Excellent as was the work of these conventions of men of color, they nevertheless became the magazines from which the pro-slavery element secured dangerous ammunition with which to attack the anti-slavery movement. The white anti-slavery societies were charged with harboring a spirit of race prejudice; with inconsistency, in that while seeking freedom for the Negro by means of agitation, separate efforts were put forth by the white and black anti-slavery people of the North. And this had its due effect. Massachusetts and other States had abolition societies composed entirely of persons of Color. "_The Massachusetts General Colored Association_" organized in the early days of the agitation movement. It had among its leading men the most intelligent and public-spirited Colored citizens of Boston. James G. Barbadoes, Coffin Pitts, John E. Scarlett, the Eastons, Hosea and Joshua; Wm. C. Nell, Thomas Cole, Thomas Dalton, Frederick Brimley, Walker Lewis, and John T. Hilton were a few of "the faithful." In January, 1833, the following communication was sent to the white anti-slavery society of New England. "BOSTON, January 15, 1833. "_To the Board of Managers of the New-England Anti-Slavery Society_: "The Massachusetts General Colored Association, cordially approving the objects and principles of the New-England Anti-Slavery Society, would respectfully communicate their desire to become auxiliary thereto. They have accordingly chosen one of their members to attend the annual meeting of the Society as their delegate (Mr. JOSHUA EASTON, of North Bridgewater), and solicit his acceptance in that capacity. "THOMAS DALTON, _President_, "WILLIAM C. NELL, _Vice-President_. "JAMES G. BARBADOES, _Secretary_."
