60 SWEDENBORG’S TRAVELS AND DIARIES. [Doc. 205.
under three hammers or stamps ; near the upper part of the
stamps or the head of the machine, is a triangular box resting
on a fulcrum ; this box is filled with larger and smaller pieces
of ore ; in front a stick or lever is fixed to it , and when so
much ofthe ore has been crushed under the hammers that morc
is required, a tooth inserted in the falling hammer catches the
projecting lever and gives it a shake, so that the triangular
box resting on the fulcrum is likewise shaken , and when a
sufficient quantity of ore has dropped under the hammers, the
tooth is no longer able to touch the projecting lever. This
box is capable of holding several hundred-weight of the ore.
3. The water flows in continually, and indeed on a sort of paved
surface under the triangular box ; the hammers, which are
very large and heavy, are separated from one another by a
frame-work; in each box are three hammers, and the fall be
gins from the first. 4. From three outlets the turbid water
which contains the pulverized ore is led into one trough.
5. This trough consists only of two steps or benches ; at the
foot of the trough or channel is a square reservoir ; the trough
itself is eight ells long , and then , as already remarked, the
reservoir begins. 6. The more precious powdered mass which
has been received in the first partition of the trough, is washed
in that deep and narrow washing place which is furnished
with two steps or benches , and which is called a Schlamm
bank. The finer portion is carried thence to an inclined
washing plane, which is fitted up with sods. The powder
which is carried off from the sods is taken to a third washing
plane, which is not provided with sods ; and from there it is
taken and stored away. 7. The pulverized mass which has
been retained at the bottom of the second partition of the
trough, is at once transferred to a table furnished with sods,
and thus taken up. 8. That powder which has been collected
in the reservoir is at once taken to a bare inclined plane, not
furnished with sods. The powder of the ore which has been
crushed dry, usually contains from four to twenty or even
thirty pounds of silver in the hundred-weight ; the rest from
four Loth (two ounces) to three marks. It is to be observed
in addition that outside the building there are washing tables,
with a Schlammbank, and a Schlammherd, just as inside.
