The trick of the apologists has been, by stringent application of technical rules, to shut out all except offences charged, and then, when stress was laid upon these offences, to cry out that at most they were only technical, and too trifling for impeachment. To satisfy lawyers, the House weakly declined to act on the bloody transgressions of two years, but sought to provide against the future. Like the Roman ambassadors, they traced a line about the offender, which he was not to pass except at peril. This was the line of law. At last he passed the line, openly, knowingly, defiantly; and now that he is arraigned, we are told that this plain offence is nothing, only a little technicality. One of the counsel at the bar, [Mr. GROESBECK,] in a speech which showed how much feeling and talent could be given to a wrong side, exclaimed:-- “It almost shocks me to think that the President of the United States is to be dragged out of his office on these miserable little questions whether he could make an _ad interim_ appointment for a single day.” Only by excluding the whole context and all its antecedents could the question be reduced to this trivial form; and yet, even thus reduced, it involved nothing less than the supremacy of the laws. I know not how such a question can be called “trifling.” Often a great cause is presented on a narrow issue: as when English liberty was argued on the claim of ship-money, which was a tax of a few shillings only. Behind this question, called trifling by the kingly apologists of that day, loftily stood the great cause of the People against Prerogative, being the same now pending before the Senate. That other cause, on which at a later day hung the destinies of this continent, was presented on a narrower issue still. There was a tax of threepence a pound on tea, which our fathers refused to pay. But behind this question, so trifling to the apologists of prerogative, as behind that of ship-money, stood loftily the same great cause. The first cost Charles the First his head. The second cost George the Third his colonies. If such a question can be disparaged as of small moment, then have the martyred dead in all times suffered in vain, then was the costly blood lavished for the suppression of our Rebellion an empty sacrifice.
