he prone figure in the bush leaped up, ran for him. The Mercutian was dead, drilled through the heart. Hilary sheathed his weapon grimly. His task was done. One thing, though. How much of the message had been transmitted? He must know. He vaulted over the side of the flier, fumbled around until he found the receiving apparatus. Then he waited, dreading to hear the silence broken. A minute passed, two minutes, and Hilary breathed a sigh of relief. The message had not gotten through.

Then it came—a tiny sparking, an intermittent hum. Hilary's heart sank with hammering blows. He tried to read the signals, but they were in code, or in the Mercutian tongue, which was just as bad. It was not necessary, though. Headquarters had heard; they knew.

Hilary did not waste an instant in vain regrets. Within an hour the gorge would be a vicious trap; he must get his men out at once. What then he did not know, nor bother. There was the more immediate problem.

He went down the swinging ladder hand over hand, not pausing for the rungs. Every instant was precious now. His hands scorched, but he did not feel the pain.

His flying body collided thudding with a heavy bulk beneath. There was a grunt, the rope jerked from his hands, and two bodies fell cursing, entangled, to the ground. Luckily it was not far distant. He sprang to his feet, found Grim heaving his bulk up more slowly.

Hilary had no time for idle talk.

"Attention, men," he snapped. "We leave at once. You have five minutes to get your arms, ammunition clips and rations, light marching order."

Without a word they scattered alertly to their tasks. It was the discipline of veterans.

"You didn't get the Mercutian?" Grim was troubled.
