and shorter and it lives almost exclusively undergroimd. It trav- 

 els in burrows, made by itself and by moles, and feeds on fine roots, 

 root bulbs, the bark of wood foots, etc. It often eats potatoes, lily 

 bulbs and the bark froim the roots of young fruit trees. The most 

 injurious in its habits of all the native mice. 



Muskrat, Fiber zibethicus Linn. 



Common along water courses and in swampy lands throughout 

 the State. Frequently forages in truck patches and gardens adja- 

 cent to streams of water. Its skins are sold in such numbers that 

 it has become the most valuable fur-beamig animal found in the 

 United States. 



Cooper's Lemming Mouse, Synaptomys cooperi Baird. 



This mouse, by a casual observer, might be mistaken for a com- 

 mon meadow mouse. Its tail, however, is much shorter, being only 

 five-eighths of an inch in length, and the fur is softer and fuller. 

 It is a rare mouse in most localities. Surber has collected it at 

 "White Sulphur Springs. I trapped several specimens in mouse 

 roads through the beds of. sphagnum moss in Cranberry Glades 

 and have taken it also along a little woodland stream at French 

 Creek. It is said to feed on the stems of grasses, clover, etc. It is 

 not seriously injurious in its habits. 



Meadow Jumping IMouse, Zapiis hudsonhcs Zimm. 



I have records of this mouse, or its subspecies, americanus, from 

 French Creek and Sherrard. Unfortunately no skins have been 

 preserved and the records are indefinite. 



Woodland Jumping Mouse, Zapus insignis Mill. 



I have collected this beautiful little creature at French Creek, 

 Cranberry Glades and at the foot of Turkeybone mountain, in 

 Randolph county. It is said by Surber to be fairly common, but 

 locally distributed, in the Canadian zone. I have found it very 

 rare except in the vicinity of Cranberry Glades, where, in the sum- 

 mer of 1909, it seemed fairly abundant.
