side of the Europeans, and the main body at the head of the 
carrier column, the rear of which was again brought up by two 
Askari and at least two Europeans. 
And then with flags flying and songs sung by the carriers, 
accompanied for a time by the rhythmical beating of sticks 
against the cases, the huge caravan set out on the march. 
Even at this stage all our Europeans were not ready for the 
march. Lieutenant Weiss and Kirschstein, the geologist, were still 
absent. They had asked for a few days’ leave of absence for 
the purpose of adjusting instruments, a matter which was better 
undertaken at Bukoba. Before any expedition sets out it is 
essential that all instruments should be subjected to a supreme 
final test as to their accuracy, as they are liable to suffer in 
transit by sea and rail. Weiss, therefore, very properly, laid 
stress upon their undergoing a final examination. Apart from 
this he utilised the opportunity to take astronomical time and date 
computations. Bukoba was excellently situated for such work, 
as its exact position had been very accurately determined by the 
trigonometrical survey of the Anglo-German boundary expedi¬ 
tion. Weiss decided, therefore, to calculate the longitudinal 
measurements by the aid of his seven chronometers. 
Dr. Czekanowski had already marched off to Marienberg. 
Early in the morning of the i8th of June we came upon a 
cave picture near Buanja, which had shortly before been dis¬ 
covered by the Mission Brothers. The walls of the cave were 
covered with strange paintings which formed an interesting record 
of primeval man’s ideas of art. 
One industrial feature of the province is the manufacture 
of material for wearing apparel out of bark. The woof is 
fabricated from the bark of the lumbue tree, and is often of 
considerable length. These stuffs, which attain an almost trans¬ 
parent fineness of texture through being beaten with wooden 
hammers, are figured with patterns, for which purpose a mixture 
of clay dissolved in water is used, and are then dried in the sun. 
At Buanja Dr. Czekanowski fell in with us again. He had 
already been very active and obtained possession of a consider-
