ot until the Glen Spean glacier had retreated to the hills east of
Loch Laggan that the glacier of Loch Treig could form a barrier across
Glen Spean, and thus dam the waters in Glen Roy which produced the
parallel roads. The marks left by the great Glen Spean glacier in the
valley are mistaken by Professor Jamieson for indications, that, in its
greatest extension, the glacier of Loch Treig not only advanced across
Glen Spean, but divided into two branches, one moving westward down Glen
Spean, the other eastward up Glen Spean, as far as Loch Laggan. Any one
sufficiently familiar with existing glaciers to compare their action
with the phenomena referred to above will at once see the impossibility
of such a course for any glacier coming down from Loch Treig. At the
time the Grampians had become a separate centre of glacial action a
great glacier must have moved down, towards the Caledonian Canal,
through Glen Spean, receiving as tributaries lateral glaciers not only
from Loch Treig and Glen Roy, but also from all the other minor lateral
valleys emptying into Glen Spean, the largest of which must have come
from the range of Ben Nevis,--just as the great glacier of the valley of
the Rhone once received as tributaries all the glaciers coming down into
that valley from the southern slope of the Bernese Oberland, and from
the northern slope of the Valesian Alps, and at one time also from the
eastern slopes of the range of Mont Blanc. And when the large glacier
occupying the lower, and therefore warmer, level gradually disappeared
and retreated far away to levels where it could maintain itself against
the effect of a returning milder climate, the opening spring of our era,
as we may call it, the lateral glaciers, arising from the nearer high
grounds, could extend across the valleys, but not before.

UNDER THE CLIFF.

"Still ailing, Wind? Wilt be appeased or no?
Which needs the other's office, thou or I?
Dost want to be disburthened of a woe,
And can, in truth, my voice untie
Its links, and let it go?

"Art thou a dumb, wronged thing that would be righted,
Intrusting thus thy cause to me? Forbear!
No tongue can mend such pleadings; faith, requited
With falsehood,--love, at last aware
Of scorn,--hopes, early blighted,--

"We have them; but I know not any tone
So fit as thine to falter forth a sorrow:
Dost think men would go mad without a moan,
If th
