terraces of gravel to which Mr. Lucy’s Paper referred occur 
near the outlets of Loch Roshk and Loch Ledgowan, which 
lochs are separated by the high mountain of Leonach. There 
are three well marked terraces, of which the uppermost is by 
far the largest. Its height is about sixty feet; the second 
terrace is twelve feet, and the third six feet; this latter is quite 
recent. The upper terrace is covered with peat, in some places 
four feet thick, and in it are large roots of trees. The second 
terrace is also covered with peat, but of less thickness. In 
both terraces are large boulders of quartz, granite, gneiss, trap, 
Laurentian and metamorphosed Silurian rocks, full of mica. 
There was abundant evidence of ice-action all around. The 
gathering-ground of the ice which passed into Loch Roshk was 
Glen Docharty, Ben Fin, and the adjacent mountains; and 
that which passed into Loch Ledgowan was derived from the 
mountains parallel to the loch. The ice-borne masses formed 
moraines, by which the water was dammed back to a point at 
which it overflowed, and in process of time planed down the 
debris until they formed the present level surface of the upper 
terrace. In process of time this terrace was cut through to the 
depth of sixty feet, when another barrier of smaller size was 
formed by the same agency, and a period of rest ensued. A 
similar process was again repeated, and the lower terrace was 
formed, which represents the highest flood level of the present 
rivers. Mr Lucy, after some remarks on the Geology of the 
district, which corresponds with that of Sutherland, with the 
exception of the absence of lias and oolite, called attention to 
the evidences of ancient forests, as shewn in the huge roots of 
trees found everywhere under the surface soil, and in the peat 
deposits, as contrasted with the present remarkable absence of 
trees. At Ledgowan there are evidences of four successive 
forest growths, one above the other. Mr Lvucy referred the 
age of the peat-forest to post-glacial times, after the period of 
the low-level gravels, and quoted a French writer, M. Beneranp, 
in support of his views.
