Again, in the fall of 1880, while the weather-wise were wagging their heads, some forecasting a mild, some a severe winter, I watched with interest for a sign from my muskrats. About November 1, a month earlier than the previous year, they began their nest, and worked at it with a will. They appeared to have just got tidings of what was coming. If I had taken the hint so palpably given, my celery would not have been frozen up in the ground, and my apples caught in unprotected places. When the cold wave struck us, about November 20, my four-legged "I-told-you-so's" had nearly completed their dwelling; it lacked only the ridge-board, so to speak; it needed a little "topping out," to give it a finished look. But this it never got. The winter had come to stay, and it waxed more and more severe, till the unprecedented cold of the last days of December must have astonished even the wise muskrats in their snug retreat. I approached their nest at this time, a white mound upon the white, deeply frozen surface of the pond, and wondered if there was any life in that apparent sepulchre. I thrust my walking-stick sharply into it, when there was a rustle and a splash into the water, as the occupant made his escape. What a damp basement that house has, I thought, and what a pity to rout a peaceful neighbor out of his bed in this weather, and into such a state of things as this! But water does not wet the muskrat; his fur is charmed, and not a drop penetrates it.
Where the ground is favorable, the muskrats do not build these mound-like nests, but burrow into the bank a long distance, and establish their winter-quarters there.
Shall we not say, then, in view of the above facts, that this little creature is weatherwise? The hitting of the mark twice might be mere good luck; but three bull's-eyes in succession is not a mere coincidence; it is a proof of skill. The muskrat is not found in the Old World, which is a little singular, as other rats so abound there, and as those slow-going English streams especially, with their grassy banks, are so well suited to him. The water-rat of Europe is smaller, but of similar nature and habits. The muskrat does not hibernate like some rodents, but is pretty active all winter. In December I noticed in my walk where they had made excursions of a few yards to an orchard for frozen apples. One day, along a little stream, I saw a mink track amid those of the muskrat; following it up, I presently came to blood and other marks of strife upon the snow beside a stone wall. Looking in between the stones, I found the carcass of the luckless rat, with its head and neck eaten away. The mink had made a meal of him.
CHEATING THE SQUIRRELS
For the largest and finest chestnuts I had last fall I was indebted to the gray squirrels. Walking through the early October woods one day, I came upon a place where the ground was thickly strewn with very large unopened chestnut burrs. On examination, I found that every burr had been cut square off with about an inch of the stem adhering, and not one had been left on the tree. It was not accident, then, but design. Whose design? The squirrels'. The fruit was the finest I had ever seen in the woods, and some wise squirrel had marked it for his own. The burrs were ripe, and had just begun to divide, not "threefold," but fourfold, "to show the fruit within." The squirrel that had taken all this pains had evidently reasoned with himself thus: "Now, these are extremely fine chestnuts, and I want them; if I wait till the burrs open on the tree, the crows and jays will be sure to carry off a great many of the nuts before they fall; then, after the wind has rattled out what remain, there are the mice, the chipmunks, the red squirrels, the raccoons, the grouse, to say nothing of the boys and the pigs, to come in for their share; so I will forestall events a little: I will cut off the burrs when they have matured, and a few days of this dry October weather will cause every one of them to open on the ground; I shall be on hand in the nick of time to gather up my nuts." The squirrel, of course, had to take the chances of a prowler like myself coming along, but he had fairly stolen a march on his neighbors. As I proceeded to collect and open the burrs, I was half prepared to hear an audible protest from the trees about, for I constantly fancied myself watched by shy but jealous eyes. It is an interesting inquiry how the squirrel knew the burrs would open if left to lie on the ground a few days. Perhaps he did not know, but thought the experiment worth trying.
The gray squirrel is peculiarly an American product, and might serve very well as a national emblem. The Old World can beat us on rats and mice, but we are far ahead on squirrels, having five or six species to Europe's one.
THE SKYLARK ON THE HUDSON
My note-book of the past season is enriched with the unusual incident of an English skylark in full song above an Esopus meadow. I was poking about a marshy place in a low field one morning in early May, when, through the maze of bird-voices,—laughter of robins, call of meadowlarks, song of bobolinks, ditty of sparrows, whistle of orioles, twitter of swallows,—with which the air was filled, my ear suddenly caught an unfamiliar strain. I paused to listen: can it be possible, I thought, that I hear a lark, or am I dreaming? The song came from the air, above a wide, low meadow many hundred yards away. Withdrawing a few paces to a more elevated position, I bent my eye and ear eagerly in that direction. Yes, that unstinted, jubilant, skyward, multitudinous song can be none other than the lark's! Any of our native songsters would have ceased while I was listening. Presently I was fortunate enough to catch sight of the bird. He had reached his climax in the sky, and was hanging with quivering wings beneath a small white cloud, against which his form was clearly revealed. I had seen and heard the lark in England, else I should still have been in doubt about the identity of this singer. While I was climbing a fence I was obliged to take my eye from the bird, and when I looked again the song had ceased and the lark had gone. I was soon in the meadow above which I had heard him, and the first bird I flushed was the lark.
How strange he looked to my eye (I use the masculine gender because it was a male bird, but an Irishman laboring in the field, to whom I related my discovery, spoke touchingly of the bird as "she," and I notice that the old poets do the same); his long, sharp wings, and something in his manner of flight suggested a shore-bird. I followed him about the meadow and got several snatches of song out of him, but not again the soaring, skyward flight and copious musical shower. By appearing to pass by, I several times got within a few yards of him; as I drew near he would squat in the stubble, and then suddenly start up, and, when fairly launched, sing briefly till he alighted again fifteen or twenty rods away. I came twice the next day and twice the next, and each time found the lark in the meadow or heard his song from the air or the sky. What was especially interesting was that the lark had "singled out with affection" one of our native birds, and the one that most resembled its kind, namely, the vesper sparrow, or grass finch. To this bird I saw him paying his addresses with the greatest assiduity. He would follow it about and hover above it, and by many gentle indirections seek to approach it. But the sparrow was shy, and evidently did not know what to make of her distinguished foreign lover. It would sometimes take refuge in a bush, when the lark, not being a percher, would alight upon the ground beneath it. This sparrow looks enough like the lark to be a near relation. Its color is precisely the same, and it has the distinguishing mark of the two lateral white quills in its tail. It has the same habit of skulking in the stubble or the grass as you approach; it is exclusively a field-bird, and certain of its notes might have been copied from the lark's song. In size it is about a third smaller, and this is the most marked difference between them. With the nobler bipeds, this would not have been any obstacle to the union, and in this case the lark was evidently quite ready to ignore the difference, but the sparrow persisted in saying him nay. It was doubtless this obstinacy on her part that drove the lark away, for, on the fifth day, I could not find him, and have never seen nor heard him since. I hope he found a mate somewhere, but it is quite improbable. The bird had, most likely, escaped from a cage, or, maybe, it was a survivor of a number liberated some years ago on Long Island. There is no reason why I the lark should not thrive in this country as well as in Europe, and, if a few hundred were liberated in any of our fields in April or May, I have little doubt they would soon become established. And what an acquisition it would be! As a songster, the lark is deserving of all the praise that has been bestowed upon him. He would not add so much to the harmony or melody of our bird-choir as he would add to its blithesomeness, joyousness, and power. His voice is the jocund and inspiring voice of a spring morning. It is like a ceaseless and hilarious clapping of hands. I was much interested in an account a friend gave me of the first skylark he heard while abroad. He had been so full of the sights and wonders of the Old World that he had quite forgotten the larks, when one day, as he was walking somewhere near the sea, a brown bird started up in front of him, and mounting upward began to sing. It drew his attention, and as the bird went skyward, pouring out his rapid and jubilant notes, like bees from a hive in swarming-time, the truth suddenly flashed upon the observer.
"Good heavens!" he exclaimed, "that is a skylark; there is no mistaking that bird."
