ANNUAL INCREASE OF THE FUR-SEAL HERD. 



The increase in the total number of seals in 1922 over 1921 was 

 23,519, or 4.04 per cent, as compared with an increase of 28,725, or 

 6.2 per cent, in 1921 over 1920. 



The minimum reserve of 5,000 three-year-old males for breeding 

 purposes as required by law will be wholly inadequate in the future 

 for the proper upbuilding of the fur-seal herd. Not less than 10,000 

 seals of this class must be reserved annually in order to provide 

 sufficient male strength. 



COMPLETE CENSUS. 



The figures given below are as nearly correct as it has been possible 

 to make them. They are based upon a complete pup count on all 

 rookeries, a harem count in which 11 elevated counting stations were 

 used, and a close approximation of the numbers of those classes of 

 seals that can not be counted. The seal herd shows a satisfactory 

 growth, although the decrease in number of breeding bulls and the 

 increase of average harem should be corrected as soon as possible. 

 This can be done, of course, by reserving a large number of 3-year-old 

 males.
