This looks almost too good to be true still,
here We have the practical details fairly given,
and it will be for our practical planters to scruu-
uize and pick holes in them.
It is not the frst time that the use Of scientific
instruments has been the means Of revealing un-
suspected riches. and enabling the manufacturer
and chemist TO turn the raw material passing
through their hands 10 very much greater advant-
age than ever before and we doubt if Mr.. Rus
sell would have ever found out practical way OF
extracting this extra quantity Of sugar out OF the
sugareane had it not been for the aid derived by
him from the use Of that wonderfully delicate and
accurate Instrument the polariseoPe. Others
have labored in the same field, aha have made
valuable discoveries, but we question il any of
them were possessed Of the varied abilities and
command Of means and opportunities which Mr..
Russell has brought TO bear on the whole sub
iect and We congratulate our planter friends on
the fact that Mr.. Risen the eminent practical en-
gineer. who has worked with Mr. Russell 10 this
and other important improvements 10 machinery
for the manufacture OF our staple product, goes to
England by the next mail to superintend the
making Of the necessary machinery. 50 that We
may hope to see, within few months, Mr.. Rus
sells new process in full operation. and giving
even larger profits than are foreshadoEed 10 the
foregoing remarks.
There Is one way Of looking at the question
which seems to leave no room for doubt, aud that
is the fact that juice richer than the beet-sugar
manufacturer has TO deal with is at once gained
BY he process in other words, our planters will
have so per cent Of juice added to their product
richer IN sscchsrine and much easier to deal with
than the crude juice OF the beet. Mr.. Russell ex-
poets that the reduced canejuiee will be suscep,i
bic of much finer clari6catio0, and that the juice
viii be purified and ready to boil in vaeuo at
much lower gravity than the juice obtained by the
appliances at present 10 use. 1t is well known
that the beet-sugar boilers have TO keep their
juice at or below 5 : Beaume. otherwise their de-
location is faulty and We can readily understand
that the sane will hold good with cane,juce in
fact, We have often seen buckets Of clean water
thrown into the iaehes when the syrup had ar
rived at 20 Beaume. to facilitate the separation
Of Impurities. We understand that this is often
done with rich juice in Barbados.
Startling, astonishing even, as are the results
thus indicated. we have the best authority for
stating that they are below, rather than in excess
Of what has been positively established by infalli-
bic experiment.
The calculations with respect to the quantity
Of coal required for evaporation are based upon
he result Of Mr.. Sskerls recent experiments at
Beiair with the Fletcher Broekelhurst steam-pan;
Dat Mr.. Russell confidently expects to be able to
axe out still more sugar with less water when
lis sieaming arrangements are complete. In
act. the arrangements are such that while the
nil is making two revolutions the megass will be
lesrly pArboiled, and oil the water and steam
lsed IN maeeration will be trapped from the diff
erent vessels and machines throughout the
sorks. In the foregoing statement the quantity
Il eanejuiee per hogshead, and the loss in work.
ng, have been purpOsely pat very high, in order
o avoid any possibility Of misleading distant
eaders. As 9 matter Of fact, Mr.. Russell has
made a hogshead Of sugar from 1900 GALLONS Of |
lice. and has worked TO within per cent Of |
'olariseopic Indications When such results can |
e achieved il the case Of such powerful mill, |
nd with make-shift arrangements, what may not 1
