There is no trade whatever on the Zambesi below Mazaro.

All the merchandise of Senna and Tette is brought to that point in large canoes, and thence carried six miles across the country on men's heads to be reshipped on a small stream that flows into the Kwakwa, or Quillimane river, which is entirely distinct from the Zambesi.

Only on rare occasions and during the highest floods can canoes pass from the Zambesi to the Quillimane river through the narrow natural canal _Mutu_.
The natives of Maruru, or the country around Mazaro, the word Mazaro meaning the "mouth of the creek" Mutu, have a bad name among the Portuguese; they are said to be expert thieves, and the merchants sometimes suffer from their adroitness while the goods are in transit from one river to the other.

In general they are trained canoe-men, and man many of the canoes that ply thence to Senna and Tette; their pay is small, and, not trusting the traders, they must always have it before they start.

Africans being prone to assign plausible reasons for their conduct, like white men in more enlightened lands, it is possible they may be good-humouredly giving their reason for insisting on being invariably paid in advance in the words of their favourite canoe-song, "Uachingere, Uachingere Kale," "You cheated me of old;" or, "Thou art slippery slippery truly." The Landeens or Zulus are lords of the right bank of the Zambesi; and the Portuguese, by paying this fighting tribe a pretty heavy annual tribute, practically admit this.
