The society's one motive "to get rid of the free people of color," was outrageous enough, but this was not its only sin. There was another phase to the mischief it was working, which lifted it to the rank of a great sinner. It was not only harmful in its principles and purposes. "It imperatively and effectually seals up the lips," so Garrison accused it, "of a vast number of influential and pious men, who, for fear of giving offence to those slaveholders with whom they associate, and thereby leading to a dissolution of the compact, dare not expose the flagrant enormities of the system of slavery, nor denounce the crime of holding human beings in bondage. They dare not lead to the onset against the forces of tyranny; and if they shrink from the conflict, how shall the victory be won? I do not mean to aver that in their sermons, or addresses, or private conversations, they never allude to the subject of slavery; for they do so frequently, or at least every Fourth of July. But my complaint is that they content themselves with representing slavery as an evil—a misfortune—a calamity which has been entailed upon us by former generations,—and not as an individual CRIME, embracing in its folds, robbery, cruelty, oppression, and piracy. They do not identify the criminal; they make no direct, pungent, earnest appeal to the consciences of men-stealers." This was a damning bill, but it was true in every particular; and the evidence which Garrison adduced to establish his charges was overwhelming and irrefragable.

Nearly fifty years afterward, Elizur Wright described the baleful influence of the society upon the humanity and philanthropy of the nation. "The humanity and philanthropy," he said, "which could not otherwise be disposed of, was ingeniously seduced into an African Colonization Society, whereby all slaves who had grown seditious and troublesome to their masters could be transplanted on the pestiferous African coast. That this wretched and seemingly transparent humbug could have deluded anybody, must now seem past belief; but I must with shame confess the fact that I for one was deluded by it. And that fact would put me in doubt of my own sanity at the time if I did not know that high statesmen, presidents of colleges, able editors, and that most undoubted of firm philanthropists, Gerritt Smith, shared the same delusion. Bible and missionary societies fellowshipped that mean and scurvy device of the kidnapper, in their holy work. It was spoken of as the most glorious of Christian enterprises, had a monthly magazine devoted to itself, and taxed about every pulpit in the land for an annual sermon in its favor."

Such was the Colonization Society, and its entrenched strength in the piety and philanthropy of the country at the moment when Garrison published his "Thoughts." It did not seem possible that a single arm however powerful, was able to start its roots; but, directly upon the launching of this bolt, the roots of the Bohun Upas, as Garrison graphically designated the society, were seen to have started, and the enterprise appeared blasted as by fire. The deluded intellect and conscience of the free States saw in the fierce light, which the pamphlet of the reformer threw upon the colonization scheme how shamefully imposed upon they had been. They had believed the society "the most glorious of Christian enterprises," and, lo! it stood revealed to them a "scurvy device of the kidnapper." The effect was extraordinary. The book was seized and its contents devoured by some of the finest minds of the North. Here is an example of the interest which it excited and the converts which it made: "Last Monday evening was our Law Club meeting, and I had the great satisfaction of hearing Judge Mellen, our Chief-Justice, say he had read your 'Thoughts,' was a thorough convert to your views, and was ready to do all in his power to promote them. Mr. Longfellow [father of Henry W. Longfellow] was present also, and with equal warmth and clearness expressed himself also in favor of your views. This is getting the two first men in the State for talents and influence in benevolent effort. I have no doubt they will head the list of those who will subscribe to form here an anti-slavery society. Mr. Greenleaf [Simon] also, will cordially come in, and I need not say he is one of the first [men] in the State, for his character is known." This quotation is made from a letter of General Samuel Fessenden, of Portland, Me., to Mr. Garrison, dated December 14, 1832. Among the remarkable minds which the "Thoughts" disillusioned in respect of the character and tendency of the Colonization Society were Theodore D. Weld, Elizur Wright, and Beriah Green, N.P. Rogers, William Goodell, Joshua Leavitt, Amos A. Phelps, Lewis Tappan, and James Miller McKim.

Garrison's assertion that "the overthrow of the Colonization Society was the overthrow of slavery itself," was, from the standpoint of a student of history, an exaggerated one. We know now that the claim was not founded on fact, that while they did stand together they did not fall together. But the position was, nevertheless, the strongest possible one for the anti-slavery movement to occupy at the time. In the disposition of the pro-slavery forces on the field of the opening conflict in 1832, the colonization scheme commanded the important approaches to the citadel of the peculiar institution. It cut off the passes to public opinion, and to the religious and benevolent influences of the land. To reach these it was necessary in the first place to dislodge the society from its coign of vantage, its strategical point in the agitation. And this is precisely what "The Thoughts on African Colonization" did. It dislodged the society from its powerful place in the moral sentiment of the North. The capture of this position was like the capture of a drawbridge, and the precipitation of the assaulting column directly upon the walls of a besieged castle. Within the pamphlet was contained the whole tremendous enginery of demolition. The anti-slavery agent and lecturer thenceforth set it up wherever he spoke.

To him it was not only the catapult; it furnished the missile-like facts and arguments for breaching the walls of this pro-slavery stronghold as well.

The effect of the publication of "The Thoughts" in this country was extraordinary, but the result of their circulation in England was hardly less so. It produced there as here a revolution in public sentiment upon the subject. The philanthropy and piety of Great Britain had generally prior to the unmasking of the society, looked upon it as an instrument of Emancipation, and had accordingly given it their powerful countenance, and not a little material support. But from the moment that the pamphlet reached England a decided change in this regard became manifest. The society made fruitless attempts to break the force of the blow dealt it by Garrison in the United States. But wherever its emissaries traveled "The Thoughts" confronted and confounded them. So that Mr. Garrison was warranted in saying that "all that sophistry or misrepresentation could effect to overthrow its integrity has been attempted in vain. The work, as a whole, stands irrefutable." The attempts made to maintain its hold upon the British public were characterized by duplicity and misrepresentation beyond anything practiced in America. The work of deceiving the philanthropy of Great Britain was conducted by the emissary of the society, Elliott Cresson, a man perfectly fitted to perform his part with remarkable thoroughness and industry. Three thousand miles away from America, and practically secure from contradiction, he went about making outrageous statements as to the anti-slavery character and purpose of the colonization enterprise. As there was no one in England sufficiently acquainted with the operations and designs of the society, he was enabled to falsify facts, to conceal the real principles of the scheme with astonishing audacity and activity. He approached Wilberforce, and duped Clarkson into a belief in the anti-slavery aim of the society.

Unmasked in America, the time had come when the interests of the Abolition movement on this side of the Atlantic required that it should be stripped of its disguises on the other side also. No better instrument could be selected for this purpose than the man who had torn the mask from its features in the United States. And so in March, 1833, the Board of Managers of the New England Anti-Slavery Society notified the public of the appointment of "William Lloyd Garrison as their agent, and that he would proceed to England as soon as the necessary arrangements can be made, for the purpose of procuring funds to aid in the establishment of the proposed MANUAL LABOR SCHOOL FOR COLORED YOUTH, and of disseminating in that country the truth in relation to American slavery, and to its ally, the American Colonization Society." The managers offered in justification of their step the fact that "Elliott Cresson is now in England as an agent for the Colonization Society, and that he has procured funds to a considerable amount by representing that the object of the society is 'to assist in the emancipation of all the slaves now in the United States.' It is important that the philanthropists of that country should be undeceived, and that the real principles and designs of the Colonization Society should be there made known."

In pursuance of this mission Garrison sailed from New York, May 2, 1833. Twenty days later he landed in Liverpool. His arrival was opportune, for all England was watching the closing scene in the drama of West India Emancipation. He was an eye-witness of the crowning triumph of the English Abolitionists, viz., the breaking by Act of Parliament of the fetters of eight hundred thousand slaves. He was in time to greet his great spiritual kinsman, William Wilberforce, and to undeceive him in respect of the Colonization Society, before death claimed his body, and to follow him to his last resting-place by the side of Pitt and Fox, in Westminster Abbey.

A highly interesting incident of this visit is best told in Mr. Garrison's own words. He said:

"On arriving in London I received a polite invitation by letter from Mr. Buxton to take breakfast with him. Presenting myself at the appointed time, when my name was announced, instead of coming forward promptly to take me by the hand, he scrutinized me from head to foot, and then inquired, 'Have I the pleasure of addressing Mr. Garrison, of Boston, in the United States?' 'Yes, sir,' I replied, 'I am he; and I am here in accordance with your invitation.' Lifting up his hands he exclaimed, 'Why, my dear sir, I thought you were a black man! And I have consequently invited this company of ladies and gentlemen to be present to welcome Mr. Garrison, the black advocate of emancipation, from the United States of America.' I have often said that that is the only compliment I have ever had paid to me that I care to remember or to tell of! For Mr. Buxton had somehow or other supposed that no white American could plead for those in bondage as I had done, and therefore I must be black!"
