But I hear the suggestion, that at the date of this letter war was not yet flagrant, and that the author did not anticipate an actual conflict of arms. The first part of this suggestion is notoriously false. War had already begun, in the seizure of forts, and in the muster of Rebel armies; nay, more, in the very presence of the author, the gage of battle was flung down on this floor by Senators leaving to take part in the Rebellion. This has been unanswerably shown by the Senator from Minnesota [Mr. WILKINSON]. But the second part of the suggestion attributes to the author an ignorance of the well-known condition of things, inconsistent with his acknowledged intelligence. If the progress and development of the Rebellion had been in secret, if it had been masked by an impenetrable privacy, if it had been shrouded in congenial darkness, then this apology might be entitled to attention. But the Rebellion was open and complete; and on the 1st of March it was armed from head to foot, and in battle array against the National Government. Such was the actual condition of things, patent, certain, conspicuous to the whole country. And permit me to say that any apology now offered on pretext of ignorance shows simply a disposition to evade a just responsibility at any hazard of personal character. I note the further suggestion, that the letter was written in carelessness, or in heedlessness, if you please, and without treasonable intent. Of course such a suggestion must be futile; for every man is presumed to know the natural consequences of his conduct. This is the rule of law, and the rule of patriotism. No man can be admitted to set up any carelessness or heedlessness as apology for treason. And I doubt not you will all agree with me, that a patriot Senator cannot be careless or heedless, when his country is in peril. But I catch yet another suggestion, that this letter is trivial and insignificant to justify the condemnation of a Senator. Then, indeed, is disloyalty trivial; then is treason itself trivial. It is true, the letter is curt; it contains a single short paragraph only; but I have yet to learn that crime is measured by paragraphs or sentences, and that treason may not be found in a few words as well as in many. True, also, the letter is familiar in tone; but treason is a subtle wickedness, which sometimes stalks in state and sometimes shuffles in homely disguise. It is our duty to detect and to judge it, whatever form it takes. * * * * *
