u LIS llJhI many UPItClS SUOuLu nave
been discovered in working the patent;
but these have been rectifed to q great
extent, and full instructions as to the
mode of working will shortly be published.
The use of lime, except under certain cirs
cumstances, was found to be injurious to
the liquor, and Mr.. Eastes states that no
lime would have been added 10 the SCI
cond strike had he noe found the liquor
SO very acid that he thought it better to
neutralise it. Subsequent events showed
that the addition of the lime was o grave
error. However, as the result has been
favourable under disadvantageous circum-
stances, it remains for practical sugar-men
to show their skill in the manipulation Of
the agent. This will. we believe, require
a certain amount of experience, just %
with the lime process. A sugar boiler
must learn the effects which certain
quantities will produce Mr.. Eastes has
full confidence in his process, aud we
must say that the results of the last trial,
which we understand was conducted
with strict impartiality, have afforded
evidence that an agent of value bas been
discovered which may have the effect Of
increasing the annual yield Of sugar by g
Considerable percentage, The royalty for
the use of the patent has been fixed at
ten shiIings per ton of sugar produced
certainly not an exborbitaut demand, if
by this agency nothing more even were
obtained than what is shown below.
COMPARATIVE TRIALs BETWEEN EAsTEs' AND
THE OLD PROCESS.
The following are tho results OF q
series of trials at Mr.. Darts Coleridge
Mills, conducted by him under the old
process, and by Mr.. Eastes under his new
procesS:-
Crushing commenced February 14th.
Dart leading off with two strikes from the
vacuum pan of first sugars, from yellow
r4.oons Of between Ia aud 10 month";
kro WITH, tastes following with two strikes
from Yellow md Djong Djoas rAtoons Of
same age, aud about equal quantity of each
variety.
A sufficient quantity of one variety Of
cane DOT being available at this off season.
E4stes was obliged to make up his quau-
tum OF juice from a patch of Djong dong.
Owing to the canes being out Of season
and immature, the juice was very acid.
Both parties had the sauna proportion Of
green top.
Deusities from the rollers, CHARTERS,
and Subsil27s were taken not less than
three times a day, and will be found to
have been slightly it Dlrt's favour.
Both parties treated exactly the same
quantity of nice, viz. 5 $40 gallons, from
cane, wei 5hlng-Dlrt's, 40 tons I2ewt.
E,s:es, As tons 2 cwt. Thus Dart crush
ed l4ton more cane than the latter
to obtain the same quantity of juice.
This is explained by the more watery ma
ture Of the dong Doug cane crushed
by tastes.
The treatment under Eastes' process IN
no wise differs from the old method, ex-
cepting in the use Of a certain proportion
of hypochIorite OF su phur in the clarlh RS
The compounds used oy Eastes on these
trials cost in Sidney sgd. per lb.' as per
invoice submitted to us. The cost, there
fore, 100 gallons juice, is about three"
pence.
Close observation Of the appearance
and touch Of Eastes' syrups satisfies us
that no lime whatever will be required
when the density is fair and the cane in
season.
The power of this agent to coagulate
aud precipitate the albuminous or glucose
matter NAV he proved in a test lass.
