BEN-VORLICH

pyrites, as an occasionally imbedded fossil. Strata 

 whose characters correspond with those of the 

 rock at the summit of Ben-Ledi, also are found. 



After entering the mica-slate country at the 

 place now mentioned, nothing remarkable appears 

 immediately along the road, before we arrive at 

 Loch-Earn- head. On the north of the water, a- 

 bout a mile from the inn, foliated granular lime- 

 stone of a bluish-grey colour occurs, disposed in 

 thin strata or layers, and much penetrated with 

 veins of quartz and calcspar. The mica-slate in 

 which it is imbedded, seems ,to border on clay- 

 slate ; but is weathered to such a degree, that I 

 was unable to find a proper specimen, from which 

 I could with certainty give its description. 



BEN-VOKLICH AND STU I O A-C H ROI N, 



— -on the south side of Loch-Earn, are mountains 

 of a similar construction with Ben-Ledi, formerly 

 described ; lying to the north-east of it, in the 

 common direction of the great strata, and conse- 

 quently presenting, as might be expected, the 

 usual succession of primitive rocks. From the 

 house of Ard-Vorlich on the edge of the water, 

 the ascent is regular and not difficult, till about a 

 mile and a half from the summit of Ben-Vorlich ; 

 where the rock begins to be more uncovered and 

 precipitous, and the geognosy of the mountain 

 may be more*distinctly ascertained. Mica-slate
