ALASKA FISHERY AND FUR-SEAL INDUSTRIES, 1925 



149 



On St. George Island, operations began on June 16 and ended on 

 July 22. During this period 1,930 3-year-olds, 642 4-year-olds, and 

 518 5-year-olds were marked. 



The breeding reserve was increased only by the number of 3-year- 

 olds marked. The other seals were marked only in order that data 

 in regard to the return of older animals might be obtained. 



On St. George Island, 800 3-year-olds were branded with a hot iron 

 in order to secure data later. The other 14,202 animals were marked 

 by shearing a patch of fur. 



Further details in regard to the reserving operations are shown in 

 the following table :
