"Feeding! what could they be feeding on, when you say yourself that you left all kinds of 'green stuff' behind you long ago."
So _I_ thought, too, doubtless, by this time, most impatient reader; but on the screes at the head of the valley, Joseph showed me, for the first time, the plant on which these extraordinary animals in a great measure live. It has a thick green, trilobate leaf, and a flower so delicate and gauze-like, that one wonders how it can bear for a moment the harsh storms to which it is exposed. Its petals have a most curious crumpled appearance, and are of the softest pink imaginable--almost transparent. As for its class and order, you must go elsewhere for them; I know them not; nor the name either which the Latins would have called it if they had been aware of its existence. Joseph called it "gemsenkraut," or chamois herb, and that was enough for me.
Having finished our botanical investigations, we pushed on to the upper end of the valley, and found that the cliffs, and screes, and snow-patches looked uglier and steeper the nearer we approached them. However, there was no retreat--onward we must go, or be declared "nidding" through the length and breadth of the Tyrol.
Oh! those screes--those screes! lying at an angle of goodness knows how much with the horizon--sharp, slaty, angular pieces of stone, like savage hatchets, slippery as glass, glancing from under our feet, and casting us down sideways on their abominable edges, "sliddering" down by the ton, carrying our unfortunate persons yards below where we wanted to go, crashing and clattering, and then dancing and bounding far down into the valley, like mischievous gnomes, delighted with the bumpings and bruisings they had treated us to! How Joseph did anathematize! For my part, mine was a grief "too deep for swears!"
After crossing, still ascending, two or three beds of screes, we came to the edge of the first snow-field; not very broad, it is true, but lying at a higher angle than I ever thought possible, and frozen as hard as marble on the surface--one sheet of ice, with an agreeable fall of some hundred feet at its lower edge. We were in despair! We had now got excited and confident--our "blood was up;" and here came "the impossible to stop us."
