“JESSE D. BRIGHT. “To His Excellency, JEFFERSON DAVIS, “_President of the Confederation of States_.” And now, before considering the letter, look well at the parties and their respective positions. It is written by a person at the time Senator, and addressed to a person at the time chief of the Rebellion, in behalf of an unknown citizen, owner of a great improvement in fire-arms. It is proper to mention, as additional facts which will not be questioned, that the author had been for a long time in notorious personal relations with the conspicuous authors of the Rebellion, especially with Jefferson Davis and John Slidell,--that he had notoriously sympathized with them in those barbarous pretensions for Slavery which constitute the Origin and Mainspring of the Rebellion,--and that he had always voted with them in the Senate. All this is notorious; and if the old maxim, _Noscitur a sociis_, or, according to our familiar English, “A man is known by the company he keeps,” be not entirely obsolete, then this inquiry must commence with a presumption against such an intimate associate of the Rebels. But, while looking at the author, we must not forget the humble citizen intrusted with the letter. It is a fact, as I understand, that he has been since arrested for treason, and is now in the hands of the law, charged with the highest crime known to justice, while the author still occupies a seat in the Senate. Perhaps this is only another illustration of the saying of Antiquity, that the law is a cobweb, holding the weak, but which the powerful break through with impunity. The agent is now in custody; the principal is yet in the Senate. So much at present with regard to the parties.
