468 FORTIA’S TRAVELS IN SWEDEN.
of finding green and blue porphyry, dependant on the form of the pebbles,.which are
met with in abundance. On this fpot and in the neighbourhood rock pebbles are
alfo found, red jafper, filicious breches or pouddingues, among others one of deep brown
porphyry, with knots of palered. A quantity of granite, not fo handfome as that of
the neighbourhood of Stockholm. The ftone is tran{ported on fledges during the win-
ter, and in fummer on waggons, as far as Wefteros, where it is embarked for Stock-
holm.
We fhall enter into a detail of this interefting eftablifhment. The diredtion of it on
the fpot is committed toa very capable perfon, (Mr. Hagftrocum,) for whom care fhould
be taken to be provided with letters of recommendation. There are a hundred men
employed by the day, befides a great number who work by the piece in chipping the
blocks. A labourer’s pay is from fix to nine fchillings per diem. The work effected
in the firft years of the eftablifhment can afford no juft idea of its poflible perfection,
fince the expence of the different parts of the procels is to be regarded, the mills, faws,
polifhing machines, &c. The method ufed for feparating the porphyry is the fame as is
adopted in Italy. ‘The pieces are traced with fteel pointed inftruments, which are after-
wards feparated by wedges driven by main force. At this manufaétory all forts of uten-
fils are made, tables, vafes, mortars, in one word you may have made whatever you
will by ordering it at the office eftablifhed for the purpofe at the mint at Stockholm. A
table of thirty-fix inches by eighteen, cofts 30 rix-dollars; twenty-five by feventeen
one-third, 18 rix-dollars, of which 12 are paid for workmanfhip; eighteen by twelve,
9 rix-dollars, the workmen are paid 6. A vafe of eighteen inches perfectly well turn-
ed and hollowed, cofts 40 rix-dollars ; of fourteen inches, 26 rix dollars; of twelve
inches, 25 rix-dollars; the prices are rather below thefe at prefent. Small articles are
in the fame proportion, although in general the larger coft but little more on the fpot ;
thus the latter afford a profit of at leaft 50 per cent. while the former pays no more
than 4 or 6. This eftablifhment deferves minute attention. The traveller fhould con-
trive to plan his excurfion fo as to have it take place either in fummer or the feafon
for fledges; although in the latter the fnow will prevent the fight of a number of in-
terefting objects, particularly the ftone at Mora. Soon as the thaw begins this road is
impaflible. You have to return to Fahlun by the fame road. On the way you may
vifit the copper mine of Mortamberg, in the parifh of Rattvick, which has been but re
cently opened. In it you find copper ore of a grey colour ; fometimes in azure, green,
yellow and lightifh yellow cryftals; mountain green; galena in {mall quantities ; mar-
tial pyrites; mineral pitch ; very flender druzes of quartz; white quartz; calcareous
fpar ; potter’s ftone; and amianthus in flender veins. In walking through the
parith of Rattvick you often find folid calcareous ftones filled with petrifactions, fuch as
orthocerathites, fometimes replete with mineral pitch, and calcareous fpar, frequently in
cryftals ; fhells and corals of different forts, and very rare lithnites. From Mortam-
berg you may proceed to Se/fberg, where a {mall vein of galena is worked, which is in
a flight degree argentiferous. The vein yields galena, red and yellow blend, lapis cala-
minaris, calcareous fpar, bréche of calcareous {tone, and black flate, fometimes mixed
with galena; and /umachelle, or calcareous ftone mingled with petrified fhells, with
which alfo a portion of galena is fometimes blended. From Silfberg to Ofmund/berg,
a pretty confiderable mountain, containing folid calcareous ftone ; idem, in form of
balls, impregnated with petroleum, and occafionally hollow, and lined infide with cal-
careous {par in druzes ; fluid, yet thick petroleum ; bituminous flate, frequently full of
minute petrifactions; blue clay, containing a flight portion of filver; fuller’s earth ;
and martial pyrites. ;
