have still another. In the last-named locality,
the glacial tracks can be followed in various directions, some of them
descending toward the northwest from the heights of Helvellyn, others
moving southward toward Ambleside. In Wales the same kind of glacial
distribution has been observed; but, as Professor Ramsay has treated
this subject in full, I would refer my readers to his masterly work for
a further account of the ancient Welch glaciers. In Ireland I had also
opportunities of making extensive local investigations of glacial
action. I observed the centres of distribution in the neighborhood of
Belfast, in the County of Wicklow, and in Cavan.

But nowhere are these phenomena more striking than in Fermanagh County
about the neighborhood of Enniskillen, and more especially in the
immediate vicinity of Florence Court, the seat of the Earl of
Enniskillen. On the northern slope of Ben Calcagh are five valleys lying
parallel with each other and opening into the valley of Loch Nilly,
which runs from east to west at the base of the mountain. A road now
passes through this valley, and, where it crosses the mouth of either of
the five valleys rising towards the mountain-slope, it cuts alternately
through the two horns of a crescent-shaped wall which bars the lower end
of every one of them. These crescent-shaped mounds are so many terminal
moraines, built up by the five glaciers formerly descending through
these lateral valleys into the valley of Loch Nilly. They bore the same
relation to each other as the glaciers de Tour and d'Argentiere, the
Glacier des Bois with the Mer de Glace, the Glacier des Bossons and the
Glacier de Taconet, now bear to each other in the valley of Chamouni;
and were it not for the smaller dimensions of the whole, any one
familiar with the tracks of ancient glaciers might easily fancy himself
crossing the ancient moraines at the foot of the northern slope of the
range of Mont Blanc, through which the Arve has cut its channel, the
valley of Chamouni standing in the same relation to Mont Blanc as the
valley of Loch Nilly does to Ben Calcagh.

I have dwelt thus at length on the glaciers of Great Britain because
they have been the subject of my personal investigations. But the Scotch
Highlands and the mountains of Wales and Ireland are but a few of the
many centres of glacial distribution in Europe. From the Scandinavian
Alps glaciers descended also to the shores of the Northern Ocean and the
Baltic Sea.
