RETURN TO TETTE. 
right bank, morning or evening, .shows the country swarm- 
ing with wild animals, the drought driving them all to the 
river to drink. A few miles below Chikumbula’s the party 
found a herd of hippopotami, with a white one among 
them. It was pinkish white, exactly like the color of the 
albino. The so-called white elephant is just such a pinkish 
albino as this animal. A few miles above Kariba it had 
been noticed that in two small hamlets many of the inhabi- 
tants had a similar affection of the skin. The same influ- 
ences appear to have affected men and animals. When the 
female hippopotamus has twins, she is said to kill one of 
them. The tsetse, a poisonous kind of fly, which is deadly 
to cattle, was found in various parts of this portion of 
Africa. No one knows where these insects breed ; at a 
certain season they all disappear, and as suddenly come 
back. Though the natives are generally close observers 
of nature, they could tell nothing about this insect’s 
habits. 
After three hours’ sail, on the 29th, the river was again 
narrowed, by the mountains of Mhuruma, called Karivua, 
into one channel, and rapids again appeared in the stream. 
The scenery of this pass resembled that of Kebrabasa, 
though inferior. The Karivua narrows are about thirty 
miles long. They end at the mountain Roganora. On the 
1st of November the party arrived at Zumbo, at the mouth 
of the Loangwa, and on the 23d reached Tette, having be«a 
a little over six months.
