"Come on!" cried Nielson, leaping from concealment.

There wasn't a person left in sight to oppose them. Fifty yards to cross. Fifty yards to the ship! Fifty yards to a fighting chance for life!

Under their racing feet the soft turf was soundless.

Twenty-five yards to go now. Ten yards. Ten feet to the open lock.

Thulon appeared in the lock. He looked in surprise at the charging men.

Except for the rough staff that he carried he was weaponless.

Nielson didn't give the command to fire, didn't need to give it. Every vibration pistol had been drawn long before the men leaped from cover. Every pistol came up at the same instant, every index finger squeezed a trigger.

Only Thulon stood between them and a fighting chance for life. They came of warrior races, these men. No bugles urged them on. They needed no bugles.

A howling vortex of radiation smashed at the figure in the lock.

One vibration pistol would destroy a man, smash him to bloody bits. More than a dozen pistols were centered on the figure standing before them.
