Liberty the mocking-bird emphatically enjoyed, and at once recognized a string attached to his door as a device to deprive him of it; after vainly trying to pick it apart, he betook himself to another cage, and refused to go back to his own. In any strange cage he stood quietly while I walked up to him, and made no attempt to leave his quarters, knowing perfectly well that I did not care to shut the door upon him; but when at home I could not lift my hands, or make the slightest movement, without causing him to dart out of the cage instantly. Having contention with his room-mates about the bits of apple put out for all to enjoy, he often carried away a piece to eat at his leisure. From habit he flew first to the top of a cage, that being his favorite perching place; but he evidently appreciated that, if he dropped the morsel, he should lose it through the wires; and after looking one side and the other, plainly satisfying himself of this fact, he went to the table with it. I never before saw a bird who did not have to learn the treacherous nature of cage roofs by experience. He appeared to work things out in his mind,--to reason, in truth. One cold morning in spring, when the furnace fire was out, a large, brilliant lamp was put by his cage to take off the chill, for he felt changes keenly. He seemed to understand it at once, and though, no doubt, it was his first experience of warmth from a light, he drew as near it as possible, and remained there perfectly quiet until the sun warmed the room and it was removed. Fear, as I said, he knew not, coming freely upon the desk, or even upon my lap, after apple or bread, or anything he fancied. It was plain to see that this bird's first week with us was one of quiet study and observation. Not a movement of bird or man escaped his notice. He wished to understand, to take measure of his neighbors, to be master of the situation. This was manifested not only by his thoughtful manner and his wise and knowing looks, but by his subsequent conduct. During this period, also, he submitted to impositions from all the birds, even the smallest, without resentment. The wood-thrush easily drove him away from the apple; the little goldfinch chased him from his perch. He appeared to be meekness itself; but he was biding his time, he was making up his mind.
