We had been eating this fruit, which, having somewhat the taste of apples, the Portuguese call Macaas, all the way from Tette; and here they were larger than usual, though immediately beyond they ceased to be found.

No mango-tree either is to be met with beyond this point, because the Portuguese traders never established themselves anywhere beyond Zumbo.

Tsetse flies are more numerous and troublesome than we have ever before found them.

They accompany us on the march, often buzzing round our heads like a swarm of bees.

They are very cunning, and when intending to bite, alight so gently that their presence is not perceived till they thrust in their lance-like proboscis.
The bite is acute, but the pain is over in a moment; it is followed by a little of the disagreeable itching of the mosquito's bite.
