in charge of harems; but it is very probable that the actual number 
of 6-year-old harem bulls was more than large enough to make up 
for the increase. <A total of 4,034 harem bulls was counted. The 
number in 1925 was 3,526. 
The number of idle bulls increased from 283 on St. Paul Island 
in 1925 to 368 in 1926, and from 28 on St. George Island in 1925 
to 55 in 1926, a total increase for both islands of 112. The approx- 
imate ratio of idle bulls to harem bulls was 1 to 11 for St. Paul 
Island in 1925 and 1 to 9 in 1926; 1 to 15 for St. George Island in 
1925 and 1 to 10 in 1926. The approximate ratio for both islands 
was 1 to 11 in 1925 and 1 to 10 in 1926. It will be noted that each 
comparison shows a trend toward a more favorable ratio of idle to 
harem bulls. ; 
Four dead bulls were observed during the progress of the work. 
SIX-YEAR-OLD BULLS 
A count was made of bulls iron-branded as 3-year-olds in 1923, 
and also of bulls of the same size but not branded. On St. Paul 
Island 73 branded animals maintained harems and on St. George 
Island 29, a total of 102 6-year-olds. On St. Paul Island there 
were 202 harem bulls that appeared to be 6 years old, and on St. 
George Island 110, a total of 312 unmarked 6-year-olds. A total of 
414, or about 10 per cent of the harem bulls, were 6 years old. 
In 1925 only seven bulls that appeared to be 6 years old were 
found. There probably were many more, and the low estimate was 
caused by the fact that there was no standard by which to judge 
whether an animal was 6 years old or not. In 1926 there was a suffi- 
cient number of animals known to be 6 years old, to which unmarked 
bulls could be compared.
