juice of 24S, 24Olbs. Suppose the mill,
being o good one, yields 6s per cent. ex-

with, aud the sugar result is stated at
1892 lbs, or not quite 81 per cent. oil
the weight of the canes. This is simply
miserable. Many Of the large usiaes in the
French islands return this amount to the
cultivator as his share; and they paw all
costs Of manufacture and most Of the haul
age, and get their profit out Of the eurplus
Weld. Their average return is about s
per cent. (7.92) of the wight of the canes,
and the density Of their Juice is about the
same, on the average, as that Of the Zee
landia experiment. Perhaps it would be
fairer, as the Zeelaudia molasSes was not
ro.boiled to state that their average retarn OF
1st Jet only is 81 (although have ny
doubts il the ordinary amount OF 2nd Jet
could be obtained from those casks OF mo-
lassea at Zeelandia, and suspect that they
would be- found too acid to yield crystals
enough to paw for tho conveision). 1t
must also be remembered that the French
usiae crystals are o much higher grade
than "Demcrara )" so that we find their

cess in which lime is frequently used, IA
124 per cent. more on the years average OF
their daily work, than WAS obtaIoed by q
speciQl experiment, conducted by gentle
men of known ability, OF n process IN
which lime takes no part. Let as look at
the experiment from another point OF view
We are led to believe that Mr. GiIPs pro-
cess results in less skimmlngs than tn ordl-

OF course, as this is based upon polarls-
cope readings, it is over and ABOVE the

aims al reducing waste. If we take the

more disappointing, being only SO ID, of

I 10 not mean to assert that the f0rego-
ing result can be obtained every day, nor
that it Was the result of lime-lt was the
result of good sound canes freshly cut;
and I care not what the system is, if this
factor of good sound canes freshly cut is not
omitted from the equation. good results
will follow, whether lime is added or not.
NY experience convinces me that mora
sugar is spoilt from acant Of lime Hanover
lining, and that the addition of lime does
not necessarily mean the production of
molassss. Canes mnst be sound and freshly
cut to make good sugar; but 10 process
