Avould consequently have been an act of the greatest 

 imprudence to drive the indispensable oxen and the useful 

 horses still further " [cp. 52].

[Translation.] " Nevertheless the Tsetse-f!y (Glossina 

 inorsitana, Westw.) which is so common in South and 

 North Africa does not occur in the precise territories 

 traversed by us in our journeys to Dschagga, but rather in 

 the Galla and Somali countries (we shall deal later on 

 Avith the fly and with the devastation brought about by it 

 there) ; instead of it, however, a representative exists 

 here in the shape of the Donderobo-ily, which is dangerous 

 to donkeys (see Band I., p, 249). Of species of horse- 

 flies (Tahanus), which in the North of Africa plague cattle 

 in an often incredible manner, one hears nothing here, 

 probably for the reason that the herds do not pass their 

 time in the sunny plain, but for the most part on shady 

 and cooler hills, whither these bloodthirsty flies rarely 

 stray " (Band II., pp. 83-84), 



[Dschagga is the district on the southern slope of 

 Kilima Njaro. The territories passed through between 

 Mombasa and this region, according to Map VIII. at the 

 end of the volume, were the country of the Wateita, the 

 coast region from Mombasa to Wanga, and a line from 

 the latter to Dschagga running along the northern 

 boundary of the mountain-region Usambara, Pare, and 

 Ugono. The years in which these journeys took place 

 were 1861-62.] 



Tsetse-like, cattle-destroying fly in the vicinity of Manam- 

 sunde, a town on the Juba River, not far from its mouth, 

 and just north of the equator. The Juba River enters 

 the sea a little north of Kismayu. 



[Translation.] " They [the inhabitants of Manam- 

 sunde, chiefly Wasegua] occupy themselves almost exclu- 

 sively with agriculture ; for owing to the occurrence in 

 numbers of a poisonous. Tsetse-like fly, they can keep only 

 goats and sheep, but no cattle " (Band 11., p. 303).
