These, as they are marshalled on each side or
shore of the glacier, form the “lateral moraines.”
It often happens that two confluent valleys are
filled with glaciers, which meet like the meeting
of waters, and swell into a larger stream; the
lateral moraines of the inner sides of each unite,
and thus a medial moraine is formed. Finally,
these moraines, travelling always onwards, reach,
stone by stone, to the bottom of the glacier, and
there they are deposited, forming the “terminal
moraine,” which sometimes amounts to a huge
accumulation.
I am sorely tempted to continue this subject;
to explain how great masses of rock float upon
this icy sea, and are upreared on crystal pedestals;
how an errant butterfly, chilled to death by the
cold glacier blast, falls upon the ice with outspread
wings, and how the sun so largely warms its fallen
favourite as to dig for it a little grave, an ice-cup
of oval shape with longer axis lying due north
and south, and deepest at the north, and lying
