Extensive coffee plantations were found to exist on the sides of the several lofty mountains that compose this district.

They were not planted by the Portuguese.

The Jesuit and other missionaries are known to have brought some of the fine old Mocha seed, and these have propagated themselves far and wide; hence the excellence of the Angola coffee.

Some have asserted that, as new plantations were constantly discovered even during the period of our visit, the coffee-tree was indigenous; but the fact that pine-apples, bananas, yams, orange-trees, custard apple-trees, pitangas, guavas, and other South American trees, were found by me in the same localities with the recently-discovered coffee, would seem to indicate that all foreign trees must have been introduced by the same agency.

It is known that the Jesuits also introduced many other trees for the sake of their timber alone.
