...twin births are declining, reported Obstetrician Alan F. Guttmacher, of Manhattan's Mt. Sinai Hospital, in Obstetrics and Gynecology. Until 1939, one out of every 86 births in the U.S. was a twosome. By 1949, the U.S. twin rate had dropped to one in 97, and the ratio is going farther down. Dr. Guttmacher, an identical twin, believes there are some undiscovered biological or environmental factors affecting the glands of U.S. mothers...
...some products. There was a potential danger signal in business inventories, which rose to $77.3 billion at the end of June, $4.8 billion higher than a year ago. But there was a balance wheel in the fact that sales were up $5.3 billion above last June. That left the ratio of sales to inventory unchanged...
...supersonic aircraft, while all De Havilland's previous jets (e.g., the Goblin, which powers the Vampire fighter, and the Ghost, which powers the Comet and the Venom fighter), have been centrifugal types.* De Havilland said that the engine, which has low gas consumption and a low ratio of weight to thrust, is being developed first for supersonic fighter planes, later could be built for transports.

There were some pessimistic figures. Inventories reached a record $78 billion, up $4 billion from a year ago. And though the Commerce Department saw nothing to worry about, since the ratio of sales to inventories was the same as last year, many a businessman was not so sure.

Farm income was on the way down, and sales of farm equipment were slipping. Nevertheless, most businessmen were optimistic about...
Last week the first mass-produced TR-2 came off the assembly line. Short (12 ft. 4 in.) and low (3 ft. 10 in. to the top of the windshield), it has a four-cylinder, 90-h.p. engine with two carburetors and 8.5 to 1 compression ratio. The TR-2 gets 24 miles to the gallon, has independent front-wheel suspension for easier riding and two bucket seats. A particular attraction for sports-car buyers: the jetlike scream produced at high speed by the air scoop in front. The TR-2 will go on sale in the U.S. early...
