CARNIVORA. MUSTELIDiE. 45 



Observations. There is some doubt in relation to the identity 

 of the European and American Weasel. The tail of the Amer- 

 ican is evidently shorter than that of the European. In other 

 respects there is a great similarity. It is not so common as the 

 following species, at least in the western part of the State. There 

 is no occasion for mistaking this species for its congener, com- 

 monly called the White Weasel, as the latter is always larger, 

 and has a longer tail, which is always terminated with a black 

 pencil of hairs, whereas, in the former, it is always short, and of 

 a uniform color. It feeds upon mice, moles, eggs, chickens, &c. 

 The smallness of the animal fits it better for pursuing mice than 

 larger animals, and hence it may be of great service in barns, and 

 hav and grain ricks, in the destruction of vermin ; and hence, too, 

 it should be protected, even if it should occasionally take an egg 

 or a chicken for a change of diet.
