From this table behold that — 



(a) Every fifteen years, from 3,600 females, there can be received in 

 sixteen years 24,700 seals; in sixteen years still more; and in twenty 

 years 41,640. 



{b) In the twenty-first year the incomes begin to diminish, provided 

 that if in the meantime, or the following sixteen years, a certain num- 

 ber of young seals are not left to breed ; and if every year a known 

 number are left to breed, then in all following years the yield will never 

 be less than 20,000 every year. 



Table III. — Calculations as to the taking of the seals on the island of St. George, made 

 up from two years, and based upon that experience. {1827-28.) 



A grand total of 29,270 seals. 



The actual taking of seals was as follows : 



Seals. 



In 1828 4,778 



In 1829 3,661 



lul830 2,834 



In 1831 3,084 



In 1832 3,296 



In 1833 3,212 



Seals. 



In 1834 3,051 



In 1835 2, 528 



In 1836 2,550 



In 1837 2,582 



Total 31,576 



From this table it will be seen that up to 1838 my calculation makes 

 a yield of 29,270 seals; while the actual result was 31,570; making a 

 difference of 2,306. 



The difference determines that the hypothesis upon which the table 

 is based is correct. 



VENIAMINOV'S ACCOUNT OF THE DISCOVERY OF THE PRIBILOF 



ISLANDS.! 



Location and discovery. — Under the name of the Pribilof Islands 

 are known two small islands lying in Bering Sea, between 56° and 57° 

 north latitude, and 168° and 170° west longitude. 



Stoorman G. Pribilof, who had been on the American Coast for some 

 time and observed the indications of islands in Bering Sea, became con- 

 vinced of their existence; and the embarrassed circumstances of his 

 company finally induced him to attempt their discovery. * * * He 

 was considered one of the best navigators of that region. * * *
