Altogether we caught upwards of a hundred turtle. We then moved on to another lake with a sandy shore, where the net was again drawn for the sake of obtaining fish. I had never seen so many and various fish taken together. It would be impossible to describe them. Among them was a beautiful oval-shaped fish, which the natives call acara. There are numerous species, we heard: some of them deposit their eggs in the sand, and hover over them until the young are hatched; but there are others which take still greater care of them, and have a cavity near the gills, in which the male takes up the eggs and carries them there, not only till they are hatched, but actually keeps the young fry in safety within them. When able to swim they go out and take exercise; but on the approach of danger they rush back into their parents’ mouths for protection. This cavity is in the upper part of the bronchial arches. I should scarcely have believed the fact from the report of the natives, had I not actually seen both the eggs and the young fry in their parents’ head. There are several species of fish in the waters of the Amazon which are thus wonderfully supplied with the means of protecting their young.

“You shall now see another way we have of taking fish,” said our friend Pedro.

We paddled off to a still part of the lake. He then poured out of a calabash some coloured liquid.

“And now let us land,” he said, “and while we take our dinner, watch the result.”

The liquid, he told us, was produced from a poisonous liana called tambo. This is cut up into lengths, washed, and soaked in water, which becomes thus impregnated with the juice.

Before dinner was over, as we looked out on the pool we saw the surface covered with fish floating on their sides, with their gills wide open. The canoe then pushed off, and collected them in great numbers. The poison appeared to have suffocated the fish, although only a small quantity had been poured into the water.

We were as successful in shooting birds, monkeys, and other game, as we were in fishing. One of the Indians used his bow in a curious way, which we had not before seen employed. Throwing himself on his back, he placed his feet lifted up above his body against the bow, and drew the string to his head with both his hands. It was surprising what a correct aim he could thus take. He quickly brought down several birds on the wing at a great height. He showed us also that he could shoot up in the air, and make the arrow fall wherever he pleased. Several times it descended within a few inches of his own head or feet, where it stuck quivering in the ground. We dreaded that it might stick into him; but he laughed at our fears, assuring us that there was not the slightest danger, as he had practised the art from his boyhood, and could perform still more difficult feats. Darkness coming on prevented him from exhibiting them. We spent the night on the driest spot we could find on the banks of the lake. Blazing fires were lighted to keep jaguars, pumas, and boas at a distance.

Next morning, loaded with the spoils of the chase, we commenced our voyage homewards. We were passing a dry, thickly-wooded island, when we caught sight of a number of people among the trees, while fires were burning in the centre of several open spots. We asked Pedro what they were about.

“They are my father’s labourers,” he said. “You shall come on shore, and we will see how they are employed.”

We found a number of Indians and a few blacks busily engaged in various ways; some in making gashes in the stems of trees, under each of which they placed a little clay cup or a shell, into which trickled the sap issuing from the wound. This sap we found was of the consistency of cream. And now we saw for the first time the india-rubber with which we had only before been acquainted when using it to rub out our pencil strokes when drawing at school. The trees which were thus treated had a bark and foliage not unlike that of the European ash; but the trunks were of great size, and shot up to an immense height before throwing off their branches. People with large bowls were going about from tree to tree, and emptying the contents of the little cups into them. From thence they were carried to their camp. Here we found large bowls full of the cream-like sap. The labourers were provided with a number of clay moulds of various shapes, though most of them were in the form of round bottles. These moulds were dipped into the liquid, and then hung up to dry. As soon as one layer was dry the mould was again dipped in, and thus coat after coat was put on. Pedro told us it took several days before the coating was considered sufficiently thick. It was then hard and white. This operation being finished, it was passed several times through a thick, black smoke which issued from fires. We found that this smoke was produced by burning the nuts of the inaja and other palm-trees, by which means the dark colour and softness are obtained. The process is now complete; and the moulds being broken, the clay is emptied out, and the rubber is fit for sale.
