To-day, however, my mood was less Sundayish than before, and in spite of the heat I ventured across an open pasture,--where a Bachman's finch was singing an ingenious set of variations, and a rabbit stamped with a sudden loudness that made me jump,--and then through a piece of wood, till I came to another hollow like the one I had left, but without water, and therefore less thickly shaded. Here was the inevitable thicket of brambles (since I speak so much of chats and indigo-birds, the presence of a sufficiency of blackberry bushes may be taken for granted), and I waited to see what it would bring forth. A field sparrow sang from the hillside,--a sweet and modest tune that went straight to the heart, and had nothing to fear from a comparison with Bachman's finch or any other. What a contrast in this respect between him and his gentle-seeming but belligerent and tuneless cousin whom we call "chippy."[1] Here, likewise, were a pair of complaining Carolina wrens and an Acadian flycatcher. A thrush excited my curiosity, having the look of a gray-cheek, but showing a buff eye-ring; and while I was coaxing him to whistle, and so declare himself,--often a ready means of identification, and preferable on all accounts to shooting the bird,--there came a furious outburst from the depths of the brier patch, with a grand flurry of wings: a large bird and two smaller ones engaged in sudden battle, as well as I could make out. At the close of the _mêlée_, which ended as abruptly as it had begun, the thicket showed two wrens, a white-throated sparrow, and a female cardinal. The cardinal flew away; the affair was no business of hers, apparently; but in a minute she was back again, scolding. Then, while my back was turned, everything became quiet; and on my stepping up to reconnoitre, there she sat in her nest with four eggs under her. At that moment a chat's loud voice was heard, and, turning quickly, I caught the fellow in the midst of a brilliant display of his clownish tricks, ridiculous, indescribable. At a little distance, it is hard to believe that it can be a bird, that dancing, shapeless thing, balancing itself in the air with dangling legs and prancing, swaying motions. Well, that is the chat's way. What more need be said? Every creature must express himself, and birds no less than other poets are entitled to an occasional "fine frenzy." My little excursion had brought me nothing new, and, like all my similar ventures on Missionary Ridge, it ended in defeat. The sun was too much for me; to use a word suggested by the place, it carried too many guns. I took a long and comfortable siesta under a magnificent chestnut oak. Then it was near noon, and, with my umbrella spread, I mounted the hill to the railway, and waited for a car. FOOTNOTE: [1] If I could have my way, he should be known as the doorstep sparrow. The name would fit him to a nicety. LOOKOUT MOUNTAIN.
