For the twenty-second time since the great wave had washed him from the steamer"s deck and hurled him, choking and sputtering, upon this inhospitable shore, Waldo Emerson saw the sun sinking rapidly toward the western horizon. Suddenly Waldo became conscious from the corner of his eye that something was creeping upon him from behind out of the dark cave before which he had fought. Simultaneously with the realization of it he swung his cudgel in a wicked blow at this new enemy as he turned to meet it. The creature dodged back, and the blow that would have crushed its skull grazed a hairbreadth from its face. Waldo struck no second blow, and the cold sweat sprang to his forehead when he realized how nearly he had come to murdering a young girl. She crouched now in the mouth of the cave, eying him fearfully. Waldo removed his tattered cap, bowing low. "I crave your pardon," he said. "I had no idea that there was a lady here. I am very glad that I did not injure you." But now his attention was required by more pressing affairs -- the cave men were returning to the attack. They carried stones this time, and, while some of them threw the missiles at Waldo, the others attempted to rush his position. It was then that the girl hurried back into the cave, only to reappear a moment later carrying some stone utensils in her arms.
