be 6522 times taller At least so he would appear when viewed under the new superpower ultra-violmicroscope which recently has been perfected and may well be considered one of today’s seven CAN et

practical uses are enormous Ultra-violsuper will tell much more about the strength and construction of metals It is expected to tell why metals grow "fatigued” or brittle and 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 them minute cracks develop These cracks have been so small that ordinary microscopes have not revealed them Using ultra-viollight and enormous magnifying power they are now made visible and can be studied Is et et ‘Making Electricity from Wirid T w ' found the correct pitch for a steamship’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 lee 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 is according to Mr Gilmour one that corresponds to the middle range of the keyboard of a piano Now whistles on all Alaska-boun- d ships of this steamship line are being tuned to this successful pitch In experimenting with the vast ower locked up in

adage says that "it is ill will 4 that blows nobody good” Now science goes wisdom one better and even puts Idle winds to work The first step m this direction recently was taken by the constructor of the Koenigswuster-hause- n radio tower power hard-cooke- w bricks light enough to float yet strong enough to support their weight if built into a tower 6250 feet high which is five times the height of the Empire State Building in New York City recently were demonstrated by Dr Charles Burgess h These floating bricks aie only the weight of an ordinary brick of high quality porous yet resistant to the entrance of water and of a crushing strength sufficient to support their weight if built into a h miles tower nearly one and high it has been found that it takes a seconds to lay one bricklayer sixty-fiv- e 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 lt Mr Weiss then suggested the making of a new brick so that a bricklayer will be enabled o 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 tho process is still in the development stages and the technical practice has not been perfected works in one-fift- Giant Wind Wheels Mounted on Steel Towers Nearly 900 Feet High and Germany toward providing that entire country

Befoie 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 fish 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 complete IndeTherefore

Generators for Developing Cheap Electrical Power :3k hard-cooke- heat-insulati- Are Salty MOT there are dozens of facts about eggs which are not generally understood an explanation of a few of the most puzzling ones will probably be welcomed What is the dark ring which sometimes forms 8round a d egg yolk? How can it be prevented? This ring as Marion Baily King explains 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 alIt though unattractive in appearance can be prevented by cooking the egg at a low or moderate temperature as the union of the two egg minerals only takes place at high temperature or under long continued heat Blunging the egg into cold water when cooked also helps to prevent such a ring d Why when eggs are shelled does the white separate easily into layers especially if some of the white clings to the shell? Because the egg yolk as it passed down the egg - canal of the hen revolves and causes the white to be deposited on the yolk in layers as it turns Are egg yolks richer in nutrients than d 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 S' one-fift- Why Your Tears niiiisMiHM Rings m Egg CLAY - -- fTt Floating Bricks Made of Clay has been done in the past after numerous attempts but more by accident than anything else But now Mr J D Gilmour of Seattle the steamship company’s port engineer states that he has -- v cross-sectio- lemon-colore- Breaking Up a Glacier With a Ship7s Whistle ONAL bomba in the form of blasts from the powerful whistles are to be thrown by steamships at the face of Taku Glacier tins Summer and icebergs loosened by the resulting vibrations are expected to brean off from the famous mass of ice 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 ukAM 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 microAttempts scope opens new worlds are now being made to study the — cells smallest living units single By each means of such layer of the single cell can be photo-- ’ The Upper Illustration Shows a Tong A sufgraphed and then studied ficient number of pictures can be Nut from Which Oil Used in Making Below Is a made which will enable the scientist to Varnish Is Ixtrarted n View of the Kernel of ai learn the working of the cell and its t construction There are scientists who Tung Nut Fach of the Three to Eight n believe that a study of Seeds of W hich Average 21 Per Cent of Their Weight in Oil this kind may reveal the secret of life and why and how the cells move and have their being - deep-yello- high-power- of this marvel v Cross-Sectio- 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 adjustment is necessary in the mechanical Shown the New Super Ultra-violK hit h Use Device light Quart!
