FORMATION OF GLACIERS.

waters, so as to present the form of a ridge-ancl-furrow
roof, something like the transept of the Crystal Palace.
The snow would, of course, accumulate in the furrows;
and would he so deep that the melting power of the
summer heat would not clear it away to the same
height as before; while on the ridges the snow would
lie so thinly, that it would be melted speedily, and the
visible snow-line there would be much above the
original height. Hence the apparent snow-line would
lose its regularity, and be a waving or zigzag line. If
these furrows were irregular, such as would be actually
formed by the running waters and sliding avalanches
wearing awTay the rock in some parts more than others,
this waving or zigzag line would have a corresponding
irregularity. The path of the avalanches would now
be clown these furrows, and as the rock forming the
sides of the furrows or troughs became weather-worn,
disintegrated by frost, or otherwise rendered friable, its
loosened fragments would be torn and dragged down,
with the sliding avalanches, and deposited in heaps at
the bottom, like those in the Romsdal (page 186).

Now let our supposititious great mountain-ridge
assume a more complex form: let there be huge
pyramids and peaks of rock sprouting irregularly from its
sloping side, and toothing the edge of its summit
ridge. There would be a labyrinth of hollows
between these peaks, valleys, and basins of the upper
ground above the snow-line. In these the snow Avould
rest and accumulate till they were filled to overflowing;
it would fill up the communicating avenues between
