CHARTING AIR LANES.
Mosaic of United States Showing Landmarks to Follow.
Special to The New York Times.
WASHINGTON, Nov. 10.—Charting air lanes over the United States has been begun by the army. These charts are mosaics made with stereopticon cameras, showing such land marks as waterways, railroads, cities, and mountains for pilots to follow.
From Kelly Field instructors and members of their classes work with the aid of airplanes carrying cameras and motor trucks carrying photographic material and supplies and a portable darkroom for developing plates and films. Sich an outfit is usually set up in some town in the district to be photographed, which has a landing field adjacent. The men employed in the work are rationed from this camp, and the developing and printing of the films and plates delivered by the airplanes are all done here. As fast as one district is finished the outfit moves on to the next.
