The native who had made the wonderful throw of the javelin stood a moment longer, and then as if satisfied that he could do no more, he turned about and disappeared.

Fortunately, the missile had struck the upper part of the canoe, through which it tore a jagged hole several inches wide, and a short distance above the water. The injury could be easily repaired, and at present required no attention.

The paddles were again called into play, and the prow of the craft gently touched shore.

Having reached the right bank, the explorers had something to think of beside the savages whom they hoped were left behind for good. Two white men were known to be in the neighborhood, and there was warrant for believing they were as hostile as the natives from whom our friends had had such a narrow escape. With their superior intelligence, there was more to be feared from them than from the brave but ignorant savages; but, at the same time, it was to be hoped they might be conciliated, and that, if not, they would fight without the use of the fearful implements used by the savages, who held human life in such light esteem.

On the other hand, the explorers were too sensible to believe they had seen the last of the warriors that had proven their daring and ferocity.

It was decided to leave all the luggage in the canoe which was held so lightly against the bank that it could be shoved into the river at an instant's need. No fire was to be kindled, although the entire party left the boat and advanced to the edge of the wood, beneath whose shelter they seated themselves on the ground.

The night which they had hoped would afford them much needed rest, promised to be most exhausting in its requirements.

It had been the custom of the explorers, when camping on their way to the Matto Grosso, to have at all times a couple of their number on guard, the night being divided into two watches. For the first five hundred miles, after leaving the Amazon, this precaution was mainly to provide against the wild animals, that were always prowling around camp, and often showed a curiosity to make the acquaintance of the sleepers, and especially of their supplies.

The white men held an earnest consultation, while occupied in eating their evening meal or lunch. Had they deemed it prudent to kindle a fire, they would have prepared some fragrant coffee, of which they carried an abundance, though plenty of the little berries were encountered growing wild along the Xingu.

But that much-relished refreshment was now dispensed with, and they ate their fruit and a slight quantity of dried meat in darkness. The fish in the river was an unfailing source of supply, but that species of food also required fire in its preparation, and was therefore out of the question for the time.

Their latitude was about fifteen degrees south, the temperature being so mild that the whites could have got along very well with as scanty raiment as their native helpers, though, as has been intimated, they clung to a civilized costume. They wore broad Panama hats, flannel shirts, with no coats or vests, and strong duck trousers thrust into their bootlegs. Thus attired, they were probably as comfortable as they could be.

A belt around the waist contained a supply of cartridges for their Winchesters and revolvers, besides affording a resting place for the knives, the indispensible Smith & Wesson being carried in the hip pocket, after the usual fashion.

In view of the unusual peril threatening the party, extra precautions were taken against surprise. It was arranged that Quincal and Jared Long should mount guard until midnight, when they would give way to Pedros and the professor. This would leave Bippo and Ashman free from any duty, their turn to come the following night.

Ashman, however, insisted on taking a part which was somewhat original in its nature. He was confident that if the savages found it impracticable to cross the Xingu in sight of the explorers, they would pass down stream and endeavor to do so, at a point where they could not be observed by those in camp.

He meant, therefore, to station himself so as to be able to detect such a movement. With his repeating rifle at command, he was sanguine of defeating the attempt, even though made by a score of enemies.

But for the peculiar contour of the banks on both sides, the whites could have done much better by simply paddling the canoe a quarter of a mile down the river and then hiding under the overhanging vegetation; but it has been explained that the Xingu, when its volume was swelled by rain, had swept the shores with such violence that they were bare for a dozen feet from the water.

Such a movement, therefore, would have to be made in the full light of the moon, and would, therefore, be plainly perceptible from the opposite bank—a fact which rendered the precaution of no avail.

All conceded the wisdom of Ashman's plan. The Professor urged him in case he found himself growing drowsy, to return at once to camp and allow one of his friends to take his place. The young man gave his promise, and, bidding them good-by, he began stealing down the stream, kee............
