If he can stay at the shoulders of Wykoff his chances of winning will be extraordinarily good. Simpeon himself is not without hope.

But it has been said that if a man will stick long enough luck will always change, Possibly Simpson will have his great day in Pittsburgh and beat his old rivals in the national 100 yards. But whether he wins or not, George is sure to prove himself a true sportsman. Though fate has stacked the cards against him on several occasions, he has never whimpered or alibied, taking each blow squarely on the c¢hin and coming back for meore. HE favorite of the field at Pittsburgh, how- ever, will be Frankie Wykoff of the Los Angeles Athletic Club. As a sophomore last Bpring this fleet young Trojan won the Pacific Coast, intercollegiate and national collegiate championships. He lost only one race during the college season, and that to a man whom he Jater defeated—Hector Dyer of Stanford University. On the occasion of this defeat Dyer got off to a marvelous start. Wykoff tried so hard to catch the other man that he tled himself in knots and did not Jook at all like a ehampion. I saw that race and later in the season, after watching S8impson run, it was my opinion that the Ohio State man would defeat Wykoff. But Plying Frank not. only beat Simpson—he ran the hundred without starting blocks in 9 2-5 meconds, the fastest official time ever made. Early in the year, during the Southern Cali- fornia Amateur Athletic Union championships, e had established these same record-breaking figures, His coach, Dean Cromwell, sincerely believes that Wykoff will run the hundred in ® 1-5 seconds before he is through. Though the old-timers lift their eyebrows at such pre- diction, they did the same thing a few years ago when 9 2-5 seconds was suggested as a pos- , wibility. Wykoff, when he is right, seems to possess everything. He proved this in the 1928 Olympic tryouts at Boston, when he won the hundred meters from the greatest field ever assembled. On that day he ran this distance four times in 10 3-5 seconds, equaling the Olympic record. ‘Wykoff then was still a high school boy. It was !cnbquyfinthehtdburnedhmuwl. Later performances in the Olympic games justified this opinion, for at no time was he himself. The following year a throat operation seemed to rob him of his vitality and he never approached what he had accomplished in 1928. This year has been a different story, and his record installs him as the favorite for the hun- @red. In all probability he will not compete in the 220. ‘Though not a big man, Wykof! seems quite %all enough, and already has developed an eight-foot stride, which is considerably longer than that of the majority of sprinters. He is & good starter—as good as the game has pro- duced—but his phenomenal speed les in his ability 1o pick up between 10 and 40 yards. That is where he wins his races, He seems almost deliberate as he comes out of his holes, gradually gathering himself fog the tremendous burst of speed he applies before he has reached the half-way mark. This great momentum throws him into his long, easy stride, ahead of the field. Al that he has to do from then on 'THE SUNDAY STAR, WASHINGTON, D. €. AUGUST 17, 1030.

It was first time in nine years that 14 2-5 seconds had been made in this event. Anderson is a great competitive athlete and the actual clearance of the hurdles effortless. Though Anderson should win, Sentman, Rock- away of Obio State and Jeddy Welsh of the Los Angeles Athletic Club will turn. this event into a real battle. Bob Maxwell, also of the Los Angeles Athletic Club, is a menace for Anderson in the low hurdles, Though other duels on the track may mnot prove quite so thrilling as those just mentioned, there will be plenty of fireworks in the field events. Leading the list again will be Patrick MacDonald and Matt McGrath, high ranking members of New York's. “Finest,” ,who have been representing the city in national cham- pionships ever since “little old New York” was just that.

It is estimated that the United States alone can turn out from 400,000 to 450,000 pounds annually, as by-preducts or other indusiries. The real growth of the selenium industry began in 1922, when 123,000 pounds were produced. It has gained each year, and 1927, the last year for which complete figures are available, showed 284,500 pounds used. The rubber industry seems to offer the largest use at present, and it is believed that re- search will add greatly to its employment in that line. Selenium in metallic foom has long been characterined by its unique action toward light. Its conductivity of an eleciric current varies so greatly when brought from the The selenium cell has received considerable attention for many years. Its action toward light and the resulting effect upon its re- apparatus for chimney vehicular tube of progress in The selenium cell, however, can be used oniy where the recovery of its absolute re- sistance to change from light to dark does not have to be instantaneous. Where this change must be instantaneous other cells, such as the potassium photoelectric cell, or .the copper oxide cell, are used. During recent years selenium cells have been considerably improved and several makes are now on the market, where the inertia has been reduced to a minimum. The pessibility of using selenium cells for television purposes is again being investigated. Another unusual use of selenium is that for flameproofing electric switchboard cables. The cables behind the switchboards of generating and distributing stations are apt to accumu- late dust, and this occasionally produces short circuits, which, when heavy currents are car- ried, may set fire to parts of the cable cove ering. Cables treated with a thin layer of metallie selenium, however, are made flame- proof to a remarkable extent. The prineipal use of selenium and its ecom- pounds at present is ds a decolorizer in the glass industry and for the production of ruby glass (sailing signals, auto tail-lights, railroad signal lights, etc) and ruby giazes in the ceramic ' industry. Its principal use in the glass industry is to offset the greenish tint which is caused by traces of iron in the glass sand. . In' the manufacture of ruby glass selenium is used extemsively, either in the form of the element or as the selenite in conjunction with a reducing agent, such as arsenious oxide. Red lead and gold chioride, however, also are used for the same purpose. Another use for selenium which may be- come of importance is as a solvent. It has been stated that selenium in the form of selenium oxychloride is one of the most pow- erful solvents known: Synthetic phenelic resins, such as redmanol or bakelite, which are used for many industrial purposes and have hitherto been regarded as totally in- soluble, are now readily dissolved by selenium oxychloride. Considerable research work has been ear- ried on concerning the use of selenium as a vulcanizing and acctelerating agent in the manufacture of rubber, The use of this min- eral in the rubber industry is increasing, and it is estimated that in 1929 about 100,000 pounds of selenium were used in that work. The potential demand for selenium, if its use is adopted by the entire rubber industry, is far greater than .the copper reflneries can «- furnish. Fine-drawn wire of selenium. made by the Taylor process is finding some commercial applications, This wire may be drawn to diameters as small as one milimeter to ome micron. Selenjum, although fairly widely distributed, is not very abundant in nature. It is found associated with its sister element, sulphur. ‘The sulphides of the heavy metals likewise are often accompanied by selenium and tellurium, presumably in the form of selenides and tellurides. Certain iron pyrites, such as that from Greece, Spain, Germany, and from the Scandinavian Peninsula, contain some selenium. Both the German and the Scandi- navian pyrites yleld selenium. The selenium is not, of course, the object of the metal- lurgical operations, but it is recovered come mercially with nickel and molygdenum as by=- products from the smelting operations, which have as their main object the production of copper and of sulpluric acid. Selenium has been found in meteoric iron and in the mineral water from La Roche-Posay.
