,~poaraSr DISCOVERY IN SUGAR
MAKING.

nroces, of NJ. Rousseau for the fabrication OF

60 r;tb distrust the glowing accounts that the
r,.ocb are wont to give Of their great discover
10. vet We cheerfully acknow edge that some OF
,nes. have proved Of great advantage to agri-
cultural science, aud hope that this new process
NAV on further trial, be found to possess all the

manufacture of sugar from the sorghum. Inc
chemical agents employed are cheap, have no IN

charine Juices The repeated hltrations through
animal charcoal which are now used Tor renh'hS

GRAFTON Of the syrup can be effected IN simple
apparatus.
iCeroqs plan, Is generally colorless as long as 1t
remains in the cells OF the plant, but changes
RAPIDLY on exposure to the air, because 1t con-
tans albumenoid matters and other substances,
which are colored b.own o. black by the action
Of oxygen VI. Rousseau removes the aiou9e-
mold matter 10y heating the saccharinc juice IN
a boiler with three thoIsandths o! its weight Of,
sulphate of lime plaster of paris pulverzed.
When the liquid reaches Zl2 deg.'s, all the CO.
ayula,ed matters rise 20 the surface and unite IN
a firm head, and perfectly clear juice remains,
which may be drawn of. This juice, If lett ex.
posed 20 the air, viii become as black as INK,
but il from to per cent Of It's weight of by
drafted peroxide OF iron be stirred in, IL is freed
in few seconds from all the changeable organic
matters and continues for an indefinite period
colorless. Nothing now remains to be done but
To evapOrate the water and thus obtain crystall-
zed sugar. N. Barral remarks that he has been
able to try the experiment only in the laboratory,
but he has tried j, enough to satisfy him that
the application on a large scale will be success
full In a subsequent number Of this journal he
re,firms his belief in the value Of this discovery,
and says that he has made excellent sugar by
this process. He moreover says that in few
days an experiment will be made on a large
scale, and in September next, after the gather
ing Of the beet CROP this process will be employed
in one ol the large sugar houses in France, and
several farm sugar houses viii be fitted up, which
the farmers visit, aud ascertain for themselves
all the prof, that they can derive from this dis
covery. This process has no perceptible effect
in removing the coloring matter of brown
sugar after the Juice has become Oxydzed by
the air the repeated Gltrations through animal
charcoal are then necessary TO refine the sugar
We will here mention for the benefit OF our
western friends, the remark of an experienced
sugar refiner OF this city, that reason OF the
failure to make sugar from the sorghum IN many
cases, Is that the whole stalk il ground up, top
and all, whereas the top should be cut off, and
only the main body of the stalk ground The
top often contains an acid which binders the su
gar from crystalizing, but does not prevent the
making OF good syrup.-An Ayricuituralist
