Part 7

For an hour or more, that afternoon on the mountain top, my attention was attracted by a peculiar continuous sound that seemed to come from far away to the east. I queried with myself, "Is it the sound of some workman in a distant valley hidden by the mountains, or is its source nearer by me on the mountain side?" I could not determine. It was not a hammering or a grating or the filing of a saw, though it suggested such sounds. It had a vague, distant, ventriloquial character. In the solitude of the mountain top there was something welcome and pleasing in it. Finally I set out to try to solve the mystery. I had not gone fifty yards from camp when I knew I was near the source of the sound. Presently I saw a porcupine on a log, and as I approached the sound ceased, and the animal moved away. A curious kind of chant he made, or note of wonder and surprise at my presence on the mountain,--or was he calling together the clan for a midnight raid upon my camp?

I made my bed that night of ferns and balsam boughs under an overhanging rock, where the storm that swept across the mountain just after dark could not reach me. I lay down, rolled in my blankets, with a long staff by my side, in anticipation of visits from the porcupines. In the middle of the night I was awakened, and, looking out of my den, saw a porcupine outlined against the starlit sky. I made a thrust at him with my staff, when, with a grunt or grumble, he disappeared. A little later I was awakened again by the same animal, or another, which I repelled as before. At intervals during the rest of the night they visited me in this way; my sleep was by short stages from one porcupine to another.

These animals are great gnawers. They seem to be specially fond of gnawing any tool or object that has been touched or used by human hands. They would probably have gnawed my shoes or lunch basket or staff had I lain still. A settler at the foot of the mountain told me they used to prove very annoying to him by getting into his cellar or woodshed at night, and indulging their ruling passion by chewing upon his tool-handles or pails or harness. "Kick one of them outdoors," he said, "and in half an hour he is back again." In winter they usually live in trees, gnawing the bark and feeding upon the inner layer. I have seen large hemlocks quite denuded and killed in this way.

THE OPOSSUM

A new track has appeared upon the snow in my neighborhood here on the Hudson within the past few years. It is a strange track, and suggests some small, deformed human hand. If the dwarfs or brownies we read of in childhood were to walk abroad in winter, they might leave such an imprint behind them as this.

This track, which we seldom see later than December, is made by the opossum. This animal is evidently multiplying in the land, and is extending its range northward. Ten years ago they were rarely found here, and now they are very common. I hear that they are very abundant and troublesome on parts of Long Island. The hind foot of the opossum has a sort of thumb that opposes the other toes, and it is the imprint of this member that looks so strange. The under side of the foot is as naked as the human hand, and this adds to the novel look of the track in the snow.

Late in the fall, my hired man set a trap in a hole in hopes of catching a skunk, but instead he caught a possum by one of its fore feet. The poor thing was badly crippled, and he kept it in a barrel for a couple of weeks and fed it, to try and make amends for the injury he had done. Then he gave it its freedom, though the injured foot had healed but little.

Soon after he set his trap in the same hole, and to his annoyance caught the possum again, this time by one of the hind feet. He brought the quiet, uncomplaining creature to me by its prehensile tail, and asked me what should be done with or for it. I concluded to make a hospital for it in one corner of my study. I made it a nest behind a pile of magazines, and fed and nursed it for several weeks. It never made a sound, or showed the least uneasiness or sign of suffering, that I was aware of, in all that time. By day it slept curled up in its nest. If disturbed, it did not "play possum," that is, did not feign sleep or death, but opened its mouth and grinned up at you in a sort of comical, idiotic way. At night it hobbled about the study, and ate the meat and cake I had placed for it. Sometimes by day it would come out of the corner and eat food under the lounge, eating very much after the manner of a pig, though not so greedily. Indeed, all its motions were very slow, like those of the skunk.

The skin of the opossum is said to be so fetid that a dog will not touch it. A dog is always suspicious of an animal that shows no fear and makes no attempt to get out of his way. This fetidness of the opossum is not apparent to my sense.

After a while my patient began to be troublesome by climbing upon the book-shelves and inspecting the books, so I concluded to discharge him from the hospital. One night I carried him to the open door by his tail, put him down upon the door-sill, and told him to go forth. He hesitated, looked back into the warm room, then out into the winter night, then thought of his maimed feet, and of traps in holes where unsuspecting possums live, and could not reach a decision. "Come," I said, "I have done all I can for you; go forth and shift for yourself." Slowly, like a very old man, he climbed down out of the door and disappeared in the darkness. I have no doubt he regained his freedom with a sigh. It is highly probable that, if a trap is set in his way again, he will put his foot in it as innocently as before.

One day in March one of my neighbors brought to me a handful of young possums, very young, sixteen of them, like newly born mice. The mother had been picked up dead on the railroad, killed, as so often happens to coons, foxes, muskrats, and woodchucks, by the night express. The young were in her pouch, each clinging to its teat, dead. The young are carried and nursed by the mothers in this curious pocket till they are four or five weeks old, or of the size of large mice. After this she frequently carries them about, clinging to various parts of her body, some with their tails wound around hers.

The next winter, two or more possums and a skunk took up their quarters under my study floor. It was not altogether a happy family. Just what their disagreements were about, I do not know, but the skunk evidently tried to roast the possums out. The possums stood it better than I could. I came heartily to wish they were all roasted out. I was beginning to devise ways and means, when I think the skunk took himself off. After that, my only annoyance was from the quarreling of the possums among themselves, and their ceaseless fussing around under there, both day and night. At times they made sounds as if they were scratching matches on the under side of the floor: then they seemed to be remaking or shifting their beds from one side to the other. Sometimes I think they snored in their sleep. One night, as I was going from the house to the study, I heard a rustling in the dry leaves and grass, beside the path. Lighting a match, I approached the spot, and found one of the possums just setting out on his night's excursions. I stooped down and stroked his head and scratched his back, but he did not move; he only opened his mouth a little and looked silly.

WILD MICE

One of the prettiest and most abundant of our native mice is the deer mouse, also called the white-footed mouse; a very beautiful creature, nocturnal in his habits, with large ears, and large, fine eyes full of a wild, harmless look. He is daintily marked, with white feet and a white belly. When disturbed by day he is very easily captured, having none of the cunning or viciousness of the common Old World mouse. He is found in both fields and woods.

It is he who, high in the hollow trunk of some tree, lays by a store of beech-nuts for winter use. Every nut is carefully shelled, and the cavity that serves as storehouse lined with grass and leaves. The wood-chopper frequently squanders this precious store. I have seen half a peck taken from one tree, as clean and white as if put up by the most delicate hands,--as they were. How long it must have taken the little creature to collect this quantity, to hull them one by one, and convey them up to his fifth-story chamber!

But the deer mice do not always carry their supplies home in this manner; they often hide them in the nearest convenient place. I have known them to carry a pint or more of hickory nuts and deposit them in a pair of boots standing in the chamber of an outhouse. Near the chestnut-trees they will fill little pocket-like depressions in the ground with chestnuts; in a grain-field they carry the grain under stones; under some cover beneath cherry-trees they collect great numbers of cherry-pits. Hence, when cold weather comes, instead of staying at home like the chipmunk, they gad about hither and thither looking up their supplies. One may see their tracks on the snow everywhere in the woods and fields and by the roadside. The advantage of this way of living is that it leads to activity, and probably to sociability.

One day, on my walk in the woods, I saw at one point the mice-tracks unusually thick around a small sugar-maple. It was doubtless their granary; they had beech-nuts stored there, I'll warrant. There were two entrances to the cavity of the tree,--one at the base, and one seven or eight feet up. At the upper one, which was only just of the size of a mouse, a squirrel had been trying to break in. He had cut and chiseled the solid wood to the depth of nearly an inch, and his chips strewed the snow all about. He knew what was in there, and the mice knew that he knew; hence their apparent consternation. They had rushed wildly about over the snow, and, I doubt not, had given the piratical red squirrel a piece of their minds. A few yards away the mice had a hole down into the snow, which perhaps led to some snug den under the ground. Hither they may have been slyly removing their stores while the squirrel was at work with his back turned. One more night and he would effect an entrance: what a good joke upon him if he found the cavity empty! These native mice, I imagine, have to take many precautions to prevent their winter stores being plundered by the squirrels, who live, as it were, from hand to mouth.

The wild mice are fond of bees and of honey, and they apparently like nothing better than to be allowed to take up their quarters in winter in some vacant space in a hive of bees. A chamber just over the bees seems to be preferred, as here they get the benefit of the warmth generated by the insects. One very cold winter I wrapped up one of my hives with a shawl. Before long I noticed that the shawl was beginning to have a very torn and tattered appearance. On examination, I found that a native mouse had established itself in the top of the hive, and had levied a ruinous tax upon the shawl to make itself a nest. Never was a fabric more completely reduced into its original elements than were large sections of that shawl. It was a masterly piece of analysis. The work of the wheel and the loom was exactly reversed, and what was once shawl was now the finest and softest of wool.

The white-footed mouse is much more common along the fences and in the woods than one would suspect. One winter day I set a mouse-trap--the kind known as the delusion trap--beneath some ledges in the edge of the woods, to determine what species of mouse was most active at this season. The snow fell so deeply that I did not visit my trap for two or three weeks. When I did so, it was literally packed full of white-footed mice. There were seven in all, and not room for another. Our woods are full of these little creatures, and they appear to have a happy, social time of it, even in the severest winters. Their little tunnels under the snow and their hurried leaps upon its surface may be noted everywhere. They link tree and stump, or rock and tree, by their pretty trails. They evidently travel for adventure and to hear the news, as well as for food. They know that foxes and owls are about, and they keep pretty close to cover. When they cross an exposed place, they do it hurriedly.

The field or meadow mice doubtless welcome the snow. They can now come out of their dens in the ground or beneath the flat stones and lead a more free and active life. The snow is their friend. It keeps off the cold, and it shields their movements from the eyes of their enemies, the owls, hawks, and foxes. Now they can venture abroad from their retreats without fear. They make little tunnels and roadways everywhere over the surface of the ground. They build winter houses under the great drifts. They found little mouse colonies in places where they have never been in summer. The conditions of life with them are entirely changed. They can get at the roots of the grasses, or the various herbs and seeds they feed upon, as well as in the snowless seasons, and without exposure to their enemies.

I fancy they have great times there beneath the drifts. Maybe they have their picnics and holidays then as we have ours in summer. When the drifts disappear in spring, you may often see where they have had their little encampments: a few square yards of the pasture or meadow bottom will look as if a map had been traced upon it; tunnels and highways running and winding in every direction and connecting the nests of dry grass, which might stand for the cities and towns on the map. These runways are smooth and round like pipes, and only a little larger than the bodies of the mice. I think it is only the meadow field-mouse that lives in this way beneath the snow.

I met one of these mice in my travels one day under peculiar conditions. He was on his travels also, and we met in the middle of a mountain lake. I was casting my fly there, when I saw, just sketched or etched upon the glassy surface, a delicate V-shaped figure, the point of which reached about to the middle of the lake, while the two sides, as they diverged, faded out toward the shore. I saw the point of this V was being slowly pushed across the lake. I drew near in my boat, and beheld a little mouse swimming vigorously for the opposite shore. His little legs appeared like swiftly revolving wheels beneath him. As I came near, he dived under the water to escape me, but came up again like a cork and just as quickly. It was laughable to see him repeatedly duck beneath the surface and pop back again in a twinkling. He could not keep under water more than a second or two. Presently I reached him my oar, when he ran up it and into the palm of my hand, where he sat for some time and arranged his fur and warmed himself. He did not show the slightest fear. It was probably the first time he had ever shaken hands with a human being. He had doubtless lived all his life in the woods, and was strangely unsophisticated. How his little round eyes did shine, and how he sniffed me to find out if I was more dangerous than I appeared to his sight!

After a while I put him down in the bottom of the boat and resumed my fishing. But it was not long before he became very restless, and evidently wanted to go about his business. He would climb up to the edge of the boat and peer down into the water. Finally he could brook the delay no longer and plunged boldly overboard; but he had either changed his mind or lost his reckoning, for he started back in the direction from which he had come, and the last I saw of him he was a mere speck vanishing in the shadows near the shore.

Later on I saw another mouse, while we were at work in the fields, that interested me also. This one was our native white-footed mouse. We disturbed the mother with her young in her nest, and she rushed out with her little ones clinging to her teats. A curious spectacle she presented as she rushed along, as if slit and torn into rags. Her pace was so hurried that two of the young could not keep their hold and were left in the weeds. We remained quiet, and presently the mother came back looking for them. When she had found one, she seized it as a cat seizes her kitten and made off with it. In a moment or two she came back and found the other one and carried it away. I was curious to see if the young would take hold of her teats again as at first, and be dragged away in that manner, but they did not. It would be interesting to know if they seize hold of their mother by instinct when danger threatens, or if they simply retain the hold which they already have. I believe the flight of the family always takes place in this manner with this species of mouse.

I suspect that our white-footed mouse is capable of lending a hand to a fellow in distress; at least, the following incident looks like it. One season they overran my cabin in the woods, and gave me a good deal of annoyance; so much so that I tried trapping them, using the ordinary circular trap with four or five holes and wire springs. One night I heard the trap spring in the attic over my head, followed by the kicking and straggling of the mouse. This continued for a few moments, when all was still. "There," I said, "that mouse is dead." Presently the rattling of the trap recommenced, and continued so long at short intervals that going to sleep was out of the question. I fancied the mouse was too strong for the trap, so I went upstairs to investigate. The captive was dead, sure enough, and I was more puzzled than ever. On examining him closely, I found the fur on his back was wet and much rumpled. I concluded, therefore, that his companions had seized him there, and had been tugging away at him to drag him out of the trap, causing the rattling I had heard. No other explanation seems probable.

The least mammal in our woods is the little mouse-like shrew, scarcely more than three inches long, tail and all. And it is the shyest and least known. One gets a glimpse of it only at rare intervals, while sitting or standing motionless in the woods. There is a slight rustle under the leaves, and you may see a tiny form dart across a little opening in the leafy carpet. Its one dread seems to be exposure to the light. If it were watched and waited for by a hundred enemies, it could hardly be more hurried and cautious in its movements. And when once captured and fairly exposed to the light, it soon dies, probably of fright. One night in midsummer, when I was camping in the woods, one of them got into an empty tin pail and was dead in the morning. A teacher caught one in a delusion trap, and attempted to take it to her school, to show her children, but it was dead when she got there. In winter it makes little tunnels under the snow in the woods, now and then coming to the surface, and, after a few jumps, diving under the snow again. Its tracks are like the most delicate stitching. I have never found its nest or seen its young. Like all the shrews, it lives mainly upon worms and insects.
