From this time they were subject to frequent attempts at extortion.
The last of these was made on the banks of the River Quango,
the boundary of the Portuguese possessions. A Bashinje chief, whose portrait
is given by Mr. Livingstone, made the usual demand of a man, a gun, or an ox,
otherwise they must return the way they came. While negotiations
were in progress the opportune arrival of a Portuguese sergeant
freed the travelers from their troubles. The river was crossed,
and once on Portuguese territory their difficulties were over.
At Cassange, the frontier settlement, they sold Sekeletu's ivory.
The Makololo, who had been accustomed to give two tusks for one gun,
were delighted at the prices they obtained. For one tusk
they got two muskets, three kegs of powder, large bunches of beads,
and calico and baize enough to clothe all the party.
On the 31st of May, after more than six months' travel,
Livingstone and his companions reached the Portuguese sea-port of Loanda.
The Makololo were lost in wonder when they first caught sight of the sea.
"We marched along," they said, "believing that what the ancients had told us
was true, that the world has no end; but all at once the world said to us,
I am finished, there is no more of me." Still greater was their wonder
when they beheld the large stone houses of the town.
