COMPUTATION OF FUR-SEAL HERD 



A continued satisfactory growth in the size of the Pribilof Islands 

 fur-seal herd was shown in 1929. As of August 10 the total of all 

 classes was 971,527 — a numerical increase of 100,014 and a percentage 

 increase of 11.48 over the figures for the preceding year. The com- 

 putation was again made by Supt. H. J. Christoffers, who was assisted 

 by A. Christoffersen, H. A. Peterson, and A. J. Messner. The detailed 

 report will be found on pages 334 to 339 of this document. Following 

 is a comparative statement of the numerical strength of the various 

 elements of the fur-seal herd in the years 1918 to 1929, inclusive:
