_7th to 21st February, 1868._--On inquiring of men who lave seen the underground houses in Rua, I find that they are very extensive, ranging along mountain sides for twenty miles, and in one part a rivulet flows inside. In some cases the doorways are level with the country adjacent: in others, ladders are used to climb up to them; inside they are said to be very large, and not the work of men, but of God. The people have plenty of fowls, and they too obtain shelter in these Troglodyte habitations. _23rd February, 1868._--I was visited by an important chief called Chape, who said that he wanted to make friends with the English. He, Chisapi, Sama, Muabo, Karembwe, are of one tribe or family, the Oanza: he did not beg anything, and promised to send me a goat.

They called out, "Kaffir, Kaffir!" and Susi, roused by this, launched forth with a stick; the others joined in the row, and the offenders were beat off, but they went and collected all their number and renewed the assault. One threw a heavy block of wood and struck Simon on the head, making him quite insensible and convulsed for some time. He has three wounds on the head, which may prove serious. This is the first outburst of Mohamadan bigotry we have met, and by those who know so little of the creed that it is questionable if one of them can repeat the formula: "La illaha illa lahu Mohamad Rasulela salla lahu, a leihi oa Salama." Simon recovered, but Gallahs are in general not strong.
