Benjamin Coker, a colored Methodist clergyman, forty years ago, wrote and issued, in the city of Baltimore, Maryland, a pamphlet, setting forth in glowing terms, the evils of American slavery, and the wrongs inflicted on the colored race. Rev. Daniel A. Payne, a talented clergyman, mentioned in this work, has now in his possession a copy of the pamphlet, and informs us, that the whole ground assumed by the modern abolitionists, was taken and reviewed in this pamphlet, by Daniel Coker. We may reasonably infer, that the ideas of Anti-Slavery, as taught by the friends of the black race at the present day, were borrowed from Mr. Coker; though, perhaps, policy forbade due credit to the proper source. Coker, like Russworm, became interested in the cause of African Colonization, and went to Africa; where he subsequently became an extensive coast trader, having several vessels, one of which he commanded in person, taking up his residence on the island of Sherbro, where he is said to have lived in great splendor. He died in 1845 or 1846, at an advanced age, leaving a family of sons and daughters. Henry Bibb, an eloquent speaker, for several years, was the principal traveling lecturer for the Liberty Party of Michigan. Mr. Bibb, with equal advantages, would equal many of those who fill high places in the country, and now assume superiority over him and his kindred. He fled an exile from the United States, in 1850, to Canada, to escape the terrible consequences of the Republican Fugitive Slave Law, which threatened him with a total destruction of liberty. Mr. Bibb established the "Voice of the Fugitive," a newspaper, in Sandwich, Canada West, which is managed and conducted with credit. Titus Basfield, graduated at Franklin College, New Athens, Ohio, receiving his religious instruction from the late Dr. Jonathan Walker, of that place, a physician and Covenanter clergyman. He afterwards graduated in theology at the Theological Seminary of Cannonsburg, Pennsylvania, was ordained, and traveled preaching and lecturing to the people of his peculiar faith and the public, for several years. He went to New London, Canada West, where he has charge of a Scotch congregation of religious votaries to that ancient doctrine of salvation. Mary Ann Shadd, a very intelligent young lady, peculiarly eccentric, published an excellent pamphlet, issued from the press in Wilmington, Delaware, in 1849, on the elevation of the colored people. The writer of this work, was favored with an examination of it before publication, which he then highly approved of, as an excellent introduction to a great subject, fraught with so much interest. Miss Shadd has traveled much, and now has charge of a school in Sandwich, Canada West.
