by the same abnormal disregard of impediments as the lemmings. 
Though usually averse to taking to water, they would not at such 
times stop at rivers even though as large as the Ohio or Niagara, 
and vast numbers were drowned in their efforts to swim across. 
Although no such migrations of the species have been noticed of late 
years—owing probably to its diminished numbers—nevertheless 
the abundance of these squirrels in a given locality at different sea- 
sons has been observed to be extremely variable, and it is more than 
likely that such mass movements do take place though they are not 
so easily observed as formerly. 
The economic status of the gray squirrel is in general the same 
in all respects as that of the fox-squirrel. Owing to its scarcity 
in this vicinity it is even more worthy of consideration when in a 
wild state. In cities and towns, however, when exceedingly numer- 
ous, its destruction of birds’ nests may call for repressive measures. 
In such cases a due balance of nature may easily be regained, for the 
squirrels are easily killed, and there are many who are too glad to do 
at. 
RED SQUIRREL; CHICKAREE. 
Sciurus hudsonicus loquax Bangs. 
(Proc. Biol. Soc. Wash., X., 1896, p. 161.) 
The red squirrel, or chickaree, is not found within the limits of 
Champaign county. It is said to occur at Onarga, in Iroquois 
county. It was probably introduced there, but is native in the 
northern part of the state. Kennicott says that it is found spar- 
ingly in heavy timber in Illinois but not in the southern part. We 
have no data by which to determine the southern limit of its range. 
CHIPMUNK. 
Tamtas striatus lystert (Richardson). 
Sciurus (Tamias) lysteri Rich., Faun. Bor. Amer., Mamm., I., 1829, p. 181, Pl. 15. 
The striped chipmunk (Tamzas striatus) is found north to New 
Brunswick and Ontario, west to southern Michigan and Wiscon- 
sin, and south to Georgia, Alabama, and Florida, but it is not 
found on the Atlantic coast plains. It occurs as far west as Kansas, 
Missouri, and Minnesota. Over this area it is divided into several 
subspecies.
