The hollow affords a section of this part of the country; and we find that the uppermost stratum is the ferruginous conglomerate already mentioned. The matrix is rust of iron (or hydrous peroxide of iron and hematite), and in it are imbedded water-worn pebbles of sandstone and quartz. As this is the rock underlying the soil of a large part of Londa, its formation must have preceded the work of denudation by an arm of the sea, which washed away the enormous mass of matter required before the valley of Cassange could assume its present form. The strata under the conglomerate are all of red clay shale of different degrees of hardness, the most indurated being at the bottom. This red clay shale is named "keele" in Scotland, and has always been considered as an indication of gold; but the only thing we discovered was that it had given rise to a very slippery clay soil, so different from that which we had just left that Mashauana, who always prided himself on being an adept at balancing himself in the canoe on water, and so sure of foot on land that he could afford to express contempt for any one less gifted, came down in a very sudden and undignified manner, to the delight of all whom he had previously scolded for falling.
Here we met with the bamboo as thick as a man's arm, and many new trees. Others, which we had lost sight of since leaving Shinte, now reappeared; but nothing struck us more than the comparative scragginess of the trees in this hollow. Those on the high lands we had left were tall and straight; here they were stunted, and not by any means so closely planted together. The only way I could account for this was by supposing, as the trees were of different species, that the greater altitude suited the nature of those above better than the lower altitude did the other species below.
SUNDAY, APRIL 2D. We rested beside a small stream, and our hunger being now very severe, from having lived on manioc alone since leaving Ionza Panza's, we slaughtered one of our four remaining oxen. The people of this district seem to feel the craving for animal food as much as we did, for they spend much energy in digging large white larvae out of the damp soil adjacent to their streams, and use them as a relish to their vegetable diet. The Bashinje refused to sell any food for the poor old ornaments my men had now to offer. We could get neither meal nor manioc, but should have been comfortable had not the Bashinje chief Sansawe pestered us for the customary present. The native traders informed us that a display of force was often necessary before they could pass this man.
Sansawe, the chief of a portion of the Bashinje, having sent the usual formal demand for a man, an ox, or a tusk, spoke very contemptuously of the poor things we offered him instead. We told his messengers that the tusks were Sekeletu's: every thing was gone except my instruments, which could be of no use to them whatever. One of them begged some meat, and, when it was refused, said to my men, "You may as well give it, for we shall take all after we have killed you to-morrow." The more humbly we spoke, the more insolent the Bashinje became, till at last we were all feeling savage and sulky, but continued to speak as civilly as we could. They are fond of argument, and when I denied their right to demand tribute from a white man, who did not trade in slaves, an old white-headed negro put rather a posing question: "You know that God has placed chiefs among us whom we ought to support. How is it that you, who have a book that tells you about him, do not come forward at once to pay this chief tribute like every one else?" I replied by asking, "How could I know that this was a chief, who had allowed me to remain a day and a half near him without giving me any thing to eat?" This, which to the uninitiated may seem sophistry, was to the Central Africans quite a rational question, for he at once admitted that food ought to have been sent, and added that probably his chief was only making it ready for me, and that it would come soon.
