I told him, if he knew my aims as the tribes in the interior did, and as I hoped he would yet know them and me, he would be glad to stay, and see also the pictures of the magic lantern; but, as it was now getting dark, he had evidently got enough of my witchery, and began to use some charms to dispel any kindly feelings he might have found stealing round his heart.

He asked leave to go, and when his party moved off a little way, he sent for my spokesman, and told him that, "if we did not add a red jacket and a man to our gift of a few copper rings and a few pounds of meat, we must return by the way we had come." I said in reply "that we should certainly go forward next day, and if he commenced hostilities, the blame before God would be that of Sansawe;" and my man added of his own accord, "How many white men have you killed in this path ?" which might be interpreted into, "You have never killed any white man, and you will find ours more difficult to manage than you imagine."
