" During my hunting excursions along the Teoge, I 

 encountered, for the first time, that most extraordinary 

 of insects, the Tsetse {Glossina morsitans, Westw.). Among 

 the several scourges to which the traveller is subjected in 

 the South African wilderness, one of the greatest is this 

 insect ; not, it is true, as to the wayfarer's own person, 

 for he himself escapes almost unscathed, but as regards 

 the horses and cattle. 



" The Tsetse is found chiefly in the bush, or amongst 

 the reeds, but rarely in the open country. It is confined 

 to particular spots, and is never known to shift its 

 haunts. Thus, cattle may be seen grazing securely on one 

 side of a river, whilst the opposite bank swarms with the 

 insect. Should the natives, who are well acquainted with 

 localities frequented by the fly, have occasion to change 

 their cattle-posts, and are obliged to pass through tracts 

 of country where it exists, they choose, I am told, a moon- 

 light winter's night, as, during the hours of rest in the 

 cold season, it does not bite " (pp. 488-489). 



" Very lately, indeed, a party of Griquas, about twenty 

 in number, who were elephant-hunting to the north-west 

 of the Ngami, and who were provided with three waggons 

 and a large number of trek or draught oxen, lost, prior to 

 their return to the Lake, all their cattle by the bite of 

 the Tsetse. Some horses brought with them to further 

 their sport shared a similar fate.
