“Knock, knock, knock!” comes a sound against the shutters of one room every night, a passionately appealing knock that will not be stayed. Only some people can hear it, but when they do, it wrings their hearts, so importunate is it. One man I know of sitting there reading at night, used every prayer and exhortation he could think of to still that uneasy ghost--he was a priest of the Church of Rome--but it would not be stilled, and at last he--practical, middle-aged man as he was, fled away from the sound of it to some friends who lived the other side of the town, and refused ever to come back to that haunted house. Was it some unhappy woman begging and praying her master who had been her lover to intercede for her son caught in the slave revolt? Whoever it was prayed there, prayed in vain, and now sensitive souls hear the knock, knock, knock, “for God's sake have pity and help me!” Oh, most of the houses of the old slave town could tell pitiful stories. Bleby tells ghastly ones of what happened to the unfortunate slaves when the whites had recovered themselves and got the upper hand. In reading them, we must always remember that this is always the case when a handful of people holding a very much larger class by fear has been thoroughly frightened itself. There was a negro named Bailey who had hidden his master's silver for safety in a cave, and after the rebellion was over he took one of the women belonging to the estate and went to the cave to bring back to the house the property which he had hidden. He sent off the woman with a load upon her head, and remained behind to get out the rest. A company of militia came upon him thus engaged. They paid no heed to his explanations, and when the woman returned for another load he had been hanged as a man taken red-handed! But the case that Bleby dilates upon is that of a negro named Henry Williams. Now Henry Williams appears to have been a very decent, respectable man, far advanced from the wild savage who was his progenitor. He was wickedly treated, but I do not think he was exactly the martyr Bleby makes out.
