It was Keston's voice, but so changed, so packed with fury and outrage, that I scarcely recognized it.

His spare, tall form was drawn tensely straight as he shook a clenched fist at the Council. He was quivering with anger, and his eyes blazed.

"Aristos, you do wrong! These men have served you faithfully and well. I demand for them the reward they have earned—rest and leisure, and the pleasures that for ten years they have seen you enjoy while they worked here for you. They have worked for you, I say, and now that I have released them you would destroy them. Aristos, I demand justice!"

For the first time I saw expression on the flaccid faces of the Council—surprise and astonishment that a prolat should dare dispute an aristo command. Then a sneer twisted Atuna's countenance.

"What is this? Who are you to demand anything from us? We spared these prolats because we needed them: we need them no longer, hence they must die. What madness has seized you? Reward! Justice! For prolats! As well say we should reward the stone walls of our houses; dispense justice to the machines. Proceed, prolats!"

Keston made as if to spring for the aristo's throat. I put out a hand to stop him. An invisible shield of death rays rimmed the platforms the Council used. It was suicide! But suddenly he turned and sprang to the master machine. He grasped a switch lever and threw it down.

A long tentacle left its keys and swished menacingly through the air. "Meron, prolats, under the key-boards!" came Keston's shout. I dived to obey. Steel fingers clutched my jerkin and tore it loose as I landed with a thud against the wall. Keston thumped alongside of me. He was breathing heavily and his face was deathly pale.

"Look!" he gasped.
