Since the average height of American men i- five feet and eight inches, then the seven-mile monster man would be fi.-Vf'f times taller. At least so he would appear when viewed under the new super power ultra-violet microscope which re cently has been perfected and may well be considered one of today’s seven wonders.

But while this enormous magnifying power could and will be used in bio logical studies, its most likely use will he in the field of mechanics. Photo microscopes of metals are being made with it that will give a new insight into the formation of metals, of alloys, of strength and of weaknesses. t ail Zeiss, of Germany, has long been experimenting with a combination of high-powered lenses and ultra violet light, seeking to unravel the secrets of the infinitely small. He has Breaking Up a Glacier “ With a Ship's Whistle TONAL bombs in the form of blasts from the powerful whistles are to be thrown by steamships at the face of Taku Glacier this Summer and icebergs, loosened by the resulting vibrations are exported to break off from the famous mass of tee and tumble into the sea Members of the technical staff of a Pacific steamship company announce that they have found the exact whistle tone that will loosen the icebergs. This has been done in the past after numer ous attempt', hut more by accident than anything else. But now Mr. J. It. Gilmour of Seattle, the steamship com pany’s port engineer, states that he has found the correct pitch for a steam ship's whistle that will cause an iceberg to break up. Mr. Gilmour discovered that one _ liner in particular has been able to tear ” down more tee than any other ship. Its whistle seemed to possess the correct tonal bomb pitch that set up similar vibrations in the face of the glacier, jarring loose masses of ice. This pitch k, according to Mr. Gilmour, one that corresponds to the. middle range of the keyboard of a piano. Now whistles on all Alaska-bound ships of this steamship line are being tuned to this successful pitch. In experimenting with the vast power locked up in vibrations scientists have found that if a musical note of the correct pitch can be found to set up similar vibrations in the steel skelc^ ton of a great skyscraper or a steel bridge, such structures can be de stroyed by being shaken to pieces.

This invention utilizes an entirely new principle. Short-wave lengths are employed instead of ordinary light. Turning to invisible violet radiation the microscope was constructed of quartz instead of glass. This" has meant absolute accuracy in the grinding, for it is necessary that there shall be no A FAMILIAR old ad age says that “it is an ill will £ that blows nobody good.’’ Now science goes wisdom one better and even puts idle winds to work. The first step in this direction recently was taken by the constructor of the Koenigswuster hausen radio tower power works in Germany toward providing that en tire country with cheap electrical current. Sixty towers of the kind shown in the ac companying illustration, each nearly 900 feet high million pounds and sur- j'$s09RI mounted by giant wind wheels, are to be erected in various parts of Germany and equipped to de velop electrical power. The wheels are to work as generators and deliver current of high power in the so-called ‘'storm position.” Hermann Honnef, a German elec trical engineer, also proposes to erect a tower 1,300 feet high, on the top of which it is. planned to install giant windmills capable of producing about "00 million kilowatt hours annually. The current is to be used to supply heat to hot houses in the vicinity. Why Your Tears Are Salty SALTY tears, according to a theory advanced by Dr. Laurence D. Redway, of Ossining, N. Y., are evidence of man's marine existence in prehistoric times. Before the American Association of Anthropologist, meeting recently at the National Museum in Washington, Dr. Redway told how human tears and even the human eye can be traced back to the days “when you were a fi^h and I was a tadpole,” as it were. This, of course, is based on the theory that all life arose out of the primeval ocean. Man’s eyes. Dr. Redway contends, have never reached pomplete inde pendence of the sea. Therefore, he claims, the body has been forced to manufacture its own supply of sea water, in the form of tears, since it be came adjusted to a land environment. Kla» Feasor** t The New Super-Microscope, Using Invisible Ultra-Violet Light, May at Last Enable Scientists to Discover the Secrets of Living distortion for even the limited light range. The instrument operates about as follows: First, the object to be studied is brought into approximate focus by means of a "searcher eyepiece.’’ This is a bit of fluorescent glass upon which the invisible light gives a visible image. Very fine accuracy of adjust ment is necessary in the mechanical parts. After the focus i* obtained the searcher eyepiece is removed and the camera arrangement is put in its place and several photographs taken by means of ultra-violet light. The practical uses are enormous. Ultra-violet super photo-microscopes will tell much more about the strength and construction of metals. It is ex pected to' tell why metals grow ■‘fatigued,” or brittle arid break. The secrets of crystallization will be better known. One most important discovery has already been made. In heating metals for the purpose of hardening diem minute cracks develop. These cracks have been so small that ordinary microscopes have not revealed them Using ultra-violet light and enormou magnifying power, they are now mad' visible and can be studied. Making Electricity from Wind Giant Wind W heels Mounted on Steel Towers ’Nearly 900 Feet High and Designed to Work as Generators for Developin'? Cheap Electrical Power. In the^value of actual saving this initial discovery will be enormous both in money ana in terms of human safety. In the field of biology the micro scope opens new worlds. Attempts are now being made to study the smallest living units—single colls. By means of such super-microscopes each layer of the single cell can be photo graphed and then studied. A suf ficient number of pictures can be made which will enable the scientist to learn the working of the cell and its ' construction. There are scientists who believe that a cross-section study of this kind may reveal the secret of life and why and how the cells move and have their being. Rings in Eggs SINCE there are dozens of facts about eggs which are not gen erally understood, an explana tion of a few of the most puzzling ones will probably be welcomed. What is the dark ring which some times forms around a hard-cooked egg yolk? How can it be prevented? This ring, as Marion Baily King ex plains in the Forecast, is caused by the uniting of the iron in the yolk with the sulphur m the white, to form an iron salt This salt is not harmful, al though unattractive in appearance. It can be prevented by cooking the egg at a low or moderate temperature, a. the union of the two egg minerals only takes place at high temperature, or under long continued heat. Plunging the egg into cold water, when cooked, also helps to prevent such a ring. W hy, when hard-cooked eggs are dialled, 0oes the white separate easily nto layers, especially if some of the •vhite clings to the shell? Because the egg yolk, as it passed down the egg anal of the hen, revolves and causes the white to he deposited on the yolk in layers, as it turns. Are deep-yellow egg yolk3 richer in nutrients than lemon-colored ones’ This has yet to be proved. It is known that the more green food a. hen eats the deeper the yellow of the yolk. Floating Bricks Made of Clay CLAY bricks light enough to float and yet Strong enough to support their weight if built into a tower 6,250 feet high, which is five times the height of the Empire State Building in New York City, recently were demon strated by Dr. Charles Burgess. These floating bricks are only one fifth the weight of an ordinary brick, * of high beat-insulating quality, porous, yet resistant to the entrance of water, and of a crushing strength sufficient to support their w-eight if built into a tower nearly one and one-fifth miles high. It has been found that it takes a bricklayer sixty-five seconds to lay one brick. This led to an effort to reduce the high cost of building by lightening the brick. It was figured out by Howard F. Weiss, a New York expert, that under prevailing rates, it costs four times as much for the labor of laying a brick in place as it does to manufacture it. Mr. Weiss then suggested the making of a new brick so that a bricklayer will be enabled to lay two bricks with the same amount of physical effort he now uses in laying one. This, in fact, now appears to have been made possible by the floating brick which Dr. Burgess demonstrated, although the process is still in the de velopment stages and the technical practice has not been perfected.

Ilelow Is » Cross-Section Vie** of thr Kernel of * Tung Nut, Karlt of the There to Light Seeds of Which Average 21 f’er Cent of Their Weight in Oil. The Making of Tung Oil A STUDY of the results of se lective planting in- connection with Florida’s newest industry —the production of tung oil-—has shown some most interesting facts. Of trees grown from selected seeds in some instances 90 per cent have run true to the type of the parent tree, while successive selective plantings under cultivation have shown improve ment in type and increased yield. Of the trees planted experimentally 18 years ago, without selection as to seed, five have shown a yearly average per tree over a ten-year period of one and a half gallons of oil, or 38.6 nounds of shelled nuts, while the other five gave an average yearly yield of 12.8 pounds, or less than half a gallon of oil per tree. Plantings at varying distances apart have shown that with selected seed groves can be made to produce oil at the rate of 1,200 pounds per acre per year, and taking the average of the price range for tung oil for the last ten '.yearn, this shows average gross in come yearly of about 3180 an acre. In that section of Florida where the. soil favors growth of tung oil trees, cost of production is very small, and the same acreage yields a secondary profit as grazing ground for horses, cheep or cattle. Planted with cro tal-aria the groves are partially ferti lized, and conditions for gathering the tung on nuts are improved by the graz ing, which makes it easier to find and gather the crop after the nuts fall to the ground. Experiments have proceeded far enough to demonstrate that tung oil. formerly procurable only from China, and used in the finest grades of paint and varnish, can be developed into a source of great additional wealth in large areas in Florida where soil con ditions are suitable for the growth of the turb oil tree. Tests have proved that thA dry nuts with efficient press ing methods yield from 20 to 22 per cent of their weight in oil, while the residue left after pressing the nuts has a by-product value.
