on the bottom of the upturned boat, and by catching hold of the opposite gunwale, and throwing ourselves back, we brought her right-side up.  Then we two climbed in, an operation requiring nice calculation, for she rolled so much with the load of water that her tendency was to turn over again on slight provocation.  We bailed with our hats rapidly.  There was need for expeditious work, for we could not tell what might be around the corner.  Presently enough water was out to steady the boat, and we then helped Powell and Jones to get in.  Our oars had fortunately remained in the rowlocks, and grasping them, without waiting to haul in the hundred feet of line trailing in the current, we made for the left wall, where I managed to leap out on a shelf and catch the rope over a projection, before the Canonita, unharmed, dashed up to the spot; her only mishap was the loss of a rowlock and two oars.

Starting once more on the swift current, we found rapids sometimes so situated that it was difficult to make a landing for examination.  At one of these places, towards evening, a good deal of time was spent working down to the head of an ugly looking spot which could not be fairly seen.  An enormous rock lay in the very middle at the head of the descent.  There was no landing-place till very near the plunge, and in dropping down when we came to the point where it was planned that I should jump out upon a projecting flat rock, a sudden lurch of the boat due to what Stanton afterwards called fountains, and we termed boils, caused me, instead of landing on the rock, to disappear in the rushing waters.  The current catching the boat, she began to move rapidly stern foremost toward the fall.  Powell and Jones jumped out on rocks as they shot past, hoping to catch the line, but they could not reach it, and Jones had all he could do to get ashore.  Meanwhile I had come to the surface, and going to the boat by means of the line which I still held, I fairly tumbled on board.  Hillers handed me one of my oars which had come loose, and we were ready to take the fall, now close at hand, albeit we were stern first.  As we sped down, the tide carried us far up on the huge rock, whose shelving surface sank upstream below the surging torrent, and at the same moment turned our bow towards the left-hand bank.  Perceiving this advantage we pulled with all our strength and shot across the very head of the rapid, running in behind a large rock on the brink, where the boat lodged till I was able to leap ashore, or rather to another rock where there was a footing, and make fast the line.  It was a close shave.  The Canonita, forewarned, was able to let down to this place, from whence we made a portage to the bottom the next morning.  When once started again, we found ourselves in a very narrow gorge, where for four or five miles it was impossible to stop on account of the swift current which swept the boats along like chaff before a gale, swinging them from one side to the other, and often turning them round
