“Well,” said the doctor, “what is it?”

He took the binocular upon hearing the explanation, but after holding it to his eyes for a few moments returned it to Griggs.

“Is it a mistake?” he said.

Griggs laid his cheek to his rifle, and fired again, to stand gazing across the valley for some moments before he replied—

“No, sir; no mistake, and that Indian knows it.”

“You hit one?”

“Yes, and there were three more just appeared, but, as far as I could make out, they have all gone now.”

There was a little more excitement and watching, but nothing was made out for some minutes. Then the doctor, who had seized the glass and been sweeping the opposite side of the valley in search of danger, exclaimed—

“They’ve gone. Look, Bourne.” He passed the glass to the gentleman addressed. “Across the right, there, over the edge of the cliff.”

“Yes, I see; a large party of them cantering away.”
