factory Qualification of the juice not

rally, but also elects the removal of a
large proportion of the alhuminous
matters, whose presence favors the
growth and action of forments.
II is also Of the greatest importance
that more attention be given to the
density to which the strip has been
cooked since in most cases the sirup
boiler determines by the eye and in 4
very crude way the point ut which the
strip should he drawn of.
In mnny cases the strip i. cooked to
too thick a consistency. and as a conse-
qnencs II capitalization and deposition
OF sugar take place, while. on the other
hand. il the strip IL not boiled to the
proper density. fermentation is likely to
ensne. n the preservation Of the strip
becomes a more dii.icnlt problem.
When the ordinary form of evopo.
lntor is at hand. the actual process of
evaporation can ho conducted in tn,

nary system of Qualification now in yen-I
eral use can be much improved by re.
sorting to the snlphurirg process.
In this process the Juice fresh FRONT

Juice trickles slowly down from shelf
to shelf. II meets with an ~ascendinaI
current OF sulphur fumes which arnI
produced by burning birthstone or rolll
sulphur in II roughly constructed brickI
furnace.
In this way the juice IL at once ren-l

commenced the addition of "A small
amount ct milk Of lime is frequently
to facilitate the Qualification and
renders the separation Of scums more
easy.
where the above process Of clariRca-
Ion Is employed the resulting strip is
much clearer and brighter, and at tho
anne time il can be preserved much
more readily. II it is desired to preserve
no strip for a con 5idcrable period Of
