SILVER threads among the gold ii the national financial fabric an becoming of increasing important as a result of the government’s recenl act of nationalizing the precious whiU metal, which is also finding many nev and various uses in industry. The Amer lean government is paying a net prici of. 50.01 cents an ounce for stores ol bulk silver which, it has been estimated may amount to as much as 150,000,00( ounces. All such silver must be turnec over to the government within 90 dayi of the executive order. The nationaliza tion order does not apply to the silver o: which household and commercial articlei are made. Never before has silver played so in dispensable part in daily life as it doe: today. Despite the discussion about sil ver and its use as money, only aboul eight per cent of the silver consumed ir the United States in 1933 went into coin age. The. balance is used for innumer able purposes in science, industry anc the arts. What is believed to be the largesl piece of fine silver ever fabricated ii shown in one of the accompanying illus trations. It measures 18 feet nine inches in length by five feet in height and has been rolled to a thickness of one-eighth of an inch. The dependability of silver for a va riety of industrial purposes makes it eco nomical to employ it in many instances in place of base metals. When worn out or damaged, the silver can be reclaimed further to reduce costs. Silver resists the action of certain acids and is strong 1 and exceedingly durable. Of late it has ; been used quite extensively for food con tainers and helps to preserve food. Large quantities of silver solders are used in the manufacture of refrigerat ing apparatus. The locomotive search 1 light is made more efficient and powerful by the liberal use of silver reflectors. The precious metal is used in parts of certain railroad switches since it is strong and unaffected by wide changes of temperature and thus serves to safe guard the lives of millions of people from one end of the country to the other. It proves so durable and little affected . "Unbreakable" Plastic Material Demonstrating the Unbreakable Plastic Material Which Is Molded Into the Figures of Manikins and Msnr Kinds of Novel ties. Makers of show window manikins, dolls and other molded fig ures which have been made of a fragile plastic ma terial will be inter ested in the inven tion of a new sub stance designed for this purpose, which, according to the in ventor, is unbreak able. < Motion-picture studios are said to have found this new plastic sub stance so well adapted to their use that they are planning to use it in making “dou bles” of movie ac tors for both long shots and “stand ins.” This material, whose composition is a secret, is claimed to be as light as papier machine and to have both the dura bility and the flexi bility of rubber. J Why a Dew Pond Never Goes Dry Tnr* metnoa oi making a dew pond is to dig out the earth to a depth of five feet in the centre, sloping upwards to the sides. The hole is then lined with clay and covered with straw. The straw is covered with lime, but this Hme most not touch the clay lining. A secret substance which is said to be known only to two bachelor brothers liv ing in England is mixed with the lime. Then a layer of earth is hammered down to make tne bed of the pond. After that the pond is left to fill itself, which takes about six months. The scientific explanation is that the layer of dry straw insulates the earth ? r below and prevents heat from passing up to the water in the pond. Thus the water remains cold, causing the mois ture-laden night air to part with its wa ter. Naturally, the heat of the day must cause evaporation of the pond water, but this only increases its coldness and further facilitates condensation. The outstanding fact about old dew ponds is that, despite the longest drought, they never go dry. Many are situated in exposed positions and are used daily by cattle and sheep, but in the face of the most prolonged rainless tspells, when larger ponds and rivers in the valleys are drying up, they remain full and apparently undisturbed. in r by shock and vibration that it is extensively employed in ths form of silver solders and braz ing: alloys in building airplanes, aboard battleships and In mo tor cars. Tons of silver yearly now go into the making of silver sol ders and brazing alloys. A new brazing alloy recently devel oped is meeting wide-spread success for non-ferrous metal work and its uses are spreading rapidly. It has been found when melted that these silver alloys penetrate to every mi croscopic crevice of the metals to be joined together. The joints made are usually stronger than the metals themselves. Silver ia n 1 sn 11 mmrl in fVia mDnnfantn of delicate instruments for a very great variety of scientific purposes. Silver is used as bearing metal in bearings operating without any lubri cants, especially for revolving machin ery used in high-vacuum equipment. The silver bearings are said to possess very smooth running properties and make it possible to dispense with the un desirable evaporation of lubricants which takes place in high vacuum. Silver is also used in making musical and medical instruments. The greater part of all the silver con sumed is made into beautiful sterling sil verware which is used universally in homes, and today more silver than ever before is being used for this purpose. The trade has been stimulated recently by the rising price of silver. Enormous quantities of silver are util ized to making the moving pictures and photographs. A large amount goes into the making of mirrors, and photo-en graving consumes large quantities an nually. Did You Ever Hear a Book Talk?

He suggests in “Flugsport” Die construc tion of a large glider of very light weight and dealt lines. Within the body of this glider there would be place for a man in a reclining position, with his a ted steering handle inside the body of the glider. To fly at minimum power the weight of the man and the glider must be low, the area of the wings so large that the flight is very slow, and the man himself must be a superlative athlete. Scientiflc investigations have shown that a trained runner can achieve 1.4 horsepower for an instant, and average A Ctom • Section Drawing of Man Drh« Aircraft Showing How I h « Propelling Power la Derrl oped by Pedals. a glider could be built weighing only 300 pounds (man included) and with a wing area of 400 square feet, then the minimum power delivered to the propeller, according to the Scientific American, would luive to be 1.04 horsepower. The sjibed of flight would be 24 "■■■■■"■■"■■■■a feet, ner second. This would be pos tulating a very effi cient wing, and practically no re sistance for the rest of the aircraft. John J. Mont gomery was the first American ex It onent of the art of engi ft. Fifty ne pon flying in an less aircraft, ears ago he built s first glider, con feet on bicycle pedals. The pedals would drive an airplane propeller through a chain and sprocket. The man-powered machine would bt. launched into space just like an ordinary glider by rubber shock cord methods. Then the legs of the man would set the propeller in motion and he would be able to stay aloft for a flight of say 1,000 yards. The aircraft would be so designed as to be stable, and the only control nec essary therefore would be the rudder control, effected through a hand-oper wings, each being 10 feet long and four feet, six inches wide. The pair of wings had a total surface of 90 square feet. They were placed tandem fashion and joined by a framework from which a seat was suspended. The wings were curved and arched sidewise like those of * a seagull. The glider was equipped with a hori zontal tail which was elevated or de pressed by means of pulleys. Lateral balance was accomplished by motion in the seat.

The rosebush is first pruned to a proper sue to fit a stand ard container, usually about 15 inches. That portion of the box which is to contain the roots is coated with tar to retain the moisture. Applied at the correct tem perature and with a sufficiently thin coating, ordinary paraffin can preserve an entire season’s growth of choice roses.# AfteT scores of tests it was found that the plants could be success fully treated with hot paraffin at tem peratures ranging from 165 to 180 de grees. Only a fraction of a second is need ed to dip the plants. The hot paraffin does not come in contact with the roots, which are wrapped separate ly in wet peat moss. As a final operation the box is closed and hermetically sealed to form an air-tight container. A Bouquet of Canned Roses Pre served in an Air Tight Container to Withstand Severe Climatic Conditions and Rough Han dling. Clothes Made of Woven Glass “Y^RITTLE as glass” seems to be I—< losing at least a portion of its i- J truth in the light of the cur rent tonnage production of shatter proof glass, glass silk and glass wool. Th® surprising flexibility of the va rious grades of glass fiber is obtained through a combination of filament size, glass batch composition, and manufac turing method. The extent to which these fiber products have been developed is indicated by the character of their glass cotton. The material, as described in the In dustrial Bulletin M Arthur D. Little, closely resembles bulk cotton in physical appearance and “feel.” It is composed of glass fibers, one to two inches long and averaging one ten-thousandth of an inch in diameter. Glass silk is slightly larger in fiber diameter than glass cotton, and differs from both glass cotton and glass wool in its mass form, which in turn results from the method of production. Both the latter are made as a loose tow in which the fibers are at most only a few inches long, and are much interlaced in at least two directions. Glass silk is produced as a series of parallel fibers of practically continuous lengths. In this condition it may readily be worked by the long-fiber textile proc esses, and converted to yarns and fab rics. Glass wool is available in a closely controlled range of sizes, from fine wool of approximately five ten-thousandths inches in diameter to a comparatively coarse fiber 10 to 15 times this size. The finer grades are used at present largely for heat insulation. In that structural field glass wool is completely fire-and-vermin-proof, while the resil iency and length of the glass fibers prac tically eliminate the tendency to settle and leave open spots at the top of the m insulated space as so frequently occurs * with short-flbered mineral wools, espe cially where vibration is present. Acous tically the insulating value of this ma terial is excellent. Studying Diseases by Cold ELECTRIC refrigerators are being used in a study of physiological adaption to cold, which is expect ed to give some information on the anemias. Doctor Ira A. Manville has recently completed a study of the effect of rare fied atmosphere on the blood count in red corpuscles and hemoglobin. These studies were made through a medium of rats subjected to various diets and given an exposure to rarefied atmospheres, ap proximating eighteen to twenty thou sand feet above sea level, as reproduced in a decompression chamber which Doc tor Manville developed for the purpose. nPtw* oofs av* nlo^ad in on The refrigerator being used by Doc tor Manville in these experiments has a special glass door so that the doctor can observe the reactions of the rats during the experiments and an accurate record of temperatures in the cold compart ment can be kept. Doctor Manville's experiments are ex pected to contribute more information about the conditions regulating the pro duction of red corpuscles and hemoglo bin and may be of value in the treat ment of various anemias. As a result of his tests Doctor Manville hopes to de velop a new method. electric refrigerator under various temperatures and are exposed for periods of ap proximately four to six hours. Incidentally, the data re sulting from these experi ments may provide reasons for believing that victims of pernicious anemia die liter ally by freezing to death. The low body temperatures de veloped in this manner cause a paralysis of the nervous func tions that results in death.
