Across Unknown South America Part 53

Two hundred metres below this rapid the river turned a sharp corner.

There we met one of the most dangerous rapids and whirlpool I have ever seen. It was quite awe-inspiring to look at those vicious waters, the water in the vortex being raised like a wall two or three feet higher than the greatest waves of the rapid by the force with which it revolved.

The entire river--which, as we have seen, was in some places 2,000 m.

wide--was now squeezed through a narrow cut in the hill range, two great arms of water joining directly above that spot. The water was naturally forced through that small opening at an incredible pace. The high vertical rocks at the side of the small channel which was there formed made it extremely difficult to take the canoe down by ropes, especially as the summit of those rocks was much cut up, and we, above, could not keep pace with the canoe as she floated swiftly down the rapid. By fastening together a lot of ropes which we had removed from round the different packages we just managed to make them long enough to undertake the dangerous task.

The hill range, a section of which could be seen at that spot, clearly showed that it was made up of gigantic blocks piled on the top of one another up to a height of 100 ft. At high water the river level must reach--as was evident by the erosion and other signs upon those rocks--nearly to the summit of the range; in fact, when I climbed to the top I found plenty of debris among the rocks, undoubtedly left there by the stream. On the north side the range was made up entirely of gigantic slabs of lava some 15 ft. thick and lying at an angle of 60 with a dip northward. On the south side of the range I had found, instead, great boulders which had evidently travelled there and were much eroded. It can easily be understood that when the water rose it must be held up by the hill range, and form a big lake.

We wasted an entire day trying to find a way to take the canoe over the hills, as we did not dare risk sending her down by water. My men were positively disheartened and on the verge of revolt, as they contended that it was all my fault that I had taken them to a diabolical place like that. I plainly told them that if I gave them such high wages it was because I knew there was a great deal of risk, as I had explained to them at the beginning of the expedition, and I expected them to do some hard work in return.

"But," said the philosopher of the party, "what is the use of money to us if after working hard for months and months we are going to be killed?"

I told them that that was not the moment to argue, but to act; if they followed my orders closely, perhaps we might all escape alive.

Alcides, who was certainly a hard worker, although not always in the right direction, had a nasty accident that day and cut his foot badly on the sharp rocks. He was practically incapacitated for work, as he could only stand on one leg, the other leg being contracted with the really ghastly injury.

This was ill-luck, as our strength combined was not sufficient for the work we had to do, and now the loss of one man--the best of my followers--was an extra trial at the most inopportune moment.

The canoe, too, was in a wretched condition after all the many accidents we had had, and we possessed no more tar, and could spare no more clothes, to stop up the leakages which were now plentiful all over her bottom.

The day of July 31st was thus absolutely lost. I was on the verge of abandoning the canoe there altogether and attempting to get down along the banks of the river on foot--which would have been almost suicidal, as we never could have reached a place of safety.

Night came. At sunset we had the usual concert of mosquitoes, all kinds of insects and frogs, in such innumerable quant.i.ties that the din made by them collectively was so loud as to resemble the sound of an iron foundry or a battle-s.h.i.+p in course of construction, the sounds produced by the millions of nocturnal singers being quite metallic and reproducing exactly the sound of hammers driving rivets into the steel plates of a s.h.i.+p. Whether it was done purposely or accidentally I do not know, but those little water creatures of the Arinos seemed to keep excellent time, their vigour also being most enviable.

On August 1st we had a minimum temperature of 64 F. during the night.

I still saw that it was out of the question to endeavour to take the canoe over the immense boulders and over the hill range. One faint hope, involving very great danger, loomed in my mind. If we could only cross the river just above the fearsome channel we could perhaps on the other side take down the canoe by water. This plan required great smartness, as, had we miscalculated the speed of the river and the rate at which we could travel across that dangerous water, it would surely mean certain death.

I spoke to my men about it. They said they were ready to go. I explained to them that they must paddle their hardest and not give way for a second until we had got diagonally across the fairly still waters only a few yards above the awful channel. Should we by misfortune be dragged into that channel by the current we might as well say good-bye to the world.

When we started on that job we risked everything. My men behaved splendidly that day. They paddled and paddled for all they were worth, to get across the hundred metres or so, and took the best part of half an hour in the formidable current. For a moment, when the canoe was in the centre where the current was strongest and we were making no headway, I saw a bad look-out for us. I urged them on with shouts of "_Rema!

rema!_" (Row! row!) and at last, in a desperate effort, the canoe once more moved forward. It was a relief indeed when men and baggage were safely landed on the opposite side.

All were so exhausted that for a couple of hours it was out of the question to resume work. I occupied that time in taking observations for alt.i.tude and longitude, tortured to death as usual by the innumerable bees and _piums_. (Lat. 8 54'6 S.; long. 58 51' W.)

The temperature in the sun was 107 F. The red and black volcanic rocks radiated such heat that we were nearly stifled in the enclosed basin which was formed by the hill range.

In the afternoon we began with the second part of the dangerous task of endeavouring to take the canoe through the current in a north-easterly direction. The channel in that cut was 200 m. long and only 50 m. wide.

The rock was laminated in layers 6 ft. thick, which had been subsequently baked into a solid ma.s.s. The lower portion, of beautiful black and quite s.h.i.+ny, threw up by contrast the vivid red colour of the upper part.

We had an exciting time when we started the canoe with ropes down that rapid. We ran with bare feet upon the sharp broiling rocks. We could not possibly stand on them with our shoes on. We ran along for all we were worth, in order to prevent the canoe escaping. We climbed up and down great cuts from 10 to 30 ft. high in the rock, never letting go the ropes. Our agility that day was remarkable. Even poor Alcides, whose foot I had wrapped up with a piece of my s.h.i.+rt, was coming along pluckily, regardless of the pain which he certainly suffered. Once or twice, when we remained slightly behind in that awful race, the canoe nearly pulled us into the water from our high point on the rocks some 30 to 50 ft. above.

Those 200 m. of channel seemed miles long to us. Eventually, the canoe was brought out safely at the other end. With bleeding feet and hands we returned once more to our point of departure in order to convey all our baggage upon our backs. After two or three journeys backwards and forwards we were able to proceed a short distance down the river, where we could find a suitable camping-place to rest our weary bones for the night.

On leaving the rapids the river took a direction of 310 b.m. There was a high hill to the east and another, equally high, to the west. The chain of hills seen from the north showed much erosion in the centre, where the rock was exposed underneath. On the south side the upper portion of the hill range consisted of a vertical rocky cliff in strata each 6 ft.

thick.

Another cut, more unpleasant even than ours, had been made by the river in that same range to the north-east of that through which we had taken the canoe. An island of rock rose between those cuts.

A few hundred metres below the mouth of that ugly channel we found an extensive beach, on which we made our camp for the night. The minimum temperature during the night of August 2nd was 64 F.

When we landed the men were proceeding to cut down the foliage on the edge of the forest, so as to be able to hang their hammocks, when they became greatly excited on discovering several nests of _maribondos_ (hornets), graceful cones of a parchment-like material enclosing a number of superposed discs from one to three inches in diameter and about a quarter of an inch apart. Each disc had a perforation in order to let the dwellers in those little homes pa.s.s from one chamber to another from the highest of the cone down to the lowest in the apex.

When we left at 7.30 in the morning and had gone but 1,800 m., the river suddenly described a sharp angle and at that point went through a narrow neck. Afterwards it widened once more to an average breadth of 800 m., which it kept for a distance of 3 kil. in a straight line, the channel being there quite clear of rocks and the water beautifully smooth.

The river was indeed lovely in that part. I had a little more time there to look round at the scenery on either side of us. I noticed that rubber was still to be found, but in small quant.i.ties in that region. Rubber trees were only to be seen every now and then. Looking back to the south and south-west on the range of hills we had left behind, I could see that it extended far to the north-west. The highest part of it, however, seemed to be near the point where we had negotiated the dangerous rapid.

We had gone no more than 9,600 m., when we came to another bad rapid over a barrier of rock across the river from north-east to south-west. A tributary 10 m. wide at the mouth occurred on the right just before this rapid. Beautiful trees of great height, with yellow ball-like blooms, enlivened the scenery as we went along. We had little time to appreciate the beauty of the vegetation--we were too busy with the river. No sooner had we got through one rapid than we came to another alarming one, with a sudden drop of over 6 ft. and enormous volumes of water pouring over it.

This rapid described an arc of a circle, forming an awe-inspiring whirlpool below the actual fall. We had some trouble in finding a place where we could get the canoe through. Eventually, with water up to our necks, we let her gradually down the high step in the middle of the river, we standing with great difficulty on submerged rocks. We had then to make several journeys backwards and forwards to convey the various loads to the canoe after we had brought her to a place of safety, our baggage having been left on rocks in mid-stream. This was extremely risky work, for the current was powerful and the water reached in some places up to our necks. I was anxious for the men who could not swim, as I was afraid any moment they might be washed away, and not only should I lose them but also the valuable instruments, photographic plates, etc., which they were conveying across.

Again that day I had seen since the early morning our friend the little white solitary cloudlet, standing out motionless against the otherwise speckless blue sky. Not only that, but on that particular day I could just perceive, directly under that cloudlet, a faint column of white mist connecting it vertically with the ground. I knew by that sign that we could not be far off a big waterfall; in fact, I could hear a distant rumble which made me suspect that we were much nearer than we supposed.

The river was flowing to 70 b.m. Two other rapids--most violent--were reached within a short distance of each other; then, shortly beyond these obstacles, where the river described a graceful turn, we had before us a great surprise. We heard a loud roar like thunder; it had been getting louder and louder, and grew quite deafening when we turned round the corner. Behold! we had no more scenery upon the horizon before us on the river, but the sky came right down to the water. Great clouds of mist rose up in quick succession in graceful circles. There was an island in the centre of the stream; then to the left of the island the sky again came right down to the water. There a curious effect was to be seen, a high pointed cone of water shooting up skyward with terrific force, then rolling upon itself only to give way to another cone of water succeeding it.

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 hards.h.i.+ps 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.

On the left side of the river also the waterfall made an amphitheatre of rock somewhat smaller than the right fall. Down below, at the foot of this, it formed huge ma.s.ses of white foam, above which profuse spray rose up like a heavy mist. Just beyond was disclosed a diabolical whirlpool, far beyond words to describe, which extended--as white as snow with the amount of foam it carried, twisting and retwisting in a thousand circles on the surface--for over 500 m. from the lower step of the waterfall.

I measured the height of the fall with a string. The exact height of the upper terrace was 6 m. 90 cm.; the height of the lower terrace, 7 m. 73 cm.--or a total height of 14 m. 63 cm.

I also took the differential height with the several aneroids I possessed, and the elevation with the boiling-point thermometers above the fall and below, with a result of 48 ft. for the actual height of the fall.
