that I was compelled to creep more than a mile on hands and knees.

In one spot I found an opening in the thorny sky where I could stand
erect, and on the further side of the opening discovered a small pool.
"Now, HERE," I said, "I must be careful in creeping, for the birds of
the neighborhood come here to drink, and the rattlesnakes come here to
catch them." I then began to cast my eye along the channel, perhaps
instinctively feeling a snaky atmosphere, and finally discovered one
rattler between my feet. But there was a bashful look in his eye, and
a withdrawing, deprecating kink in his neck that showed plainly as
words could tell that he would not strike, and only wished to be let
alone. I therefore passed on, lifting my foot a little higher than
usual, and left him to enjoy his life in this his own home.

My next camp was near the heart of the basin, at the head of a grand
system of cascades from ten to two hundred feet high, one following
the other in close succession and making a total descent of nearly
seventeen hundred feet. The rocks above me leaned over in a
threatening way and were full of seams, making the camp a very unsafe
one during an earthquake.

Next day the chaparral, in ascending the eastern rim of the basin,
was, if possible, denser and more stubbornly bayoneted than ever. I
followed bear trails, where in some places I found tufts of their hair
that had been pulled out in squeezing a way through; but there was
much of a very interesting character that far overpaid all my pains.
Most of the plants are identical with those of the Sierra, but there
are quite a number of Mexican species. One coniferous tree was all I
found. This is a spruce of a species new to me, Douglasii
macrocarpa.[14]
