receive the fecula; the sieve is suspended on the upper part of the tub with ropeS; so as to be immersed in the water a to-and-fro movement is given to it, by which means the pulp is freed from its fecula, which falls to the bottom of the tub. After this operation, the pulp is entirely ex- hausted by merely sprinkling a small quantity of water over it. This is but a modified disposition, which is thought useful, and which does not in the least alter the mode of working. The fecula, thus separated from the pulp, sinks, after an hour's rest, to the bottom of the tub, when the depth of the tub does not exceed 60 or 70 cen- timetres, and forms a thick and solid sediment. Holes made in the sides of the tub are then opened ; that near- est the top of the sediment included. The water runs off, and the fecula is left in the bottom. If the latter is to be made in solid pieces, it is drained in the following manner. use of. It is a wooden chest, open on one side, widening m the shape of a cone toward the opening. The sides and bottom of this chest are filled with an infinity of small holes ; the exterior part is covered with a cloth of strong linen or hemp. This drainer must be placed above the tub destined to receive the water that is to be drained the fecula is then placed in the drainer, and in the course of twenty-four hours it loses all the superfluous water which it retained, and is found, it is true, in a state of humidity, bat it is sufficiently solid to be transported without being DRAINING. For this purpose, an apparatus called a drainer is made
