wn. The day is very hot and my coat was left in
camp, so I have no linings to tear out. Then it occurs to me to cut off
the sleeve of my shirt and tie it up at one end, and in this little sack
I collect about a gallon of pitch. After taking observations for
altitude, I wander back on the rock for an hour or two, when suddenly I
notice that a storm is coming from the south. I seek a shelter in the
rocks; but when the storm bursts, it comes down as a flood from the
heavens,--not with gentle drops at first, slowly increasing in quantity,
but as if suddenly poured out. I am thoroughly drenched and almost
washed away. It lasts not more than half an hour, when the clouds sweep
by to the north and I have sunshine again.

In the meantime I have discovered a better way of getting down, and
start for camp, making the greatest haste possible. On reaching the
bottom of the side canyon, I find a thousand streams rolling down the
cliffs on every side, carrying with them red sand; and these all unite
in the canyon below in one great stream of red mud.

Traveling as fast as I can run, I soon reach the foot of the stream, for
the rain did not reach the lower end of the canyon and the water is
running down a dry bed of sand; and although it conies in waves several
feet high and 15 or 20 feet in width, the sands soak it up and it is
lost. But wave follows wave and rolls along and is swallowed up; and
still the floods come on from above. I find that I can travel faster
than the stream; so I hasten to camp and tell the men there is a river
coming down the canyon. We carry our camp equipage hastily from the bank
to where we think it will be above the water. Then we stand by and see
the river roll on to join the Colorado. Great quantities of gypsum are
found at the bottom of the gorge; so we name it Gypsum Canyon.

_July 27.--_We have more rapids and falls until noon; then we come to a
narrow place in the canyon, with vertical walls for several hundred
feet, above which are steep steps and sloping rocks back to the summits.
The river is very narrow, and we make our way with great care and much
anxiety, hugging the wall on the left and carefully examining the way
before us.

Late in the afternoon we pass to the left around a sharp point, which is
somewhat broken down near the foot, and discover a flock of mountain
sheep on the rocks more than a hundred feet above us. We land quickly in
a cove out of sight, and away go all the hunters with t
