Evening was approaching, when the head man of our bearers spoke to Senhor Silva, who instantly called a halt. The black's quick ears had detected sounds in the distance. "He thinks there are elephants out there," said Senhor Silva, pointing ahead. We were then in a thinly-wooded country, and a charge from those monsters would have been dangerous. We saw, however, a clump of trees on one side, behind which Senhor Silva advised that we should take post till we had ascertained the state of the case. The blacks were eager for us to attack them, hoping to enjoy a feast off the huge bodies of any we might kill. As it might expose the young ladies to danger should we do so, even Stanley resolved to let them pass by unmolested. I have not yet mentioned the leader or head man of the bearers. His name, he told Senhor Silva, was Chickango; but Jack and Timbo called him the Chicken. He was an enormous fellow, and ugly even for an African; but there was a good-humoured, contented expression in his countenance, which won our confidence. His costume was a striped shirt, and a pair of almost legless trousers; while on the top of his high head he wore a little battered straw hat, such as seamen manufacture for themselves on board ship--indeed, his whole costume had evidently been that of a seaman, exchanged, probably, for some articles which he had to dispose of. Chickango, signing to us to remain behind the clump of trees, advanced towards the spot where he expected to find the elephants. Suddenly he threw up his arms, and began shouting at the top of his voice. His cries were answered by similar shouts from a distance; and presently, beckoning to us to come on, he hurried towards the spot whence they proceeded. Passing through a belt of wood, we came in sight of an encampment of blacks seated round their fires. There were upwards of one hundred human beings--men, women, and children. A few of the men were dressed in cast-off European garments, with rings round their arms and legs, their woolly heads being mostly uncovered. Chickango advancing, explained, we concluded, who we were; and we received a hearty welcome from the party. The chief, an old man, sat in their centre, attended by his wives. He was distinguished from his companions by an old battered cocked hat, ornamented with beads. He wore, besides, a checked shirt and a regular Scotch kilt, which had somehow or other found its way into his territory. Senhor Silva then explained to us, through Chickango, that he and his party had come from a considerable distance up the country, where they had gone to collect _caoutchouc_, or india-rubber, the packages of which lay piled up near the centre of the camp. They had collected it some distance up the country, where the vines which produce it grow in considerable quantities. In South America it is obtained from a tree; but in Africa from a creeper of great length, with very few leaves growing on it, and those only at its extremity.
