Just east of the plants I had found on Sunday, I discovered at least fifty more, withdrawn to themselves, in aristocratic exclusiveness. I lifted three of the oldest and largest plants, two of which bore large seed-pods, taking them up carefully and with plenty of soil, so as not to disturb the fibrous roots. The layer of leaf mould was loosely strewn, and not so deep here as I had expected to find it. Scarcely three inches beneath the surface, I came to a bright, whitish gravel. The spot was situated on a sloping hillside, which seemed to surround a hollow among the hills, where a glacial lake had formerly slept. It is called to-day “Chalk Pond,” the water being whitish at times in the streams flowing from the heart of the region. The soil was rich with unfathomable depths of peat and marl in the lake bed below. Peat is formed by decaying moss, ferns, and vegetable matter in general, while the marl, which lends a chalky appearance to the water and gravel, comes from the crumbling and decayed shells abounding in the soil. This loam seems to be valuable, and the pond bed is now well drained for the purpose of selling the substance as a fertilizer for lawns. White birch, chestnut, pines, and nearer the pond meadow below, beautiful elms towered skyward. From this corner I searched the hillsides to the north, along the path. At the feet of some chestnut saplings, I found the Small Round-Leaved Orchis (_Habenaria Hookeriana_). The plant was young, and apparently had not put forth blossoms this summer. They appear in early June in this region. Leaving the plant to study another year, I sought the southern hillside, and came suddenly upon a sight which I shall not soon forget. Before me stood the Great Round-Leaved Orchis (_Habenaria orbiculata_), with its two huge, round, flat-lying leaves of a soft emerald green, about eight inches long by seven wide. It bore a tall, bracted spike of greenish-white flowers,—strange, fantastic shapes, trimmed with spurs and hoods and capes. This spike of flowers rose straight up from between the two round basal leaves. It was about two feet high originally, but had been broken, doubtless by the hailstorms of June. The common names of the Round-Leaved Orchises hereabout are “Shin-plaster” and “Heal-all,” since they are applied to bruised shins, and are used as plasters for weak lungs. Thoreau, in _Maine Woods_, gives even larger dimensions of the Great Green Orchis found by him in the vicinity of Mud Pond, Moosehead and Chamberlain Carries, Maine,—where he reported it very common in July. I sat for some time admiring this weird plant; when finding that it had sown seed the former season, I decided to transport it to a garden of civilization, to see if it would take kindly to cultivation. Then I turned westward, following the sluggish yet sparkling stream down from Cold Spring. At times the stream was almost hidden by moss, through which it crept slowly.
