Allow me, though a stranger, to thank you in the name of Humanity for the noble speech on the ‘Barbarism of Slavery’ just delivered by you in the Senate, so just, so truthful, and so timely.

I rejoice that not alone on political grounds do you attack the system.

It seems to me that he is but an ill observer of the signs of the times, and has not his finger upon the nation’s pulse, who fails to perceive that the day of soft words and bated breath and candy-tongued conciliation is gone, and gone…

Slavery has seen its last triumph, and henceforth should receive no quarter.

It is the best arranged and by far the most complete exposure of the horrid rite of Slavery to be found within the same compass in any language, so far as known.

It is the most valuable Antislavery document that I have ever seen.

It is solid with fact, eloquence, and courage,--right in matter, place, and time.

It takes the only true ground,--the essential barbarism and sinfulness of Slavery.

You must permit me, a perfect stranger, to express my cordial thanks to you for the noble, scathing speech on the ‘sum of villanies’ with which you enriched our literature on Monday last in the Senate.

This contest is no holiday battle, but the irrepressible conflict between Right and Wrong.

I thank my God that he has spared your life to tell the world that the bludgeon of Barbarism did not silence your tongue nor subdue your spirit. ‘Let the Heathen rage.’ Behind you stand a million of your fellow-citizens in whose hearts…

I hold Slavery to be a curse and a disgrace to our country and to mankind; and I rejoice to know that we have one man who is not afraid to denounce it as such, in plain Anglo-Saxon, on the floor of the Senate, and in the face of the…

Massachusetts can afford to let one of her Senatorial chairs remain vacant, if we can have such a speech as that once in four years.

I feel like thanking God from the bottom of my heart that you have been restored to health, and have the nerve, or, as you once expressed yourself, the ‘backbone,’ to stand as one of God’s noblemen and give utterance to truth.

There is not brass enough, nor yet iron, nor steel, in the Southern Senators to ward off such a blow.

As you undertook to give the truth, why not tell the whole truth?

It is time they were exposed; it is time to hold up Slavery’s mirror, not only to the South, but before the world.

The efforts of many noble patriots have been manly, self-denying, and praiseworthy, and should not be disparaged; and yet I know of no one who has taken the high moral ground on this subject which you have from the first.

It is a godlike effort, a stunning blow, a blow in the right direction and upon the right spot, which has inflicted a fearful, if not a deadly wound.… I pray God that you may live, and retain your place, to pronounce the funeral oration of…

I think your speech will long be referred to, as embracing all that has been and well can be said on this question, and forever cause men to wonder why it was listened to in silence.

I take pleasure in saying that in my opinion your recent effort ranks with Demosthenes on the Crown, and with Burke on Warren Hastings.

Nobly and well have you met the expectations of those who, like myself, have waited through four years of silence for your next utterance on the great sin of our times.

Highly as I prize the speech, I think your brief and pointed reply to Senator Chesnut fully doubles its value, for all practical purposes.

We never can reach the evil as long as we fight on the defensive.

Let us at all hazards prevent the extension of Slavery and the increase of the Slave Power.
