bank of the Luama, this river at its confluence with the Lualaba being about 250 yards wide, with a very rapid current. On the right bank of the Luama the Mountains of Bena Twiti seem to be about ten miles distant. Passino; two more small rivers on the right bank — the Kasima and the Kalambija — we came to the rapids of M'Toka.

These rapids were formed by a whitish rock, which broke up the river into small streams. The main current was about 100 yards wide, churned into froth, and apparently not very deep. The difficulty of seeing the banks, and of following the course of the river, made it impossible to say what its exact width here was; but I should think that from the mainland on the one hand to the mainland on the other must be about two miles, though this would, to a great extent, depend on the season.
