To civilized people from corn and cattle and wheat-field countries the canon at first sight seems as uninhabitable as a glacier crevasse, utterly silent and barren.  Nevertheless it is the home of a multitude of our fellow-mortals, men as well as animals and plants.  Centuries ago it was inhabited by tribes of Indians, who, long before Columbus saw America, built thousands of stone houses in its crags, and large ones, some of them several stories high, with hundreds of rooms, on the mesas of the adjacent regions.  Their cliff-dwellings, almost numberless, are still to be seen in the canon, scattered along both sides from top to bottom and throughout its entire length, built of stone and mortar in seams and fissures like swallows’ nests, or on isolated ridges and peaks.  The ruins of larger buildings are found on open spots by the river, but most of them aloft on the brink of the wildest, giddiest precipices, sites evidently chosen for safety from enemies, and seemingly accessible only to the birds of the air.  Many caves were also used as dwelling-places, as were mere seams on cliff-fronts formed by unequal weathering and with or without outer or side walls; and some of them were covered with colored pictures of animals.  The most interesting of these cliff-dwellings had pathetic little ribbon-like strips of garden on narrow terraces, where irrigating-water could be carried to them—­most romantic of sky-gardens, but eloquent of hard times.

In recesses along the river and on the first plateau flats above its gorge were fields and gardens of considerable size, where irrigating-ditches may still be traced.  Some of these ancient gardens are still cultivated by Indians, descendants of cliff dwellers, who raise corn, squashes, melons, potatoes, etc., to reinforce the produce of the many wild food-furnishing plants, nuts, beans, berries, yucca and cactus fruits, grass and sunflower seeds, etc., and the flesh of animals, deer, rabbits, lizards, etc.  The canon Indians I have met here seem to be living much as did their ancestors, though not now driven into rock dens.  They are able, erect men, with commanding eyes, which nothing that they wish to see can escape.  They are never in a hurry, have a strikingly measured, deliberate, bearish manner of moving the limbs and turning the head, are capable of enduring weather, thirst, hunger, and over-abundance, and are blessed with stomachs which triumph over everything the wilderness may offer.  Evidently their lives are not bitter.

The largest of the canon animals one is likely to see is the wild sheep, or Rocky Mountain bighorn, a most admirable beast, with limbs that never fail, at home on the most nerve-trying precipices, acquainted with all the springs and passes and broken-down jumpable places in the sheer ribbon cliffs, bounding from crag to crag in easy grace and confidence of strength, his great horns held high above his shoulders, wild red blood beating and hissing through every fiber of him like the wind through a quivering mountain pine.
