"From this Earth of ours the astronomer's brain intelligence can reach out across 93,000,000 miles of space and determine what the sun is made of, what its temperature is, what the conditions are in the, solar atmosphere, and acquire this information with so much of certainty that we know more of conditions in the solar atmosphere that we do of the terrestrial".-----Dr. S. A. Mitchell.

   Rosy cheeks are not always a sign of good health. Humming birds prefer purple floweres. The distance between Europe and America varies as much as sixty-three feet in a single year. The causes are Lunar tides in solid earth. Cranes live about forty years, turtles about fifty years. If a hole could be punched in a light bulb small enough to let in a million atoms of oxygen a minute, it would take one hundred million years to fill the bulb. Cotton can be as strong as steel. The famous "Southern Cross" airplane flew around the world equipped with propellers made of cotton. They were treated with certain chemicals and compressed into a substance possessing the strength of steel. The piston of a locomotive is always advancing. It returns only in relation to the engine's frame. The human body carries enough electricity in its red corpuscles to keep a twenty-five watt lamp burning for five minutes.
   More Facts About the 200-inch Telescope: The Corning New York Glass Works also molded a companion piece, which is a 1,500-pound mass of glass and an experimental disk poured before the original disk. Described as the largest single piece of glass in the world, this experimental 200-inch disk, poured as a preliminary to the production of the giant mirror for the Mt. Palomar Observatory, will be preserved. It has just been placed in a steel ribbed framework, built in the form of an observatory at Corning, New York. By an act of Congress, mining operations have been prohibited within a three mile range of the observatory containing the 200 inch telescope. This is nescessary because of the delicateness and sensitivity of the telescope and its auxiliary instruments. Visitors will not be admitted to the structure until the visitors gallery is completed, probably the latter part of this year or the early part of the next. The sun's rays, streaming through the skylight of the plant in which it was fabricated, caused so much expansion in the huge 317,000-pound bearing that will be used to carry the million pound weight of the 200 inch telescope, that engineers had to cover it with a "sunbonnet", before craftsman could work the bulk of the steel into a perfect circular shape. A special grinder with five motions had to be designed for grinding the world's largest telescope mirror.
   Quite a few years ago, one Milton Kaletsky, of New York City had the following item in a science and Mechanics magazine, in an It's Been Proven Column: "Falling meteors have caused but two deaths! Although hundreds of meteors strike the earth's surface every year, only twice in recorded history have living creatures been stricken by them--a peasant in India and a cow in Brazil."
