Cool Droplets. In Scientific American, Cloud Physicist B. J. Mason of London's Imperial College of Science and Technology tells of experiments made to determine why some clouds give rain while others float high in the air until they evaporate. When he carefully cooled small droplets of very pure water, they did not turn to ice until the temperature fell below - 42° F. This proved, as had been suspected, that ice crystals seldom, if ever, form in moderately cold clouds unless some solid nucleus is present to start the process...
...Mason's next step was to cool droplets containing microscopic nuclei made of substances that are common in powder-fine dust blown up from the earth's surface. A few kinds proved almost as effective as silver iodide smoke, but most required very low temperatures before they could turn cold clouds into snow...
Trained Dust. In further experiments, Mason showed that some kinds of common natural dust can be "trained" to collect ice. Particles of kaolinite (common in clays) do not act as ice-forming nuclei above 16° F., which is colder than the tops of many clouds. But when kaolinite particles have once had ice crystals on them, and when this ice has evaporated, they are able to form fresh crystals in clouds no colder than...
...only a third-stringer on the All-America teams of the A.P. and U.P.I., but Tulane's Halfback Tommy Mason (6 ft. 1 in., 195 lbs.) had the speed and strength to make the first team of the pro scouts' All-America (TIME, Dec. 12). Last week he was tapped by the newly formed Minnesota Vikings to become the first man chosen in the annual draft of college stars by the National Football League. Second man picked: Wake Forest's Norm Snead, a king-size (6 ft. 4 in., 208 lbs.) quarterback, who was picked...
...once again practically the private preserve of gunslingers. Although NBC's Wagon Train topped the sorry heap with a 36.9 Nielsen, CBS grabbed off seven of the next nine places, with Gunsmoke, Have Gun, Will Travel, a Red Skelton special, Dennis the Menace, Rawhide, Andy Griffith and Perry Mason. The only challengers: ABC's The Untouchables and 77 Sunset Strip, in fifth and sixth positions...
