1277. Anonymous. Fliegertatigkeit im Dienste des Forstschutzes. [The use of air planes 

 In forest protection.] Schweiz. Zeitschr. Forstw. 71 : 82-83. 2 pi. 1920. — Photographs taken 

 from airplanes may be used for classification of areas in suitable regions for grazing, etc., also 

 for topographic features and boundary locations of permanent forest areas. Photographs 

 taken on a scale 1:25,000 bring out a great deal of detail. Often aerial patrol may bring out 

 features that would be lost otherwise, such as snowslides and landslides in the initial stages. 

 Taken in time, these may be prevented. — J. V. Hofmann.
