 by men who have been explorers and hunters in 

 the service of the Hudson's Bay Company, no 

 matter how far north Indians or white men may

 "sometimes that of the blue crane. The crane builds 

 its nest on the top of a muskrat house, just as 

 the geese do in that section. It lays two eggs, 

 much larger than those of a goose, especially in 

 length, and one of the cranes commonly keeps 

 watch by the nest. The nests of the ducks are

 I found the den of a she-wolf in the swamp, and 

 we took her litter of six whelps. Afterwards we 

 trapped tlv 1 old one. We got thirty-five dollars
