length of 329 geographical miles. Its breadth varies 
from ten to forty-five miles, averaging about twenty- 
eight miles, and its superficial area covers a space of 
9240 square miles. 
On the 29 th we crossed over from our haven near 
Muzimu Island, on the east side of Ubwari, to Kioga, in 
Urundi, where we were welcomed by our old friend 
Kinoza, the chief. 
In mid-lake, I sounded, using a 3^-lb. sounding-lead 
with 1280 feet of cord, and found no bottom. I devoted 
an hour to this work, and tried a second time a mile 
nearer the Urundi coast, with the same results — no 
bottom. The strain at such a great depth on the whip- 
cord was enormous, but we met with no accident. 
On the 31st we arrived at Ujiji, after an absence of 
fifty-one days, during which time we had sailed without 
disaster or illness a distance of over 810 miles. The 
entire coast line of the Tanganika is about 930 miles.
