As I return to the bed of the valley, a female cardinal grosbeak flutters suspiciously about a thicket of tall blackberry vines. Her nest should be there, I think, but a hasty look reveals nothing. Again I come upon the Canadian warbler. If there is only one here, he is often in my way. I sit down upon the leaning, almost horizontal, bole of a large tupelo,--a new tree to me, but common in this country. The thick dark-colored bark is broken deeply into innumerable geometrical figures, giving the tree a noticeable, venerable appearance, as wrinkles lend distinction and character to an old man's face. Another species, which, as far as I can tell, should be our familiar tupelo of Massachusetts, is equally common,--a smaller tree, with larger leaves. The moisture here, slight as it now is, gives the place a vegetation of its own and a peculiar density of leafage. From one of the smaller tupelos (I repeat that word as often as I can, for the music of it) cross-vine streamers are swinging, full of red-and-yellow bells. Scattered thinly over the ground are yellow starflowers, the common houstonia, a pink phlox, and some unknown dark yellow blossom a little like the fall dandelion,--Cynthia, I guess. My thoughts are recalled by a strong, sharp _chip_ in a voice I do not recognize,--a Kentucky warbler's, as presently turns out. He walks about the ground amid the short, thin grass, seemingly in the most placid of moods; but at every few steps, for some inscrutable reason, he comes out with that quick, peremptory call. And all the while I keep saying to myself, "What a beauty!" But my forenoon is past. I rise to go, and at the motion he takes flight. Near the spring the goldfinches are still in full chorus, and just beyond them in the path is a mourning dove. That was a good season: hymns without words, "a sermon not made with hands," and the world shut out. Three days afterward, fast as my vacation was running away, I went to the same place again. The olive-backed thrushes were still singing, to my surprise, and the Kentucky warblers were still feeding in the grass. The scarlet tanager sang (it is curious how much oftener I mention him than the comparatively unfamiliar, but here extremely common summer tanager), the cuckoo called, the Acadian flycatcher was building her nest,--on a horizontal limb of a maple,--and a goldfinch warbled as if he could never cease. A veery sang, also (I heard but one other in Tennessee), with a chestnut-sided warbler, two redstarts (one of them in the modest garb of his mother), a Carolina chickadee, a mocking wren, a pine warbler, a prairie warbler, and a catbird. In time, probably, all the birds for a mile around might have been heard or seen beside that scanty rill.
