The boom came to his ears a second time, off to the east, and now distinctly the report of a cannon. He waited a little, watching, and, when the report came a third time, he saw dimly the flash of the gun, but it was too dark for him to see anything of the ship. She was outside the reefs, how far he could not tell, but he knew by the difference in the three reports that she was driving toward the island. It was for him to save the unknown vessel that was to save him, and in the darkness and storm he felt equal to the task. His soul leaped within him. His whole body seemed to expand. He knew what to do, and, quick as lightning, he did it. He ran at full speed through the woods, his lighted lantern swinging on his arm, and twice on the way he heard the boom of the cannon, each time a little nearer. The reports merely made him run faster. Time was precious, and in the moment of utmost need he was not willing to lose a second. He reached the great heap of wood that he had built up on the beach, worked frantically with flint and steel, shielding the shavings at the bottom with his body, and quickly set fire to them. The blaze crackled, leaped and grew. He had built his pyramid so well, and he had selected such inflammable material, that he knew, if the flames once took hold, the wind would fan them so fiercely the rain could not put them out. Higher sprang the blaze, running to the crest of the pyramid, roaring in the wind and then sending out defiant hissing tongues at the rain. The boom of the cannon came once more, and, then by the light of his splendid bonfire, he looked. There was the ship outside the reefs which his great pyramid of flame now enabled her to see. He shouted in his joy, and threw on more wood. If he could only build that pyramid high enough they would see the opening too and make for it. He worked frantically, throwing on driftwood, the accumulation of many years, and the flames biting into every fresh log, roared and leaped higher. The ship ceased to fire her signal guns, and now he saw, with a great surge of joy, that she was beating up in the storm and trying for the opening in the reef, her only chance, the chance that he had given her. He had done his part and he could do no more but feed the fire. As he threw on wood he watched. His pyramid of flame roared and threw out sparks in myriads. The ship, a sloop, was having a desperate struggle with wind and wave, but his beacon was always there, showing her the way, and he never doubted for a moment that she would make the haven. He was sure of it. It was a terrible storm, and there was a fierce sea beating on the reefs, but a master mind was on the sloop, the mind of a great sailor, and that mind, responding to his signal of the fire, the only one that could have been made, was steering the ship straight for the opening in the reef.
