The little captive was very happy for a few hours, flying about the "wild garden" in the rear of the house--a few square rods where more than 400 varieties of native plants were growing. It was not long, however, before a homesick longing replaced the new happiness and the bird returned to the cage which was left upon the piazza roof. The next morning the second sparrow was given his freedom. Nothing was seen of him for a week, when he came to the window, beat his tired wings against the pane, and sank down upon the window sill so overjoyed at finding himself at home that he was fairly bursting with song. His throat trembled with the ecstasy; the feathers ruffling as the melody rose from his heart and deluged the air with sweetness. His joy was too complete for further experiment. The first sparrow was again released only to return at nightfall and go promptly to bed at the general retiring hour. This hour, by the way, varied indefinitely; the whole aviary accommodating their hours to those of their master, rising with him and settling for the night as he turned off the gas. After this same bird was repeatedly sent out, like Noah's dove, coming home at evening, till after many days it came no more--an implicit confidence in the rightness of all intention doubtless making it an easy prey to some evil design. A handsome hermit thrush from the same aviary, domesticated in my room, after an hour or two "abroad" is as homesick for his cage as is a child for its mother. When this bird came into my possession his open and discourteous disapproval of women was humiliating. His attitude was not simply endurance but open revolt, a deep-rooted hatred for the entire sex. When, after long weeks of acquaintance, this hostility was overcome he followed me about the room, stood beside me at my work, and has since been unchanging in a pathetic devotion. He plants his tiny feet in my pen-tray and throws the pens upon the floor. He stands on tiptoe before the mirror, staring with curious eyes at the strange rival till awe is replaced by anger and the brown wings beat in unavailing effort to reach the insolent mimic. When shown a worm he trembles in excited anticipation, his little feet dancing upon the floor, his wings moving rapidly, while he utters a coaxing, entreating syllable. The song is sweetest when raindrops fall or when the room is noisy and confused. I notice, too, that he is more tuneful before a rain. I must confess that he keeps late hours, that he is often busy getting breakfast when orthodox birds should be dreaming, his active periods being liable to fall at any hour of the night, more especially if there be a moon. An intensely sentimental nature may be unable to sleep when the beauty of the world is so strongly emphasized. His last frolic was with a frog the children smuggled into the house, chasing it around the room, darting at it with wide-open beak, advancing and retreating in a frenzied merriment.
