not 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 well- ^ r ™ f n it d)e 

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

 MorafTes ; 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 parifh of Sund in thefe parts ; 

 and the iiland of Carmen is alfo laid to produce the like ; but in 

 the parifh of Quselfiorden in Nordland, it is fold at a rix-dollar 

 the tun, and ufed for painting houfes. 01. 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 feveral places produce very good ockra, 

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

 ruft. The famples in my pofleffion 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 Abluec ° ; 

 fearch, rightly directed, a blue colour, like the ultramarine, or ^ 

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

 Finland, on the borders of Ruffia, produces a foffile of a fine 

 /ky-colour> of which a gentleman lately brought a fpecimen, by 

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

 connoiffeurs being unanimous in their high eftimation of it. 



Near the before-mentioned houfe of Viul in Ringerige, is Abla ck co- 

 found a very black fhining fine loam, and fo fine that it follows the 

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