"Perfectly, sir." The disintegrator ray generators deepened their purr as I turned away. "I trust, sir, that I did the right thing in following you with the _Ertak_?" asked Hendricks. "I was absolutely without precedent, and the circumstances were so mysterious--" "You handled the situation very well indeed," I told him. "Had you not been waiting when we fought our way into the open, the nearly invisible things on the outside might have--but you don't know about them yet." Picking up the microphone again, I ordered a pair of searchlights to follow the disintegrator ray, and made my way forward, where I could observe activities through a port. The ray was boring straight down into a shoulder of a rocky hill, and the bright beams of the searchlights glowed redly with the dust of disintegration. Here and there I could see the shadowy, transparent forms of the creatures that the self-constituted rulers of this world had doomed to a demi-existence, and I smiled grimly to myself. The tables would soon be turned. * * * * * For perhaps an hour the ray melted its way into the solid rock, while I stood beside Ott and his crew, watching. Then, down below us, things began to happen. Little fragments of rock flew up from the shaft the ray had drilled. Jets of black mud leaped into the air. There was a sudden blast from below that rocked the _Ertak_, and the shaft became a miniature volcano, throwing rocky fragments and mud high into the air. "Very good, Ott," I said triumphantly. "Cease action." As I spoke, the first light of the dawn, unnoticed until now, spread itself over the scene, and we witnessed then one of the strangest scenes that the Universe has ever beheld. Up to the very edge of that life-giving blast of mineral-laden gas the tenuous creatures came crowding. There were hundreds of them, thousands of them. And they were still coming, crowding closer and closer and closer, a mass of crawling, yellowish shadows against the sombre earth. Slowly, they began to fill out and darken, as they drew in the fumes that were more than bread and meat and water to us. Where there had been formless shadows, rotund creatures such as we had met in the cavern stood and lashed their tentacles about in a sort of frenzied gladness, and fell back to make room for their brothers. * * * * * "It's a sight to make a man doubt his own eyes, sir," said Correy, who had come to stand beside me. "Look at them! Thousands of them pouring from every direction. How did it happen?" "It didn't happen. I used our disintegrator ray as a drill; we simply sunk a huge shaft down into the bowels of the earth until we struck the source of the vapor which the self-appointed 'ruling class' has bottled up. We have emancipated a whole people, Mr. Correy."
