Both the Portuguese and their descendants turn their attention almost exclusively to trade in wax and ivory, and though the country would yield any amount of corn and dairy produce, the native Portuguese live chiefly on manioc, and the Europeans purchase their flour, bread, butter, and cheese from the Americans.
As the traders of Cassange were the first white men we had come to, we sold the tusks belonging to Sekeletu, which had been brought to test the difference of prices in the Makololo and white men's country.

The result was highly satisfactory to my companions, as the Portuguese give much larger prices for ivory than traders from the Cape can possibly give, who labor under the disadvantage of considerable overland expenses and ruinous restrictions.

Two muskets, three small barrels of gunpowder, and English calico and baize sufficient to clothe my whole party, with large bunches of beads, all for one tusk, were quite delightful for those who had been accustomed to give two tusks for one gun.

With another tusk we procured calico, which here is the chief currency, to pay our way down to the coast.

The remaining two were sold for money to purchase a horse for Sekeletu at Loanda.
The superiority of this new market was quite astounding to the Makololo, and they began to abuse the traders by whom they had, while in their own country, been visited, and, as they now declared, "cheated".
