its edges are fringed with plantations and verdure, 

 and many charming views occur. In particular, 

 near the place where the course of the river 

 bends to the west above the bridge, the slaty stra- 

 ta, which here contain veins of quartz, and con-

 light having been spent in the fatiguing circuit 

 of the whole mountain, which, on this occasion, 

 was performed in one day. I afterwards return-

 its identity with that portion of the summit-rock 

 which is not porphyritic. A vein of lead-ore, 

 four or five inches thick, is mentioned in |he ex- 

 cellent statistical account of the parish of Kil-
