Henry David ThoreauThe hounding of a dog pursuing a fox or other animal in the horizon may have first suggested the notes of the hunting-horn to alternate with and relieve the lungs of the dog. This natural bugle long resounded in the woods of the ancient world before the horn was invented.
Henry David ThoreauThe poet's, commonly, is not a logger's path, but a woodman's. The logger and pioneer have preceded him, like John the Baptist; eaten the wild honey, it may be, but the locusts also; banished decaying wood and the spongy mosses which feed on it, and built hearths and humanized Nature for him.
