must be to the river ere we reach the end of the great canyons. The conclusion at which the men arrive seems to be about this: that there are great descents yet to be made, but if they are distributed in rapids and short falls, as they have been heretofore, we shall be able to overcome them; but may be we shall come to a fall in these canyons which we cannot pass, where the walls rise from the water's edge, so that we cannot land, and where the water is so swift that we cannot return. Such places have been found, except that the falls were not so great but that we could run them with safety. How will it be in the future t So they speculate over the serious probabilities in jesting mood.
July 24.--We examine the rapids below. Large rocks have fallen from the walls--great, angular blocks, which have rolled down the talus and are strewn along the channel. We are compelled to make three portages in succession, the distance being less than three fourths of a mile, with a fall of 75 feet. Among these rocks, in chutes, whirlpools, and great waves, with rushing breakers and foam, the water finds its way, still tumbling down. We stop for the night only three fourths of a mile below the last camp. A very hard day's work has been done, and at evening I sit on a rock by the edge of the river and look at the water and listen to its roar. Hours ago deep shadows settled into the canyon, as the sun passed behind the cliffs. Now, doubtless, the sun has gone down, for we can see no glint of light on the crags above. Darkness is coming on; but the waves are rolling with crests of foam so white they seem almost to give a light of their own. Near by, a chute of water strikes the foot of a great block of limestone 50 feet high, and the waters pile up against it and roll back. Where there are sunken rocks the water heaps up in mounds, or even in cones. At a point where rocks come very near the surface, the water forms a chute above, strikes, and is shot up 10 or 15 feet, and piles back in gentle curves, as in a fountain; and on the river tumbles and rolls.
July 25.--Still more rapids and falls to-day. In one, the "Emma Dean" is caught in a whirlpool and set spinning about, and it is with great difficulty we are able to get out of it with only the loss of an oar. At noon another is made; and on we go, running some of the rapids, letting down with lines past others, and making two short portages. We camp on the right bank, hungry and tired.
FROM THE GRAND TO THE LITTLE COLORADO.
July 26.--We run a short distance this morning and go into camp to make oars and repair boats and barometers. The walls of the canyon have been steadily increasing in altitude to this point, and now they are more than 2,000 feet high. In many places they are vertical from the water's edge; in others there is a talus between the river and the foot of the cliff; and they are often broken down by side canyons. It is probable that the river is nearly as low now as it is ever found. High-water mark can be observed 40, 50, 60, or 100 feet above its present stage. Sometimes logs and driftwood are seen wedged into the crevices over-head, where floods have carried them.
About ten o'clock, Powell, Bradley, Howland, Hall, and I start
