Pulverized ore is washed in the head of this kind of a buddle; but usually
when tin-stone is washed in it, interlacing fir boughs are put into the buddle, in
the same manner as in the sluice when wet ore is crushed with stamps. The
larger tin-stone particles, which sink in the upper part of the buddle,
are washed separately in a strake; those particles which are of medium
size, and settle in the middle part, are washed separately in the same way;
and the mud mixed with minute particles of tin-stone, which has settled in
the lowest part of the buddle below the fir boughs, is washed separately on
the canvas strakes.

The divided buddle differs from the last one by having several
cross
boards, which, being placed inside it, divide it off like steps; if the buddle
is twelve feet long, four of them are placed within; if nine feet long, three.
The nearer each one is to the head, the greater is its height; the further from
the head, the lower it is; and so when the highest is a foot and a palm high,
