Lakes Dyed Black To Curb Weeds In Arizona Study
Arizona Game and Fish Commission researcher George Eicher reports that dumping black aniline dye into four small lakes in Granite Basin and Ashugust reduced weed growth and dropped water temperatures by up to ten degrees at 15 feet. The method shows promise for small ponds but is costly for larger waters and warrants further study.

Underground Coaxial Cables Replace Overhead Telephone Lines
Underground coaxial cables are replacing cross country overhead lines, enabling 1800 conversations and TV transmission. Invented 16 years ago, they reached demo by 1943 with 1500 miles in use, rising to about 7000 by end of 1949. The first transcontinental route runs New York to Los Angeles via Washington, Atlanta, Dallas and El Paso, with Mickey Mouse plows burying the cables four to five feet deep.
