He ducked under the gleaming neck and watched it crash into the bigger machine's lower section, sending it bouncing rearward on stumpy legs. The master robot lashed back, slashing a gaping slit in the MA's neck. Into this fury of swinging appendages Stewart decided he would have to hurl himself if he expected to immobilize the telepuppet team. As unpredictable as the robots were, he might never get this close to the master automaton again. The flow of battle, however, made his decision unnecessary. For the grappling machines were now sweeping over the spot where he lay and a huge pedal pad barely missed him as it thudded down. For a fleeting instant, the recessed compartment was immediately above his head. Overcoming the ponderous weight of his mailed arm, he reached up and flicked open the lid. At the same time he managed to get a finger on and throw the switch. One final kick by the OC hurled him from beneath the tons of metal. Meanwhile, the thing's thrashing vise caught the MA broadside and sent it flailing backward. Then the master puppet toppled over like a towering tree being felled by an ancient woodsman's chain saw. The ground trembled violently with the impact. Stewart rose and wiped dust from his helmet's view plate. The monstrous robot lay motionless, darkened ports evidencing its lifelessness. Close by, the Mineral Analyzer stumbled around in looping circles, one of its gyros atilt. The other puppets continued their work, unaware that when all stored energy was depleted there would be no opportunity to recharge their batteries. Exhausted, his face filmed with perspiration and his hip aching beneath the dent the big machine had kicked in his armor, Stewart headed back for the ship. But his release from urgency lightened his steps somewhat. Now there would be little to do but wait until the lesser puppets ran out of power. * * * * * An automatic erector leveled Minnie's tilted gyro. Another emergency maintenance circuit cut in and compensated for precession. Finally her sense of balance was restored. Rationalization circuits reasoned out the precise maneuver necessary to bring her upright and she rose upon her motor appendages, expecting at any moment to be bludgeoned again by Bigboss' vise. Slowly she turned and sent her restricted field of vision sweeping across the ground. And her video lens came to focus on-- Bigboss! In a most unusual position! And--_motionless_! He was stretched out on the ground, extensible vise limp as it lay half covered by the soil into which it had dug. One of his antennae was crumpled beneath him while the other was bent and twisted. Hardly able to accept as valid the visual data she was receiving, she transmitted an unwarranted "please-verify-that-instruction" impulse at low volume. Her evaluation circuit was thrown almost into a frenzy when there was no response. At maximum gain, she repeated the signal. _Still_ no response!
