The powder into which the charcoal is crushed is thrown on to a sieve
whose bottom consists of interwoven withes of wood. The sieve is drawn
backward and forward over two wooden or iron rods placed in a triangular
position on a tub, or over a bench-frame set on the floor of the building;
the powder which falls into the tub or on to the floor is of suitable size,
but the pieces of small charcoal which remain in the sieve are emptied out
and thrown back under the stamps.

When the earth is dug up it is first exposed to the sun that it may dry.
Later on it is thrown with a shovel on to a screen—set up obliquely and
supported by poles,—made of thick, loosely woven hazel withes, and in this
way the fine earth and its small lumps pass through the holes of the screen, but
the clods and stones do not pass through, but run down to the ground. The
earth which passes through the screen is conveyed in a two-wheeled cart to
the works and there sifted. This sieve, which is not dissimilar to the one
