ALASKA FISHERY AND FUR-SEAL INDUSTRIES, 1924 



165 



Distribution of pups on the Pribilof Islands, August 10, 1924, and comparison loith 



distribution in 1923 



1 Actual count. 



As sho^vTl in the above table, the pups on St. George Island 

 increased 26.76 per cent while the number on St. Paul Island increased 

 only 1.9 per cent. The rookeries on the north and east sides of St. 

 Paul Island actually showed a decrease. The only rookerv on St. 

 George Island to show a decrease was South rookery, which had 

 23 pups less than was estimated for it in 1923. As the number of 

 dead pups found during the count was approximately the same as 

 in 1921, the same percentage was assigned to the other rookeries. 



COWS 



Since the number of cows, for census purjjoses, is the same as 

 the total number of pups, the figures above will apply to the adult 

 females. On St. George Island there were 35,868 cows and on 

 St. Paul Island 172,528, a total of 208,396. 



No cows bearing the single bar or brand across the back were 

 seen in 1924. If any are alive the number is probably small. They 

 were branded in 1902 and 1903. 



Twelve dead cows were found on the rookeries where pups were 

 counted. This is 0.06 per cent dead, and, applied to the whole 

 herd, the number would be 125, or about the number normally 

 found.
