Rlancn6, Onion, anu some Vi tuc Sm"iioE OeAuos'
have purchased their machinery in Belgium, or
from other establishments in France. | have
also seen some English machinery, particularly
mills, in some of the Usines.
DESCRIPTION OF THE WORK.
Though not the most imposing, as it has evil
IDENTIFY been constructed in piecemeal, com
menoed without any fixed plan, or even
knowledge of what was required, and continued,
augmented, and finished as necessity pointed
out what was wanted, still for all this it is now
q most convenient Usine unsightly, but COM
modious. L%areinty, in good yielding weather,
makes eighty hogsheads Of sugar a day. it has
two mills, the smaller one from Gail, the larger
from an English house, they both do good work,
but neither equal to that of Pointe Simon. The
large mill is worked night and day, the small
one but seldom works at night; they ground,
in 1871, forty-six thousand eight hundred and
sixty-one tons of cane; forty-six persons are
employed to throw canes from the Wagons to
the cane carrier, the construction of the iron
part of these. " the links" which bind together
the endless boarding, is the best | have ever
seen. Behind each mill are two persons to
throw back any piece of megass that nay not
have been thoroughly squeezed, the extraction
IS about 90 per cent. on weight of canes
ground; the megass, as it leaves the mill,
is carried up to a second story by a megass
carrier attached to, and worked by the mill
this throws it on the flooring from whence it is
pushed over and shot down to the furnace
mouth of each boiler. These are such as are
used for locomotive engines, and in all the
Uslnes appeared to be about the same size,
twenty-seven feet over all; furnace about
seven feet, boiler and smoke box about twenty
feet; the boiler, about four feet diameter, con.
tanning generally eighty tubes of % inches
diameter. The boilers have no masonry about
them, but stand on solid foundations; the Chin
neys are placed on top of smoke-box, and, in
the case of Lareinty, each three chimneys
converge to one of very large dimensions, and
Of sheet iron the other USines have the CHM
neys of each boiler separate. Monsieur Quen-
nesson, whom | consider a great authority on
such matters, tells me be intends to carry out
this system of chimney in uH the Usines he
is connected with. There is but a trifing
difference in the size of the four furnace Chin
neys of Lareinty; the largest is 529 inches
diameter by III feet high.
Combustion is very rapid; the green megass
from the platform above, is at once supplied
by a shoot, delivering it on a kind of platform
In front of each boiler furnace, the stoker
adding occasionally a little coal, as the doors
of the furnace cannot be shut owing to the
sides of the table, it is kept shut by megass.
Steam is worked at high pressure, which, from
the construction of the boilers, can be done
with safety, and serves to economize fuel; q
tally board is placed near the stokers, and
the Superintendent of this department keeps
an exact account of the daily weight of Goals
consumed in each boiler; each basket of coal
is supposed to weigh twenty-five kilogrammes,
and each boiler consumes about t~hirty-six
baskets in ten hours,=792 kilogrammes, or
l646lbs. avoirdupois. With the help of this
coal the megass burns readily and emits great
heat; at Lareinty there are eleven boilers
kept at work by twenty-five fremen, forming
two separate gangs of eleven each they stoke
six hours alternately at night they each stop
fire in rotation commencing at boiler No. /
clearing out furnace, boiler, tubes, ash pit, and
snoke-box. AS No. l relights his fire, No.
2 stops and cleans up, and thus till the eleven
are cleansed this is never omitted.
The cane juice, on leaving the mill, passes
through an iron trough or canal, having three
s%trainers. and entering a Montejus to be car
ried to the steam CHARTERS in the upper story of
the building there are nine of these hemis-
pherical double bottomed, containing each $50
gallons. From these the clarified juice descends
to the subsiders. Of these there are six. All
the liquor | saw was mostly over tempered, and
it struck me more care might be taken in this
department generally. They appear to trust
