We landed on the island below and talked of camping for the night, as it was getting late; but the island so rocky and inhospitable that we concluded to try the lower part of the rapid.  This had no descent like the upper end; but it was very shallow, and we soon found ourselves on rocks, unable to proceed any farther.  It took an hour of hard labour to work our heavy boats safely to the shore.

We had been hoping for a rest the next day—­Sunday—­but the island was such a disagreeable place to camp that it seemed necessary to cross to the mainland at least.  A coil of strong, pliable wire had been included in our material.  Here was a chance to use it to advantage.  The stream on the left side of the island could be waded, although it was very swift; and we managed to get the wire across and well fastened at both ends.  Elevating the wire above the water with cross-sticks, our tent and camp material were run across on a pulley, and camp was pitched a hundred yards below, on the left shore of the river.

There were fitful showers in the afternoon, and we rested from our labour, obtaining a great deal of comfort from our tent, which was put up here for the third time since leaving Green River City.  Always, when the weather was clear, we slept in the open.

Monday, the 25th, found us at the same camp.  Having concluded that Disaster Falls was an ideal place for a moving picture, we sent the balance of the material across on the pulley and wire, making a picture of the operation; stopping often because it continued to shower.  Between showers we resumed our work and picture making.

The picture was to have been concluded with the operation of lining the boat across.  E.C. stood on the shore about sixty feet away, working with the camera; Jimmy was on the island, paying out the rope; while I waded in the water, holding the bow of the boat as I worked her between the rocks.  Having reached the end of the rope, I coiled it up, advising Jimmy to go up to a safe crossing and join my brother while I proceeded with the boat.  All was going well, and I was nearing the shore, when I found myself suddenly carried off my feet into water beyond my depth, and drifting for the lower end of the rapid.  Meanwhile I was holding to the bow of the boat, and calling lustily to my brother to save me.  At first he did not notice that anything was wrong, as he was looking intently through the finder.  Then he suddenly awoke to the fact that something was amiss, and came running down the boulder-strewn shore, but he could not help me, as we had neglected to leave a rope with him.  Things were beginning to look pretty serious, when the boat stopped against a rock and I found myself once more with solid footing under me.  It was too good a picture to miss; and I found the operator at the machine, turning the crank as I climbed out.

We developed some films and plates that evening, securing some satisfactory results from these tests.  It continued to rain all that night, with intermittent showers next morning.  The rain made little difference to us, for we were in the water much of the following day as he boats were taken along the edge of another unrunnable rapid, a good companion rapid for the one just passed.
