Chiefly in cornfields and fruitfields ; digs holes in the 

 soil. In autumn it often occurs in the field in large 

 colonies. Food : grain, beans, peas, potatoes, turnips, 

 carrots. In winter in the barns and dwelling-houses 

 of farmers. 



Regarding the means of destroying those mice which 

 are sometimes damaging to agriculture (M. sylvaticus 

 andilf. Tninutus), see methods mentioned under "Field- 

 vole " (p. 43). 



Family : Arvieolidse ( Vole Family). 



The large voles are also popularly called " rats," the 

 smaller ones " mice." They closely resemble the true 

 mice and rats (p. 38), but are distinguished from 

 them by their plumper, more compressed body; a 

 a thicker head with blunt snout, and ears quite hidden 

 in the fur ; and a short, tolerably hairy tail, on which 

 no rings of scales can be distinguished. There are on 

 each side of each jaw three back teeth, of which each 

 appears to consist of two rows of three-sided prisms.
