The most remarkable thing connected with the history of this bird is his oven-shaped nest. It is commonly placed on the ground, under a knoll of moss or a tuft of grass and bushes, and is formed almost entirely of long grass neatly woven. It is covered with a roof of the same materials, and a round opening is made at the side, for the bird's entrance. The nest is so ingeniously covered with grass and disguised with the appearance of the general surface around it, that it is very seldom discovered. The Cow-Bunting, however, is able to find it, and often selects it as a depository for its own eggs. Those who are addicted to rambling in pursuit of natural curiosities may have observed that pine-woods are remarkable for certain collections of mosses which have cushioned a projecting rock or the decayed stump of a tree. When weary with heat and exercise, it is delightful to sit down upon one of these green velveted couches and take note of the objects immediately around us. We are then prepared to hear the least sound that invades our retreat. Some of the sweetest notes ever uttered in the wood are distinctly heard only at such times; for when we are passing over the rustling leaves, the noise made by our progress interferes with the perfect recognition of all delicate sounds. It was when thus reclining, after half a day's search for flowers, under the grateful shade of a pine-tree, now watching the white clouds that sent a brighter day-beam into these dark recesses, as they passed luminously overhead, and then noting the peculiar mapping of the grounds underneath the wood, diversified with mosses in swelling knolls, little islets of fern, and parterres of ginsengs and Solomon's-seals,--in one of these cloisters of the forest, I was first greeted by the pensive note of the Green Warbler, as he seemed to titter in supplicatory tones, very slowly modulated, "Hear me, Saint Theresa!" This strain, as I have observed many times since, is, at certain hours, repeated constantly for ten minutes at a time, and it is one of those melodious sounds that seem to belong exclusively to solitude.
