Captain Powell and I go out to climb the wall to the east, for we can see dwarf pines above, and it is our purpose to collect the resin which oozes from them, to use in pitching our boats. We take a barometer with us and find that the walls are becoming higher, for now they register an altitude above the river of nearly 1,500 feet.

July 23.--On starting, we come at once to difficult rapids and falls, that in many places are more abrupt than in any of the canyons through which we have passed, and we decide to name this Cataract Canyon. From morning until noon the course of the river is to the west; the scenery is grand, with rapids, and falls below, and walls above, beset with crags and pinnacles. Just at noon we wheel again to the south and go into camp for dinner.

While the cook is preparing it, Bradley, Captain Powell, and I go up into a side canyon that comes in at this point. We enter through a very narrow passage, having to wade along the course of a little stream until a cascade interrupts our progress. Then we climb to the right for a hundred feet until we reach a little shelf, along which we pass, walking with great care, for it is narrow; thus we pass around the fall. Here the gorge widens into a spacious, sky-roofed chamber. In the farther end is a beautiful grove of cottonwoods, and between us and the cotton-woods the little stream widens out into three clear lakelets with bottoms of smooth rock. Beyond the cottonwoods the brook tumbles in a series of white, shining cascades from heights that seem immeasurable. Turning around, we can look through the cleft through which we came and see the river with towering walls beyond. What a chamber for a resting-place is this! hewn from the solid rock, the heavens for a ceiling, cascade fountains within, a grove in the conservatory, clear lakelets for a refreshing bath, and an outlook through the doorway on a raging river, with cliffs and mountains beyond.

Our way after dinner is through a gorge, grand beyond description. The walls are nearly vertical, the river broad and swift, but free from

rocks and falls. From the edge of the water to the brink of the cliffs it is 1,600 to 1,800 feet. At this great depth the river rolls in solemn majesty. The cliffs are reflected from the more quiet river, and we seem to be in the depths of the earth, and yet we can look down into waters that reflect a bottomless abyss. Early in the afternoon we arrive

at the head of more rapids and falls, but, wearied with past work, we determine to rest, so go into camp, and the afternoon and evening are spent by the men in discussing the probabilities of successfully navigating the river below. The barometric records are examined to see what descent we have made since we left the mouth of the Grand, and what descent since we left the Pacific Railroad, and what fall there yet
