Unclosing our hands a small space, out popped the little head with a pair of round brilliant eyes. Then we bethought ourselves of feeding him, and forthwith prepared him a stiff glass of sugar and water, a drop of which we held to his bill. After turning his head attentively, like a bird who knew what he was about and didn't mean to be chaffed, he briskly put out a long, flexible tongue, slightly forked at the end, and licked off the comfortable beverage with great relish. Immediately he was pronounced out of danger by the small humane society which had undertaken the charge of his restoration, and we began to cast about for getting him a settled establishment in our apartment. I gave up my work-box to him for a sleeping-room, and it was medically ordered that he should take a nap. So we filled the box with cotton, and he was formally put to bed with a folded cambric handkerchief round his neck, to keep him from beating his wings. Out of his white wrappings he looked forth green and grave as any judge with his bright round eyes. Like a bird of discretion, he seemed to understand what was being done to him, and resigned himself sensibly to go to sleep. The box was covered with a sheet of paper perforated with holes for purposes of ventilation; for even humming-birds have a little pair of lungs, and need their own little portion of air to fill them, so that they may make bright scarlet little drops of blood to keep life's fire burning in their tiny bodies. Our bird's lungs manufactured brilliant blood, as we found out by experience; for in his first nap he contrived to nestle himself into the cotton of which his bed was made, and to get more of it than he needed into his long bill. We pulled it out as carefully as we could, but there came out of his bill two round, bright, scarlet, little drops of blood. Our chief medical authority looked grave, pronounced a probable hemorrhage from the lungs, and gave him over at once. We, less scientific, declared that we had only cut his little tongue by drawing out the filaments of cotton, and that he would do well enough in time,--as it afterward appeared he did,--for from that day there was no more bleeding. In the course of the second day he began to take short flights about the room, though he seemed to prefer to return to us,--perching on our fingers or heads or shoulders, and sometimes choosing to sit in this way for half an hour at a time. "These great giants," he seemed to say to himself, "are not bad people after all; they have a comfortable way with them; how nicely they dried and warmed me! Truly a bird might do worse than to live with them." So he made up his mind to form a fourth in the little company of three that usually sat and read, worked and sketched, in that apartment, and we christened him "Hum, the son of Buz." He became an individuality, a character, whose little doings formed a part of every letter, and some extracts from these will show what some of his little ways were.
