Returning Echoes. The heart of Ross's compact (150 Ib.) machine is a crystal of Rochelle salt† that converts electrical energy into pulses of "ultrasonic sound" (unlike radar, which uses radio frequencies). Focused into a narrow beam, the sound pulses are shot out through an underwater transmitter that can turn through 360°. Echoes from underwater objects come back to the transmitter and are displayed on one cathode-ray screen as part of a glowing map that measures distance and direction from the ship. Moving targets can be tracked across the scope as on an ordinary radar screen...
...Utah's Bonneville Salt Flats, veteran Racing Driver Ab Jenkins warmed up his old Mormon Meteor, which has carried him to world records at every distance from 50 kilometers (at 172.92 m.p.h.) to 1,000 miles (at 172.8 m.p.h.), for a last fling at some new records. On the twelfth lap around the twelve-mile course, hitting 200 m.p.h., the Meteor skidded and mowed down a line of wooden markers before Jenkins could straighten out. As the car began to heat up and smoke, because of a punctured radiator hose line, Jenkins braked to a stop and jumped...
...Angeles, and this could be used in Arizona. Part of it might be diverted from a Colorado tributary, the San Juan, and turned into the Rio Grande watershed for desperately water-short New Mexico. It might be exported to eastern Colorado, or to the Bonneville Basin around Great Salt Lake, where the growing industries of Utah are screaming for water. Thus the abundant flow of the Klamath could bring new life to dry lands more than 1,000 miles away...
...water almost everywhere. It does not exist as "veins" but in saturated sand or gravel called the "water table." Certain special conditions, such as sand so fine that it cannot be filtered, or hard rock near the surface, make well-digging undesirable. A dowser who is worth his salt can avoid such hostile spots without magical assistance. Anywhere else, he is almost sure to find at least a little water...
Ever since Texas Gulf Sulphur Co. developed its first producing well in a Gulf Coast salt dome 33 years ago, Walter Hull Aldridge has been its boss. Under Aldridge, Texas Gulf became the world's biggest producer of sulphur (second: Freeport Sulphur Co.) and the largest source of the cheap, pure sulphur (i.e., brimstone) needed by thousands of industries. Last week Walter Aldridge, 83, resigned as president of Texas Gulf and stepped up to be board chairman...
