THOMAS DORSEY, Secretary. _Address of the Free People of Color of the Borough of Wilmington, Delaware._ We the undersigned, in conformity to the wishes of our brethren, beg leave to present to the public in a calm and unprejudiced manner, our decided and unequivocal disapprobation of the American Colonization Society, and its auxiliaries, in relation to the free people of color in the United States. Convinced as we are, that the operations of this Society have been unchristian and anti-republican in principle, and at variance with our best interests as a people, we had reason to believe that the precepts of religion, the dictates of justice and humanity, would have prevented any considerable portion of the community from lending their aid to a plan which we fear was designed to deprive us of rights that the Declaration of Independence declares are the 'unalienable rights' of all men. We were content to remain silent, believing that the justice and patriotism of a magnanimous people would prevent the annals of our native and beloved country from receiving so deep a stain. But observing the growing strength and influence of that institution, and being well aware that the generality of the public are unacquainted with our views on this important subject, we feel it a duty we owe to ourselves, our children and posterity, to enter our protest against a device so fraught with evil to us. That many sincere friends to our race are engaged in what they conceive to be a philanthropic and benevolent enterprise, we do not hesitate to admit; but that they are deceived, and are acting in a manner calculated most seriously to injure the free people of color, we are equally sensible.
