These are, however, not the largest dimensions. I have seen one from Dutchess county, 

 and another from Rockland county, measuring sixteen and a half inches ; and my friend Mr. 

 Linsley states, that he has one measuring twenty and a half inches. 



The habits of this animal, as the ruthless destroyer of poultry, are well known ; but these 

 injuries, which are obvious and potent, are, we think, more than counterbalanced by their 

 destruction of hordes of mice which congregate in barns and in stacks of grain exposed in the 

 fields. Upon one occasion, we remember to have seen an example of fifty or sixty mice, 

 whose lacerated remains bore testimony to the valuable services of this species. 



I have never seen the true Ermine in its summer di'ess, and only know it from Pennant's 

 description (Arct. Zool. Vol. 1, p. 75) : " Ears edged with white ; head, back, side and legs, 

 " pale tawny brown ; under side of bod}' white ; lower part of tail brown, end black." 



Our animal is exceedingly active, nocturnal in its habits, and hiding under piles of wood 

 or stone. We do not know whether it makes a burrow. Its geographical limits as yet are 

 not settled. We suj)pose it to be a northern animal, found as far south as Pennsylvania. In 

 its white coat, it is called, in some parts of the State, the Catamingo, and the White 

 Weasel.
