Consequently it may be estimated that the number of 3-year-old seals 
taken in the kill represents 1,243-l114= 91 percent of the total that hanled 
out on land before July 27, 1224 
Method 2, Comparison of tag recoveries and the total kill: This 
comparison would be similar to Method 1, if the number of 3-year-olds in 
the kil] were known for each size class. What is known is the estimated 
total number of 3-year-olds in the 1950 kill (31,746 from table 30) and the 
fact that most of the seals below 41 inches in length, in the commercial kill 
are 3-year-olds, It is also necessary to use the estimate of oversize escape- 
ment of method 1: 10 = .67 of this group apparently escape through the kill.

With these assumptions, the procedure is as follows:
