Abstract
THE progress which is being made in longdistance telephony is exemplified in the interesting- demonstration last week under the direction of Col. Cartj in which conversations were carried on over a composite route of more than 5500 miles made up of a 115-mile section of submarine cable from Havana to Key West, overhead lines through Washington and New York, and right across the continent through San Francisco to Los Angeles, and, for the sake of completeness, including a 2g-mile stretch of “wireless” to St. Catalina Island, in the Pacific.
