The limestone of this canyon is often polished, and makes a beautiful marble. Sometimes the rocks are of many colors--white, gray, pink, and purple, with saffron tints. It is with very great labor that we make progress, meeting with many obstructions, running rapids, letting down our boats with lines from rock to rock, and sometimes carrying boats and cargoes around bad places. We camp at night, just after a hard portage, under an overhanging wall, glad to find shelter from the rain. We have to search for some time to find a few sticks of driftwood, just sufficient to boil a cup of coffee. The water sweeps rapidly in this elbow of river, and has cut its way under the rock, excavating a vast half-circular chamber, which, if utilized for a theater, would give sitting to 50,000 people. Objection might be raised against it, however, for at high water the floor is covered with a raging flood. August 9.--And now the scenery is on a grand scale. The walls of the canyon, 2,500 feet high, are of marble, of many beautiful colors, often polished below by the waves, and sometimes far up the sides, where showers have washed the sands over the cliffs. At one place I 238 8 CANYONS OF THE COLORADO. have a walk for more than a mile on a marble pavement, all polished and fretted with strange devices and embossed in a thousand fantastic patterns. Through a cleft in the wall the sun shines on this pavement and it gleams in iridescent beauty. I pass up into the cleft. It is very narrow, with a succession of pools standing at higher levels as I go back. The water in these pools is clear and cool, coming down from springs. Then I return to the pavement, which is but a terrace or bench, over which the river runs at its flood, but left bare at present. Along the pavement in many places are basins of clear water, in strange contrast to the red mud of the river. At length I come to the end of this marble terrace and take again to the boat. Riding down a short distance, a beautiful view is presented. The river turns sharply to the east and seems inclosed by a wall set with a million brilliant gems. What can it mean? Every eye is engaged, every one wonders. On coming nearer we find fountains bursting from the rock high overhead, and the spray in the sunshine forms the gems which bedeck the wall. The rocks below the fountain are covered with mosses and ferns and many beautiful flowering plants. We name it Vasey's Paradise, in honor of the botanist who traveled with us last year.
