Mark did as he was bid, and the doctor drew up a chair and sat down by him to examine the defective joint. The boy's black eyes were fixed with a searching gaze on the doctor's face, as if to read his thoughts, but there was nothing to be derived from the grave, sphinx-like countenance. The eager, inquisitive look of the lad, however, did not escape the physician's notice. "What is your name, my boy?" inquired the doctor. "Mark Gildersleeve, sir." "Ah, you're Mr. Gildersleeve the iron-master's son, are you?" "No, sir, his brother." "His brother, eh! Who attended you when you received the injury?" "Dr. Pokemore, sir." "Dr. Pokemore, eh! He is your brother's family physician, is he not?" "Yes, sir." "Who sent you to me?" "No one, sir. I came myself." "Why did you not go to Dr. Pokemore?" "Because he said I could not be cured." The doctor after some reflection gave a doubtful nod, and said, "If anything can be done it will only be after a painful operation." "I'll stand anything, doctor, if you will only cure me. You may cut me, or do anything you like, only make me walk like other boys." The doctor took from a case of surgical instruments a bright bistoury, which he caused to glitter before the boy's eyes, as he felt its edge. A plucky little fellow, thought the doctor, (struck by the unflinching look of determination in the boy's countenance,) and seems to be in earnest. "You say that you have been this way from infancy; why are you so anxious to be helped now?" "Because--because--they worry me about it," replied Mark. "Worry you--that's very unkind. Come, tell me all about it. I suspect there's a little history behind this, and you must make me your confidant." Led on by the doctor's kind way, Mark exposed the wound his pride had received; related the story of his fight with Jack Heath (omitting, however, any mention of Edna's interference), and again begged the doctor to remove the impediment in his walk, asserting his willingness to submit to any operation, however painful, that might be deemed necessary to effect the object. Pleased with the boy's frankness and resolution, and desirous to help him, the doctor again examined the maimed ankle. A slow, fixed pursing of his lips expressed doubt, and the boy's countenance fell. There was a glimpse of hope, though, in the doctor's words, who told Mark that although he could not say anything encouraging now, he would talk the matter over with his (Mark's) brother, "And if he is willing, I will take you to New York with me, where we can consult the best skill, and if there be a probability of helping you, it shall be done." A fine head, thought the doctor, passing his hand over Mark's broad forehead; there should be something there. "Stop a bit, Mark; what do you intend to be when you grow up, my boy?" "I don't know, sir." "What would you like to be, then?" "I'd like," replied Mark, after some hesitation, "I think--I'd like to be a hero."
