In the Heart of Africa 
the land, had almost become their confidential friend. Bar- 
thelemy desired to escort us to the little tribe of Batwa in the 
Bugoie virgin forest. To accomplish this we had to traverse the 
perfectly unknown territory of northern Tschingogo, which was 
only indicated on the map by dotted lines in accordance with 
general conjecture. We had to select one of the large printed 
letters on the blank expanse shown on the map to mark our 
proposed meeting place. 
As the course of the little river Mtashe appeared to run 
closely in the direction in question, we followed it up. This 
meant climbing over the western mountain margins of the 
valley. We came to a thickly populated, undulating hill 
country covered with luxuriant fields. The presence of Juwanese 
and Cambojano, the Watussi chieftains lent us by Msinga, 
inspired the inhabitants with confidence, so that we had no 
trouble in connection with the commissariat. Marching at the 
head of our caravan, their wide-ringing cries '' masimano^ mast- 
mano^ mastmanoeee resounded in the hills and valleys, and 
were immediately answered by larger or smaller troops of 
natives who willingly brought along supplies. 
Our calculations proved correct, for Mount Mhungo, where 
we pitched our camp, was, as a matter of fact, only a matter of 
two hours’ distance from our comrade. On joining him we 
marched on at once to the edge of the forest, the exploration 
of which was the main task before us. 
Anyone who is already acquainted with the flora of the 
country can, with the help of field-glasses from an elevated 
position, determine the character of the trees without any 
difficulty. We could discern the giant bamboo, the Podocarpus 
usambarensis pilger, called “umufu ” or “musi’^ by the natives, 
and the sapotad Sideroxylon Adolfi Friederici Engl.^ the 
“ mutoie ” of the natives. The podocarpus shoots up its straight, 
pillar-like stems to an immense height, particularly on the hill 
ridges, with a crown of knotted branches of picturesque beauty,
