The squirrel would shoot up the tree, making only a brown streak from the bottom to the top; would seize his nut and rush down again in the most hurried manner. Half way to his den, which was not over three rods distant, he would rush up the trunk of another tree for a few yards to make an observation. No danger being near, he would dive into his den and reappear again in a twinkling.

Returning for another nut, he would mount the second tree again for another observation. Satisfied that the coast was clear, he would spin along the top of the ground to the tree that bore the nuts, shoot up it as before, seize the fruit, and then back again to his retreat.

Never did he fail during the half hour or more that I watched him to take an observation on his way both to and from his nest. It was "snatch and run" with him. Something seemed to say to him all the time: "Look out! look out!" "The cat!" "The hawk!" "The owl!" "The boy with the gun!"

It was a bleak December morning; the first fine flakes of a cold, driving snowstorm were just beginning to sift down, and the squirrel was eager to finish harvesting his nuts in time. It was quite touching to see how hurried and anxious and nervous he was. I felt like going out and lending a hand. The nuts were small, poor pig-nuts, and I thought of all the gnawing he would have to do to get at the scanty meat they held. My little boy once took pity on a squirrel that lived in the wall near the gate, and cracked the nuts for him, and put them upon a small board shelf in the tree where he could sit and eat them at his ease.

The red squirrel is not so provident as the chipmunk. He lays up stores irregularly, by fits and starts; he never has enough put up to carry him over the winter; hence he is more or less active all the season. Long before the December snow, the chipmunk has for days been making hourly trips to his den with full pockets of nuts or corn or buckwheat, till his bin holds enough to carry him through to April. He need not, and I believe does not, set foot out of doors during the whole winter. But the red squirrel trusts more to luck.

As alert and watchful as the red squirrel is, he is frequently caught by the cat. My Nig, as black as ebony, knows well the taste of his flesh. I have known him to be caught by the black snake and successfully swallowed. The snake, no doubt, lay in ambush for him.

This fear, this ever-present source of danger of the wild creatures, we know little about. Probably the only person in the civilized countries who is no better off than the animals in this respect is the Czar of Russia. He would not even dare gather nuts as openly as my squirrel. A blacker and more terrible cat than Nig would be lying in wait for him and would make a meal of him. The early settlers in this country must have experienced something of this dread of apprehension from the Indians. Many African tribes now live in the same state of constant fear of the slave-catchers or of other hostile tribes. Our ancestors, back in prehistoric times, must have known fear as a constant feeling. Hence the prominence of fear in infants and children when compared with the youth or the grown person. Babies are nearly always afraid of strangers. In the domestic animals also, fear is much more active in the young than in the old. Nearly every farm boy has seen a calf but a day or two old, which its mother has secreted in the woods or in a remote field, charge upon him furiously with a wild bleat, when first discovered. After this first ebullition of fear, it usually settles down into the tame humdrum of its bovine elders.

Eternal vigilance is the price of life with most of the wild creatures. There is only one among them whose wildness I cannot understand, and that is the common water turtle. Why is this creature so fearful? What are its enemies? I know of nothing that preys upon it. Yet see how watchful and suspicious these turtles are as they sun themselves upon a log or a rock. While you are yet many yards away from them, they slide down into the water and are gone.

The land turtle, on the other hand, shows scarcely a trace of fear. He will indeed pause in his walk when you are very near him, but he will not retreat into his shell till you have poked him with your foot or your cane. He appears to have no enemies; but the little spotted water turtle is as shy as if he were the delicate tidbit that every creature was searching for. I did once find one which a fox had dug out of the mud in winter, and carried a few rods and dropped on the snow, as if he had found he had no use for it.

One can understand the fearlessness of the skunk. Nearly every creature but the farm-dog yields to him the right of way. All dread his terrible weapon. If you meet one in your walk in the twilight fields, the chances are that you will turn out for him, not he for you. He may even pursue you, just for the fun of seeing you run. He comes waltzing toward you, apparently in the most hilarious spirits.

The coon is probably the most courageous creature among our familiar wild animals. Who ever saw a coon show the white feather? He will face any odds with perfect composure. I have seen a coon upon the ground, beset by four men and two dogs, and never for a moment losing his presence of mind, or showing a sign of fear. The raccoon is clear grit.

The fox is a very wild and suspicious creature, but curiously enough, when you suddenly come face to face with him, when he is held by a trap, or driven by the hound, his expression is not that of fear, but of shame and guilt. He seems to diminish in size and to be overwhelmed with humiliation. Does he know himself to be an old thief, and is that the reason of his embarrassment? The fox has no enemies but man, and when he is fairly outwitted he looks the shame he evidently feels.

In the heart of the rabbit fear constantly abides. How her eyes protrude! She can see back and forward and on all sides as well as a bird. The fox is after her, the owls are after her, the gunners are after her, and she has no defense but her speed. She always keeps well to cover. The northern hare keeps in the thickest brush. If the hare or rabbit crosses a broad open exposure it does so hurriedly, like a mouse when it crosses the road. The mouse is in danger of being pounced upon by a hawk, and the hare or rabbit by the snowy owl, or else the great horned owl.

A friend of mine was following one morning a fresh rabbit track through an open field. Suddenly the track came to an end, as if the creature had taken wings,—as it had after an unpleasant fashion. There, on either side of its last foot imprint, were several parallel lines in the snow, made by the wings of the great owl that had swooped down and carried it off. What a little tragedy was seen written there upon the white, even surface of the field!

The rabbit has not much wit. Once, when a boy, I saw one that had been recently caught, liberated in an open field in the presence of a dog that was being held a few yards away. The poor thing lost all presence of mind, and was quickly caught by the clumsy dog.

A hunter once saw a hare running upon the ice along the shore of one of the Rangeley lakes. Presently a lynx appeared in hot pursuit; as soon as the hare found it was being pursued, it began to circle, foolish thing. This gave the lynx greatly the advantage as it could follow in a much smaller circle. Soon the hare was run down and seized.

I saw a similar experiment tried with a red squirrel with quite the opposite results. The boy who had caught the squirrel in his wire trap had a very bright and nimble dog about the size of a fox, that seemed to be very sure he could catch a red squirrel under any circumstances if only the trees were out of the way. So the boy went to the middle of an open field with his caged squirrel, the dog, who seemed to know what was up, dancing and jumping about him. It was in midwinter; the snow had a firm crust that held boy and dog alike. The dog was drawn back a few yards and the squirrel liberated.

Then began one of the most exciting races I have witnessed for a long time. It was impossible for the lookers-on not to be convulsed with laughter, though neither dog nor squirrel seemed to regard the matter as much of a joke. The squirrel had all his wits about him, and kept them ready for instant use. He did not show the slightest confusion. He was no match for the dog in fair running, and he discovered this fact in less than three seconds; he must win, if at all, by strategy. Not a straight course for the nearest tree, but a zigzag course, yea, a double or treble zigzag course. Every instant the dog was sure the squirrel was his, and every instant he was disappointed. It was incredible and bewildering to him. The squirrel dodged this way and that. The dog looked astonished and vexed. Then the squirrel issued from between his enemy's hind legs and made three jumps towards the woods before he was discovered. Our sides ached with laughter, cruel as it may seem.

It was evident the squirrel would win. The dog seemed to redouble his efforts. He would overshoot the game, or shoot by it to the right or left. The squirrel was the smaller craft, and could out-tack him easily. One more leap and the squirrel was up a tree, and the dog was overwhelmed with confusion and disgust. He could not believe his senses. "Not catch a squirrel in such a field as that? Go to, I will have him yet!" and he bounded up the tree as high as one's head, and then bit the bark of it in his anger and chagrin.

The boy says his dog has never bragged since about catching red squirrels "if only the trees were out of reach!"

When any of the winged creatures are engaged in a life and death race in that way, or in any other race, the tactics of the squirrel do not work; the pursuer never overshoots nor shoots by his mark. The flight of the two is timed as if they were parts of one whole. A hawk will pursue a sparrow or a robin through a zigzag course and not lose a stroke or half a stroke of the wing by reason of any darting to the right or left. The clue is held with fatal precision. No matter how quickly nor how often the sparrow or the finch changes its course, its enemy changes, simultaneously, as if every move was known to it from the first.

The same thing may be noticed among the birds in their love chasings; the pursuer seems to know perfectly the mind of the pursued. This concert of action among birds is very curious. When they are on the alert, a flock of sparrows, or pigeons, or cedar-birds, or snow buntings, or blackbirds, will all take flight as if there were but one bird, instead of a hundred. The same impulse seizes every individual bird at the same instant, as if they were sprung by electricity.

Or when a flock of birds is in flight, it is still one body, one will; it will rise, or circle, or swoop with a unity that is truly astonishing.

A flock of snow buntings will perform their aerial evolutions with a precision that the best-trained soldiery cannot equal. Have the birds an extra sense which we have not? A brood of young partridges in the woods will start up like an explosion, every brown particle and fragment hurled into the air at the same instant. Without word or signal, how is it done?
