Specimens of Microtus townsendi from Prospect differ from coast examples 
kindly loaned me by the Bureau of Biological Survey, and assumed to be typical, 
in having the feet and tail darker, and in being of a grayish rather than brownish 
shade, while the coloration is darker mid-dorsally. The foramen magnum is 
smaller with less pronounced superior notch, the interparietal is smaller trans- 
versely, the molariform teeth project more beyond the alveoli at all ages, the 
median spread of the nasals is less abrupt, and the antero-superior portion of the 
zygomatic root of the maxilla is less angular. The material at my disposal indi- 
cates that the Prospect animals may be smaller than typical. These differences 
are mentioned as being of interest when considered in relation to the distribution 
of the species, but are not deemed sufficiently pronounced to merit subspecific 
recognition.

DEPRESSIONS FOUND ON MOOSE TRAILS AND THEIR SIGNIFICANCE 
During the summers of ten years the writer has travelled extensively in the 
remote parts of northern Ontario and Quebec where moose are plentiful. In 
1919, he had the opportunity of observing moose in a district where the lowlands 
between the rock hills were of sand, silt, and clay instead of the moss bogs or

muskeg which are so common. Through the forests in this section, the moose 
trails were more distinct than in the muskeg, and in the moist silt and clay the 
tracks were sharply defined. During the months of May, June, July, August, 
and the early part of September nothing unusual was noted along these trails. 
On the night of September 21, 1919, while sleeping in a prospector’s cabin, the 
writer was awakened by a moose-call. The sound seemed to come from a point
