ucilage, which rather adheres to the outer envelope of the berry,
and gives the produce what is termed a "red" or "blanketty"
appearance when spread out on the barbacues. The produce is let down
by means of a small hole cut into the floor of the loft, or a
floating box, into the hopper of the pulper, and by means of a
grater forcing the fruit against the chops, the berries are
dislodged from the pulp and fall upon a sieve, which being shaken by
the machinery, lets the berries fall into the cistern, whilst the
grater catches the pulp and carries it backwards at each evolution
of the roller, around which it is encircled.
The fruit which might have passed through without being more than
half squeezed, and having only ejected one berry, is then returned
(after being shaken off by the sieve) into the hopper, to undergo
the process a second time. The pulped coffee is then permitted to
remain in the cistern for a day and a night, during which period it
undergoes a process of fermentation; it is then washed out in two or
three waters, and the whole of the mucilaginous stuff which had
risen from the berry by the fermentation is entirely washed off, and
the coffee presents a beautiful white appearance. From this the
produce is turned out to drain on a barbacue, sloped so as to throw
all the water to the centre, where a drain is placed to carry it all
off.
In an hour or so after, the coffee may be removed to the barbacues
for curing; it is there spread out thinly and exposed to the sun,
which, if shining strong, will in eight or nine hours absorb all the
water, and the coffee be fit for housing that day. I say fit for
housing, because I have repeatedly seen coffee washed out early in
the morning and put up the same evening. I cannot say I approve of
the system, though in fine weather it has been attended with
success. From the time the coffee is first exposed to the sun till
the silver skin starts, is the stage, in my opinion, during which
the produce suffers most injury. In the first instance, it should be
kept constantly turned, in order to get the water absorbed as early
as possible; and after it has been housed, the greatest precaution
should be taken to prevent its heating: and it is for this reason
that I disapprove of early housing, for if wet weather should
intervene, and the co
