...made carefully detailed plans to keep order. Orval Faubus never gave the mayor's plans a chance-and Woodrow Wilson Mann, who had twice supported Faubus for governor, is eloquent in his anger. Says he of Faubus: "His words spell sedition, his defiance rebellion. His words and actions echo another tragic period in our history when irresponsible men plunged this nation into a Civil...
...track in a single night, the train sometimes has to turn back despite all precautions. And so far, French attempts to ambush the guerrillas a-t work have been generally unsuccessful. Disappointing, too, is the radar system which the French set up to catch the guerrillas' movements. "The echo is fine against the rebels," said a French officer last week.

Heretofore, the usual method of improving reception has been the brute-force approach of multiplying the power of the signal. But this multiplication requires costly and cumbersome equipment, is impractical for such isolated sites as the arctic...
