COUNT OF COWS. 



The cows were couuted at tlie height of the seasoa on those ;iud several other 

 rookeries. 



COUNT OF HAREMS AND DEAD PUPS. 



The number of bulls in charge of harems, the trampled pups, and the starved 

 pups have been couuted on all the rookeries. 



Combiniug all these and other data we have the basis for an approximate census 

 of the number of breeding seals for the present season on the two islands. The 

 census in detail is given below. To the total number of breeding cows, if correct, 

 the uumbor of pups born would exactly correspond. 



Tlio first two columns in the table represent the estimate based upon the count of 

 cows and harems made in what is known as the height of the season. The count of 

 live pups afterwards made on certain rookeries and parts of rookeries showed them 

 to exceed the original number of cows counted upon these same rookeries by 75 per 

 cent. The totals, therefore, for the various rookeries in the last column have been 

 corrected to correspoud with the actual facts. 



The figures here given represent under rather than over estimates, as the numbers 

 missed in actual count are greater than the possible duplications. The same remark 

 applies to the counts of the trampled and the starved pups.

TOTAL NUMBER OF FUR SEALS. 



To obtain the total number of seals on the islands during the present summer we 

 should add to the 143,071 breeding cows an equal number of pups born, 5,009 active 

 and 2,996 reserve bulls, making a total of 294,141. These animals are, of course, not 

 all alive at the end of the .season. The numbers have been reduced by the loss of 

 trampled and starved pups and by the loss of mothers killed at sea. 



Thus far the census has some claim to accuracy; but there are no trustworthy data 

 obtainable for the number of yearlings, male or female; none for the virgin 2-year- 

 olds, and none for the spared or rejected bachelors, 2-year-olds, 3-year-olds, and 

 half bulls. We have no data for estimating the losses sutfered by the pups iu 

 their first winter at sea. We know little of the enemies they encounter. The
