"Oh, don't be modest, my dear fellow!" smiled the dwarf. "I am the last one to belittle your achievement. Indeed, it is because of it that I have invited you here to-day. Permit me to introduce myself, and to make clear one or two possibly perplexing matters. Then I am sure we shall have a most agreeable chat."
is name was Cor, he said, and he was in truth the monarch of this strange realm. His people had come from the one-time planet of Vada, far distant in the universe. A thousand years ago, this planet had been doomed by the approach of an alien star. Their great scientist, Ravv, had met the emergency by inventing the disc, into whose construction they had poured all their resources. The pick of their populace had been salvaged on this giant life-raft. The rest had perished when that destroying star had crashed down on the doomed Vada.
Since then these survivors and their descendants had been voyaging through space on their marvelous disc. For hundreds of years they had given no thought to the future, content to drift on and on in the interstellar void, breathing an atmosphere produced artificially. But at length the inevitable had happened. This superb piece of mechanism devised by their super-genius, Ravv, was beginning to show signs of wear. Some of its mighty engines were nearing the exhaustion point. Either they must soon find a planet comparable with the one they had once known, where they could pause and rehabilitate their machinery, or they must disintegrate and pass into oblivion.
Faced with that crisis, Cor had long been seeking such a planet. He had found it, at last, in the earth—and had resolved that this was where they were going to alight and transplant the civilization of ancient Vada, pending such time as they could take to space again.
or some months now they had been hovering over various portions of the earth, studying its geography and its peoples, with the result that they had concluded the United States offered the most logical point for launching the attack. Once this country was subdued, they were in possession of the richest and most advanced section of the planet. The conquest of the rest of it could await their leisure.
With such an invasion in view, their scientists had mastered the language of the country. This had been accomplished very easily, since in addition to their power of mingling with the populace in an invisible form, they had the principles of radio developed to a high degree and were able to tune in on any station they wanted.
