Peering downward, the awed and grateful boys saw the black mass suddenly strike the foamy waters and send the spray flying in all directions. It disappeared for a moment and then popped up like a rubber-ball, and went dancing down the current toward the break in the walls which they had visited a brief while before.

Still silent and watching, they observed it dancing up and down with the violence of the stream until its motion was arrested by striking an obstruction, which held it motionless. There it stayed for the remaining minutes spent in peering into the abyss.

Jack and Fred looked up and across the canyon at the same instant. They were directly opposite, and hardly twelve feet apart. The elder took off his hat and called:

"Are you ready?"

"Yes," said Fred, removing his head-gear.

"All together!"

And then they swung their hats and hurrahed with the vim which, all things considered, was justified by events. They were happy and grateful, and neither forgot to thank, with all the fervency of his nature, the One who had delivered them in safety from the very jaws of death. No matter what other dangers might come to them, there could be none narrower or more striking than that through which they had just passed.

"Do you intend to stay on that side of the canyon?" asked Fred.

"I don't know that there is any choice between our places, but if you feel lonely I'll come over to your help."

"I thought you might want to pick up the gun you threw away."
