FUR-SE =NSUS, PRIBILOF ISLANDS, 1920. 
By G. Dattas 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 Algonquin, and the Bureau of 
Fisheries vessel Hider, 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 hkewise 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.
