'The;important copper- mines; o f Roras, about 68 Britilh miles-'S.-E .'
of Drontheim, vyere difcoveied m 1644. They are in the Touthetn
hope o f the chain of Dofra, in a rock of what the Germans ca]l horn-
fchiffer, or hornblende flate,- yet Bergman mentions quartz* aqd-ipjca
as ingredients; and he adds tjiat thq.gangart is ho^nberg >pr hornblende,
« of'fo fine a grain .that neither the quarts nop thp mica can be diftin-
guiftied in its texture.” * The veins are from fix inches to fix, ells .in
thicknefs ; and the ore o f a pale yellow. The mine of Stprward. is in
, a high mountain ; the rock being grey gneifs, which is followed -by a
blackilh fteatite. In general the mines, o f Roras are very prodpTive,
and a fource o f Oonfiderabie - revenue. ,Gthqr -copper anipes, -are at
Quickne and Selboe, about 5 0 miles to the, eaft of Drontheim, and at
other places.
The mines o f cobalt at Fofliim, a recent difcpvery, muft not b.e pafled
in Glencc. This metaLyields fmalt, or powder' blue, ufed in painting
pottery and porcelain, and in colouring ftarch; and the mine, is fup-
pofed to produce a clear annual revenue to ,the, crown o f about 15,000k

T h e y are chiefly fituated not far from Arindal, in. the fouthern proyince
o f Ghriftianfand; and near 'Skeen, between Arindal and Kong-fberg.f
Lead appears in the vicinity of Kongfberg; and there are alum works
near Chriftiana. Norway produces abundance o f marble, with fome
alabafter, and lapis ollaris. Rock cryftals occur o f a large fize, often
brown or yellow like thofe Of Bohemia and Piedmont, the Cairngorm
ftones of Scotland. In Iceland are found many volcanic'productions, particularly
black obfidian. The ifles of Ferroe produce agate, jafper,' and
beautiful zeolites. Jade’ and magnets are.alfo found in Norway j with
* Such indications are mentioned, as they may lead to difcpyerieq in other countries; but
Bergman’ s account is far from the accuracy 6f. modern mineralogy, and his defcriptions feem neither
to refer to hornblende nor petrofilex. From Rafpe’ sFerb er, 327, it appears that petrofilex
was conceived to be quartz and mica intimately blended,.fo as not to be diftinguilhed by the eye;
I t is equally difficult to explain Bufching’ s meaning, !. 340! when, he fays the icHief copper mines
are at Werdenfiels. Roras is in Guledal.
