Fangruida: human landing on Mars 10 cutting-edge technology

[Fangruida- human landing on Mars 10 innovative and sophisticated technologies]

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

-------------------------------------------------- -------------

Aerospace Science Space Science and Technology on behalf of the world's most cutting-edge leader in high technology, materials, mechatronics, information and communication, energy, biomedical, marine, aviation aerospace, microelectronics, computer, automation, intelligent biochips, use of nuclear energy, light mechanical and electrical integration, astrophysics, celestial chemistry, astrophysics and so a series of geological science and technology. Especially after the moon landing, the further development of mankind to Mars and other planets into the powerful offensive, the world's major powers eager to Daxian hand of God, increase investment, vigorously develop new sophisticated technology projects for space to space. Satellite, space station, the new spacecraft, the new space suits, the new radiation protection materials, intelligent materials, new manufacturing technology, communications technology, computer technology, detector technology, rover, rover technology, biomedical technology, and so one after another, is expected to greater breakthroughs and leaps. For example, rocket technology, spacecraft design, large power spacecraft, spacesuits design improvements, radiation multifunctional composite materials, life health care technology and space medicine, prevention against microgravity microgravity applicable drugs, tracking control technology, landing and return technology. Mars lander and returned safely to Earth as a top priority. Secondly, Mars, the Moon base and the use of transforming Mars, the Moon and other development will follow. Whether the former or the latter, are the modern aerospace science, space science basic research, applied basic research and applied research in the major cutting-edge technology. These major cutting-edge technology research and innovation, not only for human landing on Mars and the safe return of great significance, but for the entire space science, impact immeasurable universe sciences, earth sciences and human life. Here the most critical of the most important research projects of several sophisticated technology research and development as well as its core technology brief. Limit non-scientific techniques include non-technical limits of technology, the key lies in technology research and development of technology maturity, advanced technology, innovative, practical, reliable, practical application, business value and investment costs, and not simply like the idea mature technology achievements, difficult to put into things. This is the high-tech research and development, testing, prototype, test application testing, until the outcome of industrialization. Especially in aerospace technology, advanced, novelty, practicality, reliability, economy, maturity, commercial value and so on. For technical and research purely science fiction and the like may be irrelevant depth, but not as aerospace engineering and technology practice. Otherwise, Mars will become a dream fantasy, and even into settling crashed out of danger.

Regardless of the moon or Mars, many technical difficulties, especially a human landing on Mars and return safely to Earth, technical difficulties mainly in the following aspects. (Transformation of Mars and the Moon and other planets and detect other livable technology more complex and difficult, at this stage it is difficult to achieve and therefore not discussed in detail in this study). In fact, Mars will be the safe return of a full set of technology, space science, aerospace crucial scientific research development, its significance is not confined to Mars simply a return to scientific value, great commercial value, can not be measure.

1. Powered rocket, the spacecraft overall structural design not be too complex large, otherwise, the safety factor to reduce the risk of failure accidents. Fusion rocket engine main problem to be solved is the high-temperature materials and fuel ignition chamber (reaction chamber temperatures of up to tens of millions of supreme billion degrees), fissile class rocket engine whose essence is the miniaturization of nuclear reactors, and placed on the rocket. Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues unresolved. Electrothermal rocket engine utilizing heat energy (resistance heating or electric arc heating) working medium (hydrogen, amines, hydrazine ), vaporized; nozzle expansion accelerated after discharged from the spout to generate thrust. Static rocket engine working fluid (mercury, cesium, hydrogen, etc.) from the tank enter the ionization chamber is formed thrust ionized into a plasma jet. Electric rocket engines with a high specific impulse (700-2500 sec), extremely long life (can be repeated thousands of times a starter, a total of up to thousands of hours of work). But the thrust of less than 100N. This engine is only available for spacecraft attitude control, station-keeping and the like. One nuclear - power rocket design is as follows: Firstly, the reactor heats water to make it into steam, and then the high-speed steam ejected, push the rocket. Nuclear rocket using hydrogen as working substance may be a better solution, it is one of the most commonly used liquid hydrogen rocket fuel rocket carrying liquid hydrogen virtually no technical difficulties. Heating hydrogen nuclear reactor, as long as it eventually reaches or exceeds current jet velocity hydrogen rocket engine jet speed, the same weight of the rocket will be able to work longer, it can accelerate the Rockets faster. Here there are only two problems: First, the final weight includes the weight of the rocket in nuclear reactors, so it must be as light as possible. Ultra-small nuclear reactor has been able to achieve. Furthermore, if used in outer space, we can not consider the problem of radioactive residues, simply to just one proton hydrogen nuclei are less likely to produce induced radioactivity, thus shielding layer can be made thinner, injected hydrogen gas can flow directly through the reactor core, it is not easy to solve, and that is how to get back at high speed heated gas is ejected.

Rocket engine with a nuclear fission reactor, based on the heating liquid hydrogen propellant, rather than igniting flammable propellant

High-speed heavy rocket is a major cutting-edge technology. After all, space flight and aircraft carriers, submarines, nuclear reactors differ greatly from the one hand, the use of traditional fuels, on the one hand can be nuclear reactor technology. From the control, for security reasons, the use of nuclear power rocket technology, safe and reliable overriding indicators. Nuclear atomic energy in line with the norms and rules of outer space. For the immature fetal abdominal hatchery technology, and resolutely reject use. This is the most significant development of nuclear-powered rocket principle.

Nuclear-powered spaceship for Use of nuclear power are three kinds:

The first method: no water or air space such media can not be used propeller must use jet approach. Reactor nuclear fission or fusion to produce a lot of heat, we will propellant (such as liquid hydrogen) injection, the rapid expansion of the propellant will be heated and then discharged from the engine speed tail thrust. This method is most readily available.

The second method: nuclear reactor will have a lot of fast-moving ions, these energetic particles moving very fast, so you can use a magnetic field to control their ejection direction. This principle ion rocket similar to the tail of the rocket ejected from the high-speed mobile ions, so that the recoil movement of a rocket. The advantage of this approach is to promote the unusually large ratio, without carrying any medium, continued strong. Ion engine, which is commonly referred to as "electric rocket", the principle is not complicated, the propellant is ionized particles,

Plasma Engine

Electromagnetic acceleration, high-speed spray. From the development trend, the US research scope covers almost all types of electric thrusters, but mainly to the development of ion engines, NASA in which to play the most active intake technology and preparedness plans. "

The third method: the use of nuclear explosions. It is a bold and crazy way, no longer is the use of a controlled nuclear reaction, but to use nuclear explosions to drive the ship, this is not an engine, and it is called a nuclear pulse rocket. This spacecraft will carry a lot of low-yield atomic bombs out one behind, and then detonated, followed by a spacecraft propulsion installation disk, absorbing the blast pushing the spacecraft forward. This was in 1955 to Orion (Project Orion) name of the project, originally planned to bring two thousand atomic bombs, Orion later fetal nuclear thermal rocket. Its principle is mounted on a small rocket reactor, the reactor utilizing thermal energy generated by the propellant is heated to a high temperature, high pressure and high temperature of the propellant from the high-speed spray nozzle, a tremendous impetus.

Common nuclear fission technologies, including nuclear pulse rocket engines, nuclear rockets, nuclear thermal rocket and nuclear stamping rockets to nuclear thermal rocket, for example, the size of its land-based nuclear power plant reactor structure than the much smaller, more uranium-235 purity requirements high, reaching more than 90%, at the request of the high specific impulse engine core temperature will reach about 3000K, require excellent high temperature properties of materials.

Research and test new IT technologies and new products and new technology and new materials, new equipment, things are difficult, design is the most important part, especially in the overall design, technical solutions, technical route, technical process, technical and economic particularly significant. The overall design is defective, technology there are loopholes in the program, will be a major technical route deviation, but also directly related to the success of research trials. so, any time, under any circumstances, a good grasp of the overall control of design, technical design, is essential. otherwise, a done deal, it is difficult save. aerospace technology research and product development is true.

3, high-performance nuclear rocket

Nuclear rocket nuclear fission and fusion energy can rocket rocket two categories. Nuclear fission and fusion produce heat, radiation and shock waves and other large amounts of energy, but here they are contemplated for use as a thermal energy rocket.

Uranium and other heavy elements, under certain conditions, will split their nuclei, called nuclear fission reaction. The atomic bomb is the result of nuclear fission reactions. Nuclear fission reaction to release energy, is a million times more chemical rocket propellant combustion energy. Therefore, nuclear fission energy is a high-performance rocket rockets. Since it requires much less propellant than chemical rockets can, so to its own weight is much lighter than chemical rockets energy. For the same quality of the rocket, the rocket payload of nuclear fission energy is much greater than the chemical energy of the rocket. Just nuclear fission energy rocket is still in the works. 

Use of nuclear fission energy as the energy of the rocket, called the atomic rockets. It is to make hydrogen or other inert gas working fluid through the reactor, the hydrogen after the heating temperature quickly rose to 2000 ℃, and then into the nozzle, high-speed spray to produce thrust. 

A vision plan is to use liquid hydrogen working fluid, in operation, the liquid hydrogen tank in the liquid hydrogen pump is withdrawn through the catheter and the engine cooling jacket and liquid hydrogen into hydrogen gas, hydrogen gas turbine-driven, locally expansion. Then by nuclear fission reactors, nuclear fission reactions absorb heat released, a sharp rise in temperature, and finally into the nozzle, the rapid expansion of high-speed spray. Calculations show that the amount of atomic payload rockets, rocket high chemical energy than 5-8 times.

Hydrogen and other light elements, under certain conditions, their nuclei convergent synthesis of new heavy nuclei, and release a lot of energy, called nuclear fusion reaction, also called thermonuclear reaction. 

Using energy generated by the fusion reaction for energy rocket, called fusion energy rocket or nuclear thermal rockets. But it is also not only take advantage of controlled nuclear fusion reaction to manufacture hydrogen bombs, rockets and controlled nuclear fusion reaction needs still studying it.

Of course there are various research and development of rocket technology and technical solutions to try.

It is envisaged that the rocket deuterium, an isotope of hydrogen with deuterium nuclear fusion reaction of helium nuclei, protons and neutrons, and release huge amounts of energy, just polymerized ionized helium to temperatures up to 100 million degrees the plasma, and then nozzle expansion, high-speed ejection, the exhaust speed of up to 15,000 km / sec, atomic energy is 1800 times the rocket, the rocket is the chemical energy of 3700 times.

Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. In a nuclear reactor, nuclear energy into heat to heat the working fluid, the working fluid is heated after expansion nozzle to accelerate to the speed of 6500 ~ 11,000 m / sec from the discharge orifice to produce thrust. Nuclear rocket engine specific impulse (250 to 1000 seconds) long life, but the technology is complex, apply only to long-term spacecraft. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues not resolved, is still in the midst of trials. Nuclear rocket technology is cutting-edge aerospace science technology, centralized many professional and technical sciences and aerospace, nuclear physics, nuclear chemistry, materials science, the long term future ___-- wide width. The United States, Russia and Europe, China, India, Japan, Britain, Brazil and other countries in this regard have studies, in particular the United States and Russia led the way, impressive. Of course, at this stage of nuclear rocket technology, technology development there are still many difficulties. Fully formed, still to be. But humanity marching to the universe, nuclear reactor applications is essential.

Mars oxygen necessary for survival but also from the decomposition of water, electrolytically separating water molecules of oxygen and hydrogen, this oxygen equipment has been successfully used in the International Space Station. Oxygen is released into the air to sustain life, the hydrogen system into the water system.

4. The issue of food waste recycling. At present, the International Space Station on the use of dehumidifiers, sucked moisture in the air to be purified, and then changed back to drinkable water. The astronauts' urine and sweat recycling. 5. water. The spacecraft and the space station on purification system also makes urine and other liquids can be purified utilization. 6. microgravity. In microgravity or weightlessness long-term space travel, if protective measures shall not be treated, the astronauts will be muscle atrophy, bone softening health. 7. contact. 8. Insulation, 9 energy. Any space exploration are inseparable from the energy battery is a new super hybrid energy storage device, the asymmetric lead-acid batteries and supercapacitors in the same compound within the system - and the so-called inside, no additional separate electronic control unit, this is an optimal combination. The traditional lead-acid battery PbO2 monomer is a positive electrode plate and a negative electrode plate spongy Pb composition, not a super cell. : Silicon solar cells, multi-compound thin film solar cells, multi-layer polymer-modified electrode solar cells, nano-crystalline solar cells, batteries and super class. For example, the solar aircraft .10. To protect the health and life safety and security systems. Lysophosphatidic acid LPA is a growth factor-like lipid mediators, the researchers found that this substance can on apoptosis after radiation injury and animal cells was inhibited. Stable lysophosphatidic acid analogs having the hematopoietic system and gastrointestinal tract caused by acute radiation sickness protection, knockout experiments show that lysophosphatidic acid receptors is an important foundation for the protection of radiation injury. In addition to work under high pressure, the astronauts face a number of health threats, including motion sickness, bacterial infections, blindness space, as well as psychological problems, including toxic dust. In the weightless environment of space, the astronaut's body will be like in preadolescents, as the emergence of various changes.

Plantar molt

After the environment to adapt to zero gravity, the astronaut's body will be some strange changes. Weightlessness cause fluid flow around the main flow torso and head, causing the astronauts facial swelling and inflammation, such as nasal congestion. During long-term stay in space

Bone and muscle loss

Most people weightlessness caused by the impact may be known bone and muscle degeneration. In addition, the calcium bones become very fragile and prone to fracture, which is why some of the astronauts after landing need on a stretcher.

Space Blindness

Space Blindness refers astronaut decreased vision.

Solar storms and radiation is one of the biggest challenges facing the long-term space flight. Since losing the protection of Earth's magnetic field, astronauts suffer far more than normal levels of radiation. The cumulative amount of radiation exposure in low earth orbit them exceeded by workers close to nuclear reactors, thereby increasing the risk of cancer.

Prolonged space flight can cause a series of psychological problems, including depression or mood swings, vulnerability, anxiety and fear, as well as other sequelae. We are familiar with the biology of the Earth, the Earth biochemistry, biophysics, after all, the Earth is very different astrophysics, celestial chemistry, biophysics and astrophysics, biochemistry and other celestial bodies. Therefore, you must be familiar with and adapt to these differences and changes.

Osteoporosis and its complications ranked first in the space of disease risk.

Long-term health risks associated with flying Topics

The degree of influence long-term biological effects of radiation in human flight can withstand the radiation and the maximum limit of accumulated radiation on physiology, pathology and genetics.

Physiological effects of weightlessness including: long-term bone loss and a return flight after the maximum extent and severity of the continued deterioration of other pathological problems induced by the; maximum flexibility and severity of possible long-term Flight Center in vascular function.

Long-term risk of disease due to the high risk of flight stress, microbial variation, decreased immune function, leading to infections

Radiation hazards and protection

However, space technology itself is integrated with the use of the most advanced technology, its challenging technical reserves and periodic demanding

With the continuous development of science and technology, space agencies plan a manned landing on the moon and Mars, space exploration emergency medicine current concern.

Space sickness

In the weightless environment of space, in the weightless environment of space, surgery may be extremely difficult and risky.

Robot surgeons

Space disease in three days after entering the space started to ease, although individual astronauts might subsequently relapse. January 2015 NASA declared working on a fast, anti-nausea and nasal sprays. In addition, due to the zero-gravity environment, and anti-nausea drugs can only be administered by injection or transdermal patches manner.

Manned spaceflight in the 21st century is the era of interplanetary flight, aerospace medicine is closely watched era is the era of China's manned space flourish. Only the central issue, and grasp the opportunity to open up a new world of human survival and development.

Various emergency contingency measures in special circumstances. Invisible accident risk prevention. Enhancing drugs and other screening methods immunity aerospace medicine and tissue engineering a microgravity environment. Drug mixture of APS, ginseng polysaccharides, Ganoderma lucidum polysaccharides, polysaccharides and Lentinan, from other compounds. Drug development space syndrome drug, chemical structure modification will be an important part.

These issues are very sensitive, cutting-edge technology is a major difficulty landing on Mars. Countries in the world, especially the world's major space powers in the country strategies and technical research, the results of all kinds continue to emerge. United States, Russia, China, Europe, India, Japan and other countries is different. United States, Russia extraordinary strength. Many patented technology and health, and most belong to the top-secret technology. Especially in aerospace engineering and technological achievements is different from the general scientific literature, practical, commercial, industrial great, especially the performance of patents, know-how, technical drawings, engineering design and other aspects. Present Mars and return safely to Earth, the first manned, significance, everything is hard in the beginning, especially the first person to land on Mars This Mars for Human Sciences Research Mars, the moon, the earth, the solar system and the universe, life and other significant. Its far greater than the value of direct investments and business interests.

In addition, it is the development of new materials, suitable for deep space operations universe, life, and other detection, wider field.

Many aerospace materials, continuous research and development of materials are key areas of aerospace development, including material rocket, the spacecraft materials, the suit materials, radiation materials, materials and equipment, instruments, materials and so on biochemistry.

Temperature metal-based compound with a metal matrix composite body with a more primordial higher temperature strength, creep resistance, impact resistance, thermal fatigue and other excellent high temperature performance.

In B, C, SiC fiber reinforced Ti3Al, TiAl, Ni3Al intermetallic matrix composites, etc.

W Fiber Reinforced with nickel-based, iron-based alloys as well as SiC, TiB2, Si3N4 and BN particle reinforced metal matrix composites

High temperature service conditions require the development of ceramic and carbon-based composite materials, etc., not in this eleven Cheung said.

Fuel storage

In order to survive in space, people need many things: food, oxygen, shelter, and, perhaps most importantly, fuel. The initial quality Mars mission somewhere around 80 percent of the space launch humans will be propellant. The fuel amount of storage space is very difficult.

This difference in low Earth orbit cause liquid hydrogen and liquid oxygen - rocket fuel - vaporization.

Hydrogen is particularly likely to leak out, resulting in a loss of about 4% per month.

When you want to get people to Mars speed to minimize exposure to weightlessness and space radiation hazards

Mars

Landings on the Martian surface, they realized that they reached the limit. The rapid expansion of the thin Martian atmosphere can not be very large parachute, such as those that will need to be large enough to slow down, carry human spacecraft.

Therefore, the parachute strong mass ratio, high temperature resistance, Bing shot performance and other aspects of textile materials used have special requirements, in order to make a parachute can be used in rockets, missiles, Yu arrows spacecraft and other spacecraft recovery, it is necessary to improve the canopy heat resistance, a high melting point polymeric fiber fabric used, the metal fabric, ceramic fiber fabrics, and other devices.

Super rigid parachute to help slow the landing vehicle.

Spacecraft entered the Martian atmosphere at 24,000 km / h. Even after slowing parachute or inflatable, it will be very

Once we have the protection of the Earth magnetic field, the solar radiation will accumulate in the body, a huge explosion threw the spacecraft may potentially lethal doses of radiation astronauts.

In addition to radiation, the biggest challenge is manned trip to Mars microgravity, as previously described.

The moon is sterile. Mars is another case entirely.

With dust treatment measures.

Arid Martian environment to create a super-tiny dust particles flying around the Earth for billions of years.

Apollo moon dust encountered. Ultra-sharp and abrasive lunar dust was named something that can clog the basic functions of mechanical damage. High chloride salt, which can cause thyroid problems in people.

Mars geological structure and geological structure of the moon, water on Mars geology, geology of the Moon is very important, because he, like the Earth's geology is related to many important issues. Water, the first element of life, air, temperature, and complex geological formations are geological structure. Cosmic geology research methods, mainly through a variety of detection equipment equipped with a space probe, celestial observations of atmospheric composition, composition and distribution of temperature, pressure, wind speed, vertical structure, composition of the solar wind, the water, the surface topography and Zoning, topsoil the composition and characteristics of the component surface of the rock, type and distribution, stratigraphic sequence, structural system and the internal shell structure.

Mars internal situation only rely on its surface condition of large amounts of data and related information inferred. It is generally believed that the core radius of 1700 km of high-density material composition; outsourcing a layer of lava, it is denser than the Earth's mantle some; outermost layer is a thin crust. Compared to other terrestrial planets, the lower the density of Mars, which indicates that the Martian core of iron (magnesium and iron sulfide) with may contain more sulfur. Like Mercury and the Moon, Mars and lack active plate movement; there is no indication that the crust of Mars occurred can cause translational events like the Earth like so many of folded mountains. Since there is no lateral movement in the earth's crust under the giant hot zone relative to the ground in a stationary state. Slight stress coupled with the ground, resulting in Tharis bumps and huge volcano. For the geological structure of Mars is very important, which is why repeated explorations and studies of Martian geological reasons.

The outermost layer of the crust.

Crustal thickness obtained, the original thickness of the low north 40 km south plateau 70 kilometers thick, an average of 50 kilometers, at least 80 km Tharsis plateau and the Antarctic Plateau, and in the impact basin is thin, as only about 10 kilometers Greece plains.

Canyon of Mars there are two categories: outflow channels (outflow channel) and tree valley (valley network). The former is very large, it can be 100 km wide, over 2000 km long, streamlined, mainly in the younger Northern Hemisphere, such as the plain around Tyre Chris Canyon and Canyon jam.

In addition, the volcanic activity sometimes lava formation lava channels (lava channel); crustal stress generated by fissures, faults, forming numerous parallel extending grooves (fossa), such as around the huge Tharsis volcanic plateau radially distributed numerous grooves, which can again lead to volcanic activity.

Presumably, Mars has an iron as the main component of the nucleus, and contains sulfur, magnesium and other light elements, the nuclear share of Mars, the Earth should be relatively small. The outer core is covered with a thick layer of magnesium-rich silicate mantle, the surface of rocky crust. The density of Earth-like planets Mars is the lowest, only 3.93g / cc.

Lunar core

The average density of the Moon is 3.3464 g / cc, the solar system satellites second highest (after Aiou). However, there are few clues mean lunar core is small, only about 350 km radius or less [2]. The core of the moon is only about 20% the size of the moon, the moon's interior has a solid, iron-rich core diameter of about 240 kilometers (150 miles); in addition there is a liquid core, mainly composed of iron outer core, about 330 km in diameter (205 miles), and for the first time compared with the core of the Earth, considered as the earth's outer core, like sulfur and oxygen may have lighter elements [4].

Chemical elements on the lunar surface constituted in accordance with its abundance as follows: oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminum (Al), manganese (Mn), titanium ( Ti). The most abundant is oxygen, silicon and iron. The oxygen content is estimated to be 42% (by weight). Carbon (C) and nitrogen (N) only traces seem to exist only in trace amounts deposited in the solar wind brings.

Moon geological history is an important event in recent global magma ocean crystallization. The specific depth is not clear, but some studies have shown that at least a depth of about 500 kilometers or more.

Lunar landscape

Lunar landscape can be described as impact craters and ejecta, some volcanoes, hills, lava-filled depressions.

Regolith

TABLE bear the asteroid and comets billions of years of bombardment. Over time, the impact of these processes have already broken into fine-grained surface rock debris, called regolith. Young mare area, regolith thickness of about 2 meters, while the oldest dated land, regolith thickness of up to 20 meters. Through the analysis of lunar soil components, in particular the isotopic composition changes can determine the period of solar activity. Solar wind gases possible future lunar base is useful because oxygen, hydrogen (water), carbon and nitrogen is not only essential to life, but also may be useful for fuel production. Lunar soil constituents may also be as a future source of energy.

Here, repeatedly stressed that the geological structure and geological structure of celestial bodies, the Earth, Moon, Mars, or that this human existence and development of biological life forms is very important, especially in a series of data Martian geological structure geological structure is directly related to human landing Mars and the successful transformation of Mars or not. for example, water, liquid water, water, oxygen, synthesis, must not be taken lightly.

Mars landing 10 Technology

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

[

"1" rocket propulsion technology ion fusion nuclear pulse propulsion rocket powered high-speed heavy rocket technology, space nuclear reactors spacecraft] brought big problems reflected in the nuclear reaction, nuclear radiation on spacecraft launch, control, brakes and other impact.

In particular, for the future of nuclear power spacecraft, the need to solve the nuclear reactor design, manufacture, control, cooling, radiation shielding, exhaust pollution, high thermoelectric conversion efficiency and a series of technical problems.

In particular, nuclear reactors produce radiation on astronauts' health will pose a great threat, which requires the spacecraft to be nuclear radiation shielding to ensure astronaut and ship the goods from radiation and heat from the reactor influence, but this will greatly increase the weight of the detector.

Space nuclear process applications, nuclear reaction decay is not a problem, but in a vacuum, ultra-low temperature environment, the nuclear reaction materials, energy transport materials have very high demands.

Space facing the reality of a nuclear reactor cooling cooling problems. To prevent problems with the reactor, "Washington" aircraft carrier to take four heavy protective measures for the radiation enclosed in the warship. These four measures are: the fuel itself, fuel storage pressure vessel, reactor shell and the hull. US Navy fuel all metal fuel, designed to take the impact resistance of the war, does not release fission product can withstand more than 50 times the gravity of the impact load; product of nuclear fission reactor fuel will never enter loop cooling water. The third layer of protection is specially designed and manufactured the reactor shell. The fourth layer is a very strong anti-impact combat ship, the reactor is arranged in the center of the ship, very safe. Engage in a reactor can only be loaded up to the aircraft, so as to drive the motor, and then drive the propeller. That is the core advantage of the heat generated by the heated gas flow, high temperature high pressure gas discharge backward, thereby generating thrust.

.

After installation AMPS1000 type nuclear power plant, a nuclear fuel assembly: He is a core member of the nuclear fuel chain reaction. Usually made into uranium dioxide, of which only a few percent uranium-235, and most of it is not directly involved in the nuclear fission of uranium 238. The uranium dioxide sintered into cylindrical pieces, into a stainless steel or a zirconium alloy do metal tubes called fuel rods or the original, then the number of fuel rods loaded metal cylinder in an orderly composition of the fuel assembly, and finally put a lot of vertical distribution of fuel assemblies in the reactor.

Nuclear reactor pressure vessel is a housing for containing nuclear fuel and reactor internals, for producing high-quality high-strength steel is made to withstand the pressure of dozens MPa. Import and export of the coolant in the pressure vessel.

The top of the pressure vessel closure, and can be used to accommodate the fixed control rod drive mechanism, pressure vessel head has a semi-circular, flat-topped.

Roof bolt: used to connect the locking pressure vessel head, so that the cylinder to form a completely sealed container.

Neutron Source: Plug in nuclear reactors can provide sufficient neutron, nuclear fuel ignition, to start to enhance the role of nuclear reactors and nuclear power. Neutron source generally composed of radium, polonium, beryllium, antimony production. Neutron source and neutron fission reactors are fast neutron, can not cause fission of uranium 235, in order to slow down, we need to moderator ---- full of pure water in a nuclear reactor. Aircraft carriers, submarines use nuclear reactor control has proven more successful.

Rod: has a strong ability to absorb neutrons, driven by the control rod drive mechanism, can move up and down in a nuclear reactor control rods within the nuclear fuel used to start, shut down the nuclear reactor, and maintain, regulate reactor power. Hafnium control rods in general, silver, indium, cadmium and other metals production.

Control rod drive mechanism: He is the executive body of nuclear reactors operating system and security protection systems, in strict accordance with requirements of the system or its operator control rod drives do move up and down in a nuclear reactor, nuclear reactor for power control. In a crisis situation, you also can quickly control rods fully inserted into the reactor in order to achieve the purpose of the emergency shutdown

Upper and lower support plate: used to secure the fuel assembly. High temperature and pressure inside the reactor is filled with pure water (so called pressurized water reactors), on the one hand he was passing through a nuclear reactor core, cooling the nuclear fuel, to act as a coolant, on the other hand it accumulates in the pressure vessel in play moderated neutrons role, acting as moderator.

Water quality monitoring sampling system:

Adding chemical system: under normal circumstances, for adding hydrazine, hydrogen, pH control agents to the primary coolant system, the main purpose is to remove and reduce coolant oxygen, high oxygen water suppression equipment wall corrosion (usually at a high temperature oxygen with hydrogen, especially at low temperatures during startup of a nuclear reactor with added hydrazine oxygen); when the nuclear reactor control rods stuck for some reason can not shutdown time by the the system can inject the nuclear reactor neutron absorber (such as boric acid solution), emergency shutdown, in order to ensure the safety of nuclear submarines.

Water system: a loop inside the water will be reduced at work, such as water sampling and analysis, equipment leaks, because the shutdown process cooling water and reduction of thermal expansion and contraction.

Equipment cooling water system:

Pressure safety systems: pressure reactor primary coolant system may change rapidly for some reason, the need for effective control. And in severe burn nuclear fuel rods, resulting in a core melt accident, it is necessary to promptly increase the pressure. Turn the regulator measures the electric, heating and cooling water. If necessary, also temporary startup booster pump.

Residual Heat Removal System: reactor scram may be due to an accident, such as when the primary coolant system of the steam generator heat exchanger tube is damaged, it must be urgently closed reactors.

Safety Injection System: The main components of this system is the high-pressure injection pump.

Radioactive waste treatment systems:

Decontamination Systems: for the removal of radioactive deposits equipment, valves, pipes and accessories, and other surfaces.

Europe, the United States and Russia and other countries related to aircraft carriers, submarines, icebreakers, nuclear-powered research aircraft, there are lots of achievements use of nuclear energy, it is worth analysis. However, nuclear reactor technology, rocket ships and the former are very different, therefore, requires special attention and innovative research. Must adopt a new new design techniques, otherwise, fall into the stereotype, it will avail, nothing even cause harm Aerospace.

In astronaut body heat is too high, water-cooled ventilation clothing and clothing to a different way of heat. If the body heat production more than 350 kcal / h (ventilated clothes can not meet the cooling requirements, then that is cooled by a water-cooled suit. Ventilating clothing and water-cooled multi-use compression clothing, durable, flexible plastic tubing, such as polyvinyl chloride pipe or nylon film.

④ airtight limiting layer:

⑤ insulation: astronaut during extravehicular activities, from hot or cold insulation protection. It multilayer aluminized polyester film or a polyimide film and sandwiched between layers of nonwoven fabric to be made.

People call it the “crown jewel” of the Oregon State Parks system, and once you visit, you know why. Silver Falls State Park is the kind of standout scenic treasure that puts Oregon firmly onto the national—and international—stage. Its beauty, boundless recreational opportunities and historic presence keep it there. Nestled in the foothills of Oregon’s Cascade Mountains, less than an hour east of the state capital of Salem, Oregon, the sprawling 9,200 acre property is the largest state park in Oregon, and one of the most popular.

Waterfalls: Where else can you walk behind a waterfall? Check out the famous South Falls and see what a 177-foot curtain of water looks like from behind. It’s part of the Trail of Ten Falls, a spectacular, nationally recognized hiking trail that weaves through a dense forested landscape. The trail passes a series of breathtaking waterfalls along a rocky canyon, and descends to a winding creek at the forest floor. This 7.2 mile loop is considered to be a moderate hike, with an overall elevation change of 800 feet. Several connecting trails with separate access points make shorter routes. For everyone’s safety— absolutely no pets.

Boots, bikes, paws, hooves: The park offers more than 25 miles of backcountry trails for mountain biking, hiking or horseback riding. The trails are lined with lush vegetation and remnants of old-growth forests. Wildlife is abundant. Bears and cougars live in the more remote park areas.

Daytime activities: The South Falls Day-use area has spacious lawns, barbecue stands, picnic shelters, tables, a playground, horseshoe pits, an off lead area for dogs, and a charming creek. Ever since the opening day in 1933, visitors have been using these grounds for potlucks, family reunions and weddings, all within a short walk to view the famous 177-foot South Falls.

Overnight: The main campground has tent sites, RV spots and cabins. Bring your horse and stay in the horse campground. If you need an area for many people, the park also has group tent and RV camps, dormitory-style bunkhouses (each Ranch sleeps 75) and the historic Youth Camp for up to 250 campers.

The Silver Falls Lodge and Conference Center offers a variety of amenities for all visitors to the park. Relax and enjoy comfortable lodging within the wooded setting, or feast at the many catered specialty events.

Animals in Pools Fountains SW Yamhill & Morrison streets between 5th & 6th avenues 1986 • Georgia Gerber • bronze, concrete Eleven " pools" feature sculptures of animals native to Oregon. Sea lions, beavers, bears, river otters, ducks and deer line Morrison and Yamhill streets. Sculptor Georgia Gerber wanted to offer " a sense of the wild in the midst of a busy city." In 1991, one of the beloved bear cubs was stolen, but public outcry led to an anonymous tip that the cub was hiding in the bushes in neighboring Washington County. 3. Shemanski Fountain ( Rebecca at the Well) Park Blocks between SW Salmon & Main streets 1926 • Oliver Barrett ( stone) and Carl Linde ( bronze) Joseph Shemanski, the fountain's namesake, was a Polish immigrant who began his career selling clocks on an installment plan; he eventually owned 34 Pacific Coast stores of the Eastern Outfitting Company. Shemanski commissioned this fountain as a gesture of appreciation for the people of Portland who had so warmly welcomed him. His compassion for animals inspired the three pet- level drinking fountains. There are also three human- level fountains. Two years after the initial fountain was erected, Shemanski commissioned the sculpture of Rebecca at the Well, which reflects the biblical tale of Abraham's discovery of a bride for Isaac when he saw Rebecca drawing water for camels. Abraham chose Rebecca for Issac because of her kindness and service. 4. Chimney Fountain North of SW Lincoln Street between 3rd & 4th avenues 1968 • brick The southernmost of downtown fountains, this small structure was erected as part of the South Auditorium Project, the Portland Development Commission's first urban renewal project. The Chimney Fountain gives the illusion that water is flowing between the bricks, as smoke might seep through a chimney. 5. Lovejoy Fountain SW 3rd Avenue, between Lincoln & Harrison streets 1968 • Lawrence Halprin • concrete, brick In an 1843 contest with Francis Pettygrove, Asa Lovejoy, this fountain's namesake, lost two out of three coin tosses and thus the right to name our city after his hometown of Boston. Lovejoy and Pettygrove flipped the coin a second time to determine which of two neighboring parks would be named Lovejoy and which would be named Pettygrove. This beautiful fountain was built in Lovejoy's park and took on his name. With conservation in mind, the Portland Water Bureau fitted the Lovejoy Fountain with a more efficient water pump in 2008. Before installation of the new pump, the fountain took 12 hours to fill. 6. Dreamer Fountain SW 3rd Avenue between Market & Harrison streets 1979 Manuel Izquierdo • Muntz bronze Located in Pettygrove Park, Manuel Izquierdo's design of a reclining woman is made from surplus navy bronze that he bought and cleaned. Izquierdo said, " The Dreamer speaks of hope, of beauty and serenity, of love, and for a better life in our midst." Izquierdo filled the sculpture with foam so that falling rain would make a gentle sound like a kettledrum instead of ringing hollow. Izquierdo is professor emeritus at the Pacific Northwest College of Art. 7. Ira Keller Forecourt Fountain SW 3rd & 4th avenues between Market & Clay streets 1971 • Angela Danadjieva Designed to mimic the majestic waterfalls of Oregon's Cascade Mountains, the Ira Keller Fountain is truly one of Portland's best known landmarks. Formerly named, simply, Forecourt Fountain, it was renamed in 1978 in honor of the first chairman of the Portland Development Commission, Ira Keller, who had a major influence on the rehabilitation of the area. Residents and visitors alike flock to this series of waterfalls and pools which occupy nearly a full acre in downtown Portland's busiest business district. New York Times critic Ada Louise Huxtable declared this " one of the most important urban spaces since the Renaissance." 8. Elk Fountain SW Main between 3rd & 4th avenues 1900 • Roland Perry ( bronze) and H. G. Wright ( stone) Inspired by the Skidmore Fountain, former mayor David Thompson, president of the Oregon Humane Society, donated the money for this fountain as a trough for horses and dogs, and as a reminder of the elk that once lived in the West Hills and used the neighborhood as a feeding ground. Shortly after the statue was erected, a local artist offered to wire the antlers with electric light bulbs for $ 30. The offer was declined. 9. Salmon Street Springs Fountain SW Salmon Street at Gov. Tom McCall Waterfront Park 1978 • Robert Perron • concrete The Salmon Street Springs Fountain is one of Portland's most iconic fountains, majestically spouting water in an array of designs and speeds. A computer changes the pattern of the water display every 20 minutes. At full capacity the fountain recycles 4,924 gallons of water per minute through as many as 137 jets at one time. Taking its name from the winner of a city- wide naming contest, the fountain has become one of Portland's most popular summer hangouts. A large gathering at this fountain's 20- Year Anniversary Celebration in spring 2008, proved that Salmon Street Springs is more popular than ever. Citizens turned out en masse to celebrate its presence, despite rainy conditions and cool temperatures. 10. Skidmore Fountain SW 1st Avenue between W. Burnside & Ankeny streets 1888 • Olin Warner • bronze, granite This fountain, Portland's oldest commissioned public art, stands at what was once the city center. Druggist Stephen Skidmore left $ 5,000 in his will so that " horses, men, and dogs" could have a cold drink. The fountain was sculpted by Olin Warner who modeled the face of his wife on one of the two caryatids. New York critics lamented that the sculpture was in Portland and that it looked down " upon buggies and buck- boards, and shirt- sleeves and slouch hats in Oregon instead of decorating the Central Park." Skidmore Fountain is inscribed with the quote, " Good citizens are the riches of a city" a line from the dedicatory speech by C. E. S. Wood, an attorney and member of the Fountain Committee. For the dedication, brewer Henry Weinhard offered to pipe beer through the fountain, but the chairman of the Fountain Committee declined. For nearly two decades, people drank water from tin cups that hung from the lion's heads on the fountain. 12. Lee Kelly's Fountain SW 6th Avenue & Pine Street 1977 • Lee Kelly • stainless steel Oregon artist Lee Kelly won an international competition to design this sculpture. Kelly has designed several other sculptures in Portland and throughout the Pacific Northwest. In this work, water flows over several 20- foot- tall steel structures. In conjunction with the Regional Arts & Culture Council, the Water Bureau helped to restore Kelly's fountain in 2004. The fountain had become run- down over the years. Opt i o n a l Tour E x t e n s i o n : 13. Jamison Square Fountain 810 NW 11th Avenue ( Jamison Square) • 2002 If you're feeling extra energetic, head over to Jamison Square Fountain. Just across West Burnside and into the Pearl District, Jamison has quickly become one of the city's most popular hot- weather hot spots. Poised as the centerpiece of Jamison Square, the fountain's wading pool offers cool relief to kids, dogs and adults all summer long. It was named in honor of William Jamison, an early advocate of Pearl District development. Somewhat like Oregon's coast, water cascades into shallow pools where it ebbs and flows like the tide. 11. Car Wash Fountain SW 5th Avenue & Ankeny Street 1977 • Carter, Hull, Nishita, McCulley & Baxter • steel This uniquely shaped fountain never washed cars, but the name seems appropriate given its similarity to a car wash. As a precaution for passing pedestrians, a wind gauge shuts off the pumps if the wind speed exceeds 2 miles per hour.

CHAPTER V of My First Summer in the Sierra by John Muir (1911, public domain text)

[Pg 115]

THE YOSEMITE

July 15. Followed the Mono Trail up the eastern rim of the basin nearly to its summit, then turned off southward to a small shallow valley that extends to the edge of the Yosemite, which we reached about noon, and encamped. After luncheon I made haste to high ground, and from the top of the ridge on the west side of Indian Cañon gained the noblest view of the summit peaks I have ever yet enjoyed. Nearly all the upper basin of the Merced was displayed, with its sublime domes and cañons, dark upsweeping forests, and glorious array of white peaks deep in the sky, every feature glowing, radiating beauty that pours into our flesh and bones like heat rays from fire. Sunshine over all; no breath of wind to stir the brooding calm. Never before had I seen so glorious a landscape, so boundless an affluence of sublime mountain beauty. The most extravagant description I might give of this view to any one who has not seen similar landscapes with his own eyes would not so much as hint its grandeur and the spiritual glow that covered it. I shouted and gestic[Pg 116]ulated in a wild burst of ecstasy, much to the astonishment of St. Bernard Carlo, who came running up to me, manifesting in his intelligent eyes a puzzled concern that was very ludicrous, which had the effect of bringing me to my senses. A brown bear, too, it would seem, had been a spectator of the show I had made of myself, for I had gone but a few yards when I started one from a thicket of brush. He evidently considered me dangerous, for he ran away very fast, tumbling over the tops of the tangled manzanita bushes in his haste. Carlo drew back, with his ears depressed as if afraid, and kept looking me in the face, as if expecting me to pursue and shoot, for he had seen many a bear battle in his day.

Following the ridge, which made a gradual descent to the south, I came at length to the brow of that massive cliff that stands between Indian Cañon and Yosemite Falls, and here the far-famed valley came suddenly into view throughout almost its whole extent. The noble walls—sculptured into endless variety of domes and gables, spires and battlements and plain mural precipices—all a-tremble with the thunder tones of the falling water. The level bottom seemed to be dressed like a garden—sunny meadows here and there, and groves of pine and oak; the river of Mercy sweeping in[Pg 117] majesty through the midst of them and flashing back the sunbeams. The great Tissiack, or Half-Dome, rising at the upper end of the valley to a height of nearly a mile, is nobly proportioned and life-like, the most impressive of all the rocks, holding the eye in devout admiration, calling it back again and again from falls or meadows, or even the mountains beyond,—marvelous cliffs, marvelous in sheer dizzy depth and sculpture, types of endurance. Thousands of years have they stood in the sky exposed to rain, snow, frost, earthquake and avalanche, yet they still wear the bloom of youth.

I rambled along the valley rim to the westward; most of it is rounded off on the very brink, so that it is not easy to find places where one may look clear down the face of the wall to the bottom. When such places were found, and I had cautiously set my feet and drawn my body erect, I could not help fearing a little that the rock might split off and let me down, and what a down!—more than three thousand feet. Still my limbs did not tremble, nor did I feel the least uncertainty as to the reliance to be placed on them. My only fear was that a flake of the granite, which in some places showed joints more or less open and running parallel with the face of the cliff, might give way. After[Pg 118] withdrawing from such places, excited with the view I had got, I would say to myself, "Now don't go out on the verge again." But in the face of Yosemite scenery cautious remonstrance is vain; under its spell one's body seems to go where it likes with a will over which we seem to have scarce any control.

After a mile or so of this memorable cliff work I approached Yosemite Creek, admiring its easy, graceful, confident gestures as it comes bravely forward in its narrow channel, singing the last of its mountain songs on its way to its fate—a few rods more over the shining granite, then down half a mile in showy foam to another world, to be lost in the Merced, where climate, vegetation, inhabitants, all are different. Emerging from its last gorge, it glides in wide lace-like rapids down a smooth incline into a pool where it seems to rest and compose its gray, agitated waters before taking the grand plunge, then slowly slipping over the lip of the pool basin, it descends another glossy slope with rapidly accelerated speed to the brink of the tremendous cliff, and with sublime, fateful confidence springs out free in the air.

I took off my shoes and stockings and worked my way cautiously down alongside the rushing flood, keeping my feet and hands pressed firmly on the polished rock. The booming, roaring[Pg 119] water, rushing past close to my head, was very exciting. I had expected that the sloping apron would terminate with the perpendicular wall of the valley, and that from the foot of it, where it is less steeply inclined, I should be able to lean far enough out to see the forms and behavior of the fall all the way down to the bottom. But I found that there was yet another small brow over which I could not see, and which appeared to be too steep for mortal feet. Scanning it keenly, I discovered a narrow shelf about three inches wide on the very brink, just wide enough for a rest for one's heels. But there seemed to be no way of reaching it over so steep a brow. At length, after careful scrutiny of the surface, I found an irregular edge of a flake of the rock some distance back from the margin of the torrent. If I was to get down to the brink at all that rough edge, which might offer slight finger-holds, was the only way. But the slope beside it looked dangerously smooth and steep, and the swift roaring flood beneath, overhead, and beside me was very nerve-trying. I therefore concluded not to venture farther, but did nevertheless. Tufts of artemisia were growing in clefts of the rock near by, and I filled my mouth with the bitter leaves, hoping they might help to prevent giddiness. Then, with a caution not known in ordinary cir[Pg 120]cumstances, I crept down safely to the little ledge, got my heels well planted on it, then shuffled in a horizontal direction twenty or thirty feet until close to the outplunging current, which, by the time it had descended thus far, was already white. Here I obtained a perfectly free view down into the heart of the snowy, chanting throng of comet-like streamers, into which the body of the fall soon separates.

While perched on that narrow niche I was not distinctly conscious of danger. The tremendous grandeur of the fall in form and sound and motion, acting at close range, smothered the sense of fear, and in such places one's body takes keen care for safety on its own account. How long I remained down there, or how I returned, I can hardly tell. Anyhow I had a glorious time, and got back to camp about dark, enjoying triumphant exhilaration soon followed by dull weariness. Hereafter I'll try to keep from such extravagant, nerve-straining places. Yet such a day is well worth venturing for. My first view of the High Sierra, first view looking down into Yosemite, the death song of Yosemite Creek, and its flight over the vast cliff, each one of these is of itself enough for a great life-long landscape fortune—a most memorable day of days—enjoyment enough to kill if that were possible.[Pg 121]

July 16. My enjoyments yesterday afternoon, especially at the head of the fall, were too great for good sleep. Kept starting up last night in a nervous tremor, half awake, fancying that the foundation of the mountain we were camped on had given way and was falling into Yosemite Valley. In vain I roused myself to make a new beginning for sound sleep. The nerve strain had been too great, and again and again I dreamed I was rushing through the air above a glorious avalanche of water and rocks. One time, springing to my feet, I said, "This time it is real—all must die, and where could mountaineer find a more glorious death!"

Left camp soon after sunrise for an all-day ramble eastward. Crossed the head of Indian Basin, forested with Abies magnifica, underbrush mostly Ceanothus cordulatus and manzanita, a mixture not easily trampled over or penetrated, for the ceanothus is thorny and grows in dense snow-pressed masses, and the manzanita has exceedingly crooked, stubborn branches. From the head of the cañon continued on past North Dome into the basin of Dome or Porcupine Creek. Here are many fine meadows imbedded in the woods, gay with Lilium parvum and its companions; the elevation, about eight thousand feet, seems to be best suited for it—saw specimens that[Pg 122] were a foot or two higher than my head. Had more magnificent views of the upper mountains, and of the great South Dome, said to be the grandest rock in the world. Well it may be, since it is of such noble dimensions and sculpture. A wonderfully impressive monument, its lines exquisite in fineness, and though sublime in size, is finished like the finest work of art, and seems to be alive.

July 17. A new camp was made to-day in a magnificent silver fir grove at the head of a small stream that flows into Yosemite by way of Indian Cañon. Here we intend to stay several weeks,—a fine location from which to make excursions about the great valley and its fountains. Glorious days I'll have sketching, pressing plants, studying the wonderful topography and the wild animals, our happy fellow mortals and neighbors. But the vast mountains in the distance, shall I ever know them, shall I be allowed to enter into their midst and dwell with them?

The North and South Domes

The North and South Domes

We were pelted about noon by a short, heavy rainstorm, sublime thunder reverberating among the mountains and cañons,—some strokes near, crashing, ringing in the tense crisp air with startling keenness, while the distant peaks loomed gloriously through the cloud fringes and sheets of rain. Now the[Pg 123] storm is past, and the fresh washed air is full of the essences of the flower gardens and groves. Winter storms in Yosemite must be glorious. May I see them!

Have got my bed made in our new camp,—plushy, sumptuous, and deliciously fragrant, most of it magnifica fir plumes, of course, with a variety of sweet flowers in the pillow. Hope to sleep to-night without tottering nerve-dreams. Watched a deer eating ceanothus leaves and twigs.

July 18. Slept pretty well; the valley walls did not seem to fall, though I still fancied myself at the brink, alongside the white, plunging flood, especially when half asleep. Strange the danger of that adventure should be more troublesome now that I am in the bosom of the peaceful woods, a mile or more from the fall, than it was while I was on the brink of it.

Bears seem to be common here, judging by their tracks. About noon we had another rainstorm with keen startling thunder, the metallic, ringing, clashing, clanging notes gradually fading into low bass rolling and muttering in the distance. For a few minutes the rain came in a grand torrent like a waterfall, then hail; some of the hailstones an inch in diameter, hard, icy, and irregular in form, like those oftentimes seen in Wisconsin. Carlo[Pg 124] watched them with intelligent astonishment as they came pelting and thrashing through the quivering branches of the trees. The cloud scenery sublime. Afternoon calm, sunful, and clear, with delicious freshness and fragrance from the firs and flowers and steaming ground.

July 19. Watching the daybreak and sunrise. The pale rose and purple sky changing softly to daffodil yellow and white, sunbeams pouring through the passes between the peaks and over the Yosemite domes, making their edges burn; the silver firs in the middle ground catching the glow on their spiry tops, and our camp grove fills and thrills with the glorious light. Everything awakening alert and joyful; the birds begin to stir and innumerable insect people. Deer quietly withdraw into leafy hiding-places in the chaparral; the dew vanishes, flowers spread their petals, every pulse beats high, every life cell rejoices, the very rocks seem to thrill with life. The whole landscape glows like a human face in a glory of enthusiasm, and the blue sky, pale around the horizon, bends peacefully down over all like one vast flower.

About noon, as usual, big bossy cumuli began to grow above the forest, and the rainstorm pouring from them is the most imposing I have yet seen. The silvery zigzag lightning[Pg 125] lances are longer than usual, and the thunder gloriously impressive, keen, crashing, intensely concentrated, speaking with such tremendous energy it would seem that an entire mountain is being shattered at every stroke, but probably only a few trees are being shattered, many of which I have seen on my walks hereabouts strewing the ground. At last the clear ringing strokes are succeeded by deep low tones that grow gradually fainter as they roll afar into the recesses of the echoing mountains, where they seem to be welcomed home. Then another and another peal, or rather crashing, splintering stroke, follows in quick succession, perchance splitting some giant pine or fir from top to bottom into long rails and slivers, and scattering them to all points of the compass. Now comes the rain, with corresponding extravagant grandeur, covering the ground high and low with a sheet of flowing water, a transparent film fitted like a skin upon the rugged anatomy of the landscape, making the rocks glitter and glow, gathering in the ravines, flooding the streams, and making them shout and boom in reply to the thunder.

How interesting to trace the history of a single raindrop! It is not long, geologically speaking, as we have seen, since the first raindrops fell on the newborn leafless Sierra land[Pg 126]scapes. How different the lot of these falling now! Happy the showers that fall on so fair a wilderness,—scarce a single drop can fail to find a beautiful spot,—on the tops of the peaks, on the shining glacier pavements, on the great smooth domes, on forests and gardens and brushy moraines, plashing, glinting, pattering, laving. Some go to the high snowy fountains to swell their well-saved stores; some into the lakes, washing the mountain windows, patting their smooth glassy levels, making dimples and bubbles and spray; some into the waterfalls and cascades, as if eager to join in their dance and song and beat their foam yet finer; good luck and good work for the happy mountain raindrops, each one of them a high waterfall in itself, descending from the cliffs and hollows of the clouds to the cliffs and hollows of the rocks, out of the sky-thunder into the thunder of the falling rivers. Some, falling on meadows and bogs, creep silently out of sight to the grass roots, hiding softly as in a nest, slipping, oozing hither, thither, seeking and finding their appointed work. Some, descending through the spires of the woods, sift spray through the shining needles, whispering peace and good cheer to each one of them. Some drops with happy aim glint on the sides of crystals,—quartz, hornblende, garnet, zir[Pg 127]con, tourmaline, feldspar,—patter on grains of gold and heavy way-worn nuggets; some, with blunt plap-plap and low bass drumming, fall on the broad leaves of veratrum, saxifrage, cypripedium. Some happy drops fall straight into the cups of flowers, kissing the lips of lilies. How far they have to go, how many cups to fill, great and small, cells too small to be seen, cups holding half a drop as well as lake basins between the hills, each replenished with equal care, every drop in all the blessed throng a silvery newborn star with lake and river, garden and grove, valley and mountain, all that the landscape holds reflected in its crystal depths, God's messenger, angel of love sent on its way with majesty and pomp and display of power that make man's greatest shows ridiculous.

Now the storm is over, the sky is clear, the last rolling thunder-wave is spent on the peaks, and where are the raindrops now—what has become of all the shining throng? In winged vapor rising some are already hastening back to the sky, some have gone into the plants, creeping through invisible doors into the round rooms of cells, some are locked in crystals of ice, some in rock crystals, some in porous moraines to keep their small springs flowing, some have gone journeying on in the rivers to join the larger raindrop of the ocean.[Pg 128] From form to form, beauty to beauty, ever changing, never resting, all are speeding on with love's enthusiasm, singing with the stars the eternal song of creation.

July 20. Fine calm morning; air tense and clear; not the slightest breeze astir; everything shining, the rocks with wet crystals, the plants with dew, each receiving its portion of irised dewdrops and sunshine like living creatures getting their breakfast, their dew manna coming down from the starry sky like swarms of smaller stars. How wondrous fine are the particles in showers of dew, thousands required for a single drop, growing in the dark as silently as the grass! What pains are taken to keep this wilderness in health,—showers of snow, showers of rain, showers of dew, floods of light, floods of invisible vapor, clouds, winds, all sorts of weather, interaction of plant on plant, animal on animal, etc., beyond thought! How fine Nature's methods! How deeply with beauty is beauty overlaid! the ground covered with crystals, the crystals with mosses and lichens and low-spreading grasses and flowers, these with larger plants leaf over leaf with ever-changing color and form, the broad palms of the firs outspread over these, the azure dome over all like a bell-flower, and star above star.[Pg 129]

Yonder stands the South Dome, its crown high above our camp, though its base is four thousand feet below us; a most noble rock, it seems full of thought, clothed with living light, no sense of dead stone about it, all spiritualized, neither heavy looking nor light, steadfast in serene strength like a god.

Our shepherd is a queer character and hard to place in this wilderness. His bed is a hollow made in red dry-rot punky dust beside a log which forms a portion of the south wall of the corral. Here he lies with his wonderful everlasting clothing on, wrapped in a red blanket, breathing not only the dust of the decayed wood but also that of the corral, as if determined to take ammoniacal snuff all night after chewing tobacco all day. Following the sheep he carries a heavy six-shooter swung from his belt on one side and his luncheon on the other. The ancient cloth in which the meat, fresh from the frying-pan, is tied serves as a filter through which the clear fat and gravy juices drip down on his right hip and leg in clustering stalactites. This oleaginous formation is soon broken up, however, and diffused and rubbed evenly into his scanty apparel, by sitting down, rolling over, crossing his legs while resting on logs, etc., making shirt and trousers water-tight and shiny. His trousers, in parti[Pg 130]cular, have become so adhesive with the mixed fat and resin that pine needles, thin flakes and fibres of bark, hair, mica scales and minute grains of quartz, hornblende, etc., feathers, seed wings, moth and butterfly wings, legs and antennæ of innumerable insects, or even whole insects such as the small beetles, moths and mosquitoes, with flower petals, pollen dust and indeed bits of all plants, animals, and minerals of the region adhere to them and are safely imbedded, so that though far from being a naturalist he collects fragmentary specimens of everything and becomes richer than he knows. His specimens are kept passably fresh, too, by the purity of the air and the resiny bituminous beds into which they are pressed. Man is a microcosm, at least our shepherd is, or rather his trousers. These precious overalls are never taken off, and nobody knows how old they are, though one may guess by their thickness and concentric structure. Instead of wearing thin they wear thick, and in their stratification have no small geological significance.

Besides herding the sheep, Billy is the butcher, while I have agreed to wash the few iron and tin utensils and make the bread. Then, these small duties done, by the time the sun is fairly above the mountain-tops I am[Pg 131] beyond the flock, free to rove and revel in the wilderness all the big immortal days.

Sketching on the North Dome. It commands views of nearly all the valley besides a few of the high mountains. I would fain draw everything in sight—rock, tree, and leaf. But little can I do beyond mere outlines,—marks with meanings like words, readable only to myself,—yet I sharpen my pencils and work on as if others might possibly be benefited. Whether these picture-sheets are to vanish like fallen leaves or go to friends like letters, matters not much; for little can they tell to those who have not themselves seen similar wildness, and like a language have learned it. No pain here, no dull empty hours, no fear of the past, no fear of the future. These blessed mountains are so compactly filled with God's beauty, no petty personal hope or experience has room to be. Drinking this champagne water is pure pleasure, so is breathing the living air, and every movement of limbs is pleasure, while the whole body seems to feel beauty when exposed to it as it feels the camp-fire or sunshine, entering not by the eyes alone, but equally through all one's flesh like radiant heat, making a passionate ecstatic pleasure-glow not explainable. One's body then seems homogeneous throughout, sound as a crystal.[Pg 132] Perched like a fly on this Yosemite dome, I gaze and sketch and bask, oftentimes settling down into dumb admiration without definite hope of ever learning much, yet with the longing, unresting effort that lies at the door of hope, humbly prostrate before the vast display of God's power, and eager to offer self-denial and renunciation with eternal toil to learn any lesson in the divine manuscript.

It is easier to feel than to realize, or in any way explain, Yosemite grandeur. The magnitudes of the rocks and trees and streams are so delicately harmonized they are mostly hidden. Sheer precipices three thousand feet high are fringed with tall trees growing close like grass on the brow of a lowland hill, and extending along the feet of these precipices a ribbon of meadow a mile wide and seven or eight long, that seems like a strip a farmer might mow in less than a day. Waterfalls, five hundred to one or two thousand feet high, are so subordinated to the mighty cliffs over which they pour that they seem like wisps of smoke, gentle as floating clouds, though their voices fill the valley and make the rocks tremble. The mountains, too, along the eastern sky, and the domes in front of them, and the succession of smooth rounded waves between, swelling higher, higher, with dark woods in[Pg 133] their hollows, serene in massive exuberant bulk and beauty, tend yet more to hide the grandeur of the Yosemite temple and make it appear as a subdued subordinate feature of the vast harmonious landscape. Thus every attempt to appreciate any one feature is beaten down by the overwhelming influence of all the others. And, as if this were not enough, lo! in the sky arises another mountain range with topography as rugged and substantial-looking as the one beneath it—snowy peaks and domes and shadowy Yosemite valleys—another version of the snowy Sierra, a new creation heralded by a thunder-storm. How fiercely, devoutly wild is Nature in the midst of her beauty-loving tenderness!—painting lilies, watering them, caressing them with gentle hand, going from flower to flower like a gardener while building rock mountains and cloud mountains full of lightning and rain. Gladly we run for shelter beneath an overhanging cliff and examine the reassuring ferns and mosses, gentle love tokens growing in cracks and chinks. Daisies, too, and ivesias, confiding wild children of light, too small to fear. To these one's heart goes home, and the voices of the storm become gentle. Now the sun breaks forth and fragrant steam arises. The birds are out singing on the edges of the[Pg 134] groves. The west is flaming in gold and purple, ready for the ceremony of the sunset, and back I go to camp with my notes and pictures, the best of them printed in my mind as dreams. A fruitful day, without measured beginning or ending. A terrestrial eternity. A gift of good God.

Wrote to my mother and a few friends, mountain hints to each. They seem as near as if within voice-reach or touch. The deeper the solitude the less the sense of loneliness, and the nearer our friends. Now bread and tea, fir bed and good-night to Carlo, a look at the sky lilies, and death sleep until the dawn of another Sierra to-morrow.

July 21. Sketching on the Dome—no rain; clouds at noon about quarter filled the sky, casting shadows with fine effect on the white mountains at the heads of the streams, and a soothing cover over the gardens during the warm hours.

Saw a common house-fly and a grasshopper and a brown bear. The fly and grasshopper paid me a merry visit on the top of the Dome, and I paid a visit to the bear in the middle of a small garden meadow between the Dome and the camp where he was standing alert among the flowers as if willing to be seen to advantage. I had not gone more than half a[Pg 135] mile from camp this morning, when Carlo, who was trotting on a few yards ahead of me, came to a sudden, cautious standstill. Down went tail and ears, and forward went his knowing nose, while he seemed to be saying, "Ha, what's this? A bear, I guess." Then a cautious advance of a few steps, setting his feet down softly like a hunting cat, and questioning the air as to the scent he had caught until all doubt vanished. Then he came back to me, looked me in the face, and with his speaking eyes reported a bear near by; then led on softly, careful, like an experienced hunter, not to make the slightest noise; and frequently looking back as if whispering, "Yes, it's a bear; come and I'll show you." Presently we came to where the sunbeams were streaming through between the purple shafts of the firs, which showed that we were nearing an open spot, and here Carlo came behind me, evidently sure that the bear was very near. So I crept to a low ridge of moraine boulders on the edge of a narrow garden meadow, and in this meadow I felt pretty sure the bear must be. I was anxious to get a good look at the sturdy mountaineer without alarming him; so drawing myself up noiselessly back of one of the largest of the trees I peered past its bulging buttresses, exposing only a part of my head,[Pg 136] and there stood neighbor Bruin within a stone's throw, his hips covered by tall grass and flowers, and his front feet on the trunk of a fir that had fallen out into the meadow, which raised his head so high that he seemed to be standing erect. He had not yet seen me, but was looking and listening attentively, showing that in some way he was aware of our approach. I watched his gestures and tried to make the most of my opportunity to learn what I could about him, fearing he would catch sight of me and run away. For I had been told that this sort of bear, the cinnamon, always ran from his bad brother man, never showing fight unless wounded or in defense of young. He made a telling picture standing alert in the sunny forest garden. How well he played his part, harmonizing in bulk and color and shaggy hair with the trunks of the trees and lush vegetation, as natural a feature as any other in the landscape. After examining at leisure, noting the sharp muzzle thrust inquiringly forward, the long shaggy hair on his broad chest, the stiff, erect ears nearly buried in hair, and the slow, heavy way he moved his head, I thought I should like to see his gait in running, so I made a sudden rush at him, shouting and swinging my hat to frighten him, expecting to see him make[Pg 137] haste to get away. But to my dismay he did not run or show any sign of running. On the contrary, he stood his ground ready to fight and defend himself, lowered his head, thrust it forward, and looked sharply and fiercely at me. Then I suddenly began to fear that upon me would fall the work of running; but I was afraid to run, and therefore, like the bear, held my ground. We stood staring at each other in solemn silence within a dozen yards or thereabouts, while I fervently hoped that the power of the human eye over wild beasts would prove as great as it is said to be. How long our awfully strenuous interview lasted, I don't know; but at length in the slow fullness of time he pulled his huge paws down off the log, and with magnificent deliberation turned and walked leisurely up the meadow, stopping frequently to look back over his shoulder to see whether I was pursuing him, then moving on again, evidently neither fearing me very much nor trusting me. He was probably about five hundred pounds in weight, a broad, rusty bundle of ungovernable wildness, a happy fellow whose lines have fallen in pleasant places. The flowery glade in which I saw him so well, framed like a picture, is one of the best of all I have yet discovered, a conservatory of Nature's precious plant people.[Pg 138] Tall lilies were swinging their bells over that bear's back, with geraniums, larkspurs, columbines, and daisies brushing against his sides. A place for angels, one would say, instead of bears.

In the great cañons Bruin reigns supreme. Happy fellow, whom no famine can reach while one of his thousand kinds of food is spared him. His bread is sure at all seasons, ranged on the mountain shelves like stores in a pantry. From one to the other, up or down he climbs, tasting and enjoying each in turn in different climates, as if he had journeyed thousands of miles to other countries north or south to enjoy their varied productions. I should like to know my hairy brothers better—though after this particular Yosemite bear, my very neighbor, had sauntered out of sight this morning, I reluctantly went back to camp for the Don's rifle to shoot him, if necessary, in defense of the flock. Fortunately I couldn't find him, and after tracking him a mile or two towards Mount Hoffman I bade him Godspeed and gladly returned to my work on the Yosemite Dome.

The house-fly also seemed at home and buzzed about me as I sat sketching, and enjoying my bear interview now it was over. I wonder what draws house-flies so far up the[Pg 139] mountains, heavy gross feeders as they are, sensitive to cold, and fond of domestic ease. How have they been distributed from continent to continent, across seas and deserts and mountain chains, usually so influential in determining boundaries of species both of plants and animals. Beetles and butterflies are sometimes restricted to small areas. Each mountain in a range, and even the different zones of a mountain, may have its own peculiar species. But the house-fly seems to be everywhere. I wonder if any island in mid-ocean is flyless. The bluebottle is abundant in these Yosemite woods, ever ready with his marvelous store of eggs to make all dead flesh fly. Bumblebees are here, and are well fed on boundless stores of nectar and pollen. The honeybee, though abundant in the foothills, has not yet got so high. It is only a few years since the first swarm was brought to California.

TRACK OF SINGING DANCING GRASSHOPPER

TRACK OF SINGING DANCING GRASSHOPPER IN THE AIR OVER NORTH DOME

A queer fellow and a jolly fellow is the grasshopper. Up the mountains he comes on excursions, how high I don't know, but at least as far and high as Yosemite tourists. I was much interested with the hearty enjoyment of the one that danced and sang for me on the Dome this afternoon. He seemed brimful of glad, hilarious energy, manifested by springing[Pg 140] into the air to a height of twenty or thirty feet, then diving and springing up again and making a sharp musical rattle just as the lowest point in the descent was reached. Up and down a dozen times or so he danced and sang, then alighted to rest, then up and at it again. The curves he described in the air in diving and rattling resembled those made by cords hanging loosely and attached at the same height at the ends, the loops nearly covering each other. Braver, heartier, keener, care-free enjoyment of life I have never seen or heard in any creature, great or small. The life of this comic redlegs, the mountain's merriest child, seems to be made up of pure, condensed gayety. The Douglas squirrel is the only living creature that I can compare him with in exuberant, rollicking, irrepressible jollity. Wonderful that these sublime mountains are so loudly cheered and brightened by a creature so queer. Nature in him seems to be snapping her fingers in the face of all earthly dejection and melancholy with a boyish hip-hip-hurrah. How the sound is made I do not understand. When he was on the ground he made not the slightest noise, nor when he was simply flying from place to place, but only when diving in curves, the motion seeming to be required for the sound; for the more vigorous the diving the more ener[Pg 141]getic the corresponding outbursts of jolly rattling. I tried to observe him closely while he was resting in the intervals of his performances; but he would not allow a near approach, always getting his jumping legs ready to spring for immediate flight, and keeping his eyes on me. A fine sermon the little fellow danced for me on the Dome, a likely place to look for sermons in stones, but not for grasshopper sermons. A large and imposing pulpit for so small a preacher. No danger of weakness in the knees of the world while Nature can spring such a rattle as this. Even the bear did not express for me the mountain's wild health and strength and happiness so tellingly as did this comical little hopper. No cloud of care in his day, no winter of discontent in sight. To him every day is a holiday; and when at length his sun sets, I fancy he will cuddle down on the forest floor and die like the leaves and flowers, and like them leave no unsightly remains calling for burial.

Sundown, and I must to camp. Good-night, friends three,—brown bear, rugged boulder of energy in groves and gardens fair as Eden; restless, fussy fly with gauzy wings stirring the air around all the world; and grasshopper, crisp, electric spark of joy enlivening the massy sublimity of the mountains like the laugh of a[Pg 142] child. Thank you, thank you all three for your quickening company. Heaven guide every wing and leg. Good-night friends three, good-night.

July 22. A fine specimen of the black-tailed deer went bounding past camp this morning. A buck with wide spread of antlers, showing admirable vigor and grace. Wonderful the beauty, strength, and graceful movements of animals in wildernesses, cared for by Nature only, when our experience with domestic animals would lead us to fear that all the so-called neglected wild beasts would degenerate. Yet the upshot of Nature's method of breeding and teaching seems to lead to excellence of every sort. Deer, like all wild animals, are as clean as plants. The beauties of their gestures and attitudes, alert or in repose, surprise yet more than their bounding exuberant strength. Every movement and posture is graceful, the very poetry of manners and motion. Mother Nature is too often spoken of as in reality no mother at all. Yet how wisely, sternly, tenderly she loves and looks after her children in all sorts of weather and wildernesses. The more I see of deer the more I admire them as mountaineers. They make their way into the heart of the roughest solitudes with smooth reserve of strength, through dense belts of brush and for[Pg 143]est encumbered with fallen trees and boulder piles, across cañons, roaring streams, and snow-fields, ever showing forth beauty and courage. Over nearly all the continent the deer find homes. In the Florida savannas and hummocks, in the Canada woods, in the far north, roaming over mossy tundras, swimming lakes and rivers and arms of the sea from island to island washed with waves, or climbing rocky mountains, everywhere healthy and able, adding beauty to every landscape,—a truly admirable creature and great credit to Nature.

Have been sketching a silver fir that stands on a granite ridge a few hundred yards to the eastward of camp—a fine tree with a particular snow-storm story to tell. It is about one hundred feet high, growing on bare rock, thrusting its roots into a weathered joint less than an inch wide, and bulging out to form a base to bear its weight. The storm came from the north while it was young and broke it down nearly to the ground, as is shown by the old, dead, weather-beaten top leaning out from the living trunk built up from a new shoot below the break. The annual rings of the trunk that have overgrown the dead sapling tell the year of the storm. Wonderful that a side branch forming a portion of one of the level collars that encircle the trunk of this species (Abies[Pg 144] magnifica) should bend upward, grow erect, and take the place of the lost axis to form a new tree.

Many others, pines as well as firs, bear testimony to the crushing severity of this particular storm. Trees, some of them fifty to seventy-five feet high, were bent to the ground and buried like grass, whole groves vanishing as if the forest had been cleared away, leaving not a branch or needle visible until the spring thaw. Then the more elastic undamaged saplings rose again, aided by the wind, some reaching a nearly erect attitude, others remaining more or less bent, while those with broken backs endeavored to specialize a side branch below the break and make a leader of it to form a new axis of development. It is as if a man, whose back was broken or nearly so and who was compelled to go bent, should find a branch backbone sprouting straight up from below the break and should gradually develop new arms and shoulders and head, while the old damaged portion of his body died.

Grand white cloud mountains and domes created about noon as usual, ridges and ranges of endless variety, as if Nature dearly loved this sort of work, doing it again and again nearly every day with infinite industry, and producing beauty that never palls. A few zig[Pg 145]zags of lightning, five minutes' shower, then a gradual wilting and clearing.

July 23. Another midday cloudland, displaying power and beauty that one never wearies in beholding, but hopelessly unsketchable and untellable. What can poor mortals say about clouds? While a description of their huge glowing domes and ridges, shadowy gulfs and cañons, and feather-edged ravines is being tried, they vanish, leaving no visible ruins. Nevertheless, these fleeting sky mountains are as substantial and significant as the more lasting upheavals of granite beneath them. Both alike are built up and die, and in God's calendar difference of duration is nothing. We can only dream about them in wondering, worshiping admiration, happier than we dare tell even to friends who see farthest in sympathy, glad to know that not a crystal or vapor particle of them, hard or soft, is lost; that they sink and vanish only to rise again and again in higher and higher beauty. As to our own work, duty, influence, etc., concerning which so much fussy pother is made, it will not fail of its due effect, though, like a lichen on a stone, we keep silent.

July 24. Clouds at noon occupying about half the sky gave half an hour of heavy rain to wash one of the cleanest landscapes in the[Pg 146] world. How well it is washed! The sea is hardly less dusty than the ice-burnished pavements and ridges, domes and cañons, and summit peaks plashed with snow like waves with foam. How fresh the woods are and calm after the last films of clouds have been wiped from the sky! A few minutes ago every tree was excited, bowing to the roaring storm, waving, swirling, tossing their branches in glorious enthusiasm like worship. But though to the outer ear these trees are now silent, their songs never cease. Every hidden cell is throbbing with music and life, every fibre thrilling like harp strings, while incense is ever flowing from the balsam bells and leaves. No wonder the hills and groves were God's first temples, and the more they are cut down and hewn into cathedrals and churches, the farther off and dimmer seems the Lord himself. The same may be said of stone temples. Yonder, to the eastward of our camp grove, stands one of Nature's cathedrals, hewn from the living rock, almost conventional in form, about two thousand feet high, nobly adorned with spires and pinnacles, thrilling under floods of sunshine as if alive like a grove-temple, and well named "Cathedral Peak." Even Shepherd Billy turns at times to this wonderful mountain building, though apparently deaf to all stone sermons. Snow that re[Pg 147]fused to melt in fire would hardly be more wonderful than unchanging dullness in the rays of God's beauty. I have been trying to get him to walk to the brink of Yosemite for a view, offering to watch the sheep for a day, while he should enjoy what tourists come from all over the world to see. But though within a mile of the famous valley, he will not go to it even out of mere curiosity. "What," says he, "is Yosemite but a cañon—a lot of rocks—a hole in the ground—a place dangerous about falling into—a d——d good place to keep away from." "But think of the waterfalls, Billy—just think of that big stream we crossed the other day, falling half a mile through the air—think of that, and the sound it makes. You can hear it now like the roar of the sea." Thus I pressed Yosemite upon him like a missionary offering the gospel, but he would have none of it. "I should be afraid to look over so high a wall," he said. "It would make my head swim. There is nothing worth seeing anywhere, only rocks, and I see plenty of them here. Tourists that spend their money to see rocks and falls are fools, that's all. You can't humbug me. I've been in this country too long for that." Such souls, I suppose, are asleep, or smothered and befogged beneath mean pleasures and cares.

July 25. Another cloudland. Some clouds[Pg 148] have an over-ripe decaying look, watery and bedraggled and drawn out into wind-torn shreds and patches, giving the sky a littered appearance; not so these Sierra summer midday clouds. All are beautiful with smooth definite outlines and curves like those of glacier-polished domes. They begin to grow about eleven o'clock, and seem so wonderfully near and clear from this high camp one is tempted to try to climb them and trace the streams that pour like cataracts from their shadowy fountains. The rain to which they give birth is often very heavy, a sort of waterfall as imposing as if pouring from rock mountains. Never in all my travels have I found anything more truly novel and interesting than these midday mountains of the sky, their fine tones of color, majestic visible growth, and ever-changing scenery and general effects, though mostly as well let alone as far as description goes. I oftentimes think of Shelley's cloud poem, "I sift the snow on the mountains below."
