But Paul observed also that he always looked eastward--that is, up the stream--and never down it.
Paul and Wyatt were allowed an increasing amount of liberty, but they were held nevertheless within a ring through which they could not break; Paul was shrewd enough to perceive it, and for the present he made no effort, thinking it a wise thing to appear contented with his situation, or at least to be making the best of it.

Braxton Wyatt commended his policy more than once.
On the morning of the seventh day the chief went down to the bank of the river once more, and began to watch its surface attentively and long, always looking up the stream.

Paul and Braxton Wyatt and some of the warriors stood among the trees, not fifty feet away.

They also could see the surface of the river for a long distance, and Paul's eyes followed those of the chief, Red Eagle.
The Ohio was a great yellow river, flowing slowly on in its wide channel, the surface breaking into little waves, that crumpled and broke and rose again.

Paul could see the stream for miles, apparently becoming narrower and narrower, until it ended in a yellow thread under the horizon.
