586 FOURTH SEARCH AND RELIEF EXPEDITION. 
CHAPTER XLII. 
THE END OF A LONG LIFE. 
On Livingstone’s departure from TJnyanyembe, August 
24th, 1872, as has been narrated in the foregoing chapters, 
his intention was to strike in a southeasterly direction 
towards the Katanga Fountains, said to exist southwest 
of Lake Bangweolo, and having a large share, as he believed, 
in the supply of the water of the Lualaba, and consequently 
of the Nile, his firm opinion being that the Lualaba was 
none other than the great river of Egypt. 
Though nothing was heard from him directly, as he prose- 
cuted his final journey, we are able to trace his steps accu- 
rately from TJnyanyembe as far as Mpokwa in Utanda, six 
days from Tanganyika. At this village his road branches 
and runs south, through TJfipa, across the plain of the 
Rungwa. Beyond TJfipa is TJcmba, which occupies a con- 
siderable stretch of the southeastern end of the lake, as far 
as Karungu. Beyond Ivarungu, which bounds the Lake 
Liemba on the southeastern shore, begins the district of 
Liemba, which occupies the southern end of the lake, and 
much of the southeastern extremity. Passing through 
Liemba, Livingstone would arrive in Marungu. Crossing 
Marungu, ho would reach the outskirts of the great country, 
of Lunda. 
In the meantime, about the period Livingstone must 
have been toiling through the oozy marshes, bounding a 
portion of the Lake Bangweolo on the north, the fourth 
Search and Relief Expedition arrived at Zanzibar, in 
February, 1873. This party was commanded by Lieu- 
tenants Cameron and Murphy and a Dr. Dillon, and was 
sent to Africa under the auspices of the Geographical 
Society of England, and was assisted by Sir Bartle Frere, 
who was then at Zanzibar, endeavoring to obtain the first 
results which Livingstone’s energetic denunciation of the
