First peering out to make sure no soldiers were attempting the passage, Koolau started back on the run for the caves. All the time the shells were moaning, whining, screaming by, and the valley was rumbling and reverberating with the explosions. As he came in sight of the caves, he saw the two idiots cavorting about, clutching each other's hands with their stumps of fingers. Even as he ran, Koolau saw a spout of black smoke rise from the ground, near to the idiots. They were flung apart bodily by the explosion. One lay motionless, but the other was dragging himself by his hands toward the cave. His legs trailed out helplessly behind him, while the blood was pouring from his body. He seemed bathed in blood, and as he crawled he cried like a little dog. The rest of the lepers, with the exception of Kapahei, had fled into the caves. "Seventeen," said Kapahei. "Eighteen," he added. This last shell had fairly entered into one of the caves. The explosion caused the caves to empty. But from the particular cave no one emerged. Koolau crept in through the pungent, acrid smoke. Four bodies, frightfully mangled, lay about. One of them was the sightless woman whose tears till now had never ceased. Outside, Koolau found his people in a panic and already beginning to climb the goat-trail that led out of the gorge and on among the jumbled heights and chasms. The wounded idiot, whining feebly and dragging himself along on the ground by his hands, was trying to follow. But at the first pitch of the wall his helplessness overcame him and he fell back. "It would be better to kill him," said Koolau to Kapahei, who still sat in the same place. "Twenty-two," Kapahei answered. "Yes, it would be a wise thing to kill him. Twenty-three--twenty-four." The idiot whined sharply when he saw the rifle levelled at him. Koolau hesitated, then lowered the gun. "It is a hard thing to do," he said. "You are a fool, twenty-six, twenty-seven," said Kapahei. "Let me show you." He arose, and with a heavy fragment of rock in his hand, approached the wounded thing. As he lifted his arm to strike, a shell burst full upon him, relieving him of the necessity of the act and at the same time putting an end to his count.
