At a signal from their chief the whole band of Indians sank, as it seemed, into the ground, melted off the face of the earth, and only the white men and the chief remained.

“I must go forward alone,” whispered Unaco, turning to Paul. “White man knows not how to go on his belly like the serpent.”

“Mahoghany Drake would be inclined to dispute that p’int with ’ee,” returned Bevan. “However, you know best, so we’ll wait till you give us the signal to advance.”

Having directed his white friends to lie down, Unaco divested himself of all superfluous clothing, and glided swiftly but noiselessly towards the robber camp, with nothing but a tomahawk in his hand and a scalping-knife in his girdle. He soon reached the open side of the wooded hollow, guided thereto by Drake’s persistent and evidently distressing cough. Here it became necessary to advance with the utmost caution. Fortunately for the success of his enterprise, all the sentinels that night had been chosen from among the white men. The consequence was that although they were wide awake and on the qui vive, their unpractised senses failed to detect the very slight sounds that Unaco made while gliding slowly—inch by inch, and with many an anxious pause—into the very midst of his foes. It was a trying situation, for instant death would have been the result of discovery.

As if to make matters more difficult for him just then, Drake’s hacking cough ceased, and the Indian could not make out where he lay. Either his malady was departing or he had fallen into a temporary slumber! That the latter was the case became apparent from his suddenly recommencing the cough. This, however, had the effect of exasperating one of the sentinels.

“Can’t you stop that noise?” he muttered, sternly.

“I’m doin’ my best to smother it,” said Drake in a conciliatory tone.

Apparently he had succeeded, for he coughed no more after that. But the fact was that a hand had been gently laid upon his arm.

“So soon!” he thought. “Well done, boys!” But he said never a word, while a pair of lips touched his ear and said, in the Indian tongue—

“Where lies your friend?”
