done until it is dug up for manufac-
ture. When new scrub land is in
tended TO be planted, the scrub is
felled and burnt off, and the arrow
root planted in rows 5ft. apart
amongst the stumps, a hole Gin.
deep being made with mattock,
the bulb placed in it and covered
up, and then kept clear of weeds by
frequent hoeing. The time for
planting extends from the end of
August to the beginning of January.
Manufacturing The article of
commerce is manufactured from the
tubers or root stocks found adhering
to the stalks of the plant on the sur
face of the ground, sometimes up
wards sob. weight being obtained
from one plant. The season for
manufacture begins in July and
should close about the end of Octo-
Der, as by that time the root stocks
burst forth and grow vigorously;
and as the new plant grows to the
same extent the arrowroot becomes
deficient in quantity and quality.
"Mode OF Preparing the Roots for
the Mill. the tubers have
come to maturity, which is usually
nine or ten months after planting,
the stalks of the plant are cut off as
close as possible to the tubers with
a cane knife or strong reaping hook.
They are then raised with grub
bling hoe or mattock, and boys are
employed separating them, care
beng taken to knock off all the soil
adhering to them. They are then
thrown into carts or wagons to be
conveyed to the mill while quite
fresh, as the colour of the manufac-
tured article will be seriously affect
ed if the bulbs are allowed to re-
main exposed to the sun and weather
before being ground up.
"Machinery.-A Chip. engine
will be required to work an arrow
root mill capable of turning out a
ton of arrowroot per diem; other
machinery needed will be root
washer, grinding-mill, cylinder,
sleeves for separating the farina from
the pulp and fibre, and a centrifru-
gal for drying. The root washer is
q tough loft. long, 3ft. deep, and
2ft. in diameter, having a half-cir-
cular bottom through which a stream
of water is constantly running. A
spinder having pegs placed din.
apart of sufficient length to reach
within lin af the bottom and sides
of the trough, revolving in horizon
tai position, the pegs working
amongst the bulbs thrown into the
trough, thoroughly cleanses it of all
dirt, at the same time forcing the
bulbs to the end of the trough
where wooden rake is so fixed a:
to push the bulbs out of the trough
as they come to it into an elevator
which delivers them into the hopper
of the mill. The mill or grinder is
a wooden drum 2ft. Gin. on the face,
and PIT. in diameter, covered with q
sheet of galvanished iron punched,
and so placed on the drum as to
show the burr on the outside. This
drum, revolving at great speed,
and having stream of water fall
ing on it from the tanks fixed above
it, CRATES up the bulbs as they fall
into the hopper, the puly and water
passing through into sieve No. l,
this is cylinder SIT. long, having
the bottom half perforated with
holes about the size of No. Z wire
nail; the beater revolves within the
sieve, which forces the farina and
water through the perforations-the
beater being somewhat of screw
forces the pulp and fibre out of the
end. The farina and water falling
into sieve No. Pa similar one tc
No. |, with the bottom of perforated
copper, having holes little larger
than pin-the process is repeated
After passing through sieve No. z
1t runs along trough 2ft. wide ant
Gin. deep and loft. long, set to s
dead level, the farina depositing OF
the bottom of the trough as the
water runs away. The farina set,
tied at the bottom of the trough is
dug out, passed through sundry
sleeves, and washings by hand, il
tubs, and again left to subside
When sufficiently firm it is dug out
and passed through a centrifugal tc
drive all the water from it, and is
conveyed to place away flom dust
and smoke, to be dried in the sun
"Ihe mode Of drying after i
comes from the centrifugal is by
spreading it on calico laid upon mar
supial netting stretched and fastened
upon wooden frames, PIT. Gin. from
the ground; by this means the vino
dries from underneath as well a.
the sun above. 1t is not advisable
to trust to the stunt alone for drying
as sometimes succession of cloudy
or showery days will cause the ar
rowroot to 90 sour before it is dry
and thus become unsaleable. 4
drying-house should be erected cap
able of holding about three tons o
arrowroot in case of unfayourabl
, weather.
! "As the value of arrowroot de
: ponds so much upon the colour ant
quality, the greatest care should b
exercised during the whole process
