near the young. After several advances and retreats she finally 

 came and seized the young in her mouth when I caught her in my 

 hand. When released she returned to the knot-hole with the young 

 squirrel. These dates (April 16 and August 19), are of interest in 

 showing so wide a range in the breeding season of the Flying 

 Squirrel. 



On December 16, 1890, a family of six Flying Squirrels was found 

 by Mr. J. M. Beck near Burlington. They were all full-grown. 

 On Thanksgiving day, several years ago, Prof. U. 0. Cox, then of 

 Farmland, Indiana, found 15 Flying Squirrels in a small rotten 

 stump a little higher than a man's head. 



It is remarkable the number of Flying Squirrels that can be dis- 

 covered in any wood by knocking on the old dead snags or trees, 

 particularly in the spring. We have found them in old oaks, beeches, 

 maples, ash, willows, sycamores and hickories, as well as in various 

 old buildings. They seem to breed chiefly early in the spring, 

 about sugar-making time. A second or third litter may be pro- 

 duced later in the season. 



Flying Squirrels make very interesting pets. Several years ago 

 one of us had two which were kept as pets for several weeks. They 

 had the freedom of one room in the house. During the day they 

 lay curled up in a box provided and made comfortable for that 

 purpose. At night, particularly before midnight, they would come 

 out to play about the room and to accept the nuts and other food 

 offered them. One night a drawer containing a number of bird- 

 skins was inadvertently left open. One of the squirrels got into it, 

 ate one of the skins and as a result died of arsenic poisoning.

 Beaver. 



The Beaver was at one time pretty common in the northern part 

 of Indiana. There still exist vestiges of one or more beaver-dams 

 in the outlet between Lost Lake and the Tippecanoe River.
