My men were terrified when they suddenly realized the danger which was only a few hundred metres in front of us. There was a mighty waterfall. When my men got excited it was generally troublesome, because they always disagreed and started quarrelling and insulting one another. Some of them wanted to land at once, for fear of being dragged down the fall. Alcides—who wanted to show his bravery on all occasions—said there was no danger at all and we could go in the canoe right as far as the edge of the fall. The others naturally got somewhat scared at so foolhardy a project. Personally I did not like to say a word in the matter, for fear they should think that I was afraid. I saw with some concern that Alcides—whose mind, I believe, was not quite right owing to the hardships we had endured of late—was steering us right for the centre of the waterfall. I told him that it would be preferable to land on the edge of the waterfall rather than go over it, as it was a little too high for the canoe to tumble over. I calculated the height of the fall from 40 to 50 ft., and I was not far wrong, for when I took accurate measurements I found the actual height was 48 ft.
We were beginning to drift very speedily with the current, when Alcides, realizing the danger, steered us toward the right bank. The men paddled for their lives so as to land as quickly as possible, as we were now less than a hundred metres from the portentous jump. The current was terrific, and the canoe was floating sideways nearer and nearer the awful chasm. The coast line on the right, was almost vertical, and there was no place where we could hold on to anything and land. So down floated the canoe, my men horror-stricken. Once or twice they were able to seize a creeping vine hanging down the steep bank, endeavouring to stop the canoe's headlong career. But the creepers gave way and crashed down upon us, nearly turning over the canoe at the moment just before they snapped.
So down, down we went, until we were now only a few metres from the fatal drop, and I saw no way of arresting the canoe.
"Estamos perdidos!" (We are lost!) shouted the men.
"Not yet! not yet!" I exclaimed, as I perceived two rocks just sticking out of the water. "Make for the rocks!" I shouted to Alcides, and just as we shaved past them I jumped quickly on one of the rocks, holding the canoe, while two of the men also jumped out quickly and held fast to the boat—just in time. We were only 10 or 15 m. from the place where the water curled over and rolled down the fall.
There was no time for arguing or scolding. Upon those rocks my men, who were fond of talking, started a brisk war of words, saying that they would never continue the journey if Alcides were allowed to steer again. Alcides, on the other hand, whose only aim in life was to fight everybody and everything, invited all the other men to a duel with their rifles. I told them they could have the duel after we had finished the journey and not before. We must take the ropes, climb up to the top of the bank, and, first of all, we must tow the canoe back to a place of safety.
After a great deal of shouting, angry words and oaths, absolutely deadened by the thundering roar of the waterfall, they took out the ropes and eventually towed the canoe back. As soon as that was done I went with my camera to gaze at the beautiful sight and photograph it from different points—a job which was not easy, as the waterfall was so encased between vertical rocky walls (foliated in horizontal strata, which varied in thickness from a quarter of an inch to one foot) that it was impossible to get far enough back to obtain a full view of it.
That fall, called the August Fall, was indeed a grand sight. As I have already said, it was divided into two separate falls, between which was an island with a great spur of rock forming a wall between the two cascades. The water flowed over that wall in graceful steps. The fall on the right side of which I stood was in two immense horseshoe-shaped terraces. The continuation of those terraces on each side of the great flow of water formed tiers of red and black volcanic rock lying in horizontal strata so regular as to be not unlike a gigantic Etruscan amphitheatre. The upper tier of the fall on the right formed an arc not less than 300 m. in periphery. The lower crescent formed an arc 400 m. in length.
Upon this lower terrace the rebounding waters were thrown up with great force into the air—the spray forming numerous rainbows in the sun—only to drop down once more in most contorted, diabolical curves, boiling and roaring in their endeavour to force their way through that positive inferno.
As the water came down in great volumes over those two crescents it met once more in the centre in a mighty clash, being flung up at a tremendous height in the air. I do not know that I have ever seen such a fearsome sight, or that I have ever seen water rush with such force anywhere before. It seemed a pity that there was no one to harness that waterfall and use the enormous power it could generate.
