"That is friendship. This isn't," said Dan, holding up a finger; "this is only a little bit of flesh. If it is anywhere about us, it is here;" and he took Joshua's fingers, and pressed them to his heart. Then, after a pause of a few moments, he said, "So don't cry any more because I am cutting up my crutches; I am making some new things for the birds." They had a concert after that; and the blackbird whistled "Polly, put the kettle on," to its heart's content; and the tomtit performed certain difficult acrobatic tricks in token of approval. Dan recovered so far from his sickness as to be able to leave his bed. But it almost appeared as if he was right in saying that he should not want his crutches. He had not sufficient strength in his shoulders to use them. He had to be lifted in and out of bed, and sometimes could not even wash and dress himself. Ellen Taylor was his nurse, and a dear good nurse she proved herself to be. A cross word never passed her lips. She devoted herself to the service of her helpless brother with a very perfect love; and her nature was so beautiful in its gentleness and tenderness that those qualities found expression in her face, and made that beautiful also. Dan had yielded to Joshua's entreaties not to destroy his crutches. "You might be able to use them some day," Joshua would say. To which Dan would reply by asking gayly if Joshua had ever heard of a miracle in Stepney. However, he kept his crutches, and Joshua was satisfied. In course of time Joshua began to train a few birds at his own house, and now and then Dan's parents would allow Dan to be carried to Joshua's house, and to stop there for a few days. When that occurred, Dan and Joshua slept together, and would tell stories to each other long after the candle had been blown out--stories of which Joshua was almost always the hero. Joshua had one great difficulty to overcome when he first introduced the birds into his house; that difficulty was the yellow-haired cat, of which mention has already been made. With the usual amiability of her species, the domestic tigress, directly she set eyes upon the birds, determined to make a meal of them, and it required all Joshua's vigilance to prevent the slaughter of the innocents. But he was patient, and firm, and kind, and he so conquered the tigerish propensities of the cat towards the birds, that in a few weeks she began to tolerate them, and in a few weeks more to play with them and to allow them to play with her, and gradually grew so cordial with them that it might have been supposed she had kittened them by mistake.
