"And Quexo?"

"He's gone, poor fellow!"

"Oh!" Andy gasped, as if something had struck him; but the blow was a mental not a physical injury. "How——"

THE LAST STAND

The explosion, though terrific, had not the desired effect. Ellerton had succeeded in lighting the fuse, and was on his way back, when the natives lowered a rope from the cliffs. No doubt they had observed him on his way to the cave as he rather thoughtlessly showed himself in crossing the base of the projecting spur.

Cunningly two of the savages lowered themselves on to a ledge within twenty feet of the ground, and on Ellerton's return they hurled a stone with unerring aim, bringing him senseless to the ground.
