Estimated number of harem and idle bulls, approximate ratio of idle bulls to harem 

 bulls, and average harem, 1935 



AVERAGE HAREM 



The only way to determine whether sufficient bulls have been re- 

 served is to ascertain the average harem and make observations as 

 to whether there are sufficient young bulls to take care of the late- 

 arriving 2-year-old females. The ideal average harem is considered 

 to be from 40 to 45 females. 



The estimated average harem in 1935 for St. Paul Island was 42.14 

 and for St. George Island 42.74. This is an increase of 0.46 over the 

 preceding year for St. Paul Island and a decrease of 0.41 for St. 

 George Island. The average harem, as estimated, would indicate 

 that sufficient males have been reserved for breeding requirements.
