SWEDENBORG’S TRAVELS IN 1733.
the great quantity of lime it contains , which obstructs the
pores, instead of opening them, as water generally does. This
is the reason why bathing in this water cannot be very useful.
Outside the town are iron-works, and also a paper-mill.
August 6. From Carlsbad I journeyed to the mining
towns which are situated in the neighbourhood of Saxony;
and the first I reached was Schlaggenwald, a small town, but
rich in tin, like the neighbouring towns of Schönfeld and
Lauterbach. These towns have a common interest, because
they are in one neighbourhood, and all yield tin. There are
several mines around Schlaggenwald ; and, indeed, the most
important mine is near Schlaggenwald, not far from the town,
whence diverge several veins and ramifications. Two of the
mines there are glandular, the Stockwerk, and likewise one at
Schönfeld. The ores from the Stockwerk, and from the veins
running out thence in various directions, are not treated in the
same furnaces, and by the same methods. A like difference
exists in the method of fusing the tin ore pursued at Schlaggen
wald and at Schönfeld. The reason given is that there is a
difference in the veins which are in the very nucleus or
core of the mine, and those that branch out from it. The
principal difference consists in the construction and dimensions
of the furnaces and the blast holes.
The mines are deep; at Schönfeld they reach to a depth
of from 300 to 400 ells ; in other places they are not deeper
than from 100 to 150 ells. The veins themselves in the ramifi
cations are sometimes not thicker than an ell, and sometimes
only half an ell. Some are even thinner, but, nevertheless,
the ore in them is of a rich quality. With regard to the
various kinds of veins, there is first that which is the richest
of all, and is called Zinngraupen. Of this there are two
kinds ; one a whitish, and the other a blackish, and there are
aiso intermediate colours of a dark yellowish shade ; the
veins of the yellowish colour are the heaviest, and they differ
from the others in being of an angular form, and frequently
swelling into glands (druser). The white ore occurs in large
masses, and is not figured like the black ; the white also is
scarcer than the black and dark yellowish kinds. Secondly,
there is tungsten, also very black and heavy, growing in
