He wagged his bald eyebrows at me. "You are pleased to make experiments in the ironical, I think," said he. "But I am here upon duty, I am here to discharge my errand in good faith, it is in vain you think to divert me. And let me tell you, for a young fellow of spirit and ambition like yourself, a good shove in the beginning will do more than ten years' drudgery. The shove is now at your command; choose what you will to be advanced in, the Duke will watch upon you with the affectionate disposition of a father." "I am thinking that I lack the docility of the son," says I. "And do you really suppose, sir, that the whole policy of this country is to be suffered to trip up and tumble down for an ill-mannered colt of a boy?" he cried. "This has been made a test case, all who would prosper in the future must put a shoulder to the wheel. Look at me! Do you suppose it is for my pleasure that I put myself in the highly invidious position of prosecuting a man that I have drawn the sword alongside of? The choice is not left me." "But I think, sir, that you forfeited your choice when you mixed in with that unnatural rebellion," I remarked. "My case is happily otherwise; I am a true man, and can look either the Duke or King George in the face without concern." "Is it so the wind sits?" says he. "I protest you are fallen in the worst sort of error. Prestongrange has been hitherto so civil (he tells me) as not to combat your allegations; but you must not think they are not looked upon with strong suspicion. You say you are innocent. My dear sir, the facts declare you guilty." "I was waiting for you there," said I. "The evidence of Mungo Campbell; your flight after the completion of the murder; your long course of secresy--my good young man!" said Mr. Symon, "here is enough evidence to hang a bullock, let be a David Balfour! I shall be upon that trial; my voice shall be raised; I shall then speak much otherwise from what I do to-day, and far less to your gratification, little as you like it now! Ah, you look white!" cries he. "I have found the key of your impudent heart. You look pale, your eyes waver, Mr. David! You see the grave and the gallows nearer by than you had fancied." "I own to a natural weakness," said I. "I think no shame for that. Shame . . ." I was going on. "Shame waits for you on the gibbet," he broke in. "Where I shall but be even'd with my lord your father," said I.
