ALASKA FXIR SEAL. 189 



chapter upon the management of the Sealing business 

 of gradually increasing the killing of the surplus males, 

 with careful watch for effect upon the rookeries, year 

 after year, and, on the other hand, of watching the 

 market so as not to overstock it, will, I trust, be taken 

 in hand very , soon ; but let this fact be noted : these

 state, undergoes many processes before it appears before 

 the public in the form of the well-known Seal- skin ; in 

 fact, if any uninitiated person were to see the skin in 

 the salted state, he would not be able to recognize it in
