a Estimated. 



The total number, 28,970, whicli represents quite accurately the num- 

 ber of seals driven from the hauling grounds during the season, would 

 also rei)resent the number of individual seals on those grounds during 

 June and July, did not the rejected ones return to their place. As it is 

 known, however, that many do so return — and may be considered prob- 

 able that all those rejected return to one or other of the grounds — it is 

 evident that in this total some seals are counted twice or three times. 

 To find the correct total it will be necessary to make a reduction for 

 those seals which appear in the drives more than once, and this is a most 

 difiicult matter on account of the complexity of the problem. Some 

 facts indicated in the foregoing table are of interest in this connection. 



It will be observed that the number of seals on each of the rookeries 

 is practically the same at different parts of the season. This agrees 

 with what appears to the eye to be true; that is, in a short time after 

 the bachelors have been driven from a hauling ground there appear to 

 be as many seals present again as there were at first. The numbers 

 from the foregoing table are as follows :
