 The Marmots live on the elevated sides of the highest mountains, near the limit of 

 perpetual snow They are found in families of from six to fifteen : and towards the 

 month of September dig a hole on a southern exposure, which at five or six feet 

 from its entrance divides into two branches, leading to chambers of from three to 

 seven feet in diameter, stored with hay and moss, where they hybernate. When 

 they leave their retreat to seek food, a centinel is placed upon a height to give the 

 alarm, which he does by a kind of whistle, when they retire to their holes. They 

 store up no provisions, their long torpor rendering this unnecessary ; but at the end 

 of autumn they are very fat, and are then taken in great numbers to be used as food.
