with Its stupendous scenic effects, Its
beauty and its grandeur, is little cal
cnlated to raise practical thoughts in
the minds of most of Its beholders
But anyone With II touch of the en-.
gineer In his makeup who gazes into
this great chasm must marvel at the
tremendous energy that has been ex.
erted by running water In carving Its
way more than mile In depth through
rocks Of various degrees Of hardness
And into his mind, as his eye gauges
the vast canyon. IL sure to come tile
question: What has become Of the
billions Of cubic yards Of material
that once filled this enormous pit;
The lower Colorado country--a region
Of fascination despite Its deserts and
marshes, its mud volcanoes and shift.
Ing sand-dnnes-is the answer; for II
is truly the creature of the river,
built from the countless tiny grains Of
sand and silt that its waters have
brought down through the centuries.
The mouth Of the Colorado is one
Of the least-kn0wn regions Of North
America. Only 90 miles to the north
In an air line the American town Of
Yuma has existed for the better part
Of century, and through It passes
one OF the principal. transcontinentaI
railroads Of the United States; while
little more than n hundred miles 10
the west lies the rich valley of south

There are physical difficulties In
reaching the mouth Of the Colorado; /;
but the chief lmpediment is an imag-
mary line-the Mexican border. For
while the Colorado Is essentially a
river Of the United States and
traverses Its soil for some nineteen.

sea which the Colorado reaches is the
long narrow Gulf Of California whose
northern end, into which the Colo

sands and rocky. largely barren noun

the mouth Of the Colorado, the shores
Of the gulf form desolate region, al

Of which are half-civilized Indians.

wonder.
One Of the striking features of the
lower Colorado country Is just north
west Of the river opposite Yuma,
where Is to be found one OF Americas

Not only has the Colorado created
deserts; II has made what may be
considered their opposites, marshes,
as well. Below Yuma, where the
river emerges from the rough coun-
