and nt the expiration of fifteen years of sparing the seals 24.000 maybe 

 taken the first year. 28,000 the second, 32,000 the third, 36,000 the 

 fourth, 41,000 the fifth; more than 100,000 in the five years. Hence, 

 with economical management, that is, sparing one-fifth of the seals, 

 32,000 may be taken every year permanently, or, at least, for a very 

 long time. 



4. In addition, during the fifteen years of the sparing 60,000 or 70,000 

 bachelors may be taken, making a total of 230,000. 



5. If there should be no sparing, the whole seal species would be ex- 

 tinct forever at the expiration of fifteen years, and during all that time 

 it would not be possible, using everv exertion, to procure more than 

 50,000 seals. 



It must be said here that the most moderate estimates have been 

 made in the table as to r,he increase of the seals and the decrease of the 

 cows has been taken at the average rate. Moreover, on the island of 

 St. Paul, in 1830 and 1837, instead of 7,900 seals, only 4,800 were killed 

 in 1830 and 1837, and consequently 1,500 cows were spared therein 

 two years, which were not taken into account in drawing up the table, 

 and which may yield a very large increase. 



In confirmation of the estimates with regard to the increase of the 

 seals on the island of St. Paul I annex a table of the increase of the 

 seals which were spared on the island of St. George in 1820 and 1827, 

 based upon the same reasoning as the preceding, which shows plainly 

 that my estimates were very near the truth. (See Table No. 3).
