BEN-MORE. 307 



The apparent quantity of this ore, would hardly 

 encourage an attempt to work it. Many of the 

 strata on the same ridge, in decomposing, split in 

 lines that cross the real course of the rock, almost 

 at right angles ; a circumstance which is apt to 

 mislead the hasty observer, in estimating the dip 

 and inclination. Towards the base, greyish- 

 black hornblende-rock, slightly porphyritic, is 

 found ; and beds of beautiful dark-green horn- 

 blende-slate, with a shining lustre, and of red fel- 

 spar-porphyry, having crystals of felspar, quartz, 

 and mica, present themselves in the situation 

 assigned them by the geognosy. 



TYNDRUM AND KINgVhOUSE. 



Leaving Ben-More, we come to Strathfillan, of 

 which the mineralogy may be soon dispatched, as 

 it is every where covered with soil and culture, and 

 offers little to the notice of the scientific travel- 

 ler, (except a bed of bluish -grey limestone, which 

 is granular-foliated, and of great thickness, not 

 far from Crian-Larich), till we arrive at Tyndrum, 

 where the Clifton lead-mine is not unworthy of 

 attention. Many years have elapsed since it was 

 first opened. The concern succeeded for some 

 time, but at last failed. A few years ago it was re- 

 sumed, and again abandoned ; probably more 

 from the want of capital, than of productiveness
