 high up and far back on the head, provided with a muscular ap- 

 paratus for bringing down the upper portion over the orifice, bor-

Observations. This interesting animal is one of the most com- 

 mon in New England. It is vigilant, and though not very active, 

 still it is almost impossible to surprise and take it at a distance 

 from the burrow. It is perfectly cleanly in all its habits, is sus- 

 ceptible of domestication, and becomes a very agreeable pet. 

 It is well known to hybernaie. It goes into winter quarters some 

 time in October, unless the weather is quite mild, and the means 

 of subsistence plentiful ; it is then very fat. Its sense of hearing 

 is extremely acute, and hence it is so rarely surprised away from 

 home, as the least noise, when it is collecting the materials for its 

 nest, or feeding, is timely perceived, so that it escapes while the 

 suspicious object is at a distance.
