_15th March, 1868._--The roots of the Nyumbo or Noombo open in four or five months from the time of planting, those planted by me on the 6th February have now stalks fifteen inches long.

The root is reported to be a very wholesome food, never disagreeing with the stomach; and the raw root is an excellent remedy in obstinate vomiting and nausea; four or five tubers are often given by one root, in Marungu they attain a size of six inches in length by two in diameter.
_16th March, 1868._--We started for Mpweto's village, which is situated on the Lualaba, and in our course crossed the Lokinda, which had a hundred yards of flood water on each side of it.

The river itself is forty yards wide, with a rude bridge over it, as it flows fast away into Moero.
Next day we ascended the Rua Mountains, and reached the village of Mpweto, situated in a valley between two ridges, about one mile from the right bank of the Lualaba, where it comes through the mountains.
It then flows about two miles along the base of a mountain lying east and west before it begins to make northing: its course is reported to be very winding, this seems additional evidence that Tanganyika is not in a depression of only 1844 feet above the sea, otherwise the water of Lualaba would flow faster and make a straighter channel.

It is said to flow into the Lufira, and that into Tanganyika.
_18th March, 1868._--On reaching Mpweto's yesterday we were taken up to the house of Syde bin Habib, which is built on a ridge overhanging the chiefs village, a square building of wattle and plaster, and a mud roof to prevent it being fired by an enemy.

It is a very pretty spot among the mountains.
