One of the enemies of the chipmunk, as I discovered lately, is the weasel. I was sitting in the woods one autumn day when I heard a small cry, and a rustling amid the branches of a tree a few rods beyond me. Looking thither I saw a chipmunk fall through the air, and catch on a limb twenty or more feet from the ground. He appeared to have dropped from near the top of the tree.

He secured his hold upon the small branch that had luckily intercepted his fall, and sat perfectly still. In a moment more I saw a weasel—one of the smaller red varieties—come down the trunk of the tree, and begin exploring the branches on a level with the chipmunk.

I saw in a moment what had happened. The weasel had driven the squirrel from his retreat in the rocks and stones beneath, and had pressed him so closely that he had taken refuge in the top of a tree. But weasels can climb trees, too, and this one had tracked the frightened chipmunk to the topmost branch, where he had tried to seize him. Then the squirrel had, in horror, let go his hold, screamed, and fallen through the air, till he struck the branch as just described. Now his bloodthirsty enemy was looking for him again, apparently relying entirely upon his sense of smell to guide him to the game.

How did the weasel know the squirrel had not fallen clear to the ground? He certainly did know, for when he reached the same tier of branches he began exploring them. The chipmunk sat transfixed with fear, frozen with terror, not twelve feet away, and yet the weasel saw him not.

Round and round, up and down, he went on the branches, exploring them over and over. How he hurried, lest the trail get cold! How subtle and cruel and fiendish he looked! His snakelike movements, his tenacity, his speed!

He seemed baffled; he knew his game was near, but he could not strike the spot. The branch, upon the extreme end of which the squirrel sat, ran out and up from the tree seven or eight feet, and then, turning a sharp elbow, swept down and out at right angles with its first course.

The weasel would pause each time at this elbow and turn back. It seemed as if he knew that particular branch held his prey, and yet its crookedness each time threw him out. He would not give it up, but went over his course again and again.

One can fancy the feelings of the chipmunk, sitting there in plain view a few feet away, watching his deadly enemy hunting for the clue. How his little heart must have fairly stood still each time the fatal branch was struck! Probably as a last resort he would again have let go his hold and fallen to the ground, where he might have eluded his enemy a while longer.

In the course of five or six minutes the weasel gave over the search, and ran hurriedly down the tree to the ground. The chipmunk remained motionless for a long time; then he stirred a little as if hope were reviving. Then he looked nervously about him; then he had recovered himself so far as to change his position. Presently he began to move cautiously along the branch to the bole of the tree; then, after a few moments' delay, he plucked up courage to descend to the ground, where I hope no weasel has disturbed him since.

One season a chipmunk had his den in the side of the terrace above my garden, and spent the mornings laying in a store of corn which he stole from a field ten or twelve rods away. In traversing about half this distance, the little poacher was exposed; the first cover on the way from his den was a large maple, where he always brought up and took a survey of the scene. I would see him spinning along toward the maple, then from it by an easy stage to the fence adjoining the corn; then back again with his booty. One morning I paused to watch him more at my leisure. He came up out of his retreat and cocked himself up to see what my motions meant. His forepaws were clasped to his breast precisely as if they had been hands, and the tips of the fingers thrust into his vest pockets. Having satisfied himself with reference to me, he sped on toward the tree. He had nearly reached it, when he turned tail and rushed for his hole with the greatest precipitation. As he neared it, I saw some bluish object in the air closing in upon him with the speed of an arrow, and, as he vanished within, a shrike brought up in front of the spot, and with spread wings and tail stood hovering a moment, and, looking in, then turned and went away. Apparently it was a narrow escape for the chipmunk, and, I venture to say, he stole no more corn that morning. The shrike is said to catch mice, but it is not known to attack squirrels. The bird certainly could not have strangled the chipmunk, and I am curious to know what would have been the result had he overtaken him. Probably it was only a kind of brag on his part—a bold dash where no risk was run. He simulated the hawk, the squirrel's real enemy, and no doubt enjoyed the joke.

The sylvan folk seem to know when you are on a peaceful mission, and are less afraid than usual. Did not that marmot to-day guess my errand did not concern him as he saw me approach there from his cover in the bushes? But, when he saw me pause and deliberately seat myself on the stone wall immediately over his hole, his confidence was much shaken. He apparently deliberated awhile, for I heard the leaves rustle as if he were making up his mind, when he suddenly broke cover and came for his hole full tilt. Any other animal would have taken to his heels and fled; but a woodchuck's heels do not amount to much for speed, and he feels his only safety is in his hole. On he came in the most obstinate and determined manner, and I dare say if I had sat down in his hole would have attacked me unhesitatingly. This I did not give him a chance to do, and he whipped into his den beneath me with a defiant snort. Farther on, a saucy chipmunk presumed upon my harmless character to an unwonted degree also. I had paused to bathe my hands and face in a little trout brook, and had set a tin cup, which I had partly filled with strawberries as I crossed the field, on a stone at my feet, when along came the chipmunk as confidently as if he knew precisely where he was going, and, perfectly oblivious of my presence, cocked himself up on the rim of the cup and proceeded to eat my choicest berries. I remained motionless and observed him. He had eaten but two when the thought seemed to occur to him that he might be doing better, and he began to fill his pockets. Two, four, six, eight of my berries quickly disappeared, and the cheeks of the little vagabond swelled. But all the time he kept eating, that not a moment might be lost. Then he hopped off the cup, and went skipping from stone to stone till the brook was passed, when he disappeared in the woods. In two or three minutes he was back again, and went to stuffing himself as before; then he disappeared a second time, and I imagined told a friend of his, for in a moment or two along came a bobtailed chipmunk, as if in search of something, and passed up, and down, and around, but did not quite hit the spot. Shortly, the first returned a third time, and had now grown a little fastidious, for he began to sort over my berries, and to bite into them, as if to taste their quality. He was not long in loading up, however, and in making off again. But I had now got tired of the joke, and my berries were appreciably diminishing, so I moved away. What was most curious about the proceeding was, that the little poacher took different directions each time, and returned from different ways. Was this to elude pursuit, or was he distributing the fruit to his friends and neighbors about, astonishing them with strawberries for lunch?

On another occasion I was much amused by three chipmunks, who seemed to be engaged in some kind of game. It looked very much as if they were playing tag. Round and round they would go, first one taking the lead, then another, all good-natured and gleeful as schoolboys. There is one thing about a chipmunk that is peculiar: he is never more than one jump from home. Make a dive at him anywhere and in he goes. He knows where the hole is, even when it is covered up with leaves. There is no doubt, also, that he has his own sense of humor and fun, as what squirrel has not? I have watched two red squirrels for a half hour coursing through the large trees by the roadside where branches interlocked, and engaged in a game of tag as obviously as two boys. As soon as the pursuer had come up with the pursued, and actually touched him, the palm was his, and away he would go, taxing his wits and his speed to the utmost to elude his fellow.

I have observed that any unusual disturbance in the woods, near where the chipmunk has his den, will cause him to shift his quarters. One October, for many successive days, I saw one carrying into his hole buckwheat which he had stolen from a nearby field. The hole was only a few rods from where we were getting out stone, and as our work progressed, and the racket and uproar increased, the chipmunk became alarmed. He ceased carrying in, and after much hesitating and darting about, and some prolonged absences, he began to carry out; he had determined to move; if the mountain fell, he, at least, would be away in time. So, by mouthfuls or cheekfuls, the grain was transferred to a new place. He did not make a "bee" to get it done, but carried it all himself, occupying several days and making a trip about every ten minutes.
