...themselves-a French provincial-chateau-style affair in Locust Valley, L.I., right next to a golf course. They sublet it for two months. Up from the South, they moved in, then packed their bags for a week in Washington and a houseparty with Railroader Robert R. Young at White Sulphur Springs, W.Va...
Steel manufacturers know that sulphur (an undesirable impurity) gets into steel from the coal used as fuel. But there are two types of sulphur in coal: organic and "pyritic" (iron sulphide). Republic Steel Corp. wanted to know whether either type is driven off when the coal is made into coke. There was no handy chemical way to find out, but the Little Co.'s scientists worked out a tracer technique that did the job quickly and easily...
They made a small amount of pyrites containing radioactive sulphur and mixed it with a coke-oven charge of coal. They roasted the coal and measured the radioactivity of the sulphur remaining in the coke. A very low level of radioactivity would indicate that most of the pyritic sulphur had been driven off, taking with it the radioactive tags. A higher level would show that the organic sulphur had been eliminated, leaving behind the pyritic sulphur. Actually, the radioactivity of the sulphur fell between the two extremes, showing that both forms of sulphur stay behind in the coke. The experiment...
...almost a masterpiece. Particularly in its early chapters (the later ones grow somewhat confused with the ramifications of the feud), it summons up the life of the mountains in the days before the fighting began: little streams, dropping 25 feet to the mile, with names like Grapevine, Blackberry, Sulphur, Sycamore, Turkey and Buffalo; old families of English stock bearing names like Vance, Chafin, Smith, Weddington, Varney, Cline and Trent; forests of oak, cherry, walnut, hickory, linden, beech, sycamore; cabins with quiet hospitality, plenty of food, and courteous, high-strung, honest and proud people...
...Dyer of the U.S. Public Health Service tags penicillin molecules with radioactive sulphur, then traces the drug through the human body to find out just where it goes and what eventually happens...
