving, much of it high relief and intricate."

Series Filters, May 43 PopPho pg. 81 by Camera Wiki

Filters advertised in 1940 issues of Popular Photography were often in the form of unthreaded disks fitted into adapters sized to fit various lens diameters (see here and here). But these were not yet referred to as Series filters.

Here in 1943 we have a reference to "Series VI" and "Series V" as a "famous Eastman" standard. I am still missing an exact reference to when this standard emerged; but it seems to have been something fairly recent at this time.
