The reflections in the evening sky lighted up the vast rift for a while, and Bart forgot his hunger in the contemplation of this strange freak of nature, of a river running below in a channel whose walls were perfectly perpendicular and against which in places the rapid stream seemed to beat and eddy and swirl, while in other parts there were long stretches of pebbly and rocky shore. For as far as Bart could judge, the walls seemed to be about four hundred feet apart, though in the fading evening light it was hard to tell anything for certain.

A more stupendous work of nature had never met Bart’s eye, and his first thoughts were natural enough— How should he manage to get to the top of that flat mountain?—How should he be able to lower himself down into the mysterious shades of that vast canyon, and wander amongst the wonders that must for certain be hidden there?

Just then the Beaver spoke. He had evidently been taking lessons from the interpreter, as, smiling loftily and half in pity at the eagerness of men who could care for such a trifle as white ore when they had horses and rifles, he pointed up at the perpendicular face of the mountain and then downward at the wall of the canyon, and said:—

“Silver—silver. Beaver give his brother. Medicine-man.”

“He means there is silver here, sir, and he gives it to you,” said Bart eagerly.

“Yes. Give. Silver,” said the chief, nodding his head, and holding out his hand, which the Doctor grasped, Bart doing the same by the other.

“I am very grateful,” said the Doctor at last, while his eyes kept wandering about, “but I see none.”

“Silver—silver,” said the chief again, as he looked up and then down, ending by addressing some words in the Indian dialect to the interpreter, who pointed in the direction of the camp.

“The Beaver-with-Sharp-Teeth says, let us eat,” he said.

This brought back Bart’s hunger so vividly to his recollection that he laughed merrily and turned to go.
