buff, and gray. This painting of the rocks, dividing them into sections, increases their apparent height. In some places these terraced and walled glens along the Colorado have coalesced with those along the Green; that is, the intervening walls are broken down. It is very rarely that a loose rock is seen. The sand is washed off, so that the walls, terraces, and slopes of the glens are all of smooth sandstone.
In the walls themselves curious caves and channels have been carved. In some places there are little stairways up the walls; in others, the walls present what are known as royal arches; and so we wander through glens and among pinnacles and climb the walls from early morn until late in the afternoon.
July 21.--We start this morning on the Colorado. The river is rough, and bad rapids in close succession are found. Two very hard portages are made during the forenoon. After dinner, in running a rapid, the "Emma Dean" is swamped and we are thrown into the river; we cling to the boat, and in the first quiet water below she is righted and bailed out; but three oars are lost in this mishap. The larger boats land above the dangerous place, and we make a portage, which occupies

all the afternoon. We camp at night on the rocks on the left bank, and can scarcely find room to lie down.
July 22.--This morning we continue our journey, though short of oars. There is no timber growing on the walls within our reach and no driftwood along the banks, so we are compelled to go on until something suitable can be found. A mile and three quarters below, we find
a huge pile of driftwood, among which are some cottonwood logs. From these we select one which we think the best, and the men are set at work sawing oars. Our boats are leaking again, from the strains received in the bad rapids yesterday, so after dinner they are turned over and some of the men calk them.
