H.; thence northwest, it crossed the
Mississippi river at St. Louis, and fol-
lowed the Missouri and Kansas rivers
to Topeka, where it swung northward
across the eastern parts of Kansas
and Nebraska, and through central
Dakota to near the Canada line;
thence proceeding with a long loop
where it crossed the Rocky mountains
the Pacific ocean. If one had ap-
preached this line during the glacial
period anywhere from the south, he

conditions of Greenland, and found
them continuous for thousands of
miles. Alaska still retains the stumps
Of this great glacier, several hundred
square miles being covered by the
Muir glacier alone, and still larger
area by the Malaspina glacier, which
comes down from Mount St. Elias.
In Europe the ice fields radiated from
the Scandinavian peninsula, extending
across the North sea to southern Eng
land. and across the Baltic to central
Germany and southeastern Russia.
In thinking of the glacial period it
should be kept clearly in mind that
glacial ice is simply compressed snow.
Glaciers are formed wherever there is
a snowfall which exceeds the melting
power of the warm season. Everyone
is familiar with the fact that a snow
ball may be made as hard as ice by
sufficient pressure in the hands,
That ice in great masses could flow
like cold tar or molasses or any other
semi-f1uid seemed, until short time
ago, impossible, and did not enter into
the thought of mankind. But about
20 years ago it was demonstrated in
Switzerland that the ice was actually
moving down the valleys, proceeding,
not like an avalanche, but creeping
with true flow, and carrying on it's
back and frozen into its mass frag-
ments of rock of varying sizes, some
of them being as large as a small
house. Under the lee Of one of these
rock masses on top of the Aar glacier

many of his important observations.
The great extent of this glacial
movement in former times was shown
by the distance which some of these
powders had been carried
In North America the transportation
of powders by glacial ice has been
even more remarkable. The back.
