Puzzling Aspects of Utah'S Won.

ONE OF NATURES MYSTERIES

Antelope Island.
The Great Salt lake of Utah con
tinues to be one of the greatest mvs-
terleS OF nature. For sixty years its
rise and fall have been studied by sci.
entists in an effort to account for the
changes, but rs yet they have reached
no satisfactory solution of the prob

Of the decrease in It's depth.

ception Of few shallow pools Of wa.

nected with it will be solved.
In its dimensions the lake is really a
sea. it being above seventy-five miles
In length and fifty miles across at its
greatest width, containing, therefore,
over 1000 square miles of surface

The buoyancy of the water is such
that it is almost impossible for one
to remain on his feet at greater
depth. his body being lifted up as

Indeed, 1t 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.
ton 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
sists 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 1t is far less
than that annually poured into the
lake from the rivers and crooks enter
ing It.

ly equal to a depth Of four inches of
the present area. This is very small
proportion of the volume of water that
enters 1t 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 its depth, and the
records show that actually 1t has fallen

other streams have contributed a

number Of years ago. 1t Is said, a
sailing vessel loaded with sheep
CHANGED to approach too near the
"maelstrOm," and despite the strong
breeze that was blowing the force Of
the water was greater than the power
Of the sails. the vessel being drawn
into the middle Of the disturbance and

a few hundred feet away, not one Of
the animals escaped and most Of the
carcasses went under never to appear
again.
While the buoyancy Of the water is
so great that 1t will support a person
without aid, the boats designed for use
upon the lake must be constructed es
pecially to counteract this feature. The
ordinary wooden vessel when empty
Is actually too light to be navigated
with safety upon it. since such small
portion Of 1t would be immersed. Care
must therefore be taken, especially in
the building of sailboats. lest they be
top heavy. For this reason navigation
Is dangerous on the lake even when
there Is only a moderate wind, unless
the sailing vessel is loaded heavily so
that 1T sits deep enough in the water
to counteract the buoyant tendency
