FUR-SEAL CENSUS, PRIBILOF ISLANDS, 1920. 



By G. Dallas Hanna. 



I landed at the Pribilof Islands on June 16, 1920, from the U. S. 

 naval radio tender Saturn for the purpose of making a census 

 of the Alaska fur-seal herd which resorts there to breed. In order 

 to complete the work it was necessary at various times to travel 

 from St. Paul Island to St. George. Island and vice versa. This 

 "was effected through the courtesy of the commanding officers of the 

 Saturn, the Coast Guard cutter Alf/onquin., and the Bureau of 

 Fisheries vessel Eider, to all of whom my appreciation is extended. 



The census was made possible through the active cooperation of 

 the superintendent of the Pribilof Islands, A. H. Proctor, in fur- 

 nishing material and labor on St. Paul Island when necessary. C. E, 

 Crompton, agent and caretaker, did likewise on St. George Island. 

 E. C. Johnston, storekeeper on St. George Island, ably assisted in 

 the actual census work as much as possible. 



The methods used in counting and computing the various classes 

 as given below were similar to those which have been in use for 

 several years and which were outlined in the report of the Alaska 

 Fisheries and Fur Industries in 1918, page 116.
