SYNOPSIS OF THE PROCESS OF MANUFACTURE. 
Into one division of the double tank M, admit the juice 
from the mill through the pipe (Fig. 5) represented below, 
Fig. 5. 
and placed as indicated in Ch. XV., adopting the precau- 
tions there mentioned.* If the mill is placed upon a plat- 
form (Ch. XXV.), a straight pipe only is required 
Fill up one division of the tank to the mark, and turn 
the current of juice into the other. Add gradually to the 
former milk of lime until the red litmus paper changes 
color, stirring the juice well. Then pour in the proper 
measure of the clarifier, and stir. Meanwhile, the fire has 
been kindled in the furnace. When the water in the evap- 
orator is boiling briskly, open the gate of division A for its 
escape into B. At the same time permit the prepared 
* For the bucket upon the head of the pipe a larger vessel may be sub- 
stituted (if preferred), consisting of a tightly jointed box about 2 feet 
in length by 15 inches in width and the same in depth. ~- Two or three 
light frames, covered with coarse canvas, fitting into grooves in the 
sides of the box, divide it transversely into compartments, through 
which the juice passes successively, entering the box at one end and 
passing out into the pipe at the other. All the suspended matters in the 
liquid are thus removed, and with the advantage that the canvas strain- 
ers in the upright position are not easily clogged, and are removed with 
facility when it is necessary to clean them. The first of the series of 
strainers should be coarse, so as to arrest the grosser impurities, such as 
fragments of pith, ete., and the rest successively finer. A modification 
of this simple arrangement constitutes the celebrated /ea/ filter of Mr. 
Jos. 8. Lovering.
