His busiest time is in the Indian summer.

Then he gathers burs and hazel-nuts like a plodding farmer, working continuously every day for hours; saying not a word; cutting off the ripe cones at the top of his speed, as if employed by the job, and examining every branch in regular order, as if careful that not one should escape him; then, descending, he stores them away beneath logs and stumps, in anticipation of the pinching hunger days of winter.
He seems himself a kind of coniferous fruit,--both fruit and flower.

The resiny essences of the pines pervade every pore of his body, and eating his flesh is like chewing gum.
One never tires of this bright chip of nature,--this brave little voice crying in the wilderness,--of observing his many works and ways, and listening to his curious language.

His musical, piny gossip is as savory to the ear as balsam to the palate; and, though he has not exactly the gift of song, some of his notes are as sweet as those of a linnet--almost flute-like in softness, while others prick and tingle like thistles.

He is the mocking-bird of squirrels, pouring forth mixed chatter and song like a perennial fountain; barking like a dog, screaming like a hawk, chirping like a blackbird or a sparrow; while in bluff, audacious noisiness he is a very jay.
[Illustration: TRACK OF DOUGLAS SQUIRREL ONCE DOWN AND UP A PINE-TREE WHEN SHOWING OFF TO A SPECTATOR.] In descending the trunk of a tree with the intention of alighting on the ground, he preserves a cautious silence, mindful, perhaps, of foxes and wildcats; but while rocking safely at home in the pine-tops there is no end to his capers and noise; and woe to the gray squirrel or chipmunk that ventures to set foot on his favorite tree! No matter how slyly they trace the furrows of the bark, they are speedily discovered, and kicked down-stairs with comic vehemence, while a torrent of angry notes comes rushing from his whiskered lips that sounds remarkably like swearing.
