The spiralled figures turned in alarm back toward their craft. One of them, hovering close to our haven of retreat, did not follow his comrades. Instead, he drew forth from a long side pocket a black object. At first glance, it seemed shaped like a pistol. But it was much longer and was proportioned differently. He waited patiently until several more of the brigands had returned to the ship. Raising the black weapon, he aimed carefully at his fellow outlaws. The man's strange actions amazed me. He was turning upon his own comrades. Several of the brigands fell backward off the deck of the outlaw craft. Cragley, beside me, was speechless in surprise at the rapid succession of events. The outlaw's strange weapon which emitted no flash had us all wondering. Later, we discovered that it was a radium gun, a new instrument of destruction still in the experimental stage. "Who is he?" voiced Cragley. "Can't be the fellow we heard over the speaker," observed Quentin. "This man came through the electric fence with the first ones." "Somebody over there is pulling for us," insisted Cragley, "and the man with the black gun must be a friend, too." A flash darted out from the ship, hitting the spiralled figure operating his mystifying weapon. The spiral glowed brilliantly. The man inside the spiral remained unaffected, continuing to manipulate the knob of his weapon. Something went wrong with it, for the outlaw who had so suddenly turned against his friends tinkered with it a moment, then threw it from him in disgust. Meanwhile, the brigands had massed inside the ship. * * * * * With a loud crackling, the speaker's volume was thrown on again. An alarmed voice vibrated in our ears. Above the words came a rattling and banging--also the muffled sound of shouting men. "Jasper! Come t' the control room! I'm locked in! They're bustin' down the door! Bring that gun o' yours! Hurry, lad!" Jasper looked upon his broken weapon, hesitated a moment, then picked it up--butt foremost. Seizing it in cudgel fashion, he made for the ship. "Come on!" roared Cragley exultantly. "Now's our chance!" We found our numbers reduced to ten, but every one of us leaped forward at Cragley's order, ready to stake everything on the one desperate, fighting chance which had come so unexpectedly. We had nearly overtaken the man we had heard addressed as Jasper when a crackling flame of lightning leaped out at us. A hissing roar smote our ear drums and we were temporarily dazzled by an intense light. The aim had been too high. The electric charge had gone over our heads. The man in the control room had frustrated the attempt to electrocute us. Several of the brigands jumped out of the ship to meet us. They still wore the encumbering spirals. A powerful gas of paralyzing effect was shot into our faces. We became as immobile as statues. Jasper, too, was overcome. Instantly, we were divested of our weapons.
