The noise grew more audible.
Suddenly Joe felt a muscular contraction pass over the powerful frame lying close beside him.

It was a convulsive thrill such as passes through a tiger when he is about to spring upon his quarry.
So subtle and strong was its meaning, so clearly did it convey to the lad what was coming, that he felt it himself; save that in his case it was a cold, chill shudder.
Breathless suspense followed.

Then into the open space along the creek glided a tall Indian warrior.

He was knee-deep in the water, where he waded with low, cautious steps.

His garish, befrilled costume seemed familiar to Joe.
