Something in this exhibition must have affected the girl at the air jet; for Ross soon began to breathe convulsively, then to see more or less distinctly—while his limbs ceased their flapping—and the first thing he saw was the girl standing over him, her face white as the whites of her distended eyes, her lips pressed tightly together, and poised aloft in her hands one of the pump-brakes, ready for another descent upon the head of Foster, who, still and inert, lay by the side of Ross.

As Ross moved and endeavored to rise, she dropped the club, and sank down, crying his name and kissing him. Then she incontinently fainted.

Ross struggled to his feet, and, though still weak and nerveless, found some spun yarn in a locker, with which he tied the unconscious victim's hands behind his back, and lashed his ankles together. Thus secured, he was harmless when he came to his senses, which happened before Ross had revived the girl. But there were no growling threats coming from him now; conquered and bound, his courage changed to fear again, and he complained and prayed for release.

"Not much," said Ross, busy with the girl. "When I get my wind, I'm going to jam you into that tube, like a dead man. I'll release you inside."

When Miss Fleming was again seated on the tank, breathing fresh air from the jet, Ross went to work with the practical methods of a sailor. He first, by a mighty exercise of all his strength, loaded the frightened Foster on to one of the torpedo trucks, face downward; then he wheeled him to the tube, so that his uplifted face could look squarely into it; then he passed a strap of rope around under his shoulders, to which he applied the big end of a ship's handspike, that happened to be aboard; and to the other end of this, as it lay along the back of Foster, he secured the single block of a small tackle—one of the purchases he had used in handling the torpedoes—and when he had secured the double block to an eyebolt in the bow, he steadied the handspike between his knees, hauled on the fall, with no word to the screaming wretch, and launched him, head and shoulders, into the tube.

As his hands, tied behind him, went in, Ross carefully cut one turn of the spun yarn, hauled away, and as his feet disappeared, he cut the bonds on his ankles; then he advised him to shake his hands and feet clear, pulled out the handspike, slammed the breech-door to, and waited.

The protest from within had never ceased; but at last Ross got from the information, interlarded with pleadings for life, that his hands and feet were free.

"All right. Take a good breath, and I'll flood you," called Ross. "When you're outside, swim up." The voice from within ceased.

Ross threw over the lever that admitted water to the tube, opened the forward door, and applied the compressed air. There was a slight jump to the boat's nose, but with the inrush of water as Foster went out, it sank.

However, when Ross closed the forward door, and had expelled this water, it rose again, and he anxiously inspected the depth indicator.
