NATURAL HISTORY of NORWAY. 20? 



Hot eafily feparated from its fediment, fo as to be brought to a 

 proper tranfparency, and on this account is fo much the cheaper*. 

 However, this fediment makes a fine brown dye, like the W ell- Abrown .^ e 

 known Englifh oker, and fome fpots of this kind are found in 

 Moraffes ; this, when carefully taken up, fo as to be clear of 

 fand, is found fit for painters. I myfelf accidentally alighted upon 

 fuch a kind of brown oker in the parim of Sund in thefe parts ; 

 and the ifland of Carmen is alfo faid to produce the like ; but in 

 the pariili of Quadfiorden in Nordland, it is fold at a rix-dollar 

 the tun, and ufed for painting houfes. Ol. Wormius, in his Muf. 

 cap. in. p. 4. makes fome mention of two kinds of red earth in 

 Ferro, which are of ufe in painting.

Cinnabar, or Minium- nativum, by all that I Can learn, has not 

 yet been found here, but federal places produce very good ockra, 

 or oker, which belongs to the iron fpecies, or is a kind of iron- 

 ruft. The famples in my poffeiiion are of Sulen on Sundmoer, 

 Qualoe in Ryefylke, and from Gedderen. Out of the gates of 

 Chriftiania, near the place of execution, a vein of very good oker 

 runs along the fide of the declivity of the mountain.

It may be prefumed from the copper-mines, that by a diligent 

 fearch, rightly dire&ed, a blue colour, like the ultramarine, or 

 fome fuch, might be found, but the country near Wardehuus in 

 Finland, on the borders of Ruilia, produces a foflile of a fine 

 fky-colour, of which a gentleman lately brought a fpecimen, by 

 which it appears very well to deferve a further infpedion, the 

 connoifTeurs being unanimous in their high eftimation of it. 



Near the before-mentioned houfe of Viul in Ringerige, i s AbI ackco 

 found a very black mining fine loam, and fo fine that it follows the l0Uf " 

 pencil with the fmoothnefs of foap, and may be ftiled the Nor-

* In fome places "urine is made ufe of for precipitating the fediment, which hin- 

 ders the allum from attaining its genuine clearnefs : whether this procefs has been 

 introduced here I know not. 



f I have been lately informed by Mr. Gabr. Heibeg, fuperintendant at Nordfiord, 

 and paftor at Gloppen, that near the houfes of Ryg and Eide, if not in other places,
