ANNUAL REPORTS OF DEPARTMENT OE AGRICULTURE. 



ment of relatively small projects is particularly in evidence in the 

 Rocky Mountain States. A decrease of 356,603 horsepower in the 

 estimated capacity of all projects under permit was due mainly to 

 the elimination from the Dixie National Forest of the land upon 

 which is located a project of very large capacity, and in lesser measure 

 to revised estimates of capacity and to the revocation of some per- 

 mits for failure to comply with the conditions prescribed. 



An apparent decrease of 76,183 horsepower in the capacity of 

 plants in operation was due to a change in classification of a permit 

 covering four projects, of which two are in operation, one is under 

 construction, and one is not yet started. These four projects are 

 in this statement placed each in its proper class, but in the 1915 

 statement were counted as one. 



In the amount of power under permit and in operation, California 

 still leads. 



Of transmission-line permits the number in effect at the end of 

 the year was an increase of 13 over the number one year previously. 



The 40 applications for power-project permits shown in Table 11 

 as received during the year included 8 from Alaska — a notable evi- 

 dence of increased local interest in power development on the Na- 

 tional Forest lands there. 



Permits are classified according to the character of the works 

 covered. Permits for transmission lines only are designated "trans- 

 mission-line permits," while those which cover reservoirs, conduits, 

 or power houses, irrespective of whether or not a transmission line 

 is involved, are designated "power-project permits." Table 10 

 shows the amount of development authorized under both classes.
