THE GLACIAL PERIOD.
Professor DentOn's Last Lecture OF,
GeO.Ogy.


Professor DentOn's Last Lecture OH
Geology.
Primitive Man Before the Ice Age.
Professor Denton gave the last Of his
Course Of lccturcs on Geology at Dashawa,
Hail ON the subject Of the "Glacial Period
and the Age Of Man." This, he said, is the
>trangest of all geologic ages. Il is mark
ID by beds OF sand, gravel, clay and bowl
.Iers from the size Oft mans head to that
# meeting .l,,usc. Whence cam. they: |
NJ N once supposed that thev saw in them
evidences of universal floud, the waters o.
which, sweeping over the world, heapel
these various beds and transported the
;oowl lcrs. With nm increased knowledge
i is impossible to accept such theory OF
their origin. Drift beds are not found fur.
ther south tran about the latitude ri 80 dc.
grce~, or the line Of Washington, Cincin
natl, st. Louis an KANSAS CITY, except t.
nigh Mountain regions. There are none il.
Tennessee, Alabama, Lo ,isiana and + xas.
As We go north the bowldcrs grow smaller
until they ceas. entirely;it Is tho same as
". 10 west, and it is n 1t until We 60 as tat
south Of the equator as We find these beds
,orth Of the equator that We discover SINH
lar dep SITS. An universal dc'ugc would
make beds as universal, but the fact that
they are confined to certain districts dis
MOVES the early and comm N theory OF
heir origin. An universal A>od covering
the tops Of al the mountains, is u physical
impos, Utility. II ali the moisture in our
atmosphere and on the surf;,c. OF our globe
were condensed and spread over the earth,
1t would not cover it three feet deep. But,
| in fact, these beds var. not made by waite,
ut all.
THE G,.AclAL BEDS.
When We discover tn glacial beds We
find that the material OF which they are
+ composed have never been sorted; We find
fine sand and coarse s;nI, small bowlders
and large ones piled in discriminatory to-
.ether. Wa er never does that |; it sorts the
material that it lays down. What has done
/ IT,? The answer i. ic,. We can catch tn.
$ ice doing ,ht very thing now. Various
k theories 10 account for the cold neces>ar,
