It was not very long before the chipmunk was going to and from her den as usual, though the dread of the black monster seemed ever before her, and gave speed and extra alertness to all her movements. In early summer four young chipmunks emerged from the den, and ran freely about. There was nothing to disturb them, for, alas! Nig herself was now dead.
One summer day I watched a cat for nearly a half hour trying her arts upon a chipmunk that sat upon a pile of stone. Evidently her game was to stalk him. She had cleared half the distance, or about twelve feet, that separated the chipmunk from a dense Norway spruce, when I chanced to become a spectator of the little drama. There sat the cat crouched low on the grass, her [p21] big, yellow eyes fixed upon the chipmunk, and there sat the chipmunk at the mouth of his den, motionless, with his eyes fixed upon the cat. For a long time neither moved. “Will the cat bind him with her fatal spell?” I thought. Sometimes her head slowly lowered and her eyes seemed to dilate, and I fancied she was about to spring. But she did not. The distance was too great to be successfully cleared in one bound. Then the squirrel moved nervously, but kept his eye upon the enemy. Then the cat evidently grew tired and relaxed a little and looked behind her. Then she crouched again and riveted her gaze upon the squirrel. But the latter would not be hypnotized; he shifted his position a few times and finally quickly entered his den, when the cat soon slunk away.
In digging his hole it is evident that the chipmunk carries away the loose soil. Never a grain of it is seen in front of his door. Those pockets of his probably stand him in good stead on such occasions. Only in one instance have I seen a pile of earth before the entrance to a chipmunk’s den, and that was where the builder had begun his house late in November, and was probably too much hurried to remove this ugly mark from before his door. I used to pass his place every morning in my walk, and my eye always [p22] fell upon that little pile of red, freshly-dug soil. A little later I used frequently to surprise the squirrel furnishing his house, carrying in dry leaves of the maple and plane tree. He would seize a large leaf and with both hands stuff it into his cheek pockets, and then carry it into his den. I saw him on several different days occupied in this way. I trust he had secured his winter stores, though I am a little doubtful. He was hurriedly making himself a new home, and the cold of December was upon us while he was yet at work. It may be that he had moved the stores from his old quarters, wherever they were, and again it may be that he had been dispossessed of both his house and provender by some other chipmunk.
I have been told by a man who says he has seen what he avers, that the reason why we do not find a pile of fresh earth beside the hole of the chipmunk is this: In making his den the workman continues his course through the soil a foot or more under the surface for several yards, carrying out the earth in his cheek pouches and dumping it near the entrance. Then he comes to the surface and makes a new hole from beneath, which is, of course, many feet from the first hole. This latter is now closed up, and henceforth the new one alone is used. I have no doubt this is the true explanation.

When nuts or grain are not to be had, these thrifty little creatures will find some substitute to help them over the winter. Two chipmunks near my study were occupied many days in carrying in cherry pits which they gathered beneath a large cherry-tree that stood ten or twelve rods away. As Nig was no longer about to molest them, they grew very fearless, and used to spin up and down the garden path to and from their source of supplies in a way quite unusual with these timid creatures. After they had got enough cherry pits, they gathered the seed of a sugar maple that stood near. Many of the keys remained upon the tree after the leaves had fallen, and these the squirrels harvested. They would run swiftly out upon the ends of the small branches, reach out for the maple keys, snip off the wings, and deftly slip the nut or samara into their cheek pockets. Day after day in late autumn, I used to see them thus occupied.
As I have said, I have no evidence that more than one chipmunk occupy the same den. One March morning after a light fall of snow I saw where one had come up out of his hole, which was in the side of our path to the vineyard, and after a moment’s survey of the surroundings had started off on his travels. I followed the track to see where he had gone. He had passed [p24] through my woodpile, then under the beehives, then around the study and under some spruces and along the slope to the hole of a friend of his, about sixty yards from his own. Apparently he had gone in here, and then his friend had come forth with him, for there were two tracks leading from this doorway. I followed them to a third humble entrance, not far off, where the tracks were so numerous that I lost the trail. It was pleasing to see the evidence of their morning sociability written there upon the new snow.
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 [p25] 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.
