rebels, and a feeling not unlike headache is produced.

Further wonders are revealed every few thousand feet. At the mouth of
the next creek the coloring is different. The strata dips visibly, and
the marble, which has hitherto been exposed to view, is now beneath the
surface. The sandstone forms the river boundary, and rises at a sharp
angle from the water's edge. The river itself is narrow in consequence,
but the great valley is even wider at the top. The walls vary in height
from 2,000 to 8,000 feet, and in rainy seasons the water rushes down the
side in great profusion. Thousands of little rivulets join the main
stream, and add greatly to the volume of water. Sometimes the river will
rise four or five feet in a single night, upsetting all calculation, and
making navigation risky in the extreme. When, by chance, the sun is able
to penetrate into the depths of this canon, the kaleidoscopic effects
are exquisite, and cause the most indifferent to pause and wonder.

The discovery of an extinct volcano explains a great deal of the wonders
of the great canon. The volcano is examined by thousands of tourists,
this being one of the spots to reach which scientists are willing to
incur countless hardships and risks. No one can tell when the volcano
was active, but from the nature of the crater it is perfectly clear that
at one time it belched forth volumes of lava, which had a marked effect
on the formation of the rock and the lay of the land of the surrounding
country. Past the volcano, for many miles, the bright colors already
referred to are supplanted by more sombre hues. Occasionally there is a
little scarlet, and, as a rule, the sandstone is covered with the
mysterious substance brought out of the bowels of the earth by the now
silent, but once magnificently awful, mountains.

The exploring party to which we have referred, went through 600 miles of
canons, and found that no two miles were really alike. Finally, after
three months of hardship, they emerged into an open country, and became
almost frantic with joy. Never did country seem so beautiful, or verdure
so attractive, and the panorama of beauty which was presented to their
view caused them to shout with delight, and to offer up cries of
thankfulness for their ultimate deliverance from a series of hardships
and dangers which at one time seemed almost insurmountable.

The region also abounds with archaeological curiosities and remarkable
hieroglyphics. Many o
