Chap. XXVI. REMEDY AGAINST TSETSE. 531

 should mount the greatest number of skulls in Ins village. 



If, as has been asserted, the Portuguese ever had a cham of 

 trading stations across the country from Caconda to Tete, it must 

 have passed through these people, but the total ignorance of the 

 Zambesi flowing from north to south in the centre of the country, 

 and the want of knowledge of the astonishing falls of Victoria 

 which excite the wonder of even the natives, together with the 

 absence of any tradition of such a chain of stations, compel me 

 to believe, that they existed only on paper. This conviction is 

 strengthened by the fact that, when a late attempt was made 

 to claim the honour of crossing the continent for the Portu- 

 guese, the only proof advanced was the journey of two black 

 traders formerly mentioned, adorned with the name of " Portu- 

 guese." If a chain of stations had existed, a few hundred names 

 of the same sort might easily have been brought forward ; and 

 such is the love of barter among all the central Africans that, 

 had there existed a market for ivory, its value would have become 

 known, and even that on the graves of the chiefs, would not have 

 been safe. 



When about to leave Moyara on the 25th, he brought a root 

 which, when pounded and sprinkled over the oxen, is believed to 

 disgust the tsetse, so that it flies off without sucking the blood. 

 He promised to show me the plant or tree if I would give him 

 an ox ; but as we were travel ling, and could not afford the time 

 required for the experiment, so as not to be cheated (as I had too 

 often been by my medical friends), I deferred the investigation 

 till I returned. It is probably but an evanescent remedy, and 

 capable of rendering the cattle safe during one night only. 

 Moyara is now quite a dependant of the Makololo, and my new 

 party, not being thoroughly drilled, forced him to carry a tusk 

 for them. When I relieved liim, he poured forth a shower of 

 thanks, at being allowed to go back to sleep beneath liis skulls. 



Xext day we came to Namilanga, or " The Well of Joy." It 

 is a small well dug beneath a very large fig-tree, the shade of 

 winch renders the water delightfully cool. The temperature 

 through the day was 104° in the shade and 94° after sunset, but 

 the air was not at all oppressive. Tliis well received its name 

 from the fact, that in former times marauding parties, in returning
