Figure l.--The motor vessel "Chugach" was used throughout 

 the survey of Southeast Alaska. 



Basic resource data were assembled from aerial photos and ground 

 samples on an area of about 3-1/3 million acres of commercial forest 

 land during the biennium 1956-1957. Compilation of the basic data 

 was increased in efficiency and speed of operation by a complete 

 conversion to the IBM system. A coding scheme was set up in 1956 

 in cooperation with the California Forest and Range Experiment 

 Station and a compilation plan has been written and approved. The 

 IBM Unit at the California Station will provide the tabulations as 

 needed.
