ing its presence known through many long successful raids on 
the food box. A ''catch-’em-alive ’ ’ mouse trap was placed in 
front of a small hole under a decayed log near camp, and three 
were caught in less than ten minutes. Their holes were to be 
found under nearly every stump or fallen log, and at night they 
could be heard scampering about among the leaves. 
Meadow Mole. Microtus pennsylvanicus (Ord). 
Probably more abundant in both counties than present data 
would indicate. In the fields about Kenton several were seen, 
while but a single individual was found in the Lake 33 region. 
This one was accidentally stepped on one evening while going 
through a rather open area to the spring. About Kenton they 
live in thick tangles of brush or under upright remains of cut 
pines, not having been found under fallen or decayed wood. 
Northern Muskrat. Ondatra zihethica zibethica (Linn.). 
Common in both Houghton and Iron Counties, but more abun¬ 
dant in Iron, due no doubt to the fact that they are less trapped 
and annoyed there. Two specimens were caught near camp at 
Lake 33, one a kit and one an adult female, both having as pretty 
fur as the writer has seen on muskrats. In this region the rats 
are more active during the day than is customary for the species 
elsewhere. 
Canada Porcupine. Eretkizon dorsatum (Linn.). 
Abundant in both counties, though more so in Iron than in 
Houghton. While not seen often in the immediate vicinity of 
Kenton (and there is good reason why they should not be), their 
teeth-marks on old buildings bear ample witness to their pres¬ 
ence. About Lake 33 the animals were abundant, and were often 
a nuisance when we were out photographing deer by night. 
Minnesota Varying Hare. Lepus americanus pkaeonotus 
(Allen). 
Found rather commonly in both counties, and is the only form 
of rabbit found, so far as the writer can ascertain. Not often 
seen during the summer, but tracks and faeces are often found 
either in the deep woods or near the edge, and but seldom in the 
open fields.
