THE GROUND SQUIRREL. 121 The Ground Squirrel is commonly seen running along fences and walls; but it sometimes ascends trees. It is a very | pretty and lively animal. On the back are fine, long black bands, separated on each side by two white ones. It has cheek pouches, which are not found in other squirrels. The Ground Squirrel makes a burrow, commonly about the roots of trees, or by the side of fences. This is a well-constructed house, having several chambers and two openings, so that the Squirrel has every chance to escape if disturbed.
