constantly changing and of such interest in all their phases as are 
those of the Flying Squirrel, a complete account can scarcely be 
given. Certainly it is not easy for words to represent the merry, 
rollicking, don't-care manner in which they do everything. Such a 
combination of earnestness and carelessness is seldom seen. For 
they are earnest about their work, and in emptying a box of nuts 
they seem to feel the great importance of their undertaking and the 
necessity of soberness and dignity in its execution, but yet one can-

The late Dr. Gideon B. Smith, of Baltimore, in a letter to Audubon 
and Bachman, speaks thus ol these squirrels : “ They are gregarious,

company of other and even quite different animals. For example, I 
once assisted in taking down an old martin -box, which had been for 
a great number of years on the top of a - venerable locust tree near 
my house, and which had some eight or ten apartments. As the box 
fell to the ground we were surprised to see the great numbers of 
Flying Squirrels, screech-owls, and leather-winged bats running from 
it. We caught several of each, and one of the Flying Squirrels was 
kept as a pet in a cage for six months. The various apartments of 
the box were stored with hickorynuts, chestnuts, acorns, corn, &c., 
intended for the winter supply of food. There must have been as 
many as twenty Flying Squirrels in the box, as many bats, and we
