“No. What would the Doctor say?”

“He never should know. We’d never tell, either of us, would we, Burr?”

“Never!” I cried.

“I believe you, boys, that I do,” said the old man; “and it was never forbidden. Never even mentioned,” he continued thoughtfully. “I should like to oblige an old soldier’s son.”

“And I mean to be an army surgeon,” said Mercer.

“And you couldn’t do better, my lad.”

“Then you’ll teach us?” cried Mercer, and I hung upon his answer, with the spirit of retaliation strong within me now.

“Do you know what it means, my lads? Deal of knocking about.”

“We don’t care how much, do we, Burr?”

“No,” I cried excitedly. “You may knock me down hundreds of times, if you’ll teach me how to knock you down.”
