This continual violence, and intercourse with such bad white men as the slave-traders, kept the Africans barbarous; and made them much more barbarous than they would otherwise have been. Such a state of things made it impossible for them to improve, as they would have done if the nations called Christians had sent them spelling-books and Bibles instead of rum, teachers instead of slave-traders, and tools and machinery instead of gunpowder. Of all the African chiefs the King of Dahomey is the most powerful. He sends armed men all about the country to carry off people and sell them to Europeans and Americans. In that bad way he has grown richer than other chiefs, and more hard-hearted. Benevolent people in England have long desired to stop the ravages of the slave-trade and to teach the Africans better things. The dearth of cotton in the United States, occasioned by the Rebellion of the planters, turned the attention of English merchants in the same direction. It was accordingly agreed to send Mr. Crafts to Dahomey to open a trade, and try to convince the king that it would be more profitable to him to employ men in raising cotton than to sell them for slaves. He was well received by the King of Dahomey, who shows a disposition to be influenced by his judicious counsels. This is a great satisfaction to Mr. Crafts, desirous as he is of elevating people of his own color. Numbers who were destined to be sold into foreign Slavery are already employed in raising cotton in their native land. Wars will become less frequent; and the African tribes will gradually learn that the arts of peace are more profitable, as well as more pleasant. This will bring them into communication with a better class of white men; and I hope that, before another hundred years have passed away, there will be Christian churches all over Africa, and school-houses for the children. Mr. Crafts sold all the goods he carried out in the first vessel, and managed the business so well that he was sent out with another cargo. He is now one of the most enterprising and respected merchants in that part of the world; and his labors produce better results than mere money, for they are the means of making men wiser and better. How much would have been lost to himself and the world if he had remained a slave in Georgia, not allowed to profit by his own industry, and forbidden to improve his mind by learning to read! Mr. M. D. Conway, the son of a slaveholder in Virginia, but a very able and zealous friend of the colored people, recently visited England, and sent the following letter to Boston, where it was read with great interest by the numerous friends of William and Ellen Crafts:-- "LONDON, October 29th, 1864.
