SPIRIT OF POTATOES.

E, it hangs by the extremity C, and causes the double trap to open, and thus to let the boiled potatoes fall out. The tube f (fig. 14) is destined to introduce the steam into the tub A; its internal orifice is protected by an inclined plane c, full of holes. This keeps the potatoes from stopping the tube F, and from thus becoming an obstacle to the free entrance of the steam ; it is also use- ful, the same as the plane H, to prevent the boiled pota- toes from being left in the corners of the tub. By means of this apparatus and of the boiler just described, 900 kilogrammes of potatoes may be boiled in one hour; this will require 14 kilogrammes of coals. It is necessary, as a matter of economy, to lute the various parts of this ap- paratus through the joints of which steam might be lost. This is done by means of clay mixed with some other substance. The most convenient place that can be given to the tub is above the hopper of the reducing machine, which will shortly be spoken of.
