590 Life-histories of Northern Animals 



temperate Eastern North America, from Virginia to James 

 Bay and from Nova Scotia to Alaska. As shown in Map 

 35, it begins on our prairies to grade into the larger, 

 brighter-coloured form that E. A. Preble calls campestris. 



In the wooded parts of Manitoba we may expect the typical 

 form of hudsonius, as it has been taken in northern Minnesota, 

 and Preble collected it at Norway House as well as in many 

 places between Lake Winnipeg and Hudson's Bay/ 



ENVIRON- The typical Jumping-mouse (Z. hudsonius) is commonly 

 found in thickets by meadows, and along the edges of the woods; 

 and the prairie form, as far as I have seen, is not an animal 

 of the prairie, but of the prairie border-lands. I never saw it 

 far from the scrubby underbrush that surrounds most of our 

 small lakes, and its favourite localities are the low thickets of 

 brush and weeds, near streams or ponds, among the poplar 

 groves and half-open country. 



MENT 



RANGE 



HOME- I have no evidence on the home-range of the individual, 



but its wonderful powers, no doubt, enable the Jumper to 

 travel much further than any other of the Mice. 



DANCE 



ABUN- I have never heard of a region where Jumping-mice were 



abundant, with the meaning the word would convey if applied 

 to the Meadow-mice. A dozen each summer represent those 

 that have come within my observation. It is, however, very 

 local in distribution, and E. A. Preble got a score of specimens 

 in four days at Oxford House.^ 



BLE 



uNsociA- It seems to be a solitary species. I have never seen two 



adults together, nor have I heard of it except in the case of a 

 pair caught in the same nest. I did, however, find two 

 old ones drowned together in a little water-hole on my farm 

 near Fort Pelly on the 17th of June, 1884. This is the only 

 case of united action that I have observed in the species.
