Finally, brethren, we are not strangers; neither do we come under the alien law. Our constitution does not call upon us to become naturalized; we are already American citizens; our fathers were among the first that peopled this country; their sweat and their tears have been the means, in a measure, of raising our country to its present standing. Many of them fought, and bled, and died for the gaining of her liberties; and shall we forsake their tombs, and flee to an unknown land? No! let us remain over them and weep, until the day arrive when Ethiopia shall stretch forth her hands to God. We were born and nurtured in this Christian land; and are surrounded by christians, whose sacred creed is, to do unto all men as ye would they should do unto you--to love our neighbors as ourselves; and which expressly declares, if we have respect to persons, we commit sin. Let us, brethren, invoke the christian's God, in our behalf, to do away the prejudices of our brethren, that they may adopt the solemn truths of the gospel, and acknowledge that God is no respecter of persons--that he has made of one blood all the nations that dwell on the face of the earth--that they may no longer bring their reasonings in contact with the omniscience of Deity; and insinuate to the public, that our intellect and faculties are measurably inferior to those of our fairer brethren. Because adversity has thrown a veil over us, and we, whom God has created to worship, admire and adore his divine attributes, shall we be held in a state of wretchedness and degradation, with monkeys, baboons, slaves, and cattle, because we possess a darker hue? We feel it our duty ever to remain true to the constitution of our country, and to protect it, as we have always done, from foreign aggressions. Although more than three hundred thousand of us are virtually deprived of the rights and immunities of citizens, and more than two millions held in abject slavery, yet we know that God is just, and ever true to his purpose. Before him the whole world stands in awe, and at his command nations must obey. HE who has lately pleaded the Indian's cause in our land, and who has brought about many signal events, to the astonishment of our generation, we believe is in the whirlwind, and will soon bring about the time when the sable sons of America will join with their fairer brethren, and re-echo liberty and equal rights in all parts of Columbia's soil. We pray the Lord to hasten the day, when prejudice, inferiority, degradation and oppression shall be done away, and the kingdoms of this world become the kingdoms of our God and his Christ. Signed in behalf of a public meeting in Brooklyn. H. C. THOMPSON, Chairman. GEORGE HOGARTH, Secretary. A VOICE FROM HARTFORD. HARTFORD, Ct., July 14, 1831.
