green with greyifh veins, likewife an azure marble. This is eafier 

 to the chiffel than in moft places ** 



4. Salthellen, four Norway-miles from Bergen, affords a white 

 marble, and eafily wrought, but is not fo firm as that of Hope- 

 holm, and breaks into longifh blocks; it alfo affords a grey and 

 white, likewife a dark grey flreaked with white. 



5 . Hillebrud, feven Norway-miles from Bergen, the marble 

 of this quarry is white, with a yellowim tinge ; it likewife pro- 

 duces a light- blue and white, both kinds very compleat, and in' 

 large blocks. 



6. Stourfoen-quarry, one of our miles from the monaftery of 

 Halfnoe, yields black-marble fludded with white fpots, and its 

 blocks are large and compact 



7. Selloe, on the other fide of this monaftery, produces blue 

 and white marble, in larger blocks than are to be met with any 

 where. 



To this tribe of ftones belongs likewife the touch-ftone, Lapis- 

 lydius, being a kind of black-marble ; alfo alabafter, which I have 

 met with in my journey to Sundmoer, near Borgenfund, but of a 

 greyifh caft, and only in fmall pieces, lying as an infufed adven- 

 titious matter betwixt the ftrata of hard pebbles ; by the peafants 

 it is called Hejetel, under which name I have already fpoke of it in 

 the 2d chapter, concerning the origin of mountains. Under this 

 fpecies may alfo be comprehended the feveral kinds of fpar, or 

 other mining ftones, like what is called Katzenfilber, which are 

 eafily reducible to a white powder, as are the chalk-ftone, ce- 

 ment-flone, and flucco-ftone, to which ufe likewife the firic~bures 

 of marble, which fly off in the quarries are applied.

 for building or for grind-ftones, which laft are in greateft perfec-

 white veins were intermixed, in a more beautiful manner than any I had ever feen j 

 the only defeat is the foftnefs of the green veins, which hinders a perfect polifli.
