In the Heart of Africa 
frequently occurred. Quite shameless demands would be quickly 
suppressed by the leader with a few forcible expressions or 
sinister motions of the hand. The keeping of the register roll 
of a caravan of 700 men strong was a highly responsible task 
for Lieutenant von Wiese, who was admirably supported in 
the work by Sergeant Czeczatka. The name of every single 
man and the amount due to him for the month had to be 
entered in the chief register. In districts where Indian or 
Arabian shops afforded an opportunity for making purchases, 
any one of them was permitted to draw a cash advance. The 
value of such advance was made to the applicant in stuffs, beads, 
or copper wire, as desired, and then entered in the register as 
wages paid. The balance of any wages due was to be paid out 
in ready money at the close of the expedition at the chief city of 
the respective districts, such as Entebbe, Bukoba, Udjidji, and 
Daressalam, and by the local authorities there, previously 
appointed to act as paymasters. 
As the men always applied for advances at the larger places 
—for instance, later on, at Kissenji on Lake Kiwu—it may be 
possible to form some idea of the immense amount of extra work 
this sort of thing entailed, and the difficulty of keeping a true 
and accurate register. 
Whilst at Rufua I received a letter from Lieutenant Weiss, in 
which he begged that instead of going to Mpororo he might be 
permitted to remain at Karagwe, south of the Kagera, and from 
there to journey across the Kagera ferry to Kanjonsa. He 
desired this in order that he might erect anew the signalling 
apparatus with which his work on the Anglo-German Boundary 
Commission had familiarised him, as the region south of Mpororo 
was to be surveyed cartographically. At the same time he asked 
that Kirschstein might be allowed to remain with him. This 
collaboration of topographer and geologist proved to be a most 
admirable arrangement, not only at that time, but later on also. 
For the first time in Africa the photo-theodolite was employed 
for topographical charts. The peculiar characteristic of this 
instrument is that it enables the dimensions of the photo-
