_Nov. 25._ I feel a little alarmed when it happens that I have walked a mile into the woods bodily, without getting there in spirit. I would fain forget all my morning’s occupation, my obligations to society. But sometimes it happens that I cannot easily shake off the village; the thought of some work, some surveying, will run in my head, and I am not where my body is, I am out of my senses. In my walks I would return to my senses like a bird or a beast. What business have I in the woods, if I am thinking of something out of the woods?[97] This afternoon, late and cold as it is, has been a sort of Indian summer. Indeed, I think that we have summer days from time to time the winter through, and that it is often the snow on the ground makes the whole difference. This afternoon the air was indescribably clear and exhilarating, and though the thermometer would have shown it to be cold, I thought that there was a finer and purer warmth than in summer; a wholesome, intellectual warmth, in which the body was warmed by the mind’s contentment. The warmth was hardly sensuous, but rather the satisfaction of existence. I found Fair Haven skimmed entirely over, though the stones which I threw down on it from the high bank on the east broke through. Yet the river was open. The landscape looked singularly clean and pure and dry, the air, like a pure glass, being laid over the picture, the trees so tidy, stripped of their leaves; the meadows and pastures, clothed with clean dry grass, looked as if they had been swept; ice on the water and winter in the air, but yet not a particle of snow on the ground. The woods, divested in great part of their leaves, are being ventilated. It is the season of perfect works, of hard, tough, ripe twigs, not of tender buds and leaves. The leaves have made their wood, and a myriad new withes stand up all around pointing to the sky, able to survive the cold. It is only the perennial that you see, the iron age of the year. These expansions of the river skim over before the river itself takes on its icy fetters. What is the analogy? I saw a muskrat come out of a hole in the ice. He is a man wilder than Ray or Melvin. While I am looking at him, I am thinking what he is thinking of me. He is a different sort of a man, that is all. He would dive when I went nearer, then reappear again, and had kept open a place five or six feet square so that it had not frozen, by swimming about in it. Then he would sit on the edge of the ice and busy himself about something, I could not see whether it was a clam or not. What a cold-blooded fellow! thoughts at a low temperature, sitting perfectly still so long on ice covered with water, mumbling a cold, wet clam in its shell. What safe, low, moderate thoughts it must have! It does not get on to stilts. The generations of muskrats do not fail. They are not preserved by the legislature of Massachusetts. Boats are drawn up high which will not be launched again till spring.
