Grimcke, Ashman and Long had read aright the meaning of the amazing demonstration and calmly awaited the issue.

Pausing in the very middle of the dusky force, he addressed them in their native tongue, with savage gestures and a fierceness of tones which rendered every word audible amid the roaring tumult.

Only a second or two was required for him to finish his harangue, when he made a final command for them to fall back, emphasized by the swing of his tremendous arms.

No more striking proof could have been given of the sway of this mighty warrior over his vassals, than was shown by their instant obedience to the order, which fell upon them like the bursting of a thunderbolt from the clear summer sky.

They did not scatter and flee, for they had not been directed to do so, but skurried several rods back among the trees, so as to leave the way open for the explorers to pass around the rapids to the calmer waters above.

Ziffak did not remove his eyes from the natives, until he saw that his commands were not only obeyed, but that it was understood by them that the white men were not to be molested.

This extraordinary person had hastened to the other shore, in accordance with his pledge, only to learn from a couple of Aryks whom he met that the main body of warriors had again crossed the Xingu above the rapids, and were gathered in the wood waiting for the whites to walk into the trap set for them.

Had our friends remained where he left them, no danger would have been encountered, but, as we have shown, they moved up stream and came within a hair's-breadth of being wiped from the face of the earth before their powerful ally could interfere.

The breaking morning gave Ziffak his first knowledge of the mistake they had made, and, leaping into his canoe, he drove it across the stream with resistless speed, reaching the spot in the nick of time, and barely doing that, since he was forced to raise his voice while yet on the river, in order to hold the battle in suspense.

Having satisfied himself that everything was adjusted, Ziffak now turned around, and, without the least appearance of agitation on his swarthy countenance, signified that the path was open for them to continue their journey.
