Avhich also shows tlie general typo of the vegelatioii. On the side of the railway 

 remote from the town is a large pestilential swamp which is an ideal 

 mosquito-breeding area, and serves to keep up a regular supply of these 

 insects in the town. The authorities are quite alive to the necessity of having 

 this swamp filled in, but have experienced considerable difficulty in the matter, 

 owing to the high position it holds in the local fetish or "ju-ju." It is to be 

 hoped, however, that this difficulty may be overcome in the near future. 



I visited this town on two different occasions, and as my own experiences 

 coincide exactly with those of Drs. Ingram, Morrison and Macfie, I shall content 

 myself with giving a list of the blood-sucking flies found at Baro, and an extract 

 from their report to show the nature of things as they exist at this place.

Drs. Ingram, Morrison and Macfie in reporting on an outbreak of slee23ing 

 sickuess at Baro, in which five cases were found, say : " We are of opinion that 

 the occurrence of trypanosomiasis is sporadic in Baro. There is, however, to 

 judge from the prevalence of G. palpulis at this season of the year (August), 

 no reason why it should not become epidemic. 



" An attempt was made to determine the areas in wliich the diflferent species 

 of Glossina occurred. No tsetse-flies were found along the narrow belt of land 

 between the river and the base of the clifi", which is traversed by the road 

 from Sabon Gidda to Baro. This strip of ground is kept fairly well cleared. 

 While very few were encountered on the level ground enclosed by the horse- 

 shoe-shaped plateau where Baro itself is situated, on ascending from this level 

 to the plateau, specimens of G. pulpalis and G. tacliinoides are readily found on
