mer, a pale lime-ftone, purple or garnet- 

 coloured grains of quartz, and fome tran- 

 fparent quartz. Sometimes the reddifli vi- 

 trefcent ipar is the moft abundant, and lies 

 in long ftripes of fmall hard grains. Some- 

 times the fine black glimmer abounds more 

 than the remaining conftituent parts; and 

 thefe two laft kinds of ftone generally run 

 in alternate ftripes. The white lime-ftone 

 which confifts of almoft invifible particles, 

 is mixed in among them. The garnet- 

 coloured quartz grains appear here and 

 there, and fometimes form whole ftripes. 

 They are as big as pin's heads, round, 

 (hining, and ftrike fire with fteel. All 

 thefe ftones are very hard, and the moun- 

 tains near the fea, confift entirely of them. 

 They fometimes ly in almoft perpendicu- 

 lar ftrata, of ten or fifteen inches thick- 

 nefs. The ftrat.a, however, point with 

 their upper ends to the north-weft, and go 

 upwards from the river, as if the water, 

 which is clofe to the fouth-eaft fide of 

 the mountains, had forced the ftrata to 

 lean on that fide. Thefe mountains con- 

 tain very narrow veins of a white, and 

 fometimes of a greenim, fine, femidiapha- 

 nous, foft fpar, which crumbles eafily into 

 grains. In this fpar thry very frequently 

 fpecks, which look like a calamine 



blend.
