106 SEAL LIFE ON THE PRIBILOF ISLANDS. 
We have then to find out how many new individuals were among 
the seals rejected from the subsequent drives. The proportion rejected 
from the first drive from Northeast Point was estimated as 45 per cent; 
from the second drive, 60 per cent and 65 per cent, or an average of 62.5 
per cent; from the third drive, 73 per cent. The increase in the second 
and third drives is 17.5 and 28 per cent, respectively. These percent- 
ages we may take to be those of the new individuals. 
We may make up the total, therefore, in the following manner:

This may be taken as the number of seals on the hauling ground dur- 
ing the six weeks. Treating the other hauling grounds in the same 
manner, we have the following amounts:

This, it will be observed, is consider ably less than the number driven, 
viz, 28,970, but it represents, in my opinion, much more nearly the cor- 
rect number of seals present on the hauling ground during the period. 
This total, 21,049, is based on the assumption that all the bachelors 
have arrived by August 1. But as at the last killing, on that date, 
about 20 per cent of “killable seals were still obtainable from the num- 
ber driven up, it would appear that if killings were made later (at 
least up to the end of August) a small number of new seals would be 
obtained. 
I calculate that this would not exceed 2,000 seals for all the hauling 
grounds. Adding this to the total previously obtained, we have 23,049 
for the whole number of bachelor seals on the hauling grounds during 
the season. This includes only the grounds from which drives were 
made, and we have yet to consider the grounds at Ketavie and the 
Lagoon, which were not disturbed; also the areas back of the breeding 
grounds and the fringe at the water’s edge. For the Ketavie hauling 
ground I estimate from my observations that the number should be 
about 500, for the Lagoon hauling ground 400. 
For the areas back of the breeding grounds and the water front no 
reliable estimate can be made. These bachelors are constantly moving 
about, and were also more or less disturbed in some places this season, 
at least by persons passing to and fro. The bachelors at the water’s 
edge doubtless go to the terminal hauling grounds, and may perhaps 
sately be regarded as already estimated for. 
If one-tenth were added for these scattered bands of bachelors, it 
would probably be sufficient; but this is a purely nominal estimate. 
To recapitulate, the total is made up as follows:
