The canoe was almost against the bank, where something of the bewilderment of Ashman seemed to enter the head of Bippo. He spoke to his companions and the three ceased paddling. Ashman had done so a moment before and was scanning the bank with a searching but vain scrutiny.

"You must have been mistaken," he said in a low voice; "they could not have swam the river and they had no other way of crossing."

"We seed 'em--motion dat way," and the native beckoned with his right arm, just as a person would do when signaling another to approach.

"I can't understand it," replied Ashman, with a shake of his head.

His doubts were confirmed, when he recalled that the professor and Jared Long had gone up the bank of the river with the purpose of learning the extent of the rapids. It followed, therefore, that if they had made their way to the other sh.o.r.e, it must have been at a point so far above the angry waters that there was no danger of being caught in the furious current.

He was turning over these troublous thoughts, when Bippo, who was facing the bank they had left, uttered an expression of dismay and extended his arm toward the sh.o.r.e behind them.

Ashman turned his head, and there in the moonlight he saw Professor Grimcke and the New Englander standing on the land and motioning to them to return.

"Yes--dat de way he do--he move arm like _dat_," said Bippo; "we hurry to go to him, den he ain't here--but _dere_."

Ashman could not doubt that the servant believed the extraordinary a.s.sertion he had just made, and such being the case, the startling truth was manifest; they had seen two strangers whom they mistook for their own friends, and these strangers had beckoned them to paddle the canoe to the other sh.o.r.e where they were awaiting them.

If such were the fact--and he did not doubt it--a new mystery confronted him.

Who were the white men and strangers? and why had they disappeared when approached by the canoe and its occupants?

Ashman ordered the servants to turn the craft about and return to the sh.o.r.e they had left with all speed. While doing so, and while Grimcke and Long were doubtless wondering what had got into the heads of the others, the young man wrought himself into a most uncomfortable condition of mind.

He questioned Bippo more particularly as to the appearance and actions of the strangers. It was clear that he, as well as the other two, still believed the couple on the opposite bank were Grimcke and Long; though when reminded that it was impossible that they could have crossed and recrossed the stream in such a brief time, and without any means except that of swimming, they only shook their heads, signifying that, though they could not explain _that_ feature of the strange business, they would not yield their belief.

Ashman asked further, directing his question to each of the natives in turn, whether they saw the parties plainly enough to make sure they were white men. The servants were positive on this point, adding the distracting statement that they were dressed precisely like the two absent members of the little company, and that each carried a rifle as they did.

"Same ones--same ones; don't know how cross riber, but allee same do so," repeated Bippo, with a grin.

By this time the swiftly moving canoe was well on the way to the camp which it had left so abruptly, and, a minute later, Ashman sprang out and grasped the hand of each of his friends in turn.

In a few words he explained the extraordinary incidents of the last half hour, receiving in return the story of the experience of the Professor and his companion. The latter were deeply touched by the loss of Johnston. Danger tends to draw the members of a party closely together, and, despite the peculiar disposition of the sailor, the three felt a deep attachment for him. They would have faced any danger in his behalf, but the time had pa.s.sed for that, and they could only mourn the loss of such a valuable comrade.

"But what about this story that Bippo tells?"

Before a reply could be made, the native approached, with his peculiar grin.

"How you cross riber?--why you come back 'gin? Why you no stay ober dere when we hurry to go to you?"

"Bippo, you are mistaken," replied the Professor, with all the earnestness at his command. "We went up this side of the stream, and have not been on the other side since dark. When we came back and saw that you were not in the camp, we thought you had all been killed."

The native grinned more than ever, and shook his head.

"De Purfes'r funny man--he make laugh." And he walked back to his companions with an unshakeable belief in the story given to Fred Ashman when he dashed in such excitement from the wood.

"Bippo believes what he has told us," said Long, who had studied the fellow closely; "and it follows that he and the others _did_ see a couple of white men."

"I imagined," remarked Grimcke with something like regret in his tones, "that we were the first of our race to reach this spot; but it is hard in these days to find any place on the globe where some white person had not been before us."

"If there are a couple of them over there," said Ashman, scanning the opposite bank, "they ought to be friends; and, after signaling to our servants to cross, it is inexplainable that they should withdraw from sight as they did."

"We can depend on _one_ thing," added the Professor; "we haven't seen the last of them. I would be glad to believe them friends, but their actions are unsatisfactory. I am inclined to think that the cause of their withdrawing was your entrance into the canoe. For some reason they wished to have nothing to do with any of us."

"It may be that since we are suspicious of them," said Fred, "they feel the same toward us, and are unwilling to make our acquaintance until after reconnoiterin' us. h.e.l.loa! what's up now?"

This question was caused by the action of Bippo, who, trembling in every limb, and with the appearance of a person overcome with terror, pointed to the forest behind them.

CHAPTER IX.

A NATIVE HERCULES.

The savages that had shown such pluck in the instances described, now gave another striking proof of their courage.

At the moment the mystified explorers were discussing the strange appearance and actions of the white men, more than twenty of the athletic barbarians issued as stealthily as phantoms from the trail leading from the forest and crouched along the edge of the timber.

Their silence added impressiveness to the singular scene and prevented their movements being observed except by Bippo, who was so terrified that he could only tremble and point at them.

They were partly hidden by the shadow which put out a short distance from the fringe of the wood, but there could be no doubt of their hostile intentions. They a.s.sumed the form of a line, somewhat after the manner of the combatants in the square of the native village. This was to give free play to their arms in flinging their javelins.

The occasion was one in which the fate of the explorers depended upon their promptness and bravery. Anything like timidity or hesitation meant sure destruction, and the whites knew it.

"Into the boat!" commanded Ashman, addressing Bippo and his friends.

The words were like an electric shock to the helpers, who instantly clambered into the canoe and lay flat behind the luggage, where they were safe from the poisoned missiles that would soon be flying through the air.

Those natives, with their crude weapons, were only inc.u.mbrances in a crisis like the present.

The whites exchanged but a word or two and then opened the ball.

A savage, evidently the leader, and one who probably now saw the whites for the first time, had the audacity to step forward a couple of paces, and with a yell of defiance, raised his spear over his head.

Before he could launch the missile Jared Long sent a bullet through him, and then, shifting the muzzle of his Winchester toward the line of dusky figures, he blazed away as fast as he could sight the weapon and pull the trigger.

At the same instant the Professor and Ashman opened, and the bombardment which followed was enough to strike terror to the hearts of a hundred men.

It was more than the savages could stand, but, great as was their panic, most of them hurled one or two javelins apiece at the white men who stood fearlessly erect and combated them. They had come from their village prepared for a fight, and each warrior was provided with several of the poisoned missiles.

Before the explorers had emptied the magazines of their Winchesters not a live foe was left. The affrighted survivors, shrieking with terror, scrambled hastily back among the trees, some of them dragging the dead bodies, so that the spot was freed of the dusky miscreants with as much suddenness as it had been occupied by them.

There were plenty of shots left, and, after the disappearance of the savages, the whites fired into the woods, where they had vanished, not with the expectation of accomplishing anything more than adding to the panic.

When it was sure the wretches were gone, our friends made their preparations for leaving the spot, for nothing was clearer than that such was the wisest step to take.

It will be borne in mind that all the trouble had taken place on the left bank of the Xingu, no savages having been observed on the western bank. The daring of the savages could not be questioned. They had faced death repeatedly, and now, that they had the strongest of all motives--revenge--to prompt them, they were sure to use every means possible to bring about the ruin of the whites and their three native companions.
