The Great Salt lake Of Utah con.
tinues to be one Of the greatest mys.
teries Of nature. For sixty years its
rise and fall have been studied by sci
entists In an effort to account for the
changes. but as yet they have reached
no satisfactory solution Of the prob
lem as to, what is the principal cause
Of the decrease in it's depth.
Those familiar with its depth and
the shrinking in its size each year
assert that at the end of twenty years
or so the bed Of the lake will be near.

ception of few shallow pools Of wa
ter. Then perhaps the mystery con-
nected with 1t will be solved.
In its dimensions the lake is really

In length and fifty miles across at its
greatest width, containing, therefore,
over 1000 square miles Of surface.
Near the shores the water is SO shall
low that there are places where one
may wade out from the beach for a
distance of mile, yet will not be i'm
mersed up to his shoulders.
The buoyancy Of the water is such
that 1t is almost impossible for one
to remain on his feet ut a greater
depth, his body being lifted up as a
strip OF wood thrown into the water
in vertical or oblique direction like

horizontal position.
Indeed, it is believed the Great Salt
lake will support more weight to a
given volume of water than even the
Dead sea, to which in many respects
1t bears striking similarity.
The large quantity of salt in solu-
tion is the principal reason for the
buoyancy. AS the lake recedes its
bottom Is shown to be composed of
heavy crust Of salt, which is almost
pure, lying upon stratum that con-
ststs chiefly of sand. In this respect
the bed of the lake is similar to some
Of the deserts in the southwest which
once contained bodies Of water equal
in size to that in Utah or even larger.
1t is known that the Great Salt lake
loses large quantity of water yearly
by evaporation. but estimates of this
quantity indicate that it is far less
than that annually poured into the
lake from the rivers and creeks enter
ing it.
So far as is known no natural outlet
exists, but the lake supplies an irrigat-
ing system in the country adjacent
that requires quantity of water year
ly equal to a depth Of four inches of
the present area. This is a very small
proportion of the volume of water that
enters it through it's feeders. so the
scientists know the water escapes in
some other manner than by the irri-
cation canal or by evaporation.
This is proved by the fact that the
increase in the quantity that enters
the lake at rainy season at times
does not increase it's depth, and the
records show that actually it has fallen
Immediately after the Jordan and
other streams have contributed
larger volume than usual.
Near what is called Antelope island
is an indication that a subterranean
opening exists. Frequently the waters
near the island are so violently dis
turbed that people in the vicinity call
this place the "maelstrom" and care

While the buoyancy of the water is
