74 REPORT OF NEW JERSEY STATE MUSEUM. 
W. Warrington obtained two specimens in a muskrat house not 
far from Salem, November 21, 1808, sixty-two years after the 
original one was taken. Subsequently Mr. Rhoads secured speci- 
mens from muskrat houses on Cohansey Creek and at Greenwich, 
and no doubt the mouse is found in similar localities all along 
the tide water streams and marshes of southern New Jersey.

This is our most abundant native long-tailed mouse, found 
about fence rows, in woods and thickets and under the over- 
hanging banks of streams. It is a beautiful and harmless little 
animal living upon all sorts of seeds, roots, nuts and such grain 
as it finds scattered about. It forms granaries or store houses 
in hollows, in trees and similar receptacles and builds its nest in 
all sorts of places sometimes making use of an old bird’s nest ten 
feet above the ground, this is covered over and thus protected 
serves the mouse’s purpose admirably. 
These mice are mainly nocturnal and their tracks in the 
freshly fallen snow testify to their activity and abundance. In 
camps and similar buildings out in the woods the white-footed
