The gorge has already been described as narrow at the point where the foamy waters dashed through and expanded into the broad pool, after which they flowed a short way and reunited, to make their next plunge between the mountain walls on their journey to the sea thousands of miles distant.

Looking across this break, the boy could penetrate with his eye for a dozen yards into the upper canyon.

He saw the dripping rocks upon which the angry buck sprang, only to pause and turn back to join his companions below.
A curious thing happened.

Jack was looking in the direction named, when, with startling suddenness, an Indian shot into sight on the furthest rock, beyond which the canyon made a sweeping curve that shut off further view.

His appearance was like the upleaping of a Jack-in-the-box at the touch of the spring, but the explanation was evident: he was making his way down the gorge from above, when his leap from one rock to another brought him thus abruptly into view.
This was interesting of itself, but a still more interesting discovery came with the second glance at him.
