COMPUTATION OF FUR-SEAL HERD 



The computation of the size of the fur-seal herd in 1930 was again 

 made by Supt. H. J. Christoffers, who was assisted by A. Christoffer- 

 sen, A. J. Messner, and C. M. Hoverson. As of August 10 the total 

 of all classes was 1,045,101 — a numerical increase of 73,574 and a 

 percentage increase of 7.57 over the figures for the preceding year. 

 The detailed report will be found on pages 100 to 108 of this document. 

 Following is a comparative statement of the numerical strength of 

 the various elements of the fur-seal herd in the years 1919 to 1930, 

 inclusive.
