1particles of the
stones may flow away.
The particles of medium size generally
settle in the middle part of the buddle, where they are arrested by interwoven
fir twigs. The mud which flows down with the water settles between the
twigs and the board which closes the lower end of the buddle. The tin-stone
of large size is removed separately from the buddle with a shovel; those
of medium size are also removed separately, and likewise the mud is removed
separately, for they are separately washed on the canvas strakes and on
the ordinary strake, and separately roasted and smelted. The tin-stone
which has settled in the middle part of the buddle, is also always washed
separately on the canvas strakes; but if the particles are nearly equal in size
to those which have settled in the upper part of the buddle, they are washed
with them in the ordinary strake and are roasted and smelted with them.
However, the mud is never washed with the others, either on the canvas
strakes or on the ordinary strake, but separately, and the fine tin-stone which
is obtained from it is roasted and smelted separately. The two large buddles
discharge into a cross trough, and it again empties through a launder into
a settling-pit which is outside the building.
