But his foe gave him no chance. Crazy with pain and anger, it swept up and nipped his dive for the bottom with a fluke-blow that tumbled the torpoon over and dazed its pilot. Before he could get straightened out it was on him again, catching him up into a wild whirlpool, butting the shell and flashing round to get its flukes into position. With a wrench, Ken jammed the rudder over, shoved his accelerator flat, and got free just as the tail thrashed down. He was breathing hard and sweating as he banked around—to see once more the whale, its wicked jaws wide open, charging directly at him.

For a moment he was unable to move. Such a mode of attack was totally unexpected, and the sight held him fascinated. He could see the very wrinkles of the monster's skin as it rushed in, with shadowy flukes thrusting behind; could see the lines of dagger-like teeth, the cavernous maw and gullet. And then all vision was blotted out as the jaws closed around the torpoon's nose.

Ken did not wait for those jaws to crunch shut. He gripped the nitro-shell gun's trigger and squeezed it back.

The weapon hissed, flung its shell. He reversed his engines to try and tear free. Seconds dragged by with no result. Then he felt a mighty jolt; his harness broke; and he was pitched into the torp's engine controls.

That was all he knew, save for a vague feeling of falling, falling over and over, which was ended when a second bone-shaking shock brought complete oblivion....


It was darkness that met his eyes when they opened, the eery darkness of the floor of the Polar Sea.

Darkness! Half-conscious as he was, he started in surprise. He looked for the torp's shaded control board-lights, but could not find them. Bewildered, he wondered what had happened, and then remembered the whale. In its flurry it had smashed him down.

Pain was thumping his forehead where he had struck the control levers; with a groan he twisted his body around and felt for his hand-flash. At any rate, there was no water inside the body compartment. The seams had resisted the blow. But why were there no lights?
