EXTERNAL APPEARANCE OF GLACIERS.

Thus far we have examined chiefly the internal structure of the glacier;
let us look now at its external appearance, and at the variety of
curious phenomena connected with the deposit of foreign materials upon
its surface, some of which seem quite inexplicable at first sight. Among
the most striking of these are the large boulders elevated on columns of
ice, standing sometimes ten feet or more above the level of the glacier,
and the sand-pyramids, those conical hills of sand which occur not
infrequently on all the large Alpine glaciers. One is at first quite at
a loss to explain the presence of these pyramids in the midst of a
frozen ice-field, and yet it has a very simple cause.

I have spoken of the many little rills arising on the surface of the ice
in consequence of its melting. Indeed, the voice of the waters is rarely
still on the glacier during the warm season, except at night. On a
summer's day, a thousand streams are born before noontide, and die again
at sunset; it is no uncommon thing to see a full cascade come rushing
out from the lower end of a glacier during the heat of the day, and
vanish again at its decline. Suppose one of these rivulets should fall
into a deep, circular hole, such as often occur on the glacier, and the
nature of which I shall presently explain, and that this cylindrical
opening narrows to a mere crack at a greater or less depth within the
ice, the water will find its way through the crack and filter down into
the deeper mass; but the dust and sand ca
