On the passage I carefully inquired the names of several points and places, to take their bearings, and to learn the geography of the lake, but all to no purpose. The superstitious captain, and even more superstitious crew, refused to answer any questions, and earnestly forbade my talking. The idea was founded upon the fear of vitiating their _uganga_ or "church," by answering a stranger any questions whilst at sea; but they dread more especially to talk about the places of departure or arrival, lest ill luck should overtake them, and deprive them of the chance of ever reaching shore. They blamed me for throwing the remnants of my cold dinner overboard, and pointed to the bottom of the boat as the proper receptacle for refuse. Night set in with great serenity, and at 2 A.M. the following morning (8th March) when arriving amongst some islands, close on the western shore of the lake--the principal of which are Kivira, Kabizia, and Kasengé, the only ones inhabited--a watch-boat belonging to Sultan Kasanga, the reigning chief of this group, challenged us, and asked our mission. Great fraternising, story-telling, and a little pipe ensued, for every one loves tobacco; then both departed in peace and friendship: they to their former abode, a cove in a small uninhabited island which lies due south of Kivira; whilst we proceeded to a long narrow harbour in Kivira itself, the largest of all these islands. Fourteen hours were occupied in crossing the lake, of which two were spent in brawling and smoking. At 9 A.M. the islanders, receiving intelligence of our arrival, came down the hill of which this island is formed, in great numbers, and held a market; but as we were unprovided with what they wanted, little business could be done. The chief desideratum was flesh of fish or beast, next salt, then tobacco--in fact, anything but what I had brought as market money, cloth and glass beads. This day passed in rest and idleness, recruiting from our late exertions.
