_Method of manufacturing black tea_.--The young and fresh leaves on
being picked (they only being used, the old ones being too hard, and
therefore unfit to curl), are carried to the manufactory, and spread
out in a large airy room to cool, and are there kept during the
night, being occasionally turned with the hand if brought in in the
afternoon; or, if brought in during the morning, they are allowed to
lie until noon. Early in the morning the manufacturers visit the
airing room, and pack up the leaves in baskets and remove them to
the manufacturing room. Each manufacturer takes a basketful, and
commences to beat them between the palms of his hands with a lateral
motion, in order to soften and make them more pliable for working,
and thus prevent them, when rolled, from breaking. This beating
process continues for about an hour, and it may either consist of
one or two processes; the Chinese sometimes finish the beating
process at once; at others, they allow the leaves, after being beat
for half an hour, to remain a time and then resume it. They now go
to breakfast, and in one hour and a half the leaves are ready for
the pan. The pans being heated by wood placed in the oven, so as to
feel hot to the hands, are filled to about two-thirds, or about
three seers of leaves are thrown in at a time--the quantity which a
manufacturer is capable of lifting with both hands. With the hands
the leaves are kept moving with a rotatory motion in the pan, and
when they become very hot, the motion is kept up with a pair of
forked sticks. This process is continued for three or four minutes,
depending on the heat of the pan, or until the leaves feel hot and
soft. They are then, with one sweep of a bamboo brush, swept into a
basket, and thrown on to the rolling-table, which is covered with a
coarse mat made of bamboo. Each manufacturer then takes as much as
he can hold in both hands, and forms a ball and commences to roll it
with all his might with a semicircular motion, which causes a
greenish yellow juice to exude. This process is continued for three
or four minutes, the balls being occasionally undone and made up
again. The balls are then handed to another party at the extremity
of the table, to undo them and spread the leaves out thinly on flat
baskets and expose them to the sun, if there is any; if not they are
kept in the manufactory. After all the leaves have gone through this
process, the first baskets are brought back, and the leaves again
transferred to the pan, worked up in a similar manner for the same
length of time, re-transferred to the table, and again rolled. This
being done, the leaves are again spread out on large flat baskets to
cool. On being cooled the leaves are collected together and thinly
spread out on flat wicker-worked sieve-baskets, which are placed in
