"Fifteen Radio Stations to Improve Air Mail Service.

By S. R. Winters

THE POST OFFICE Department has established a transcontinental communication system consisting of 15 radio stations built at a cost of $26,000. Operating as an adjunct to the air mail service this radio system will be used to secure information as to inter-station traffic, furnish meteorological data and facilitate transcontinental relays from Washington.

The use of 65 airplanes in the transportation of 200,000 first-class letters daily, and embracing a mileage of 6,980, suggests the magnitude of the coast-to-coast air route, involving the use of wireless. Ten of the fifteen radio stations interlocked with an equal numkber of flying fields, which are maintained to relieve the railways of their postal burdens. Army and Navy wireless stations are used where practicable, which policy avoids duplication of construction and eliminates working interference. These stations are located in Dayton, Cleveland, Chicago, San Francisco and Sacramento."
