FORTIA’S TRAVELS IN SWEDEN. 389
pitch; white and blue fpar; potter’s earth. Ba/enes grufvan, another copper mine be-
longing to Ridder Hittann, is fituated a fhort Jeague from the others ;_ here you find
yellow copper ore ; ore of bifmuth in large fcales ; icaly molybdene ; tungften, or heavy
{tone; amianthus, fometimes blended with yellow copper, which gives it a beautiful
hue; quartz in flender dru/es ; potter’s earths, &c. as the copper ore is frequently mix-
ed with ore of black iron, it is rather difficult to fufe.
V¥rom Marieftadt to this place, you travel over plains in an excellent ftate of cultiva-
tion, and tolerably well peopled. This, in many refpeéts, is one of the beft diftriéts in
Sweden: all Nericiais full of forges and mines. The following are the principal places :
Quifbreu, an iron mine; Winterofa, copper and iron mine; the firft abandoned; 4x-
berg, an iron foundry ; ‘Yarboas, Nora, Linde, iron mines in the neighbourhood ; in the
two latter, which are near each other, the following varieties are found: ore of black
iron, folid, granulated, cryftallized in octaedra, difperfed in potter’s earth ; hematites of
a bluifh caft, lamillated, micacious and fparkling ; cloudy topazes in drufes; feveral va-
rieties of drufes in quartz, and calcareous {par. » Near to Nora is a fmall mine of cop-
per, in which is found folid copper ore, of {teely grain; galena; granulated ore of co-
balt, cryftallized amid the copper ore; calcareous ftone, &c. . A mile and a half diftant
from Géurebro, is Dy/ta, a large manufactory of fulphur and green vitriol. The ful-
phur is extracted from martial, pyrites, which ybound here ;_ it is diftilled in caft iron
veflels ; the refidue is lixiviated, and produces by evaporation, and cryftallization, green,
or martial vitriol: the ferruginous ochre which remains, affords a red colour, with
which the houfes are painted. At G/land/hammer are quarries of calcareous ftone, and
filver mines abandoned. At Garphyttann, two miles further, is a large allum manu-
factory ; the flate quarries are not far diltant and well deferve attention; here, black al-
lum, in flates, is found of a bituminous quality, fo that inftead of roafting it, according
to common practice, before it is lixiviated, it is ufed inftead of wood, with much fuc-
cefs, for heating cauldrons ; martial pyrites, folid, globular, and cryftallized in great va-
riety ; indurated marl, frequently of a globular fhape; calcareous {tone}; calcareous
fpar cryftallized in pyramids; lapis fuillus, brown and grey, fparkling, granulated,
{parry, rhomboidal, {triated, prifmatic, and cryftallized ; calcareous ftone, of a red and
brown colour, &c. From Garphyttann, by Sanua to He/siekulla, is a mle and a half;
here you find an iron mine, the ore confifting of black granulated iron; calcareous fpar,
white, yellow, and of a violet hue, of a pyramidal fhape, covered with hexagonal cal-
careous cryftals in drufes; rocks of granate, cryftallized granate ; and green earth of
Hefslekulla: all the {pots where thefe are to be found, are near enough to Ciurebro ;
the following are much more diftant, and thofe defirous of vifiting them mutt dedicate
feveral days to the purpofe on that account. Liu/narburg, or Nyakopperberg, contains
copper ore, formerly very rich, but at prefent very poor; it is grey, azure, and yellow;
the mine yields, alfo, galena, blend, white, violet, coloured, and green fpar; fchoerl,
fibrous, ftarry, and cryftallized in many different fhapes ; potter’s ftone, &c. Hellefors
has many mines of filver, which have been worked for a long time, but at prefent are
nearly exhaufted, yielding very little;.of minerals: galena, in fteely grains, in {mall
cubes, and micacious ; yellow copper ore, blend ; arfenical pyrites, folid, and cryftalliz-
edin needles ; martial pyrites; calcareous {par ; rock pebbles, red, brown, and black.
From Hellefors to Saxanis one mile, thence to On/bytta another. ‘This ftage is precifely
at the foot of mount Per/berg, which is full of veins of iron ore: by vifiting thefe
mines you may procure folid black iron ore, in fmall and large grains; mariial pyrites,
granulated, cryftallized in o¢taedra cubical, and in polygons in drufes ; leafy ore of bif-
muth; amianthus; potter’s {lone ; {choerl; fibrous, in {par, ftarry, cryftallized, and
prifmatic
