 flood. 



For the benefit of vulcanologists and others, and before 

 describing my journeys through the western and central 

 groups, I will give a descriptive account of each volcano 

 separately and some data concerning the most recent and 

 important volcanic disturbances so far as these are known. 



To take the latter first, we will begin with the three small 

 newly formed volcanoes : — 



(a) A low active cone without crater, formed by 

 explosive eruption three miles to the north of Mbusi 

 Bay (Kabino Inlet) and south-west of Namlagira volcano, 

 in May, 1904, 



(b) A smaller but higher active cone, the so-called 

 Kanamaharage volcano, with crater, formed by ex- 

 plosive eruption in an opposite direction to the last 

 named, at the eastern foot of Namlagira volcano in 

 July, 1905. 



(c) A hill-like active cone, similar to (6) ; the so- 

 called Kiverunga volcano, formed by explosive eruption 

 close to the first named {a) cone, in December, 1912. 



{d) The formation of a small lake in a valley named 



Kimbugu, to the north-east of the Sabinyo volcano, in 



June, 1920, giving off mephitic fumes. There was no 



eruption of lava. 



Then, in a class by themselves, come the eruptions of 



more or less severity of the Namlagira volcano, the most 



active cone of the entire group, which occurred between the 



years 1907 and 1910. This volcano is still (1920) remarkably 



active. 



No eruption of the second largest active crater of Nina-
