They strode directly onward, and swung across the open space, swerving
enough to one side to avoid the struggling lines, and moving on until
they reached the fringe of spectators beyond. There they could no
longer be identified, and probably took their places among those who
were enjoying the cruel spectacle.

Ashman waited a brief while beside the path, fearful that other natives
might be coming; but, when the minutes passed without their appearance,
he resumed picking his way back, and quickly stood erect in the narrow
opening, which he felt had been followed too far from the Xingu.

There was no reason to suspect that any of the natives knew of the
presence of the mysterious strangers so near them, but since they
seemed to have a remarkable disposition to be on the move, our friends
felt it would not be safe to relax their caution for a single instant.

While they did not apprehend a direct pursuit, there was a probability
that some parties might be moving along the trail behind them, while
they had seen enough to convince them of the danger from the front.
Ashman, therefore, whispered to his companion to keep special guard
against an approach from the rear, while he would be equally alert in
guarding the front.

The two kept so near that they could have reached each other by simply
extending the hand.

They had no more than fairly started on their withdrawal from the spot,
when Johnston touched the arm of his friend, who instantly halted to
learn the cause.
