The seals branded when pups in 1912 continue to furnish valuable 
information along lines which require that animals whose ages are 
definitely known shall be available. 
On St. George Island in the period from June 9 to August 10, 1916, 
both dates inclusive, there were observed in various drives 198 male 
seals bearing the 1912 brand. Of these 30 were killed. In order 
that no branded seal might be counted more than once each one of 
those not killed was when first counted marked by clipping the 
hair and fur from the left side of the head. When one of these 
clipped seals appeared in a subsequent drive, a record was made of 
a Bureau of Fisheries document No. 834, p. 96.
