. 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.

This was Lower Disaster Falls, the first of many similar rapids we
were to see, but this was one of the worst of its kind. The
swift-rushing river found its channel blocked by the canyon wall on
the right side, the cliff running at right angles to the course of the
stream. The river, attacking the limestones, had cut a channel under
the wall, then turned and ran with the wall, emerging about two
hundred feet below. Standing on a rock and holding one end of a
twenty-five foot string we threw a stone attached to the other end
across to the opposite wall. The overhanging wall was within two feet
of the rushing river; a higher stage of water would hide the cut
completely from view. Think what would happen if a boat were carried
against or under that wall! We thought of
