SCIURUS HUDSONICUS LOQUAX Bangs. 

 RED SaUIRREL, CHICKAREE. 



The red squirrel appears to avoid the swamps and is found only in 

 restricted portions of the Kankakee Valley. At Roselawn and 

 Mountayr it does not occur. I obtained one specimen near Ayles- 

 worth, and it is said to live in large numbers about the village of Boone 

 Grove. It has also been taken at Laporte. 



TAMIAS STRIATUS (Linnaeus). 

 CHIPMUNK. 



The chipmunk of this region seems to be the southern form, typical 

 striatus. Apparently it does not occur at Bluegrass Landing, but it 

 is abundant about Mountayr and occurs in fewer numbers at Ayles- 

 worth. It has also been taken at Laporte. 



CITELLUS FRANKLINI (Sabine). 

 GRAY GROUND SQUIRREL. 



This animal is locally known as the prairie squirrel. I obtained 

 three specimens at Mountayr, where I found a colony living in a 

 field of oats, to which they did not seem to be doing any damage. I 

 could not learn of any other colonies in that vicinity, although it has 

 been reported from Benton, Jasper, White, and Porter counties. 

 Mr. W. S. Blatchley reports digging one out of a mound near Boone 

 Grove on October 6, at which date it had already begun to hibernate. 



CITELLUS TRIDECEMLINEATUS (MitchiU). 

 THIRTEEN-LINED GROUND SQUIRREL. 



I noticed the burrows of the thirteen-lined ground squirrel in rail- 

 way embankments at a number of places where I did not do any 

 collecting, and it is probable that it has extended its range, locally, at 

 least, by followmg these embankments through the marshes. This 

 is another species which does not occur at Bluegrass Landing. 



MARMOTA MONAX (Linnaeus). 

 WOODCHUCK. 



Woodchucks are very abundant, and seem to inhabit every sand 

 hill and elevated point throughout the region. Porter County pays a 

 bounty of 10 cents for each animal killed and a statement furnished 

 me by the county treasurer shows that an average of about 1,400 

 woodchucks a year have been killed for the five years ending with 

 1905, at a total cost to the county of $700. Apparently the bounty 

 has not caused any appreciable diminution in numbers. 



I obtained a woodchuck which had been ''treed" by dogs in a
