Pennsylvania Meadow Mouse, or Vole 



Meadow mice make long intricate runways in matted grass on 

 uncultivated borders of fields, in wet meadows, or near streams in 

 lowland pastures. In such locations these mice may be found in most 

 parts of the State. On a high knob at Mercers Bottom that had not 

 been inundated by the flood waters of the Ohio River, runways of 

 these mice were found in grass and weeds along a fence at the edge of a 

 cultivated field. Near Huntington the runways of a colony were 

 found in a tangle of matted grass and briers on both sides of a small 

 spring stream. Although the rimways in the wet pasture divided by 

 Muddlety Creek were flooded, the meadow mice were not driven away. 

 At Philippi meadow mice were trapped in runwa3^s on the gentle slope 

 of a hill overgrown with broomsedge. Near Fourteen, a nest contain- 

 ing several young was thrown out by the plow on a hillside field below 

 a hemlock grove. In Cranberry Glades most of these mice were 

 caught in runways in the grass and moss growing between moss mounds 

 in a wet meadow. Fred E. Brooks (1911, p. 18) reports that he had 

 trapped one within a few yards of the summit of Spruce Knob, 

 Pendleton County, or approximately 4,650 feet altitude.

MICROTUS CHROTORRHINUS CAROLINENSIS Komarek 



Smoky Mottntain Rock Vole 



Although at present loiown to occur only at Cranberry Glades, this 

 vole may be found to inhabit similar isolated areas throughout the 

 Allegheny Mountain region of West Virginia. Cranberry Glades is a 

 natural basin about half a mile in length and a quarter of a mile in 

 width. Blueberry, cranberry, and sphagnum are among the conspic- 

 uous plants growing here, E. A. Preble, in November 1909, obtained 

 a number of rock voles about an eighth of a mile south of this basin 

 in a mixed, fairly open forest of beech, maple, and oak on a gentle 

 slope at the base of Kennison Mountain. They were trapped at the 

 entrances to little burrows in the moss that filled the intervals 

 between rocks embedded in the ground. No runways were found.
