...tall, tanned geophysicist and petroleum engineer named Herbert Clark Hoover Jr. addressed the Institute of Radio Engineers in San Francisco. He told them how seismographic or "artificial earthquake" methods of prospecting for oil had improved in recent years. Technique at present is to bore a hole 500 ft. deep, drop a dynamite charge to the bottom. When the charge is exploded, vibrations resembling earthquake waves ripple out in all directions. Some travel straight down, and part of them are reflected back up with different intensities from layers of rock, sandstone, limestone, shale. Geophones on the surface pick up these reflected...
...forests are mostly in the Highlands. At least 2,000,000 acres of the lands are so high and rocky that they could never be farmed. They are not, however, wholly unproductive. As private parks they are heavily taxed, and when the hunting season is on thousands of sportsmen drop thousands of pounds into the coffers of thrifty Scottish tradesmen. To shoot Scottish deer (and grouse) huntsmen spend some $3,500,000 annually in Scotland...
...hills on the coast of Indo-China drop steeply to the sea, continue their sharp decline beneath the surface, so that the water where the Phenix disappeared is 365 to 375 feet deep. Built to stand pressures down to 330 feet, the hull of the submarine probably collapsed when it plunged to the bottom. Persistent oil slicks on the surface confirmed this theory. France, which possesses no escape bells of the type used in the Squalus rescue, had just opened negotiations with the U. S. for the purchase of four, but even if one had been available it would have...
...hands out. His men admire him, too, for insisting that the paper run the story of his income tax troubles (TIME, May 1) on the front page. Advertisers think the Inquirer's, circulation has been inflated by $12 clocks given with ($4) subscriptions, believe it will eventually drop back to about 300,000 daily and 500,000 Sunday. (Present Sunday circulation is 1,000,000, but nearly half of that is "jackrabbit," a predated edition circulated from Maine to California-Peoria, Ill. accounts for 5,000 copies-and distributed by newsdealers who make huge profits selling Annenberg racing sheets...
...finished. Cinemactress O'Sullivan undertook the role three and a half months before her child was expected, finished the job with only a month to spare. Cameraman Leonard Smith shot Miss O'Sullivan behind fern fronds, through leafy screens, at respectful distances, permitted his camera to drop no hint of her own infanticipation...
