graphic plans to be ascertained in any given direction, a quality 
of great value to geologists. And thus the topographer and the 
geologist laboured loyally together; they worked out the whole 
geological projection in profile from Lake Victoria to Kiwu. 
New instructions were issued at Rufua. Dr. von Raven and 
Mildbraed were to march out with the chief caravan through 
the inhabited regions west of the Kakitumbe watercourse to the 
western end of Lake Mohasi for the purpose of studying the 
swamp flora of this lake, and to examine into the haematosis of 
the inhabitants there. Lieutenant von Wiese was sent south to 
the Kakitumbe to assist Lieutenant Weiss, the signalling expert, 
with the triangulation, and afterwards to push on to Kakome, 
at the eastern end of Lake Mohasi. Weiss and Kirschstein 
were to proceed southwards, west of the Kagera, to make a 
cartographical and geographical survey of the region lying 
between Mohasi and South Mpororo, hitherto untrodden by any 
European, and therefore not even opened up at all. Wintgens, 
Dr. Schubotz and I proposed making a general tour of inspection 
throughout this territory, and then meeting the other members of 
the party at Lake Mohasi. The reunion of forces was fixed for 
the beginning of August, after a month’s interval. 
To make amends for the loss of my European dogs, which 
had been smitten by the disastrous coastal fever, and were lying 
very sick in quarantine at Mombasa, we procured two native dogs. 
They were young, strong, well-shaped animals, yellow-brown in 
colour, with distinctive white markings and pendulous ear-laps; 
they bore a certain resemblance in form to our hunting dogs, and 
possessed an individuality of their own, the like of which I have 
seen nowhere else. We were bothered a good deal at first by 
their wild nature and their attachment to their native village, for 
they used to gnaw through the cords with which we tied them to 
the tent. In the end, however, we concluded a treaty of friend¬ 
ship with them, and once properly used to their new masters, they 
held loyally by the caravan. Only one of these animals, how¬ 
ever, native to Mombasa, but of German strain, survived the 
journey to the coast and reached Germany at the finish.
