How, from this dry compound which was his only fare except an occasional worm off the rose-bushes, Bob could have wrought the surprising nobleness of spirit which he displayed about six weeks after he came to us ... is a matter which I do not believe the most expansive application of Mr. Herbert Spencer's theory of the genesis of emotion could even remotely account for. I refer to the occasion when he fairly earned the title of Sir Philip Sidney. A short time after he became our guest a couple of other fledgelings were brought and placed in his cage. One of these soon died, but the other continued for some time longer to drag out a drooping existence. One day, when Bob was about six weeks old, his usual ration had been delayed, owing to the pressure of other duties upon his attendant. He was not slow to make this circumstance known by all the language available to him. He was very hungry indeed and was squealing with every appearance of entreaty and of indignation when at last the lady of the house was able to bring him his breakfast. He scrambled to the bars of the cage--which his feeble companion was unable to do--took the proffered ball of egg-and-potato fiercely in his beak, and then, instead of swallowing it, deliberately flapped back to his sick guest in the corner and gave him the whole of it without tasting a morsel. [Illustration: "He scrambled to the bars of the cage--which his feeble companion was unable to do"] Now when Sir Philip Sidney was being carried off the battle-field of Zutphen with a fearful wound in his thigh, he became very thirsty and begged for water. As the cup was handed him, a dying soldier who lay near cast upon it a look of great longing. This Sidney observed: refusing the cup, he ordered that it should be handed to the soldier, saying, "His necessity is greater than mine." * * * * * A mocking-bird is called Bob just as a goat is called Billy or Nan, as a parrot is called Poll, as a squirrel is called Bunny, or as a cat is called Pussy or Tom. In spite of the suggestions forced upon us by the similarity of his behavior to that of the sweet young gentleman of Zutphen, our bird continued to bear the common appellation of his race and no efforts on the part of those who believe in the fitness of things have availed to change the habits of Bob's friends in this particular. Bob he was, is, and will probably remain.
