Virginia was quick to perceive the necessity for haste, while the pirates at the same instant realized the menace of the new danger which confronted them. A score of muskets belched forth their missiles at the fearless girl behind the scant shield of the machine gun. Leaden pellets rained heavily upon her protection, or whizzed threateningly about her head—and then she got the gun into action. At the rate of fifty a minute, a stream of projectiles tore into the bow of the prahu when suddenly a richly garbed Malay in the stern rose to his feet waving a white cloth upon the point of his kris. It was the Rajah Muda Saffir—he had seen the girl’s face and at the sight of it the blood lust in his breast had been supplanted by another. At sight of the emblem of peace Virginia ceased firing. She saw the tall Malay issue a few commands, the oarsmen bent to their work, the prahu came about, making off toward the harbor’s entrance. At the same moment there was a shot from the shore followed by loud yelling, and the girl turned to see her father and von Horn pulling rapidly toward the Ithaca. 2 THE HEAVY CHEST Virginia and Sing were compelled to narrate the adventure of the afternoon a dozen times. The Chinaman was at a loss to understand what had deterred the pirates at the very threshold of victory. Von Horn thought that they had seen the reinforcements embarking from the shore, but Sing explained that that was impossible since the Ithaca had been directly between them and the point at which the returning crew had entered the boats. Virginia was positive that her fusillade had frightened them into a hasty retreat, but again Sing discouraged any such idea when he pointed to the fact that another instant would have carried the prahu close to the Ithaca’s side and out of the machine gun’s radius of action. The old Chinaman was positive that the pirates had some ulterior motive for simulating defeat, and his long years of experience upon pirate infested waters gave weight to his opinion. The weak spot in his argument was his inability to suggest a reasonable motive. And so it was that for a long time they were left to futile conjecture as to the action that had saved them from a bloody encounter with these bloodthirsty sea wolves. For a week the men were busy constructing the new camp, but never again was Virginia left without a sufficient guard for her protection. Von Horn was always needed at the work, for to him had fallen the entire direction of matters of importance that were at all of a practical nature. Professor Maxon wished to watch the building of the houses and the stockade, that he might offer such suggestions as he thought necessary, and again the girl noticed her father’s comparative indifference to her welfare. She had been shocked at his apathy at the time of the pirate attack, and chagrined that it should have been necessary for von Horn to have insisted upon a proper guard being left with her thereafter.
