From an article in the American Missionary, we take the following paragraph, in answer to the question, What has arrested civilization in Africa? What a sermon on the doctrine of the world's conversion. How long will it take Christian (?) nations to convert the heathen and bring in the millennium as popularly believed, when those benighted nations with whom they have intercourse, are rendered less civilized, humane, hospitable, and truthful, by such intercourse, than they were before their contact with them. Verily they are converting the heathen in the wrong direction. "Now, I ask the question—What is it that has arrested the civilization of Africa? . . . One answer, I have no doubt—and Dr. Livingstone has no doubt of it either—is that if it were not for the accursed slave trade which is now going on over the whole continent of Africa, its civilization would have advanced, and would have arrived at a much further stage. (Applause.) It is a remarkable fact that of those tribes of Africa met with by Dr. Livingstone, the most civilized, the most hospitable, the most truthful and the most humane, were not those who were in contact with the Christian nations of the world, but those who were in the remotest and most inaccessible corners of Africa, to whom and near whom the slave trade had not yet come."
