As a specimen of some of the incidents thus developed, is given the following fact of recent occurrence, related to the author by a lady in Boston. This lady, who was much in the habit of visiting the poor, was sent for, a month or two since, to see a mulatto woman who had just arrived at a colored boarding-house near by, and who appeared to be in much dejection of mind. A little conversation showed her to be a fugitive. Her history was as follows: She, with her brother, were, as is often the case, both the children and slaves of their master. At his death they were left to his legitimate daughter as her servants, and treated with as much consideration as very common kind of people might be expected to show to those who were entirely and in every respect at their disposal. The wife of her brother ran away to Canada; and as there was some talk of selling her and her child, in consequence of some embarrassment in the family affairs, her brother, a fine-spirited young man, determined to effect her escape, also, to a land of liberty. He concealed her for some time in the back part of an obscure dwelling in the city, till he could find an opportunity to send her off. While she was in this retreat, he was indefatigable in his attentions to her, frequently bringing her fruit and flowers, and doing everything he could to beguile the weariness of her imprisonment. At length, the steward of a vessel, whom he had obliged, offered to conceal him on board the ship, and give him a chance to escape. The noble-hearted fellow, though tempted by an offer which would enable him immediately to join his wife, to whom he was tenderly attached, preferred to give this offer to his sister, and during the absence of the captain of the vessel she and her child were brought on board and secreted. The captain, when he returned and discovered what had been done, was very angry, as the thing, if detected, would have involved him in very serious difficulties. He declared, at first, that he would send the woman up into town to jail; but, by her entreaties and those of the steward, was induced to wait till evening, and send word to her brother to come and take her back. After dark the brother came on board, and, instead of taking his sister away, began to appeal to the humanity of the captain in the most moving terms. He told his sister’s history and his own, and pleaded eloquently his desire for her liberty. The captain had determined to be obdurate, but, alas! he was only a man. Perhaps he had himself a wife and child,—perhaps he felt that, were he in the young man’s case, he would do just so for his sister. Be it as it may, he was at last overcome. He said to the young man, “I must send you away from my ship; I’ll put off a boat and see you got into it, and you must row off, and never let me see your faces again; and if, after all, you should come back and get on board, it will be your fault, and not mine.”
