LOCKPORT, April 15, 1854.

DEAR DOUGLASS:—A number of times I thought I must write a few lines for your paper, but from one cause or another I put it off. My remarks will be short and dissultory.

When Garrison & Co were flagilating [sic] you, I felt like talking; however, you passed thro' that ordeal without needing a helping hand, especially from one so feeble as the writer.—Partdon me, when I say in some respects, I consider it a happy occurence, in thoroughly convincing you, and the community at large, that they are a peculiar class of proscriptionists, uniting in their efforts to annihilate any and every person who dare differ with them in sentiment, or use any instrumentality not according with their notions. However, in one respect, they show themselves Democratic; they neither spare white or black, bond or free. All who do not subscribe to the Anti-Slavery Divinity of their Society, are pro-slavery infidels. I sometimes think it is well they have banded together, to talk against slavery; for if such characters happened to be slaveholders, Legree would be outrivalled.

When that Irish slaveholder, Mitchel, was receiving a merited castigation from the press, I felt like putting on the lash. I now think the less his putrid carcass is disturbed, the better.

A few words with regard to the slavery question. The agitation in Congress on the repeal of the Missouri Compromise, is waking up the North. I fear it will not be lasting. The slave power has not yet thoroughly and understandingly touched the Northern conscience. That conscience lies in the pocket. When that is rifled, then will the people of the North wake up? A mighty conversion will follow. The sin of slavery will be spoken of in plain language. Such speeches as yours will then be considered of rather the dough-faced order; then it will be war to the knife, and the knife to the hilt. Touch a Yankee's pocket and you insult his God, and then his prayers, ballots—yes, and even his blood will cry atone, atone, ATONE!

From present appearances, I think the Hunkers and Silvers intend going together next fall. The Seward Whigs intend holding on to the old Whig party; and their game is to nominate Wm. H. Seward for Governor, expecting by so doing to sop up the Free Democratic vote. It is an old saying, and true as old, to be forewarned is to be fore-armed. The Whig Party out of power at the North always make strong anti-slavery professions; but in power, even with their abolition Fillmore at their head, they go slavery to the dregs. Now, it is out of no love to Seward that he will be nominated. No, no. He has been too anti slavery for national Whiggery in the Senate, therefore he must not be sent again; but he will answer to make a stool pigeon of to bring anti-slavery men to the Whig party. A man of the calibre of ex-Governor Hunt (if not himself) must go to the Senate. This is the ordeal through which the Free Democrats are to pass next fall. Some, perhaps, will be deceived, thinking by voting for Mr. Seward, they will be helping the cause of freedom—when in reality, it is far otherwise, as the object of the wire pullers is to send a more malable [sic] tool to the Senate, and destroy the anti-slavery cause in the State.

I wish, dear Douglass, you would keep an eye to this matter, for I have no doubt such a project is now in embryo.

JOHN ROBERTS.
