"Others, panting for breath, with manes erect, and wild eyes full of the keenest suffering, tried to fly from the scene, but the merciless Indians drove them back into the water. A very few, who succeeded in eluding the vigilance of the guards, regained the bank, stumbling at every step, and lay down upon the sand, exhausted with fatigue, every limb paralyzed from the electric shocks received from the eels.

"I never remember receiving a more terrible shock from a Leyden jar than I did from a gymnotus on which I accidentally trod just after it came out of the water."

The astronomic position of Calabozo having been determined, Humboldt and Bonpland resumed their journey to the Orinoco. The Uriticu, with its numerous and ferocious crocodiles, and the Apure, one of the tributaries of the Orinoco, the banks of which are covered with a luxuriant vegetation such as is only met with in the tropics, were successively crossed or descended.

The latter stream is flanked on either side by thick hedges, with openings here and there, through which boars, tigers, and other wild animals, made their way to quench their thirst. When the shades of night shut in the forest, so silent by day, it resounds with the cries of birds and the howling or roaring of beasts of prey, vying with each other as to which shall make the most noise.

While the Uriticu is inhabited by fierce crocodiles, the Apure is the home of a small fish called the "carabito," which attacks bathers with great fury, often biting out large pieces of flesh. It is only four or five inches long, but more formidable than the largest crocodile, and the waters it frequents are carefully avoided by the Indians, in spite of their fondness for bathing, and the relief it affords them, persecuted as they are by ants and mosquitoes.

Our travellers went down the Orinoco as far as the Temi, which is connected by a short portage with the Cano-Pimichino, a tributary of the Rio Negro.

The banks of the Temi, and the adjacent forests, are often inundated, and then the Indians make waterways, two or three feet wide, between the trees. Nothing could be more quaint or imposing than floating amongst the gigantic growths, beneath their green foliage. Sometimes, three or four hundred leagues inland, the traveller comes upon a troop of fresh-water dolphins, spouting up water and compressed air in the manner which has gained for them the name of blowers.

It took four days to transport the canoes from the Tenir to the Cano-Pimichino, as a path had to be cleared with axes.
