TSETSE ON" S. BAXK OF ZAMBESI. U3 



" 1st November [1862]. — The Tsetse are verj^ troublesome 

 this morning. We did not notice them here in going, 

 nor at the last halting-place. I think there must be 

 " fly " from near the west bank of the Gwai all the way 

 to the Victoria Ealls, and beyond to the junction of the 

 Tamalukan or Lingalo's river, near Lake Ngami. Beyond 

 the Gwai to Sinamani's [on the Zambesi, about thirty 

 miles to the oast of the junction with the Gwai river] I 

 feel pretty confident there are none. There is no access 

 to the Zambesi with bullock-wagons, nor hunting on 

 horseback, nor with dogs, in these parts, unless with 

 great sacrifices, nor can I find a wagon-road, owing to the 

 broken nature of the ground — rocks, ravines, and moun- 

 tains — even where there is no ' fly.' . . . Down the Daka 

 river [according to the author's map this is otherwise 

 known as the Luisi, or Luluisi R. : it flows N.E., and 

 joins the Zambesi about 20 miles W. of the Gwai R.], too, 

 I think a road might be found as far as the river [Zambesi], 

 though a district infested by 'fly' " (Vol. II., p. 214). 



No "^y " on the south bank of the Zambesi, between the 

 junction of the Gwai JR. and Sinamani's, a little to the E. of 

 the junction of the Sebungo R., and about thirty miles E. of 

 the junction of the Gwai ; '' but this may be owing to the 

 density of the population, and the scarcity of buffaloes, 

 which are so much hunted by tlie Batonga, on account of 

 the ravages they commit in. the gardens" (Vol. TL, 

 p. 214). 



*' I think, with a little more knowledge of the country, 

 I could even find a way by which to take a wagon to the 

 Zambesi, but it would probably be impossible wholly to 

 escape the ' fly ' in doing so. These pests make their 

 appearance when and where you lea.st expect them. I 

 have not noticed any since leaving the Luluesie, but think 

 they must extend 10 or 15 miles this side of the i*iver [i.e. 

 north of the Luluesie] along the mountains" (Vol. II., 

 p. 225). 



Tsetse-fljj near the Luluesie Bivcr, Dec. 1862. — "In the 

 evening John fell in with four bufi'aloes close by, and 

 shot one of them ; but he brought the terrible news that 

 there were thousands of the ' fly ' on the one he had 

 killed. I gave orders that the cattle should go out earlv 

 to graze on the open to the south, while he returns to
