sound for several minutes. He had presumed that the others were too interested in what was going on down in the cold, dank dungeon to be disturbed by sounds from the upper world. The sound had a rumbling vibration, the rumble grew louder and louder, and suddenly there was an ear-splitting crash. Dust and chips flew from the walls. "The giants!" Lucretia screamed in wild terror. "They are bowling again." As one, everybody turned and began a pell-mell race for the stairs, until there was only the chained man left. And hard at their heels came another of the ear-splitting crashes. More chips flew, and now tiny streamers of water leaped from cracks which appeared in the stone. Again there was the roar, another crash, and Jenkins moaned in pain as a large chunk of rock struck his side and tore the flesh. He strained against the steel chains which bound him until he thought his blood would burst the bounds of his veins. He pulled again and again and until he could strain no more, until he could only fall limply against his prison-links. His mind was fevered and his thoughts jumbled. He had to escape somehow. Again there was heard that terrorizing crash. He gasped, and turned his head aside, as a torrent of water poured from a fissure in the rock close to his head and shot into his face. He turned his head and felt the metal tear from the wall. His head was free. Like a madman, Jenkins tried again to loose himself. This time he succeeded. And where the chains pulled free, water dribbled from that spot. With a desperate intensity, Jenkins made a superhuman effort and pulled at the chains binding his wrists. The chains came apart, tearing the flesh and leaving raw wounds. Wincing at the pain, he placed his fingers behind his neck and felt of the steel. After a few seconds of probing, he twisted at the nut, which separated from the bolt with a single easy twist. He did the same with the chain binding his ankles—and Jenkins was free! The last length of chain fell into the water, which by now had formed a foot-deep puddle on the floor, and splashed loudly, as Jenkins raced against a new danger. Whatever was causing those crashing sounds was also weakening the foundations of the castle. Water was beginning to pour in a perfect torrent from many cracks. The stairs to the floor above was but twenty feet from where he had been chained, but even in that short distance the water rose another foot.
