RiIIieux's Sugar Apparatus.
New ORLEANS, Feb'y l. 1s4s.

,
SIR-As the subject of the enclosed is o
such great interest TO our State, do no
deem 1t necessary TO offer any apology il
presenting il to you for your consideration
l applied to Mr.. Rillieux, as the persol
| best qualified, by his known talents as Al
| engineer, and experience in sugar making
for information on the subject, and | fee
assured that his letter and tables will b,
! found well worthy of the careful attention o
our enterprising planters. have other com
muuicatiOns on this subject, but as his letter.
and tables are so full and complete, thinl
it only necessary to refer to the comments o
Mr.. W. Elihu Thompson, engineer, who tool
/ off the last two crops of Messrs. Armant anC
Brothers, with "24 600 pound \. Rillieu1
four-pan Apparatus.n He says that they
have run it at the rate of $1,000 pounds in
twenty-four hours, with perfect ease, and
that on trial made in presence of Mr.. Val
eour Aime's engineer, and others, on the 5th
of January last, they proved by actual meas
urement, that the consumption Of wood was
but one-half cord per 1000 pounds of sugar
Mr.. c. G. Allen, the engineer who took of
the last two crops for Mr.. Camille Zeringue,
with 1900 pound n. Rillieux three-pan
Apparatus" says, that they made 81 200 lbs.
first sugars, and $500 lbs. second sugars in
forty-eight hours. Mr.. Lesseps' "12, ,OOO
pound \. Rillieux three-pan Apparatus" has
made 5000 lbs. first sugars, and 60O0 lbs.
molasses sugars in twenty-four hours. And
similar results have been produced with 9th
er of these Apparatus.
Professor MeCulloh-who was appointed
by Act OF Congress, Sd March, I54S, to inves-
tigate the different methods of sugar making
in the West India Islands and in this State
in his report to Congress on the 1st of March,
IS47, remarks on the process of n. Rillieux :
1.-The use of the latent heat of the vapor
from one portion of syrup, for the evapora-
tion of another portion, hiss been accomplish
ed far more perfectly and fully by an Appar-
atus invented by y. RillieuX, of New Orleans.
than by the system of N. Derosne. This
Apparatus has also the merit of being sim
pie, and therefore, the more easily construct
ed or repaired; so that it is less liable to de-
rangement, and less expensive Ii may now
be considered as fully tested, and as perfectly
successful, so that it may be adopted with
entire security and certainty OF results -
He also adds: "When in Louisiana, visited
the plantation of Messrs. Benjamin Il Pack
wood, at their invitation, and carefully ex-
alined the Apparatus of NJ. Rillieux, con-
struciSd for them by Messrs. Merrick and
Towne. From what l learn from these in
telligeut gentlemen, as well as what then
saw, can bear witness to the entire success
of the system" he adds also: " Liquoring
may be performed in pneumatic pans OF tigers,
but there is some difficulty experienced in
the operation, in consequence of obstruc-
ton, If it be urged very rapidly. When /
was in Louisiana, Mserrs. Benjamin & Pack
wood had tried unsuccessfully, to overcome
the above mentioned difficulty of obsfruc-
ton; they have since succeeded entirely,
and their present crop has been msnufac-
tured, with Rillieux's Apparatus and pneu-
matte pans, into liqnored sugar of perfect
quality. Aspecimen of this sugar, presented
to me BY Messrs. Merriek and Towne. has
been analysed by me, and found to be eheDti-
odlly pure. Its crystalline grain and snowy
whiteness are also equal to those of the best
double-refined sugar of our northern refiners.
To Aessrs. Benjamin and PaekwOod must
therefore be awarded the merit of having
first made, directly from vegetable juice,
sugar Of absolute chemical purity, combined
with perfection Of crystal and color This is
indeed q proud triumph in the progress of
the sugar industry. In the whole range of
the chemical arts, am not aware of another
instance il, which a perfect result is in like
manner obtained Immediately
II there is any error in the statement of
the results Of the Apparatus, of either of the
methods, shall be most happy to be inform
ed of it by the planter, and 10 have it cor
rected. As the factor for several Of the
planters having the IN. Rillieux Apparatus"
am enabled to verify the statement of n.
Rillieux, as to the prices of the sugars, and
the quantity.
The terms for the Apparatus are SO easy,
that the most cautious planter need not hes
itate in getting it. 1t is important that carly
application be made BY those who want it
for the next crop, to insure the execution of
their order in time.
Your most obd't seTy't,
W. E. THoMPsos,
Agent for Merrick & ToKne, Philadelphia.
