ie; from the abandonment of the Universities Mission;
from the opposition of the Portuguese authorities; but mainly from
the distressing discovery that, encouraged by Portuguese traders,
the slave-trade was extending in the district, and the slave-traders
using his very discoveries to facilitate their infamous traffic. At
length a despatch recalling the expedition was received, July 2,
1863. Livingstone, at his own cost, had brought out a new steamer,
but she could not be put on the lake. Depressed though he was, he
explored the northern banks of Lake Nyassa on foot; then in his own
vessel, and under his own seamanship, crossed the Indian Ocean to
Bombay; and after a brief stay there, returned to Britain, reaching
London on July 23, 1864.

At home Livingstone had two objects--to expose the atrocious deeds
of the Portuguese slave-traders, and to find means of establishing a
settlement for missions and commerce somewhere near the head of the
Rovuma, or wherever a suitable locality could be found. His second
book, "The Zambesi and its Tributaries" (1865), was designed to
further these objects. He was again received with every
demonstration of honor and regard. A proposal was made to him, on
the part of the Royal Geographical Society, to return to Africa and
settle a disputed question regarding the water-shed of Central
Africa and the sources of the Nile. He said he would go only as a
missionary, but was willing to help to solve the geographical
problem.

He set out in August, 1865, _via_ Bombay and Zanzibar. On March 19,
1866, he started from the latter place, first of all trying to find
a suitable settlement, then striking westward in order to solve the
geographical problem. Through the ill-behavior of some of his
attendants a report of his death was circulated, but an expedition,
headed by Mr. E. D. Young, R. N., ascertained that the report was
false. Livingstone pressed westward amid innumerable hardships, and
in 1869 discovered Lakes Meoro and Bangweolo. All the while he was
doing what he could for the religious enlightenment of the natives.
Obliged to return for rest to Ujiji, where he found his goods
squandered, he struck westward again as far as the river Lualaba,
thinking it might possibly be the Nile, but far from certain that it
was not, what it proved afterward to be, the Congo. Returning after
severe illness once more to Ujiji, Livingstone found there, Mr. H.
M. Stanley, who had been sent to look for him by
