But what good was all his wood training in this huge hulk of shining metal? No chance for camouflage, no chance to dive into a creek and swim away so that your spoor could be lost in the swirling water.

And then Joe smiled and began to run softly. He had a place to hide if he could make it. The quick pat of hurrying steps stopped him short and his quick mind hurled his body to the side of the passage and asprawl on the floor where the lights cast a shadow.

It was Paul Burnet hurrying up the passage, the light glinting on the butt of the automatic belted at his waist. Only for an instant did Burnet hesitate, then he ran on. His voice drifted back softly:

"I'm giving you another chance. We're even now, Joe."

Joe rose to his feet and hurried on to the power room. Joe halted, breathing deeply. Black Tom would be too interested in his charts to hear what little sound he might make.

At the huge oval door leading into the power room, Joe halted, breathing deeply. Then, quietly, easily, he swung open the heavy door, stepped inside, his eyes searching for Black Tom.

Softly, he pulled the portal closed, stood there breathing in long, quiet breaths. Then he moved across the huge power room, feet moving as cautiously as if he were stalking a deer in the autumn woods.

Black Tom's head was bent over a report sheet, his fingers were busy with a pencil. He shook his head, and Joe was motionless. Then a chuckle came from Black Tom's lips, and under cover of the sound, Joe made for the ladder leading to the water compartment.

Black Tom's head lifted as if startled; his head began to turn toward the exit door. Joe went up the ladder like a frightened monkey, fairly blasted himself through the cubbyhole at the top and then rolled quietly inside.

He lay there, his heart pounding with the quick exertion as he heard Black Tom's footsteps moving across the floor. He held his breath; Black Tom's grunt of puzzlement came muted to his ears. The footsteps returned to the chart table, and Joe risked a look to see Black Tom's head once more bent in study.
