Pine Mouse 
This is the most distinct of all the meadow mouse tribe. So 
soft and silky is its fur that we think at once of the mole, the 
very small eyes and ears likewise resemble this animal, but the 
teeth at once show it to be a mouse and the rusty colour is not found 
in any of the mole tribe. The points that the pine mouse pos- 
sesses in common with the mole are evidently the results of similar 
habits, for this little beast is the most strictly subterranean of any 
of the mice. He is not content with a runway on the surface 
among the grass roots but must go strictly underground, and many 
a one have | caught in raised tunnels that I took to be the work 
of the moles. Much damage done to vegetables and plants in the 
garden which is usually attributed to the meadow mouse is, I am 
quite sure, really the work of this silky haired cousin, the pine 
mouse.
