The general process Of sugar refini
is simple and easy to gather, but in t
parts that do not show most delica
manipulation is required
A Boston Advertiser reporter recent
explored the mysteries of turning
brown, sandy, raw sugar in the stoI
house into the barfelfuls Of whit
shining sweetness that the coopers ~
heading up on the lower floor. y
The processes of sugar refining "A
simply these: The sugar is melted q
certain degree OF density, and at
proper degree a. heat is strained, Just

Then it is filtered through boneblack

is boiled downlnto sugar again.
The sugar is dumped into asgreat v,
melted in hot water and stirred up wi
a constantly moving stirrer. A stray

barrels and bags are washed and ste
to get all the sugar out, and ey6
sorapings from the floor are saved
melted sugar now goes toto the hi

established.

gram and no other that will do for filte
ing sugar. The boneblack is heated r,
hot in enclosed chambers, allowed
partly cool, away from the air, then it
slowly passed through the rooms, coo
ing, till it reaches the "char filters
When these are charged, the sugar

clear as water Toward the last of Il
tiltering the ''char" loses its power, al

are made.
Next the sugar is boiled T. is pump,
into the boilers, vacuum pans, which

Then the sirup bubbles and boils, tilll

size of the grain by careful boiling, al
shut off the steam when the right m

Next follow the centr:fugals, whe
the mixture becomes sugar. Down fro

the sugar falls, fifty pounds at time, in
a hollow cylinder surrounded by
pocket. The wall Of the cylinder ia

times minute, and the moist suq
flies up the side in its hurry to get aws
from the center OF revolution. III
sirup spurts out through the tiny hol
in the sieve, and the grained sugar alo
remains. The srup all extracted, /
sugar is washed, still revolving, with
hose.
Drying is done by passing warm Gu
rent OF air through the sugar as it sill
