All were armed with the frightful javelins, a prick from one of which was enough to cause almost instant death.
The whites could not have been caught at greater disadvantage, and Bippo and Pedros were so overcome that they were unable to move.

Long was on the point of opening a fusillade, when Professor Grimcke was struck by the fact that no one of the Aryks offered to harm them.

They chattered like a lot of magpies, and gathering round them made a movement as if to take possession of their boat.
The New Englander would have showed fight, had not his companion said in a low tone: "They are friendly! They mean to do us no harm!" Such was the astounding truth, and it was easily explained.

Ziffak on his way up the Xingu with his new friends had warned the Aryks that they must do the whites no harm: they were on their way at that time to the Murhapa village as friends, and the head chieftain told his allies that any further hostility would be visited with the punishment of death.
The Aryks were not likely to forget such a notice.

They had seen the boat approaching; and, being totally unsuspicious of what had occurred during the earlier part of the evening, were anxious to manifest their good will by carrying the canoe around the rapids.
Jared Long could hardly credit the truth, and held himself ready for a desperate fight; but, when the boat was lifted upon the shoulders of a half dozen stalwart warriors who started down the shore with it, he smiled grimly and admitted that the Professor was right.
The load was quite burdensome, but the carriers stepped off, highly pleased with the privilege, while the rest of their party straggled after them, the whites and their servants bringing up the rear.
Bippo and Pedros were not quite able to comprehend the extraordinary condition of affairs, and kept close to the heels of their masters like a couple of frightened dogs.
At the base of the rapids, the Aryks set down the boat, with great care, saluted in their rude way, and turning about, disappeared in the forest from which they had emerged.
"_If they only knew_," said Long when they were drifting down stream once more.
"But they _don't_," replied the Professor, "and yet they will learn the truth before long." The boat was allowed to drift a half mile further, when, convinced they had gone far enough, they ran into land, disembarked and carried it in among the trees, where it was out of the sight of any one passing up or down the Xingu.
