I stayed looking on a considerable time, highly delighted at such an opportunity of seeing these interesting people in their most characteristic festivals. I was myself a great object of admiration, principally on account of my spectacles, which they saw for the first time and could not at all understand. A hundred bright pairs of eyes were continually directed on me from all sides, and I was doubtless the great subject of conversation. An old man brought me three ripe pine-apples, for which I gave him half-a-dozen small hooks, and he was very well contented.

Senhor L. was conversing with many of the Indians, with whom he was well acquainted, and was arranging with one to go up a branch of the river, several days' journey, to purchase some salsa and farinha for him. I succeeded in buying a beautiful ornamented murucú, the principal insignia of the Tushaúa, or chief. He was very loth to part with it, and I had to give an axe and a large knife, of which he was much in want. I also bought two cigar-holders, about two feet long, in which a gigantic cigar is placed and handed round on these occasions. The next morning, after making our payments for the articles we had purchased, we went to bid our adieus to the chief. A small company who had come from some distance were taking their leave at the same time, going round the great house in Indian file, and speaking in a muttering tone to each head of a family. First came the old men bearing lances and shields of strong wicker-work, then the younger ones with their bows and arrows, and lastly the old and young women carrying their infants and the few household utensils they had brought with them. At these festivals drink alone is provided, in immense quantities, each party bringing a little mandiocca-cake or fish for its consumption, which, while the caxirí lasts, is very little. The paint on their bodies is very durable, for though they never miss washing two or three times a day, it lasts a week or a fortnight before it quite disappears.

Leaving Ananárapicóma, we arrived the same evening at Mandii Paraná, where there was also a malocca, which, owing to the great rise of the river, could only be reached by wading up to the middle through the flooded forest. I accordingly stayed to superintend the making of a fire, which the soaking rain we had had all the afternoon rendered a somewhat difficult matter, while Senhor L. went with an Indian to the house to arrange some "negocio" and obtain fish for supper. We stayed here for the night, and the next morning the Indians came down in a body to the canoe, and made some purchases of fish-hooks, beads, mirrors, cloth for trousers, etc., of Senhor L., to be paid in farinha, fowls, and other articles on our return. I also ordered a small canoe as a specimen, and some sieves and fire-fanners, which I paid for in similar trifles; for these Indians are so accustomed to receive payment beforehand, that without doing so you cannot depend upon their making anything. The next day, the 12th of June, we reached Sâo Jeronymo, situated about a mile below the first and most dangerous of the Falls of the Uaupés.

For the last five days I had been very ill with dysentery and continual pains in the stomach, brought on, I believe, by eating rather incautiously of the fat and delicious fish, the white Pirahiba or Laulau, three or four times consecutively without vegetable food. Here the symptoms became rather aggravated, and though not at all inclined to despond in sickness, yet as I knew this disease to be a very fatal one in tropical climates, and I had no medicines or even proper food of any kind, I certainly did begin to be a little alarmed. The worst of it was that I was continually hungry, but could not eat or drink the smallest possible quantity of anything without pains of the stomach and bowels immediately succeeding, which lasted several hours. The diarrhœa too was continual, with evacuations of slime and blood, which my diet of the last few days, of tapioca-gruel and coffee, seemed rather to have increased.

I remained here most of the day in my maqueira, but in the afternoon some fish were brought in, and finding among them a couple of new species, I set to work figuring them, determined to let no opportunity pass of increasing my collections. This village has no malocca, but a number of small houses; having been founded by the Portuguese before the Independence. It is pleasantly situated on the sloping bank of the river, which is about half a mile wide, with rather high land opposite, and a view up to the narrow channel, where the waters are bounding and foaming and leaping high in the air with the violence of the fall, or more properly rapid.

There was a young Brazilian "negociante" and his wife residing in this village, and as he was also about ascending the river to fetch farinha, we agreed to go together. The next morning we accordingly started, proceeding along the shore to near the fall, where we crossed among boiling foam and whirling eddies, and entered into a small igaripé, where the canoe was entirely unloaded, all the cargo carried along a rugged path through the forest, and the canoe taken round a projecting point, where the violence of the current and the heaving waves of the fall render it impossible for anything but a small empty obá to pass, and even that with great difficulty.

The path terminated at a narrow channel, through which a part of the river in the wet season flows, but which in the summer is completely dry. Were it not for this stream, the passage of the rapids in the wet season would be quite impossible; for though the actual fall of the water is trifling, its violence is inconceivable. The average width of the river may be stated at near three times that of the Thames at London; and it is in the wet season very deep and rapid. At the fall it is enclosed in a narrow sloping rocky gorge, about the width of the middle arch of London Bridge, or even less. I need say no more to prove the impossibility of ascending such a channel. There are immense whirlpools which engulf large canoes. The waters roll like ocean waves, and leap up at intervals, forty or fifty feet into the air, as if great subaqueous explosions were taking place.

Presently the Indians appeared with our canoe, and, assisted by a dozen more who came to help us, pulled it up through the shallows, where the water was less violent. Then came another difficult point; and we plunged again into the forest with half the Indians carrying our cargo, while the remainder went with the canoe. There were several other dangerous places, and two more disembarkations and land carriages, the last for a considerable distance. Above the main fall the river is suddenly widened out into a kind of a lake, filled with rocky islands, among which are a confusion of minor falls and rapids. However, having plenty of Indians to assist us, we passed all these dangers by a little after midday, and reached a malocca, where we stayed for the afternoon repairing the wear and tear of the palm-mats and toldas, and cleaning our canoe and arranging our cargo, ready to start the next morning.

In two days more we reached another village, called Jukeíra Picóma, or Salt Point, where we stayed a day. I was well satisfied to find myself here considerably better, owing, I believe, to my having tried fasting as a last resource: for two days I had only taken a little farinha gruel once in the twenty-four hours. In a day and a half from Jukeíra we reached Jauarité, a village situated just below the caxoeira of the same name, the second great rapid on the Uaupés. Here we had determined to stay some days and then return, as the caxoeira is very dangerous to pass, and above it the river, for many days' journey, is a succession of rapids and strong currents, which render the voyage up at this season in the highest degree tedious and disagreeable. We accordingly disembarked our cargo into a house, or rather shed, near the shore, made for the accommodation of traders, which we cleaned and took possession of, and felt ourselves quite comfortable after the annoyances we had been exposed to in reaching this place. We then walked up to the malocca, to pay a visit to the Tushaúa. This house was a noble building of its kind, being one hundred and fifteen feet long, seventy-five wide, and about twenty-five feet high, the roof and upper timbers being black as jet with the smokes of many years. There were besides about a dozen private cottages, forming a small village. Scattered around were immense numbers of the Pupunha Palm (Guilielma speciosa), the fruit of which forms an important part of the food of these people during the season; it was now just beginning to ripen. The Tushaúa was rather a respectable-looking man, the possessor of a pair of trousers and a shirt, which he puts on in honour of white visitors. Senhor L., however, says he is one of the greatest rogues on the river, and will not trust him, as he does most of the other Indians, with goods beforehand. He rejoices in the name of Calistro, and pleased me much by his benevolent countenance and quiet dignified manner. He is said to be the possessor of great riches in the way of oncas' teeth and feathers, the result of his wars upon the Macús and other tribes of the tributary rivers; but these he will not show to the whites, for fear of being made to sell them. Behind the malocca I was pleased to see a fine broad path, leading into the forest to the several mandiocca rhossas. The next morning early I went with my net to explore it, and found it promise pretty well for insects, considering the season. I was greatly delighted at meeting in it the lovely clear-winged butterfly allied to the Esmeralda, that I had taken so sparingly at Javíta; and I also took a specimen of another of the same genus, quite new to me. A plain-coloured Acrœa, that I had first met with at Jukeíra, was here also very abundant.

In a hollow near a small stream that crossed the path I found growing the singular palm called "Paxiúba barriguda" (the big-bellied paxiuba). It is a fine, tall, rather slender tree, with a head of very elegant curled leaves. At the base of the stem is a conical mass of air-roots, five or six feet high, more or less developed in all the species of this genus. But the peculiar character from which it derives its name is, that the stem at rather more than halfway up swells suddenly out to double its former thickness or more, and after a short distance again contracts, and continues cylindrical to the top. It is only by seeing great numbers of these trees, all with this character more or less palpable, that one can believe it is not an accidental circumstance in the individual tree, instead of being truly characteristic of the species. It is the Iriartea ventricosa of Martius.
