We passed great numbers of hippopotami. They are very numerous in the parts of the river where they are never hunted. The males appear of a dark color, the females of yellowish brown. There is not such a complete separation of the sexes among them as among elephants. They spend most of their time in the water, lolling about in a listless, dreamy manner. When they come out of the river by night, they crop off the soft succulent grasses very neatly. When they blow, they puff up the water about three feet high. Chapter 15.

On the 27th of December we were at the confluence of the Leeba and Leeambye (lat. 14d 10' 52" S., long. 23d 35' 40" E.). Masiko, the Barotse chief, for whom we had some captives, lived nearly due east of this point. They were two little boys, a little girl, a young man, and two middle-aged women. One of these was a member of a Babimpe tribe, who knock out both upper and lower front teeth as a distinction. As we had been informed by the captives on the previous Sunday that Masiko was in the habit of seizing all orphans, and those who have no powerful friend in the tribe whose protection they can claim, and selling them for clothing to the Mambari, we thought the objection of the women to go first to his town before seeing their friends quite reasonable, and resolved to send a party of our own people to see them safely among their relatives. I told the captive young man to inform Masiko that he was very unlike his father Santuru, who had refused to sell his people to Mambari. He will probably be afraid to deliver such a message himself, but it is meant for his people, and they will circulate it pretty widely, and Masiko may yet feel a little pressure from without. We sent Mosantu, a Batoka man, and his companions, with the captives. The Barotse whom we had were unwilling to go to Masiko, since they owe him allegiance as the son of Santuru, and while they continue with the Makololo are considered rebels. The message by Mosantu was, that "I was sorry to find that Santuru had not borne a wiser son. Santuru loved to govern men, but Masiko wanted to govern wild beasts only, as he sold his people to the Mambari;" adding an explanation of the return of the
