_Friday, October 22._--A continued succession of unpleasant, Novembery days, and Autumn has made rapid progress in the work of decay. It is now somewhat of a rare good fortune to find a verdant, grassy spot, on some slope, or in a dell; and even such seldom-seen oases are bestrewn with dried brown leaves,--which, however, methinks, make the short, fresh grass look greener around them. Dry leaves are now plentiful everywhere, save where there are none but pine-trees. They rustle beneath the tread, and there is nothing more autumnal than that sound. Nevertheless, in a walk this afternoon I have seen two oaks which retained almost the greenness of summer. They grew close to the huge Pulpit Rock, so that portions of their trunks appeared to grasp the rough surface; and they were rooted beneath it, and, ascending high into the air, overshadowed the gray crag with verdure. Other oaks, here and there, have a few green leaves or boughs among their rustling and rugged shade. Yet, dreary as the woods are in a bleak, sullen day, there is a very peculiar sense of warmth and a sort of richness of effect in the slope of a bank and in sheltered spots, where bright sunshine falls, and the brown oaken foliage is gladdened by it. There is then a feeling of comfort, and consequently of heart-warmth, which cannot be experienced in summer. I walked this afternoon along a pleasant wood-path, gently winding, so that but little of it could be seen at a time, and going up and down small mounds, now plunging into a denser shadow and now emerging from it. Part of the way it was strewn with the dusky yellow leaves of white-pines,--the cast-off garments of last year; part of the way with green grass, close-cropped and very fresh for the season. Sometimes the trees met across it; sometimes it was bordered on one side by an old rail-fence of moss-grown cedar, with bushes sprouting beneath it, and thrusting their branches through it; sometimes by a stone wall of unknown antiquity, older than the wood it closed in. A stone wall, when shrubbery has grown around it, and thrust its roots beneath it, becomes a very pleasant and meditative object. It does not belong too evidently to man, having been built so long ago. It seems a part of nature. Yesterday I found two mushrooms in the woods, probably of the preceding night's growth. Also I saw a mosquito, frost-pinched, and so wretched that I felt avenged for all the injuries which his tribe inflicted upon me last summer, and so did not molest this lone survivor. Walnuts in their green rinds are falling from the trees, and so are chestnut-burrs. I found a maple-leaf to-day, yellow all over, except its extremest point, which was bright scarlet. It looked as if a drop of blood were hanging from it. The first change of the maple-leaf is to scarlet; the next, to yellow. Then it withers, wilts, and drops off, as most of them have already done. * * * * *
