Frank forgot everything except the business in hand as he set eyes, mind and nerve upon reaching the burning motor boat in time to be of some practical service. He was near enough now to pretty well grasp the situation. The launch had been going at a high rate of speed, but the expert young engineer set the lever another notch forward, and sent the craft slipping through the water like a dolphin. The man in charge of the burning boat, Frank saw, had a pan with a handle. He was dipping this into the water and throwing its contents against the blazing after-part of the boat. Some gasoline or other inflammable substance, however, seemed to burn all the more fiercely for this deluge, and the man had to shrink farther and farther away as the flames encroached upon him. A portly lady was shrieking constantly and waving her arms in a state of terror. It was all that a younger woman, the other passenger, could do to hold her in her seat and restrain her from jumping overboard. Frank had just a passing glance for the other actor in the scene. This was the fellow he had seen leap overboard when the boat blew up. He was somewhat older than Frank, and having cast adrift a box, the only loose article aboard that would serve to act as a float, he had drifted safely out of reach of the flames. “He’s a coward, besides being a cad,” involuntarily flashed through Frank’s mind. Then he made the launch swerve, and shouted to the occupants of the motor boat: “All ready!” Frank, with his experience of the past, calculated so nicely that the launch came alongside the burning motor boat at precisely the right angle to allow the man in charge of the latter craft to grapple with a boat-hook. “Quick, Mrs. Carrington,” he spoke to the older lady, “get aboard the launch as fast as you can.” The woman’s girl companion helped her get to her feet, but she pitched about so that but for a clever movement on the part of Frank she would have gone into the water. “Oh, dear! oh, dear!” she screamed, but with the aid of the younger woman Frank managed to get her into the launch, where she dropped in a heap and went into hysterics. Her companion got aboard more quietly. “You are just in time,” gasped the man in charge of the motor boat. “Don’t risk the flames, but pull away.” “Yes, there is nothing to be done in the way of putting out the fire,” said Frank. The man he spoke to was both worried and in pain. His face and hands were blistered from his efforts to shield his passengers from the fire. Just then a howl rang out. It proceeded from the fellow thirty feet away, bobbing up and down on the empty box. This brought the older woman to her senses. “It is Peter!” she screamed. “Oh, save Peter!”
