A REVIEW.
Probably / ought not to talk shop
here. But II | were teaching this sub
iect matter to a class and desired to
find whether or not they understood, |
would proceed as follows:
Did you ever battle in Great Salt
lake? Why can't you sink in it? Salt
water is much heavier than fresh
water. Weigh quart of fresh
water and a quart of very
salty water, and account for the
difference. The lake water stands
most OF the summer at so degrees. Have
you ever heard of ocean bathing in
sea so warm? In tropical seas only the
water is sometimes so to SO degrees.
Does the water get either so warm or
so cold as the air? Give reasons.
What others of our lakes are salty?
Why? Which are fresh? Why?
Four principal shore lines extend
from the present lake level to LOCO
feet above it; the highest is called
Bonneville: another is named the Provo
line; between these two are fainter,
more ancient, ones called the Inter
mediate; and lowest OF all. 300 feet
above the present lake another called
the Stansbury, is the most recent. How
many OF these can you find? From
their relative ages, do you think the
lake sometimes rose and sometimes
fell? Why? Is there level bench land
at the mouth of your canyon? Does II
resemble delta formation? Or is It
mound shaped-produced by glaciers
and Hoods? Any level plains in your
district? Following is the substance
OF Major Powells history of Lake Bon
neville: First the waters were low,
occupying as Great Salt Lake now does,
only IA limited portion of the bottom
of the basin. Then they gradually rose
and spread, forming an inland sea,
nearly equal to Lake Huron in extent,
with a maximum depth of a thousand
feet. Then the waters fell and the
lake not merely dwindled in size but
absolutely disappeared, leaving a plain
even more desolate than the Great Salt
Lake Desert of today. Then they
again rose, surprising even their FOR
mer height, and eventually overlooked
the basin at its northern edge, sending
a tributary stream to the Columbia
River and last there was n second re-
| cession, and the waters shrunk away
until now only Great Salt Lake and
| two smaller lakes remain"
