small parasite, from one animal to another, which enters 

 the blood-stream of the animal bitten or pricked, there 

 propagates, and thus gives rise to the disease.' This theory 

 is more in harmony with modern science" (pp. 314-315).

Tsetse-fly to the north of Mount Kuldush, between JBiin 

 Feroli and Biermuddo, east of the Daghato River, a 

 tributary of the Webbi Shebeyli. 



" At night, when the camels came in, they were 

 followed by a perfect swarm of Tsetse-fly. The sting of 

 this fly, though harmless to human beings, is very painful, 

 and made me jump every time I was bitten, as if a needle 

 had been stuck half an inch into my flesh. One of my 

 ponies was badly bitten on the ' billy,' his tail not being 

 long enough to whisk the pests ofi^. The Somalis said the 

 pony would live until the next rain. We rubbed sheep's 

 fat on the ponies and the camels every day. 



"It is an extraordinary sensation, coming into a belt 

 of ' fly.' There may be but a tiny river-bed. On one side 

 of it not a fly will be encountered, but walk a dozen 

 feet and they suddenly come buzzing by one in hundreds.'
