LIVINGSTONE’S MISSIONARY TRAVELS 
disease known as sleeping sickness is transmitted by a species of the 
tsetse-fly. 
At the end of this third journey Livingstone reached the court of 
Sebitaane, and looked on the face of the man whose name was the 
most widely known and feared throughout the region between Cape 
Colony and the Zambesi. He was a man in the prime of life, tall and 
strong, of an olive color, and “more frank in his answers than any 
other ;hief I ever met.” His career had been a checkered one. and it 
was due to his great courage and ability that he had won for himself 
the position he held as chief of the warlike Makololo. He received 
Livingstone most warmly, and it was a keen sorrow to the latter and 
a greai blow to his hopes when Sebituane died within a month of his 
arrival. 
Sebituane was succeeded by Mamochisane, his daughter, and she 
gave Livingstone and Oswell permission to go anywhere they pleased 
throughout her country. They at once marched northward to find the 
great river of which the natives had spoken, and at the end of June, 
1851, their search was rewarded at Sesheke by the discovery of the 
Zambesi in the heart of Africa. 
This was a discovery of great geographical importance, besides 
bearing directly on Livingstone’s cherished scheme of finding and 
opening routes to the oceans on either hand. Though it was then the 
dry season the stream was of evident importance. Livingstone says 
of it: “The river was at its lowest, and yet there was a breadth of 
from three hundred to six hundred yards of deep flowing water. At 
the period of its annual inundation it rises fully twenty feet in per¬ 
pendicular height, and floods fifteen or twenty miles of land adjacent 
to its banks.” 
The idea which now arose in the traveler’s mind was to follow 
this large stream from its source to its outlet on the coast. But this 
he could not do without parting from his family, and he accordingly 
resolved to send them to England, to remain there while his explora¬ 
tions continued. He accordingly took them to Cape Town, which he 
had last seen eleven years before. Their absence was to be for two 
years, but the exigencies of African travel were such that five years 
passed before he saw them again. And when they met he had sprung
