twenty yards wide. This fact, added to the determined opinion of the 
natives that the Kagera was an arm of the Albert Nyanza, caused me 
tothink the river worth exploring. I knew, as all know who know any- 
thing of African geography, that the Kagera could not be an effluent of 
Lake Albert, but their repeated statements to that effect caused me to 
suspect that such a great body of water could not be created by the 
drainage of Ruanda and Karagwe; that it ought to have its source 
much farther, or from some lake situate between lakes Albert and Tan- 
ganyika. 
When I explored Lake Windermere I discovered, by sounding, that it 
had an average depth of forty feet, and that it was fed and drained by 
the Kagera. On entering the Kagera I stated that it flashed on my 
mind that the Kagera was the real parent of the Victoria Nile; by 
sounding I found fifty-two feet of water in a river fifty yards wide. I 
proceeded on my voyage three days up the river, and came to another 
lake about nine miles long and a mile in width, situate on the right hand 
of the stream. At the southern end of the lake, and after working our 
way through two miles of papyrus, we came to the island of Unyamubi, 
a mile and a half in length. ee 
Ascending the highest point on the island the secret of the Ingezi or 
Kagera was revealed. Standing in the middle of the island I perceived 
it was about three miles from the coast of Karagwe and three miles 
from the coast of Kishakka, west, so that the width of the Ingezi at this 
point was about six miles, and north it stretched away broader, and be- 
yond the horizon green papyri mixed with broad gray g 
I discovered, after further exploration, 
floated over a depth of from nine to fourteen : 
papyri, in fact, covered a large portion of a long, shallow lake; that the 
mver, though apparently a mere swift-flowing body of water, oiue 
apparently within proper banks by dense, tall fields of papyri, was. a 
mere current, and that underneath the papyri it supplied a lake, varying 
from five to fourteen miles in width and about eighty geographical miles 
in length, 
Descending the Kagera again, some five miles from Unyamubi the 
boat entered a large lake on the left side, which, when explored, proved 
to be thirteen geographical miles in length by eight in breadth. 
From its extreme western side to the mainland of Karagwe east was 
fourteen miles, eight of which was clear, open water ; the other six were 
covered by floating fields of papyri, large masses or 
drift to and fro daily. By following this lake to its sou
