have left their marks. Every gravel- and boulder-bed has been
desperately riddled over and over again. But in this region the pick and
shovel, once wielded with savage enthusiasm, have been laid away, and
only quartz-mining is now being carried on to any considerable extent.
The zone in general is made up of low, tawny, waving foot-hills,
roughened here and there with brush and trees, and outcropping masses of
slate, colored gray and red with lichens. The smaller masses of slate,
rising abruptly from the dry, grassy sod in leaning slabs, look like
ancient tombstones in a deserted burying-ground. In early spring, say
from February to April, the whole of this foot-hill belt is a paradise
of bees and flowers. Refreshing rains then fall freely, birds are busy
building their nests, and the sunshine is balmy and delightful. But by
the end of May the soil, plants, and sky seem to have been baked in an
oven. Most of the plants crumble to dust beneath the foot, and the
ground is full of cracks; while the thirsty traveler gazes with eager
longing through the burning glare to the snowy summits looming like hazy
clouds in the distance.

The trees, mostly _Quercus Douglasii_ and _Pinus Sabiniana_,
thirty to forty feet high, with thin, pale-green foliage, stand far
apart and cast but little shade. Lizards glide about on the rocks
enjoying a constitution that no drought can dry, and ants in amazing
numbers, whose tiny sparks of life seem to burn the brighter with the
increasing heat, ramble industriously in long trains in search of food.
Crows, ravens, magpies--friends in distress--gather on the ground
beneath the best shade-trees, panting with drooping wings and bills wide
open, scarce a note from any of them during the midday hours. Quails,
too, seek the shade during the heat of the day about tepid pools in the
channels of the larger mid-river streams. Rabbits scurry from thicket to
thicket among the ceanothus bushes, and occasionally a long-eared hare
