276 R. B. WOOSNAM — SEARCH FOR GLOSSINA ON THE AMALA 



The Masai reported that tsetse-fly existed upon some of these water-courses 

 •from the foot of the escarpment all the way down to the Amala river, but thai 

 on others no fly occurred. Owing to my having been able to spend so short 

 a time in the area, I can neither prove nor disprove this statement ; though I am 

 more inclined to the opinion that fly exists on all these little water-courses, but 

 that it follows some of them nearer to the escarpment than others, and that as 

 the Masai avoid as far as possible taking their cattle down towards the Amala, 

 they have only come in contact with fly on some of the streams. 



Immediately below the rapids on the Amala there is a considerable area of 

 bush, as shown on the map, which the Masai state is a fly-area, and it is conse- 

 quently interesting to note that a broad well-used cattle track passes through the 

 middle of this patch of bush. 



Between the rapids and Judd's lowest store at the bend of the river, the 

 Amala changes its character and becomes a very sluggish river, running in a 

 deep narrow channel between high banks. There is very little fall in this part 

 of the river, the country is flat and there is a great deal more bush on this 

 portion of the east bank than upon any other part I visited, and it is quite 

 possible that here both banks of the river are infested with tsetse-fly. However, 

 I camped here in October 1912, and found no Glossina, nor did Mr. T. J. 

 Anderson, who passed along this part of the river in May 1913. Throughout 

 this section of the river the west bank has far the most extensive area of bush ; 

 this is continuous with the bush along the small water-courses, already described, 

 which run into this part of the river on the west side. On the east bank there are 

 several small water-courses running into the river, but they are quite dry except 

 during the rains, and are rocky and have no bush at all on their banks, or only an 

 occasional clump a few yards in diameter. 



The whole character of the east side of this part of the river is different from 

 that of the west. The ground is more rocky and arid, more undulating, and 

 rises higher and more abruptly above the river. The grass is less luxuriant, aud 

 the country cannot be described as park-like, being extensively covered with 

 thinly scattered thorn scrub of several dark rough-barked varieties of acacia and 

 not the tall yellow-barked species. 



At the bend of the river at Judd's lower store, or a little above this, the 

 Amala again flows fairly swiftly over a rocky bed, and the banks, particularly 

 on the east side, have little or no bush upon them, only a fringe of trees along 

 the water's edge and scattered thorn scrub further from the river. How far 

 these conditions continue I cannot say, as I have never been below this bend. 

 On the west side of the river at Judd's lower store there is a considerable rocky 

 ridge, which causes the river to take the bend to the east and appears to 

 separate it at this point from the plains below the main escarpment. 



The Amala river at this point is about 75 or 80 miles in a direct line from 

 Lake Victoria, and it must flow for 150 or 200 miles before falling into the lake. 



There are large numbers of game and other animals on both sides of the 

 Amala in the portion investigated, the following species being represented : — 

 Rhinoceros, hippopotamus, giraffe, eland, waterbuck, zebra, roan antelope, wilde- 

 beest, topi, Coke's hartebeest, impala, reedbuck, bushbuck, steinbuck, oribi,
