_Buying Coffee in Arabia_

Most of the coffee in Arabia is grown in almost inaccessible mountain
valleys by native Arabs, and is transported by camel caravan to Aden or
Hodeida, where it is sold to agents of foreign importing houses. Mocha,
once the principal exporting city for coffee, was abandoned as a coffee
port early in the nineteenth century, chiefly because of the difficulty
of keeping the roadstead of the harbor free from sandbars.

In Aden there is a kind of open-air coffee "exchange" (as in Harar)
where the camel trains unload their coffee from the interior. The
European coffee merchant does not frequent it, but is represented by
native brokers, through whom all coffee business is transacted. This
native broker is an important person, and one of the most picturesque

from both buyer and seller. Certain grades of coffee are purchasable
only in Maria Theresa dollars; so a knowledge of exchange values is
essential to the broker's calling.

and makes his bid in the palm of the seller's hand by tapping his
fingers. The code is well understood by both. Its advantage lies in the
fact that a possible purchaser is enabled to make his bid in the
presence of other buyers without the latter knowing what he is offering.

_Buying Coffee in Netherlands India_

In the Dutch East Indies cultivation of _Coffea arabica_ has diminished,
the decay of the industry beginning when Brazil and Central America
became the dominant factors in the green market. Not so many years ago
coffee growing and coffee trading were virtually government monopolies.
Under government control each native family was required to keep from
six hundred to a thousand coffee trees in bearing, and to sell
two-fifths of the crop to the government. It was also compulsory to
deliver the coffee cleaned and sorted to the official godowns, and to
sell the crop at fixed prices--nine to twelve florins per picul previous
to 1874, although forty to fifty florins were offered in the open
market. Later, the p
