OF LOCHABER. 23 



which will be easily understood from the map. I mean to be- 

 gin at Lowbridge, and describe the whole of Glen Roy up- 

 wards. I shall then give a general account of the Glen-mor- 

 na-Albin, or Great Glen of Scotland, the necessity of which 

 will appear, when I come to the theoretical part of my paper. 

 Proceeding from thence south-westwards, I shall describe the 

 more open part of the country about the Spean. I shall trace 

 Glen Roy upwards to the Loch of Spey ; return to the mouth 

 of Glen Turret, and describe that valley, and the High Glen 

 of its little tributary stream upwards, to where it opens at its 

 north-western extremity into the head of Glen Gluoy. Re- 

 turning to the mouth of Glen Roy, I shall describe the whole 

 of Glen Spean, Loch Laggan, and Loch Treig ; and shall con- 

 clude with a description of those very satisfactory and convin- 

 cing appearances in the bottom of Glen Spean, which are 

 numbered in the map with the figures 5, 6, and 7. and which 

 can be viewed in no other light than as being three inferior 

 shelves, each successively of lower level than that numbered 

 as above it. 



The general direction of Glen Gluoy is nearly S. E. and 

 N. W., and its length is about seven or eight miles. Its 

 mouth opens into the Great Glen of Scotland at Lowbridge, 

 and it pours its stream into Loch Lochy, a little way below 

 that place. The hills bounding Glen Gluoy approach one 

 another very closely, leaving no more than room for the river 

 to run in the bottom. They are very lofty and steep, particu- 

 larly at Lowbridge, over which they rise with a bold front, 

 there forming the side of the Caledonian Glen. They are in 

 general covered with a short grass, and, like all the rest of the 

 hills in this neighbourhood, afford excellent sheep-pasture. 

 From the extreme narrowness of this glen, its shelf is not ea- 

 sily viewed. I am, however, enabled to describe it, by having 

 paid two visits to the valley, in the course of which, I looked 



into
