The NX-1 swung around, always maintaining a slight forward motion and zigzagging constantly to nullify the heat beam. Wells watched the range-finder closely. The octopi ship slanted downwards, the deadly violet ray stabbing from her bow. Slowly the black dot that represented her appeared on the dial, and slowly it dropped towards the crossed lines that showed the perfect firing point.
Keith grasped the torpedo lever. The NX-1's stern was towards her target. Dead silence hung in the control room. The NX-1 swung slightly. The octopi craft appeared directly in the middle of the dial.
Wells pulled back the lever.
The hiss of compressed air sprang from her stern. He had fired two tubes, his whole stock of stern torpedoes. The pair of dreadful weapons leaped out and settled on their course. Keith shot his gaze to the teleview.
The torpedoes missed. Only by feet, but a miss all the same. They raced on past the octopi submarine and, with a tremendous, ear-numbing explosion, burst on the wall of the cavern beyond. Both ships reeled from the shock. Graham swore viciously, but Wells' masklike face showed no slightest change of expression....
A voice rang in Keith's headphones. "Tough, Keith! Better luck next time!" Then the commander winced. He simply could not answer Hemmy Bowman; could not answer that fine, brave voice....
he stern torpedoes were gone. The tubes could not be reloaded, for the paralyzing ray bound the men to the control room. That left them two torpedoes in the bow.
The violet heat ray kept fingering hungrily on their outer hull, and every man knew that the plates were weakening under the steady strain, which was only lessened by the NX-1's constant zigzagging. The control room was very hot. Both ships were now a full mile from the tunnel entrance. Keith plunged the NX-1 down, swung her around, to bring his bow tubes to bear, and zigzagged upwards.
