t, after lecturing here, I packed
up, and started (not this time alone) for the North. Next day at noon
my wife and I found ourselves at Dalwhinnie, whence a drive of some
five-and-thirty miles brought us to the excellent hostelry of Mr.
Macintosh, at the mouth of Glen Roy.

We might have found the hills covered with mist, which would have
wholly defeated us; but Nature was good-natured, and we had two
successful working days among the hills. Guided by the excellent
ordnance map of the region, on the Saturday morning we went up the
glen, and on reaching the stream called Allt Bhreac Achaidh faced the
hills to the west. At the watershed between Glen Roy and Glen Fintaig
we bore northwards, struck the ridge above Glen Gluoy, came in view of
its road, which we persistently followed as long as it continued
visible. It is a feature of all the roads that they vanish before
reaching the cola over which fell the waters of the lakes which formed
them. One reason doubtless is that at their upper ends the lakes were
shallow, and incompetent on this account to raise wavelets of any
strength to act upon the mountain drift. A second reason is that they
were land-locked in the higher portions and protected from the
south-westerly winds, the stillness of their waters causing them to
produce but a feeble impression upon the mountain sides. From Glen
Gluoy we passed down Glen Turrit to Glen Roy, and through it
homewards, thus accomplishing two or three and twenty miles of rough
and honest work.

Next day we thoroughly explored Glen Glaster, following its two roads
as far as they were visible. We reached the col discovered by Mr.
Milne-Home, which stands at the level of the middle road of Glen Roy.
Thence we crossed southwards over the mountain _Creag Dhubh_, and
examined the erratic blocks upon its sides, and the ridges and mounds
of moraine matter which cumber the lower flanks of the mountain. The
observations of Mr. Jamieson upon this region, including the mouth of
Glen Trieg, are in the highest degree interesting. We entered Glen
Spean, and continued a search begun on the evening of our arrival at
Roy Bridge--the search, namely, for glacier polishings and markings.
We did not find them copious, but they are indubitable.

One of the proofs most convenient for reference, is a great rounded
rock by the roadside, 1,000 yards east of the milestone marked
three-quarters of a mile from Roy Bridge. Farther east other cases
occur
