My men would not camp that night near the rapid, which they said was the devil's home, so during the night we went 2 kil. down the stream, where, simply worn out, we made our camp. We never could get any fish from the stream now. We had gone only 6,000 m. that day. I reckoned that, travelling at that rate, I should perhaps reach my goal, Manaos, in five or six years' time—and all the provisions I had left for seven men, all counted, were now eight tins of sardines.

We had a minimum temperature of 64° F. on the night of August 11th.

We had halted just above another big and beautiful waterfall, 20 ft. high, and of immense width. The great rush of water curled over a gigantic dome of volcanic rock with many big holes and fissures. The waterfall was followed by a ghastly rapid 500 m. long. It was impossible to go over the fall, and the only way left us—a most dangerous one—was to let the canoe down a small channel 50 to 80 m. wide, cut among the vertical rocks on the right side of the waterfall. The water in the channel flowed in steeply sloping cascades. The channel twisted round abruptly in two or three places, and in one spot went through a rocky neck 35 m. wide, where the force of the current was so great that I was really perplexed as to how we could take the canoe down without getting her smashed to atoms.

Providence came to my help again. In looking round I discovered an ancient channel, now almost dry and strewn with innumerable rocks, by which it might be possible to take the canoe overland until we could find a smooth place in the water below the rapid. On further exploring that channel, as I was quick enough in noticing its possibilities, I found at the end of it what the Brazilians call a recanto—that is to say, a backwater which the river had there formed, and which would be a great help to us in floating the canoe once more.

This plan involved a great deal of hard work, as not only had we to shift many large rocks out of their position, but we had to construct a railway with felled trees and rollers upon them. We could not get perfectly horizontal rails, so that the effort of moving the canoe along inch by inch with levers was trying, especially as we had had insufficient food for many days and our strength was fast failing.

To make matters worse, Alcides that day broke out in revolt. He had, like many ignorant people, the misfortune of believing that he knew everything better than anybody else. I had given him instructions to place the rails and rollers in a certain position, so that the canoe could be shifted over some unpleasant rocks. He, however, insisted on placing the rollers in the wrong place and on using the levers in the wrong spots, so that they not only did not act helpfully, but actually had the contrary effect on the canoe from that which we wanted to obtain. I remonstrated, and showed the men once more how to do it. They agreed with me, except Alcides, who became enraged to such an extent that his eyes bulged out of their orbits in his fury. He brandished one of the big levers in the air, and, shouting at the top of his voice, proceeded to give a long harangue stating that Araguary—his native town—produced greater men than England or any other country, and inciting the other men to open revolt against me.

This was a serious affair and most unexpected, as so far I had counted on Alcides to stand by me, no matter what happened. The other men were undecided. Although they were always ready to revolt, they had more confidence in the brain of an Englishman than in that of an Araguary man. Alcides suggested that they should take possession of the canoe and everything, and that I should be left on the rocks. He shouted to the men to take the canoe along, and he himself pushed with all his might, the canoe not budging the tenth part of an inch.

I sat down on a rock. I merely said that the canoe would not move until I wished it to move. This statement I made because I saw that in their stupidity they had placed some pieces of wood under the canoe which acted as wedges instead of rollers; one piece in particular—a roller which had split in two—could not possibly move along the rough wooden rails. The men pushed and worked with all their might for over three hours, the canoe remaining still like a solid rock. At last they came to me and asked me to show them how to move it. I placed the rollers where they would be effective, removing the wedges which were impeding her journey, and with very little effort the canoe moved along.

With wild yells of excitement the men proclaimed this a miracle, always excepting Alcides, who, with a fierce expression on his face, stood now on one side, fondling his rifle. The other men chaffed him, and even insulted him, saying that he had made them struggle for nothing, as he did not know what he was about. When the rails and the rollers were placed right the canoe slid along the distance which remained to be covered, and eventually glided gracefully once more into the water.
