We cannot consent to be drawn, as the Unionist seems desirous that we should be, into a lengthened controversy upon its favorite topic. The whole matter lies in a nut-shell, and the editor knows, or ought to know, what is the real matter in dispute—when confined to that there is but little to be said on his side of the subject. It is only by multiplying words, and turning off the attention from the true merits of the debate, that the abolitionists can hope to obtain a hearing. No better evidence is wanted of the weakness of the cause than the confessions of the Genius of Temperance, that Abolition cannot hope to succeed without the destruction of the Colonization Society. That Society has effected the emancipation of many slaves, whereas abolitionism has not yet freed one. By their fruits ye shall know them. Let us suppose a [..]se—not a very probable one, it must be confessed, yet if the abolitionists are to be believed they expect to see a part, at least, of it fulfilled—and are laboring to bring it about—Suppose that every person north of the Potomac and the Ohio rivers became an abolitionist—as dedicated and fierce as Garrison himself—that those who are south of this line remain just as they are—some few honorable to the Colonization Society, here and there one [..]ling and anxious to be rid of his slaves, but the great majority desirous to retain them. Now supposing such a […]e of public opinion—and with the Constitution directly in their teeth, what course, we ask, would the abolitionists most probably pursue? If they answer, we do not know, then they are laboring without any definite views—and if they do know, we should be very glad to be informed. The Unionist has rather inflated (and probably mistaken) notions of its own importance. It brags of being admitted to the private counsels of the leaders, which we must be permitted to doubt. The Unionist is too young to be initiated into all the secrets of the sect. Doubtless when Garrison, or his worthy friend from New York, passes along this way, they pat the Editor on the head—call him a nice little fellow—let him know some of the least important of their plans—tell him to be a good boy, and, by the bye, he shall know more—and anon his vanity makes him believe he is in their full confidence. As you would avoid disappointment, do not trust it too strongly.

The Unionist must excuse us from further notice for the present, and probably for some time to come. Congress meet this week, and some very important subjects will be brought up for discussion. We wish to listen, and, if possible, learn something of their merits.
