Now, far away in the woods a bird called; another answered; presently the hammering of a woodpecker was heard. gradually the cool dim gray of the morning whitened, and as gradually sounds multiplied and life manifested itself. the marvel of nature shaking off sleep and going to work unfolded itself to the musing boy. a little green worm came crawling over a dewy leaf, lifting two-thirds of his body into the air from time to time and "sniffing around," then proceeding again—for he was measuring, tom said; and when the worm approached him, of its own accord, he sat as still as a stone, with his hopes rising and falling, by turns, as the creature still came toward him or seemed inclined to go elsewhere; and when at last it considered a painful moment with its curved body in the air and then came decisively down upon tom's leg and began a journey over him, his whole heart was glad now a procession of ants appeared, from nowhere in particular, and went about their labors; one struggled manfully by with a dead spider five times as big as itself in its arms, and lugged it straight up a tree-trunk. a brown spotted lady-bug climbed the dizzy height of a grass blade, and tom bent down close to it and said, "lady-bug, lady-bug, fly away home, your house is on fire, your children's alone," and she took wing and went off to see about it—which did not surprise the boy, for he knew of old that this insect was credulous [trusting] about conflagrations [fires], and he had practised upon its simplicity more than once. a tumblebug came next, heaving sturdily at its ball, and tom touched the creature, to see it shut its legs against its body and pretend to be dead. the birds were fairly rioting by this time. a catbird, the northern mocker, lit in a tree over tom's head, and trilled out her imitations of her neighbors in a rapture of enjoyment; then a shrill jay swept down, a flash of blue flame, and stopped on a twig almost within the boy's reach, cocked his head to one side and eyed the strangers with a consuming curiosity; a gray squirrel and a big fellow of the "fox" kind came skurrying along, sitting up at intervals to inspect and chatter at the boys, for the wild things had probably never seen a human being before and scarcely knew whether to be afraid or not. all nature was wide awake and stirring, now; long lances of sunlight pierced down through the dense foliage far and near, and a few butterflies came fluttering upon the scene.
