Suppose a poor, worn-out mother, sickly, feeble and old,—her hands worn to the bone with hard, unpaid toil,—whose nine children have been sold to the slave-trader, and whose tenth soon is to be sold, unless by her labor as washerwoman she can raise nine hundred dollars! Such are the kind of cases constantly coming to one’s knowledge,—such are the witnesses which will not let us sleep. Doubt has been expressed whether such a thing as an advertisement for a man, “_dead or alive_,” like the advertisement for George Harris, was ever published in the Southern States. The scene of the story in which that occurs is supposed to be laid a few years back, at the time when the black laws of Ohio were passed. That at this time such advertisements were common in the newspapers, there is abundant evidence. That they are less common now, is a matter of hope and gratulation. In the year 1839, Mr. Theodore D. Weld made a systematic attempt to collect and arrange the statistics of slavery. A mass of facts and statistics was gathered, which were authenticated with the most unquestionable accuracy. Some of the “one thousand witnesses,” whom he brings upon the stand, were ministers, lawyers, merchants, and men of various other callings, who were either natives of the slave states, or had been residents there for many years of their life. Many of these were slave-holders. Others of the witnesses were, or had been, slave-drivers, or officers of coasting-vessels engaged in the slave-trade. Another part of his evidence was gathered from public speeches in Congress, in the state legislatures, and elsewhere. But the majority of it was taken from recent newspapers. The papers from which these facts were copied were preserved and put on file in a public place, where they remained for some years, for the information of the curious. After Mr. Weld’s book was completed, a copy of it was sent, through the mail, to every editor from whose paper such advertisements had been taken, and to every individual of whom any facts had been narrated, with the passages which concerned them marked. It is quite possible that this may have had some influence in rendering such advertisements less common. Men of sense often go on doing a thing which is very absurd, or even inhuman, simply because it has always been done before them, and they follow general custom, without much reflection. When their attention, however, is called to it by a stranger who sees the thing from another point of view, they become immediately sensible of the impropriety of the practice, and discontinue it. The reader will, however, be pained to notice, when he comes to the legal part of the book, that even in some of the largest cities of our slave states this barbarity had not been entirely discontinued, in the year 1850.
