Glaciers.

Webster's dictionary tells us that
ice, formed in deep but elevated valleys,
or on the sides Of the Alps or other
mountains" But perhaps we can bet
ter imagine what it is by thinking what
a river as wide and deep, though not as
long as the Hudson, would be if frozen
into one solid mass Of ice, and instead
of having a Fat surface were TO round
up highest in the middle, rough and
broken as the ocean in a storm. We
shall not tell YOU now how these "ice
rivers" which are found mostly in
Greenland. Iceland, Spitzbergen, and
Switzerland commence and grow. That
is one OF the very interesting things you
big boys and girls find in your physical
biographies" and that you little folks
will be delighted to study about when
you are older. And now many such
things there are, and how happy you
will be when you can learn them all
We can only select one glacier, and
tell you little about it, and that we
hope will give you some idea of all the
others.
i'm the same valley that is now cover
ed with the glacier of Sermitsialik in
Greenland. there were once green grass,
sparrows chirruping among the branches
of the stunted trees, and herds of rein
deer browsing upon its abundant pas
lures. This must have been about two
hundred and fifty years ago, and natu-
ralists could tell US about the progress
of the glacier since that time when the
ice-stream first began to travel towards
the sea, which it has now reached
through the gorge in the mountain
chain ten miles back from the shore.
For, strange though it may seem, this
flood OF solid ice is always steadily NOV
ing, whether over steepest precipices or
across level plains, carrying with it the
largest masses Of rock, and grinding
smaller ones to dust overwhelming the
green pastures and the stunted trees,
until at last il reaches the sea. But even
here it does not stop.
The bed OF the sea is but continue.

Glaciers have long been counted

we'll as many travellers for the mere low
of adventure, have incurred fearful
dangers in exploring them. The SUI

great cracks, or crevaSSeS as they ar
called, hundreds of feet deep, which
can only be crossed on frail and slipper
bridges of ice where a single missile
would be instant death to the DARN
