This incident of the voyage was reported in the newspapers immediately on the arrival of the vessel at Liverpool, and introduced Mr. Douglass at once to the British public. He was treated with great attention by the Abolitionists of the United Kingdom; was invited to lecture everywhere, and rendered most valuable services to the cause of his oppressed countrymen. So deeply did he interest the philanthropists of that country that they paid seven hundred and fifty dollars to procure from his master a formal, legal certificate of manumission, so that, on his return to these United States, he would be no longer liable to be sent back into slavery. They also presented him with the sum of twenty-five hundred dollars for his own benefit, to be appropriated, if he should see fit, to the establishment of a weekly paper edited by himself, which was then his favorite project. Soon after his return in 1847 he did establish such a paper at Rochester and conducted it with ability for several years. He has since become one of the popular lecturers of our country, and every season has as many invitations as he cares to accept. He is extensively known and much respected. Many there are who wish to see him a member of Congress; and we confidently predict that, if he shall ever be sent to Washington as a Representative or a Senator, he will soon become a prominent man in either House. THE UNDERGROUND RAILROAD. Everybody has heard of the Underground Railroad. Many have read of its operations who have been puzzled to know where it was laid, who were the conductors of it, who kept the stations, and how large were the profits. As the company is dissolved, the rails taken up, the business at an end, I propose now to tell my readers about it. There have always been scattered throughout the slaveholding States individuals who have abhorred slavery, and have pitied the victims of our American despotism. These persons have known, or have taken pains to find out, others at convenient distances northward from their abodes who sympathized with them in commiserating the slaves. These sympathizers have known or heard of others of like mind still farther North, who again have had acquaintances in the free States that they knew would help the fugitive on his way to liberty. Thus, lines of friends at longer or shorter distances were formed from many parts of the South to the very borders of Canada,--not very straight lines generally, but such as the fleeing bondmen might pass over safely, if they could escape their pursuers until they had come beyond the second or third stage from their starting-point. Furnished at first with written “passes,” as from their masters, and afterwards with letters of introduction from one friend to another, we had reason to believe that a large proportion of those who, in this way, attempted to escape from slavery were successful. Twenty thousand at least found homes in Canada, and hundreds ventured to remain this side of the Lakes.
