98 PROCESS OF MANUFACTURE. 
rial jointed to it at the opposite ends. One of these up- 
right arms is about a foot longer than the other, and its 
upper end is fitted into the bottom of a tight box or large 
bucket, containing a coarse wire strainer, which is so placed 
as to receive the juice as it flows fron the mill. The other 
arm carries a spout at one side, projecting over the side of 
the juice tank. The ends of the main tube which support 
these uprights are closed, the one next the mill permanently ; 
in the other a molasses gate, or movable plug, is fitted, so 
that the pipe which should incline slightly toward this end, 
may be completely emptied at any time. This should al- 
ways be done at the close of each day’s work. The pipe 
should be painted, the joints cemented with white-lead, and 
the upright pieces securely braced, and when it is placed in 
position, the bucket on the one arm of the tube should be 
about a foot above the level of the spout on the other.* 
The juice tank M may be made of one and a half inch 
pine plank. The joints are cemented with white-lead, and 
it is divided into two compartments by a water-tight par- 
tition. The depth of this tank should not exceed three 
feet, but its other dimensions may be extended to conform 
to any required capacity. It is most convenient, however, 
to have each half of it of such size as to contain as much 
juice as is discharged from the mill in one hour. It should 
be thoroughly painted inside and out, with red-lead or iron 
minium, and well dried before being used. 
The evaporating apparatus consists of four sections, A, 
* This is necessary to prevent the overflow of the bucket. A column 
of juice largely commingled with foam, just as it comes from the mill, is 
lighter than a column of equal height in the vertical tube at the oppo- 
site end from which the foam has separated. The equilibrium is main- 
tained only by the liquid rising to a higher level in the one arm than in 
the other. If the bucket stands but slightly higher than the discharging 
spout it will overflow.
