SWEDENBORGS TRAVELS IN 1733.
more than ten to twelve pounds, or 1000 ducats’ worth, are
obtained annually. This, without any application of fire, is
refined gold, containing more than twenty-two carats. Nothing
is found except native gold in grains, in minute layers, and in
masses. There are some strata consisting of quartz, mixed
with reddish or yellowish slate, in which you may look for
gold, and to which the gold adheres, but it is for the most part
invisible. There is no gold ore, nor does any silver or copper
or any other noble metal adhere to it, except perhaps some
little iron or pyrites ; and yet it is contained in the pyrites
only in the granulated or native state. It has also been dis
covered in lead ; but then the lead has much gold and no
silver.
Stones from this stratum were brought from the mine to
the crushing works, of which there are three ; these works are
not alike, but arranged according to the quality, or according
to the poverty or richness, of the gold which is found in the
stone. 1. In respect to these works, where there is more
gold in the vein or stone, it is to be observed, that there are
two crushing boxes constructed in the usual way, but deep ;
the depth is an ell ; there is no sieve, but the aperture on
the side where the muddy water flows out is about three
quarters of an ell above the bottom of the box. The hammers
or stamps are weighted with large pieces of iron, and they
fall in rotation ; the water flows into a short trough which
is provided simply with two steps. 2. The most valuable part
remains at the bottom of the crushing box itself, and is not
carried out by the water ; it is now taken out and washed.
The washing plane is made in the usual way, and is about
five ells long ; there are three steps or benches, before the
ore reaches the plane itself; the upper step is small, likewise
the second, but the third is one ell nine inches long, and
one ell three inches wide. Here, on this bench, the most
valuable part remains ; this part is not covered with any cloth,
but is bare. Here the more valuable part is collected ; the
remaining parts, which are coarse, flow down the inclined
plane, the lower extremity of which is covered with cloths.
To this the coarser stony and other parts adhere ; this is
passed into a trough; and the pulverized matter which collects
