PROCESS OF MANUFACTURE (CONTINUED). 
Crystallization—Treatment of the Syrup in the Crystallizing-room 
—Crystallizing Vessels—Dutrone’s Crystuailizing Box — How 
Drainage may be secured and Crystallization promoted. 
At the close of the day’s boiling, transfer the cooler to 
the erystallizing-room. Here two modes of treatment are 
to be pursued to suit the kind of product to be obtained. 
By the first mode, a fair, yellow sugar, of a quality equal to 
that of the ordinary brown sugars of commerce, is the result. 
By the second, white sugar, or any grade intervening be- 
tween it and the crude article, may be obtained. 
As a prerequisite to success by either method, the erys- 
tallizing and draining rooms should be uniformly heated to 
a temperature of not less than 80° F. (26°6° Cent.). To 
secure this, a close room is needed, opening by a door into 
another apartment instead of by an outside door. The 
crystallizing vessels should be ranged along the sides and 
a stove placed in the center. 
Crystallization and drainage should be performed in the 
same vessels, and their form should be such as to conduce 
to both these ends. 
1. Crude sugar of a good quality and large grain will 
uniformly result from well defecated syrup of the proper 
density at a temperature of 80° to 90° F. by means of 
slow crystallization and natural drainage. The vessels
