98 FISHERY AND FUE INDUSTEIES OF ALASKA IN" 1912. 



killed between August 10, 1911, and August 11, 1912) and allowing 

 a natural mortality of 14,500 (which is excessive in the absence of 

 pelagic sealing), we arrive at the 48,000 of Mr. Clark's estimate. 



It therefore seems certain that the Alaska fur-seal herd at the 

 end of the killing season of 1912 (August 10) numbered at least 

 215,940 seals of all ages, and the proportion of seals of the various 

 classes shows it to be in an excellent condition.
