Having captured one of the invaders, seeing the other falling back, and fearing to risk further the devastating fire of the terrifying weapon in the hand of their single antagonist, the Oparians hesitated.

Romero passed through the inner wall, turned and ran swiftly to the outer and a moment later had joined his companions upon the plain.

"Where is Colt?" demanded Zveri.

"They knocked him out with a club and captured him," said Romero. "He is probably dead by this time."

"And you deserted him?" asked Zveri.

The Mexican turned upon his chief in fury. "You ask me that?" he demanded. "You turned pale and ran even before you saw the enemy. If you fellows had backed us up Colt might not have been lost, but to let us go in there alone the two of us didn't have a Chinaman's chance with that bunch of wild men. And you accuse me of cowardice?"

"I didn't do anything of the kind," said Zveri sullenly. "I never said you were a coward."

"You meant to imply it though," snapped Romero, "but let me tell you, Zveri, that you can't get away with that with me or anyone else who has been to Opar with you."

From behind the walls rose a savage cry of victory; and while it still rumbled through the tarnished halls of Opar, Zveri turned dejectedly away from the city. "It's no use," he said. "I can't capture Opar alone. We are returning to camp."

The little priests, swarming over Colt, stripped him of his weapons and secured his hands behind his back. He was still unconscious, and so they lifted him to the shoulder of one of their fellows and bore him away into the interior of the temple.
