he strikes an attitude on a branch, and commences to quack and bark,
with an accompanying movement of his tail. Late in the afternoon, when
the same stillness reigns, the same scenes are repeated. There is a
black variety, quite rare, but mating freely with the gray, from which
he seems to be distinguished only in color.

The track of the red squirrel may be known by its smaller size. He is
more common and less dignified than the gray, and oftener guilty of
petty larceny about the barns and grain-fields. He is most abundant in
old barkpeelings, and low, dilapidated hemlocks, from which he makes
excursions to the fields and orchards, spinning along the tops of the
fences, which afford not only convenient lines of communication, but a
safe retreat if danger threatens. He loves to linger about the orchard;
and, sitting upright on the topmost stone in the wall, or on the
tallest stake in the fence, chipping up an apple for the seeds, his
tail conforming to the curve of his back, his paws shifting and turning
the apple, he is a pretty sight, and his bright, pert appearance atones
for all the mischief he does. At home, in the woods, he is the most
frolicsome and loquacious. The appearance of anything unusual, if,
after contemplating it a moment, he concludes it not dangerous, excites
his unbounded mirth and ridicule, and he snickers and chatters, hardly
able to contain himself; now darting up the trunk of a tree and
squealing in derision, then hopping into position on a limb and dancing
to the music of his own cackle, and all for your special benefit.

There is something very human in this apparent mirth and mockery of the
squirrels. It seems to be a sort of ironical laughter, and implies
self-conscious pride and exultation in the laugher. "What a ridiculous
thing you are, to be sure!" he seems to say; "how clumsy and awkward,
and what a poor show for a tail! Look at me, look at me!"--and he
