His plumage very soon began to show itself, crowding off tufts of the down. The quills on his great wings sprouted and grew apace. What a ragged, uncanny appearance he presented! but his look of extreme age gradually became modified. What a lover of the sunlight he was! We would put him out upon the grass in the full blaze of the morning sun, and he would spread his wings and bask in it with the most intense enjoyment. In the nest the young must be exposed to the full power of the midday sun during our first heated terms in June and July, the thermometer often going up to ninety-three or ninety-five degrees, so that sunshine seemed to be a need of his nature. He liked the rain equally well, and when put out in a shower would sit down and take it as if every drop did him good. His legs developed nearly as slowly as his wings. He could not stand steadily upon them till about ten days before he was ready to fly. The talons were limp and feeble. When we came with food he would hobble along toward us like the worst kind of a cripple, dropping and moving his wings, and treading upon his legs from the foot back to the elbow, the foot remaining closed and useless. Like a baby learning to stand, he made many trials before he succeeded. He would rise up on his trembling legs only to fall back again. One day, in the summer-house, I saw him for the first time stand for a moment squarely upon his legs with the feet fully spread beneath them. He looked about him as if the world suddenly wore a new aspect. His plumage now grew quite rapidly. One red squirrel per day, chopped fine with an axe, was his ration. He began to hold his game with his foot while he tore it. The study was full of his shed down. His dark brown mottled plumage began to grow beautiful. The wings drooped a little, but gradually he got control of them, and held them in place. It was now the 20th of July, and the hawk was about five weeks old. In a day or two he was walking or jumping about the ground. He chose a position under the edge of a Norway spruce, where he would sit for hours dozing, or looking out upon the landscape. When we brought him game he would advance to meet us with wings slightly lifted, and uttering a shrill cry. Toss him a mouse or sparrow, and he would seize it with one foot and hop off to his cover, where he would bend above it, spread his plumage, look this way and that, uttering all the time the most exultant and satisfied chuckle.
