While sitting at my post of observation, my neck sometimes refused to retain its unnatural position a moment longer, and then I refreshed myself with other objects around; for after some search I had found a charming place for study. It was beside a rocky ledge which ran through the middle of a bit of meadow-land, and happily defied being cultivated, although it supported a flourishing crop of wildings,--scattering elm, oak, and pine trees, with sumac, goldenrod, and other sweet things to fill up the tangle. Under a low-spreading tree I placed my seat: at my back the screening rocks, in front a strip of meadow waiting for the mower. Along the side where I entered ran a stone wall, but before me was a stretch of delightfully dilapidated old board and pole fence. It had been reinforced and made available for keeping out undesirables by barbed wire, but at my distance that was inconspicuous and did not disturb me. The fence had never been painted, the wind and weather of many years had toned it down to the hue of a tree-trunk, and it was so thoroughly decorated with lichens that it had come to look almost like a bit of nature's work,--if nature could have made anything so ugly. I believe the birds regarded it as a special arrangement for their benefit. Certainly they used it freely.
But beyond the fence was a genuine bit of nature's handiwork in which man had no part: an extended and luxuriant tangle, bordering the river, of alder and other bushes, with here and there a young tree, elm, apple, cedar, or wild cherry; and winding through it a bewitching path, made by cows in their unconventional and meandering style and for their own convenience, penetrating every charming nook in the shrubbery, and so unnoticeable at its entrance that one might pass it and not suspect its presence. In this path bushes met over their heads, often not high enough for ours, wild roses perfumed the air, and meadow-sweet lingered long after it was gone from haunts less cool and shaded. Every turn offered a new and fascinating picture, and a stroll through the irresistible way always began or ended my day's study.
For several days following my happy discovery I spent much time watching domestic affairs in the poplar-tree. The little matron was not a steady sitter. From two to four minutes, at intervals of about the same length, was as long as she could possibly remain in one place; and even then she entertained herself by rearranging the materials composing her nest, till I began to fear she would have it pulled to pieces before the birdlings appeared. Beautiful beyond words was her manner of entering and leaving her snug home. On departing, she simply spread her wings and floated off, as if lifted by the rising tide of an invisible element; and on returning, she sank from a height of ten or twelve inches, as if by the subsidence of the same tide.
