The most laborious part of the journey now presented itself, which consisted in the great exertions, which were necessary in order to pass the flats and quicksands, which seemed to multiply as they ascended the river, and which obliged the natives to strip and get into the water, to drag the boats over the shallows by main force. Although the natives had now ascertained beyond all further doubt, that Barraconda was not the end of the world, yet, one part of their story was fully verified, which was that relating to the enormous animals, with which these desolate regions were tenanted. To the present travellers, they appeared far more formidable than to their predecessors, for the very elephants that had fled precipitately before the crew of Jobson, struck the greatest terror into the party of Stibbs; for one of them showed such a determined disposition to exhibit the extent of his strength, that he turned suddenly upon the crew, and in a very short time put the whole of them to flight. So little did they show any symptoms of fear for the crew, that they were frequently seen crossing the river in bands, at a very short distance from the boats, throwing up the water with their trunks in every direction, and raising such an emotion in the water, as to make the boats rock about, to the great alarm of the crews, and particularly the natives, who now began to wish, that they had not been seduced by the potency of the spirituous liquid, to venture into a region, where death presented itself to them, in the strict embrace of an elephant's trunk, or bored to death by the teeth of the river horse. In regard to the latter animal, the danger which they incurred, was more imminent than with the elephants, but this did not arise from the greater ferocity or savageness of the animal, for the river horse moves in general in a sluggish and harmless manner; but in the shallow places of the river, the horses were seen walking at the bottom, and the space between them and the boat so small, that the keel often came into collision with the back of the animal, who, incensed at the affront offered to him, would be apt to strike a hole through the boat with his huge teeth, and thereby endanger its sinking. It was evident to the commander of the expedition, that the courage of his native crew was almost paralyzed, when they had to contend with any of these formidable creatures, although he had no reason to complain of their exertions, in dragging the boats over the flats and shallows, which appeared to abound in every part of the river.
