building has a concrete base with upper structure of wood. In addi- 

 tion to the new combined pump and engine there w^s installed in 

 this building the pumping equipment previously used, namely, one 

 combined pump and engine and one centrifugal pump, together 

 with the 10-horsei3ower engine for operating it. The intake pipes 

 for all three pumps were led to a corner of the wharf at the village 

 landing. 



In the washhouse the number of wooden tanks in which sealskins 

 are washed and cooled was increased to 12. A better method of 

 draining used water from the building was also devised and the 

 necessary changes made for putting it into effect. Subsequent to the 

 sealing season of 1922 a 50-foot extension -was added to the wash- 

 house. The building now has ground dimensions of 42 feet by 120 

 feet. 



On St. George Island building operations for extending the wash- 

 ing and blubbering operations to that island were begun and car- 

 ried well along toward completion. 



CENSUS 



In 1923 the census of the Pribilof Islands fur-seal herd was taken 

 by Edward C. Johnston. His report is printed in full on pages 135 

 to 140. The following is a comparative statement of the numerical 

 strength of the various elements of the herd in the years 1912 to 

 1923, inclusive.
