These movements, though the propositions of Messrs. Hale and Palfrey were voted down, were not without their effect. The Common Council of Washington appointed an acting mayor, in place of the regular mayor, who was sick. President Polk sent an intimation to the clerks of the departments, some of whom had been active in the mobs, that they had better mind their own business and stay at home. Something was said about marines from the Navy-Yard; and from that time the riotous spirit began to subside. Meanwhile, the unfortunate people who had attempted to escape in the Pearl had to pay the penalty of their love of freedom. A large number of them, as they were taken out of jail by the persons who claimed to be their owners, were handed over to the slave-traders. The following account of the departure of a portion of these victims for the southern market was given in a letter which appeared at the time in several northern newspapers: "_Washington, April_ 22, 1848. "Last evening, as I was passing the railroad dépôt, I saw a large number of colored people gathered round one of the cars, and, from manifestations of grief among some of them, I was induced to draw near and ascertain the cause of it. I found in the car towards which they were so eagerly gazing about fifty colored people, some of whom were nearly as white as myself. A majority of them were of the number who attempted to gain their liberty last week. About half of them were females, a few of whom had but a slight tinge of African blood in their veins, and were finely formed and beautiful. The men were ironed together, and the whole group looked sad and dejected. At each end of the car stood two ruffianly-looking personages, with large canes in their hands, and, if their countenances were an index of their hearts, they were the very impersonation of hardened villany itself. "In the middle of the car stood the notorious slave-dealer of Baltimore, Slatter, who, I learn, is a member of the Methodist church, 'in good and regular standing.' He had purchased the men and women around him, and was taking his departure for Georgia. While observing this old, gray-headed villain,--this dealer in the bodies and souls of men,--the chaplain of the Senate entered the car,--a Methodist brother,--and took his brother Slatter by the hand, chatted with him for some time, and seemed to view the heart-rending scene before him with as little concern as we should look upon cattle. I know not whether he came with a view to sanctify the act, and pronounce a parting blessing; but this I do know, that he justifies slavery, and denounces anti-slavery efforts as bitterly as do the most hardened slave-dealers.
