OF LOCHABER. 35 



falling at once fifteen or twenty feet. This, as will be seen by 

 reference to the map, is the very same High Glen, upon the 

 other extremity of which I had already occasion to touch, in 

 my description of Glen Gluoy, where I mentioned it as afford- 

 ing a vista from the head of that valley, into Glen Roy, through 

 Glen Turret. 



The two shelves, (Shelf 3d and Shelf 2d), in winding from 

 Glen Roy into the south-western side of Glen Turret, are ex- 

 panded on a wide, and greatly elevated inclined plane, cover- 

 ed with peat-moss. They are consequently indistinct for a 

 time, and they do not become very manifest, until they cross 

 the stream coming from the High Glen y and lay hold of the 

 steeper hill. They are then particularly well defined, and are 

 very clearly marked in their progress all around the bendings 

 of the mountains of Glen Turret, till they return by its north- 

 west side, and sweep around the face of Tom-Bhran into Glen 

 Roy. But the most interesting part of their course through 

 Glen Turret, is that where they cross the tributary stream, as 

 it issues from the High Glen. In this place, Shelf 2d is found 

 on examination to touch exactly on the uppermost waterfall, 

 at an elevation about twelve feet below that of Shelf 1st, or 

 the Glen Gluoy Shelf. On tracing up the course of the little 

 stream above this waterfall, it is found to run through the bot- 

 tom of the High Glen, with a gentle current, without creating 

 any excavation, and displaying no section, though the surface 

 of the rock is sometimes descried in the water. It may be 

 about a mile from the highest cascade, upwards, in which dis- 

 tance it has an aggregate fall of about twelve feet. It seems 

 to have its origin, partly from springs on the sides of the hills, 

 and partly from the moisture of a flattish mossy meadow, 

 which continues to have an almost imperceptible rise for about 

 on? hundred yards, till, at a point, which is not more than the 

 thickness of the moss higher than Shelf 1st, the level of the
