Putting Industrial "Criminals" Behind the Bars How Science Solves the Mysteries of “Kidnaped” Power and How Iron Gets in Sugar-Cane. ABiae irom ms assign ox tnese ma chine* there are two factor* that must be coneidered by the general I engineering laboratory In thia ■tudy, two clues npon which the whole case hinge*. These are heat treatment and the composition of materials used, and so, at the very beginning of the study, the field of inves tigation is severely limited. The criminal in the case—mag netic lose—leaves a clear trail behind, but haa a head start. The composition and heat treatment of various alloys have been thoroughly studied to the end of reducing losses. In addition to the result orig inally sought the studies have brought forth magnetic ma terials having a greatly in creased response — that is, manir timae 4- Vi a raanaeiaa daw Testing ■ Radio Coll for (he Number of Turn* by Means of an Electrical Coaming The Coil Winding Count !• Registered on a Galvanometer and la Correct With a V of One-Half of One Per Cent. / Device. arlation "HO put iron in the sugar cane? What makes power mysteriously . disappear from generating ma itnery? What causes insulation to become •hort-cireuited? Wi ehtnery? The answers to these questions are the solutions of mysteries in the indus trial world which has its own class of “criminals.” The detectives of industry are constantly at work running down these malefactors. These keen sleuths, working in gruat, darkened laboratories, almost every day are able to send out solutions of mysteries that would baffle the most expert investigator. Mr. Sher lock Holmes, for example, would have to saw many weary hours on his violin before he could determine the number of windings in a completed radio coil un less he took the coil apart.. In these research laboratories there Is headline news—giant x-ray tubes, elec tric eyes doing human tasks, hi^h-fre quency machines curing dread diseases and ten million vclts of artificial light ninsr crashing through the darkneea of a Hteel vault. Headquarters of one cf these staffs of Industrial detectives is found In the en gineering laboratories of the General Electric Company, where the celebrated case of the kidnaping of power through magnetic losses keeps one detail of these detectives on duty day and night. The case is never placed in the file marked “closed.” As new victories are chalked up they are made public to interested engineering groups, but the chase goes on. The engineer, who is the “inspector" in this particular branch of industrial crime, estimates that because of the im provement, in magnetic materials in re cent years the magnetic losses in ma chines have been cut to the extent of from one-half to two-thirds watts per pound, a statement that is unexciting at first, glance unti-1 it. is figured out in terms of the dollars saved in the im mense poundage of such machinery used by all industry.

Maybe you i iU o4> uc would not care to taste such freak foods without which no dinners in different parts of the world are complete. Bummalo, for instance, is a tiny trans parent fish used for flavoring curry. Not unlike a smelt in size and appearance, the fish is found on the seashore in most parts of Southern Asia. It has a power ful aroma when warmed, and with most people in this hemisphere is decidedly an ‘‘acauired taste.” Another odd dish is beche-de-mer, the name given by the Portuguese to the sea cucumber. The substance is used in making soup, and costs as much as two dollars a pound. y Edible seaweed, vanilla pods and bou targue, the roe of a species of mullet preserved in beeswax, are other items that tempt many appetites. I Sharks’ fins are used for soup, a plate of which, flavored with this delicacy, would cost as much as a dollar and a quarter or more. The fins are obtained from a small species of shark found off the coasts of Australia and New Zea land. Pickled cocks’ combs are sold under the name of Unanciere which is an ax pensive delicacy. Poppadums are an equally unknown dish which is very palatable. They con sist of a mixture of finely-ground split peas mixed with a special kind of butter. Edible birds’ nest from China and Japan form a dish that is popular with millions of people. It consists of thin, , gelatine-like sections of the nest, made , of the saliva of the swift, which makes Its home in caves on the coast in the East Indies, Japan and China. So highly esteemed is this strange substance, which is eaten with soup, that a con- i siderable industry is devoted to collect- I mg the nests, preparing them for export, 1 end distributing them to all parts of the 1 world. The price is about forty dollars s pound. A . r the same amount of energy ap plied. For aa a material be comes increasingly difficult to magnetize, it also holds that Companies today purchase steel for machines on the basis of a guarantee of ao many watts per pound loss at a given flux density and frequency. The com plicated researches of the engineering laboratory are boiled down to numbers and symbols which give this informa tion. Among recent eases is that of the short-circuits in insulated wire, and how the wrong-doing element was caught in the crafty magnetic net In one factory Sample* of Asbestos Are Placed In a Tube Which I* Inserted in Thia Testing Device. The Indicator Immediately Registers the Percentage of Iron in the Material. producing wire it was found that as Destos applied to copper for insulation occasionally contained metal. When the wire was tested, it would “short." The engineering laboratory men found the cause of these short-circuits and built a devico which was added to the ma chine used in the insulating. This was so designed as to detect the presence of the metal and stop the machine within an inch of its location. A sugar manufacturer found that sugar-cane did not always melt in the mouth, principally because it became en tangled with pieces of metal. A detec tor which used magnetism was devised to discover the foreign particles. One of the strangest things these en gineering detectives do is to tell with almost uncanny accuracy the number of turns in a radio coil when these wind ings are hidden by the outer covering. By using a device called a turn-counter the process of detection is made simple. A coil of a known number of turns is used as a standard, and the coil to be tested is merely slipped on a pin of the counter, which operates on the direct current reversal method. The coil wind ing count is immediately registered on The Cost of Color in Illumination C light 1 OLORS not only play an Impor tant part In decorative effects in the home, but also in the electric bills. That last fact is too often overlooked. Just what colored walls and ceilings, as well as colored lights, cost in light absorption, is disclosed in the following tables compiled by illuminat ing engineers. White and white ivory average 20 per cent light absorption, according to these authorities, while black, at the other ex treme, rates 99 per cent, with the vari ous colors and shades in between rating the following percentages of light ab sorption: Color Ivory . Primrose Yellow. Grajr (depending on tint) Pink Azure Blue. Sky Blue. Tan . Olive Green . Forest Green .. Cardinal Red. Brown .. Dark Green... Dark Blue. Per cent 29 22 .. 80-80 36 .. 46 .. 60 .. 63 65 79 ... 80 .. 80 81 .. 95 .. 96 WhyFastinglsMorc Harmful to Women FASTING is much more injurious to women than to men, according to Professor H. J. Deuel, of the University of Southern California Med ical School. When women refrain from taking food and starve themselves to gain a slender figure they incur far greater risks to tneir health than do men who undergo similar deprivations. “Women develop a much more pro nounced acidosis during a week’s fast ing than do men," says Professor Deuel. “Tnis condition is associated with the inability of females to oxidise fat dur ing starvation as completely as the male subjects are able to do. For this reason an accumulation of incompletely oxi dized products, which are organic acids, occurs in the female, and typical symp toms of acidosis ensue. “Although none of the ordinaiy lab oratory animals develop an acidosis dur ing fasting, comparable with man, nev ertheless it was snown that fasting male rats are able to oxidize one of these or ganic acids—diacetic acid—much more completely than female rats can.” Professor Deuel found that experi ments on animals may indicate that cer tain operations might reverse this com parative ability to endure starvation as between the sexes. Feeling the Earth's Pulse RECORDS of earthquakes obtained by the large seismograph in stalled in an underground vault at the Seismological Laboratory at Pasa dena, California, yield now facts about earthquakes which may cause scientists to develop new theories about the in terior of the earth. Most seismographs indicate only the dbratory motions of the earth at a given point, but the Pasadena instrument also takes the earth’s pulse by measuring . the relative movements of two different points. It responds only to stretches or impressions and indirectly to vibratory aovements. 4 When it comes to colored lights, col ored bulbs, shades or bowls—the. illumi nating experts point out that the light absorbed by transparent or translucent colored materials (glass) approxi mately .025" thick, averages as follows: Glass Per cent Inside Frost (more than clear). .l%-2 Daylight Blue.30-46 Daylight Blue (sign lamps).... 45-66 Light Amber . 60 Dark Amber... 87 Dense Green .. 95-99 Dense Blue. 99 Colors are attractive, but, as shown, they cost money as reflected in the higher cost of lighting for given illumi nation intensities. By using colors of lower light absorption, a happy compro mise between decorative effect and eco nomical lighting may be struck. Spider Dress SPIDERS are such abhorrent crea tures to look upon that, as every one naturally would expect, these cunning insects could never become an accessory to dress. A case in point is seen in the spider gown pictured in the accompanying il lustration which was among the new autumn and winter creations displayed at a recent exhibition of women’s wear in London. , This costume is described as a charm ing evening gown of white net, with frilled hem and sleeves. Its fascinating feature, however, upon which the inter est of the spectators centered, is the de sign of a spider’s web, carried out in detail in black sequins artistically ar ranged on the back of the gown.

These detectors will count a little more than 40,000 turns and will be correct with a variation of about one-half of one per cent. The amateur who has wound a coil for a home-made radio will stand somewhat in awe of this device. Making Paint Out of Milk MILK is now being used as a raw material for making casein paint which has an advantage of high reflectivity, resulting in approxi mately the same effect under artificial illumination as in the daytime. Casein paints, as the Industrial Bulle tin of Arthur D. Little, Inc., point* out, are not to be thought of a* highly com petitive with oil paints. The latter are best on smooth woodwork, and especially outdoors. Casein paints fill the great need of a decorative and light-reflecting paint which can be applied very easily Dy brush or spray and over even the roughest of materials. While not glossy, its surface is smooth and absolutely free from tackiness. It is singularly resist ant to the accumulation and retention of dirt and prime, making this type of coating particularly suitable for use in cellars, warehouses, and factories, as well as for all temporary constructions. Because of the porosity of its films, casein paint is not recommended for the long-time protection of wood or metal, outdoors. This very porosity to water vapor is not always a disadvantage, however* for it permits casein paints to be applied to plaster while it is still wet, and does not interfere with the proper drying out of the plaster thereafter. Casein paints also have high lime-re sistance, a rare quality in paints, so that they may be used over cement or lime mortar, even while these are still wet. Casein paint is now made in the form of paste, so that mixing for use is much quicker and easier than when the old fashioned powder was used. The Life of A Vivid Contrast in Beauty and Ugli ntu la Shown by the Gorgeously Colored Butterfly as It Condescend* to Alight Upon the Back of the Ugly Bug, Which, No Doubt, Is Greatly Flattered by Such Unexpected Attention. the Butterfly HOW long does a butterfly live? The question does not refer to the human variety such as “flutter in the pageant of a monarch,” as Lord Byron described them, but the beautiful, winged creature that emerges from a chrysalis. Entomologists have found it very dif ficult to state an average age for the butterfly, for so much depends on cir cumstances and the locality in which the insects are born. Weather also has a very great effect on butterflies, curtailing their lives. The insects cannot obtain the nourishment they need to live their full span of life if the days are dreary and sunless. Bad weather affects the life of a moth in the same manner. At dusk many moths feed on nectar from flowering shrubs and bushes, and at regulated hours of the night they have what are knownNas flights; these are for feeding, or mating, or perhaps a little exercise! Bad weather greatly affects all this, and so curtails the life of moths as well as that of butterflies. ■I Butterflies emerging from a chrysalis during cold, wet weath er stand less chance of living. Another difficulty in the way of deter mining the average length of the life of butterflies is the fact that many varie ties of these insects spend the winter in hibernation, and are therefore alive for nine or ten months, whereas the usual life of a butterfly varies from one to two, or perhaps three, weeks, according to L. Hugh Newman, writing in Cham ber s Journal. “The importance of locality,” says Mr. Newman, “will be understood when it is explained that the life of a butterfly is regulated greatly by the amount of nourishment it obtains from flowers, in the form of nectar.” The Correct Method of Hiking T jT TAivJviiNVj strengthens the bones, hardens the muscles, loosens the V V joints, benefits the heart, en riches the blood, speeds up a lazy liver, promotes deep breathing. It improves the figure, maintains normal weight, tones the nerves, sharpens the wits, im proves the complexion. Watch the good walker with his even strides and how he elevates himself on the balls of the toes. Notice, too, that he swings forward the shoulder opposite the advancing steps as he makes every step. There is a simple knack The perfect countryside gait is one adapted to the character of the terrain, the season, and the prevailing weather. On a cold winter’s day the bracing air will accelerate the hiker’s gait during the first two miles. He has now ac quired a comfortable body warhith, and will automatically reduce his speed. The other extreme is a hot summer’s day, conducive to leisurely movements. If the novice is anxious to learn from the veteran, the following tips which Ernest A. Dench gives in Nature Maga one, wjll prove helpful: Try to arrange the trip so that the hardest stretch occurs in the morning, when one’s energy is undiminished. The hiker who delavs his start until late morning or early afternoon loses some of the health benefits attributed to the sunlight’s violet rays. They exist in northern climes between 9 and 3 o’clock m summer, and from 11 to 1 o’clock in winter. It is best to take a steep hill or moun tain at a slow but even pace. Pretend you are stepping out to music—a slow waltz in preference to a fast fox-trot_ and you will soon acquire a sense of 4 rhythm, and then the all-essential meas ured tread. If unaccustomed to climbing, a two-minute rest every 10 minutes will prove desirable. Two short steps are preferable to one long step. This like wise applies to the later descent Fingerprinting Disease Fingerprints are now expected to play as important a part in the detection of disease as in the de tection of crime. Doctor Heinrich Poll, a noted German scientist, after 25 years of ceaseless research, during which time he studied 200,000 fingerprints, an nounces that he has found that these marks not only contain concealed evi dence of the racial or ancestral group into which a person is born, but also hidden signs of inherited tendencies, both mental and physical. During an outbreak of infantile pa ralysis, Doctor Heinrich also discovered that the finger-prints of all the victims showed common characteristics which, apparently, were marks that indicated this particular malady.
