That day we were really in great luck. We had the good fortune to find a bacopari tree simply laden with delicious yellow fruit, not unlike unripe cherries, and we absolutely feasted on them.

To show how unpractical my men were, it is sufficient to tell that, unlike any other human beings on the face of the globe when under a fruit-tree, they did not proceed to shake the cherries down by throwing sticks or by climbing up the tree. No, indeed; but they cut down the huge tree, which required about an hour and a half of very hard work. Anyhow, we got the cherries, and that was the principal thing.

We continued our journey over a small rapid with a low hill range spreading from west to east on the left bank. The river here was 300 m. wide. A hill range from 100 to 200 ft. high was also to be seen on the right bank, running parallel with that on the left. Five or six kilometres farther another high range of a gorgeous cobalt-blue colour and extending from south-west to north-east, stood in front of us. The river in that stretch was most beautiful, and was 900 m. wide. A charming little island 300 m. long was reflected in the water, which looked as still as oil in that particular part, although it actually ran swiftly.

Although that scene was of great placidity, we believed there was more danger ahead of us, for we could hear in the distance the loud roar of another rapid or waterfall. Judging by the noise we knew it must be a big one. Soon afterwards we reached the rapid.

We had the greatest difficulty in approaching this, owing to the strong current we encountered in a small channel we followed near the right bank. The rapid was 400 m. wide and 400 m. long, with a drop of from 4 to 5 ft. Although we expected trouble at that spot, we shot the rapid with comparative ease, but we were badly knocked about, and shipped a considerable amount of water in the high waves thrown violently against the rocks. We camped that night near the rapid, having travelled in the day 26 kil. We made our camp in the forest, and we experienced stifling heat, the minimum temperature (August 9th) being 73° F., with heavy rain which came down upon us through the foliage in regular bucketfuls.

We had nothing to eat in the evening. In the morning our breakfast consisted of two sardines each. We went on in a half-hearted way, my men grumbling all the time, and looking out for birds or monkeys. Seven thousand five hundred metres from our camp we came to a waterfall, where we had endless trouble. The principal channel led to 50° b.m., but the river split up into innumerable channels among islands, islets and rocks that formed a regular maze. The river was in that particular spot 1,200 m. wide, and contained great masses of volcanic rock, much fissured, and having great holes in them. This mass of rock extended from north-east to south-west. There were large cracks, where the mass had split, and had subsequently been eroded by the rush of water. The rock had cutting edges everywhere like those of razors. With endless difficulty we had managed to drag the canoe along nearly to the bottom of that dangerous place, when we were suddenly confronted by a drop of 12 ft. with a terrific rush of water over it. It was impossible for us to negotiate that point, for below was a whirlpool absolutely impassable. We had therefore the tiresome work of dragging back the canoe for some 350 m. up the rapid once more, in order that we might find a more suitable channel. To make things more lively for us, a violent thunderstorm broke out, soaking all our baggage but making little difference to us, as we were soaked already. We had spent that entire day in the water, struggling to take the canoe down the rapid and up once more. By eight o'clock at night we were still working, endeavouring to save the canoe.

We had had no lunch, and now had no dinner. My men felt perfectly miserable, and in their speech did not exactly bless the day they had started with me on that expedition. We had worked hard, and had only covered a distance of 7,500 m. in twelve hours. At sunset, while the storm was raging, we beheld a most wonderful effect of light to the west, very much like a gorgeous aurora borealis. The sky, of intense vermilion, was streaked with beautiful radiations of the brightest lemon-yellow, which showed out vividly against the heavy black clouds directly above our heads. The river reflected the red tints, so that we appeared to be working in a river of blood.

As we had nothing to eat, I thought I would spend my time in taking the correct elevation of that place with the boiling-point thermometers. The man X, the humorist of the party, remarked that if I were killed and went to Heaven or some other place, the first thing I should do would be to take the exact elevation with what he called "the little boiling stove" (the hypsometrical apparatus).

We had a minimum temperature of 62° F. during the night of August 10th.

Next morning I sent my men to reconnoitre, in order to see if they could get some edible fruit. As they stayed away a long time I knew they had found something. In fact, they came back quite in a good humour, as they had found some jacoba or jacuba trees, with abundant fruit on them, most delicious to eat.
