1 The few cows reported above, about one-third of 1 per cent of the total take, were accidentally and 
unavoidably killed. Every possible effort is made to avoid the killing of cows, but persons familiar with 
conditions at theislands willreadily appreciate that oncein a great while a cow is killed. 
BRANDED SEALS, 
Fifteen 8-year-old male seals, bearing the brand placed upon them 
as pups in 1912, were killed during the calendar year 1920. Of this 
auanber six were taken on St. Paul Island and nine on St. George 
sland. 
It is from the 1912 series of branded seals that the data were ob- 
tained from which the age classification standards now in use were 
developed. Observations have also been made as to the develop- 
ment and movements of female seals bearing the 1912 brand. It is 
believed that more dependable information has been obtained as a 
result of the branding done in 1912 than from any similar work done 
in the past. 
The following table shows certain information secured from the 
animals killed this season :
