observe that the three several sorts
of layers which are found in the tree, and which, under the head of
"crushing," are recommended to be _pressed_ separately, should be
also _boiled_ separately, because the outermost layer has more
coloring matter than the next under it, which again has more than
the innermost layer. As they are boiled so will they be dried and
shipped, and each sort will have a different price in the market;
that fibre which is lightest in color bearing the preference, in
consequence of its not requiring more than _six_ hours to
bleach--whilst the darkest will, probably from its greater tenacity,
take _twelve_ to _eighteen_ hours. It is advisable to place over
each boiler the means of lifting the mass of fibre when boiled, and
suffering it to drain into the boiler before it is carried away to
be washed. This is easily effected by a chain from the roof, to
which may be hung a lever, having at that end over the boiler some
hooks attached to it, whereby the mass is lifted out of the boiler,
and the liquor thus preserved for the next boiling.

_Washing_.--It is absolutely necessary that the fibre should be well
washed after being taken out of the boiler, in order that all
extraneous matter may be separated therefrom. In choosing the site
for an establishment of this kind, care must always be taken to make
choice of a spot in the immediate neighbourhood of a large river, or
other plentiful supply of fresh clean water. The machinery necessary
for cleansing and washing the fibre may be of various descriptions;
but, perhaps a selection from one of the three following sorts will
be found to answer every purpose, viz., those used by paper
manufacturers in England, and by coffee planters and arrowroot
growers in the West Indies.

_Drying_.--The washed fibre, when hung over lines made of the
twisted fibre, or any other convenient material, will be
sufficiently dry in a few hours to be taken down, when more can be
hung up, and then several batches can be dried in a day; and it will
be necessary to have the drying ground as near the water as
possible, in order to save weight in carriage.

_Pressing_.--When the fibre is perfectly dry, it must be well
pressed, for the convenience of packing, carriage, and shipment. The
hydraulic press is the best machine that can be used
