to extricate himself from his dilemma, but, if possible, he had to get his own back on Don as well.
He walked back to the control position, and switched on the motor. A slight pressure on the throttle, and the torp began to stir restlessly while a flurry of sand was gouged out of the sea bed by the jet. A little experimenting showed that it was possible to "walk" the machine, though it required continual adjustments of trim to stop it from climbing up to the surface or burying itself in the sand. It was, thought Franklin, going to take him a long time to get home this way, but he could do it if there was no alternative.
He had walked no more than a dozen paces, and had acquired quite
a retinue of astonished fish, when another idea struck him. It seemed too good to be true, but it would do no harm to try. Climbing onto the torpedo and lying in the normal prone position, he adjusted the trim as carefully as he could by moving his weight back and forth. Then he tilted the nose toward the surface, pushed his hands out into the slip stream on either side, and started the motor at quarter speed.
It was hard on his wrists, and his responses had to be almost in stantaneous to check the weaving and bucking of the torpedo. But with a little experimenting, he found he could use his hands for steering, though it was as difficult as riding a bicycle with one's arms crossed. At five knots, the area of his flattened palms was just sufficient to give control over the vehicle.
He wondered if anyone had ever ridden a torp this way before, and felt rather pleased with himself. Experimentally, he pushed the speed up to eight knots, but the pressure on his wrists and forearms was too great and he had to throttle back before he lost control.
There was no reason, Franklin told himself, why he should not now make his original rendezvous, just in case Don was waiting there for him. He would be about five minutes late, but at least it would prove that he could carry out his assignment in the face of obstacles which he was now quite sure were entirely man-made.
Don was nowhere in sight when he arrived, and Franklin guessed what had happened. His unexpected mobility had taken Burley by sur prise, and the warden had lost him in the submarine haze. Well, he could keep on looking. Franklin made one radio call as a matter of principle, but there was no reply from his tutor. "I'm going home!" he shouted to the watery world around him; still there was silence. Don was probably a good quarter of a mile away, conducting an increasingly more anxious search for his lost pupil.
There was no point in remaining below the surface and adding to the difficulties of navigation and control. Franklin took his vehicle up to the top and found that he was less than a thousand yards from the Maintenance Section jetty. By keeping the torp tail heavy and nose up he was able to scorch along on the surface like a speedboat without the slightest trouble, and he was home in five minutes.
As soon as the torpedo had come out of the anticorrosion sprays which were used on all equipment after salt-water dives, Franklin got to work on it. When he pulled off the panel of the control compartment, he discovered that his was a very special model indeed. Without a circuit diagram, it was not possible to tell exactly what the radio-operated relay unit he had located could do, but he did not doubt that it had an interest-
ing repertory. It could certainly cut off the motor, blow or flood the buoyancy tanks, and reverse the rudder and elevator controls. Franklin suspected that compass and depth gauge could also be sabotaged if re quired. Someone had obviously spent a great deal of loving care making this torpedo a suitable steed for overconfident pupils. . . .
He replaced the panel and reported his safe return to the officer on duty. "Visibility's very poor," he said, truthfully enough. "Don and I lost each other out there, so I thought I'd better come in. I guess he'll be along
