Through Ruanda to Lake Kiwu 85 
Ischangi to Kissenji, we were all united again with the exception 
of Czekanowski. 
Our union was but a short one, however, and served mainly 
to arrange our latest collections and to plan fresh excursions, 
which were calculated for a period of about a month each. 
Whilst Weiss and Kirschstein started off for surveying and 
geological purposes at the northern point of the lake and to the 
volcanic districts lying westward of Virunga, Raven, Wiese, 
Grawert, Knecht, and myself prepared for a trip to Lake Bolero. 
From there we three members of the expedition were to pay a 
visit to the eastern volcanoes and the Bugoie Forest. Mildbraed 
and Schubotz returned to Lake Kiwu, with which they were 
fascinated, and where the virgin island of Kwidschwi, and the 
biological study of the lake in general, promised them work of 
an extremely interesting nature. The following chapter from 
the pen of the zoologist will convey some idea of their impres¬ 
sions of the expanse of water and of their experiences on the 
lake.
