EXPERIENCE IN SORGHUM AND IMPHEE.

gearing, and always with a graduated, self-regulating pressure 
upon one of the rollers, and with sufficient power to remove all 
the juice ; it should also be free from the constant leakage and 
liability to clog, which characterizes some now in use. 
We think that mills of greater strength than those in com¬ 
mon use, will be demanded soon as the business becomes more 
settled, especially for working cane partly frozen. 
The juice should pass immediately from the mill to the evap¬ 
orator, and be filtered in the passage. 
We have used a coarse woolen bag, of about two pail capaci¬ 
ty, attached to the receiving tank, with an alternate to take its 
place while shaking out the deposit, which will clog it every 
hour. Some recommend a gravel filter, which we have never 
tried, but something is necessary; even the receiving tub filled 
with straw, will do temporarily. 
The juice should not be exposed to the air over twenty min¬ 
utes before heating to the boiling point ; and now comes the 
climax of all the process, the reduction to syrup, and without 
that simple combination of furnace, boiler, and cleanser, in the 
adjustable rocking machine called “ Cook’s Evaporator/’ or 
some equivalent, we could not have patience to engage in the 
business at all. But this is so simple, economical , portable and 
effective , that it is a pleasure to run it, and instead of its being 
the burning, sooty, dipping, daubing operation of the old way, 
the operation is cleanly, pleasantly and quickly performed, as 
your committee do report. 
We have operated this evaporator in different portions of the 
State, and it has given surprising satisfaction where exhibited. 
Its construction is upon a new principle, which secures the con¬ 
stant flow of the juice, from the time it enters until it passes 
off syrup. It also retains the scum and feculent matter at the 
ends of the several channels, from which it can be removed 
every half hour, and performs the cleansing operation better 
than by introducing alkalies and foreign ingredients. Our 
limits will not admit of a minute statement of our experience 
and observation on this new branch of productive industry;
