Their feeding-grounds are among the most beautiful of the wild gardens, bright with daisies and gentians and mats of purple bryanthus, lying hidden away on rocky headlands and canon sides, where sunshine is abundant, or down in the shady glacier valleys, along the banks of the streams and lakes, where the plushy sod is greenest.

Here they feast all summer, the happy wanderers, perhaps relishing the beauty as well as the taste of the lovely flora on which they feed.
[Illustration: SNOW-BOUND ON MOUNT SHASTA.] When the winter storms set in, loading their highland pastures with snow, then, like the birds, they gather and go to lower climates, usually descending the eastern flank of the range to the rough, volcanic table-lands and treeless ranges of the Great Basin adjacent to the Sierra.

They never make haste, however, and seem to have no dread of storms, many of the strongest only going down leisurely to bare, wind-swept ridges, to feed on bushes and dry bunch-grass, and then returning up into the snow.

Once I was snow-bound on Mount Shasta for three days, a little below the timber line.

It was a dark and stormy time, well calculated to test the skill and endurance of mountaineers.
The snow-laden gale drove on night and day in hissing, blinding floods, and when at length it began to abate, I found that a small band of wild sheep had weathered the storm in the lee of a clump of Dwarf Pines a few yards above my storm-nest, where the snow was eight or ten feet deep.
