Another item which adds to the suggestion of the illimitable spread of sage-brush country, like the sea, is the way the sparse forests of the mountain-tops appear to be islanded by it. For the sage-brush extends on across the Great Basin, it stretches into Montana and south to Arizona and New Mexico, it works about the lower end of the Rocky Mountains and well into the great central plain. The ranges lie thick in it as ocean swells, as I have said, and stepping from crest to crest has come the fox-tail pine, _Pinus flexilis_, all the way from Humboldt Mountain to San Jacinto. A sinewy, thinly-branched species, as straight-backed as an Indian, it has little affinity for its noble congeners of the Sierra forests, but keeps to the dry and open ridges, nourished by clouds and by infrequent shallow snows. With it, but at lower levels to which the _flexilis_ will never come, is found frequently the one-leaved piñon pine, the food-crop of the wild tribes. But the piñon is a pushing sort, it establishes itself upon the slightest invitation. There is a story told in the desert of how this grey, round-headed tree was once a very great _capitan_, who, in order that his death might be as beneficent to his people as his life had been, was changed into the foodful pine. Whether the legend is true or not, certain it is that if you sit down by a piñon, wherever found, and stay long enough, you will see Indians. They might come in the Spring looking for _taboose_, or later for willows and grasses for basketry, for seeds of sunflower and chia, to shoot doves by the water-holes or to hunt chuckwallas. A chuckwalla is a lizard, a kind of dragon in miniature, barred black and white, and as offensive to look at as he is harmless, in fact very good eating and not too plentiful. Mojaves, Shoshones, Paiutes, Pimas, all the tribes of the sage-brush country, have this in common, that they live very close to the earth; roots, seeds, reptiles, thick pads of the cholla cactus, even the grass of the field, serve them. They look, indeed, as though they had been made of the earth on the very spot that produced them, of the black rock, the brown sand, and the dark water that collects in polished basins of the wind-denuded ranges.
