 very dark skins are of greatest value. Many are sent 

 to Germany, but some reach the London market 

 directly. The Okhotsk skins, from 50,000 to 100,000 

 (in 1891, 43,235 skins) arrive in London through 

 Japan, or are imported by the Alaska Commercial 

 Company via San Francisco. Each district producing 

 a somewhat different variety, the price varies accord- 

 ingly. It requires a good judge to distinguish the various 

 sorts. 



The chief sorts are as follows : 



Kazan Odnoutsky 



Yiatka Nertchinsky 



Kargopol Kolinsk 



Obskoi Irkutsky 



Tobolsky Podgomay
