Richard Sharpe Shaver was then living in Barto, Pennsylvania, and operated a welding machine in a war plant. In writing to thank the editor for publishing his letter, he enclosed a manuscript called “Warning to Future Man” which purported to give his memories of life in the fabled continent of Lemuria. The information had been preserved in “thought records” hidden in secret caves. By “telaug,” a kind of audio-visual telepathy, he had begun to remember his forgotten past when, through the noise of his welding machine, he heard voices. After visiting Shaver and probing his “memories,” Palmer bought the story. He didn’t like the way it was written, however, so he rewrote it, added material that expanded it to three times its original length[II-9], changed the title to “I Remember Lemuria,” and started advertising it well in advance of publication as a _true_ story: “Twelve thousand years ago the Lemurians and the Atlanteans disappeared from the Earth. Where and why did they go?”[II-10] This story would show that Newton and Einstein were all wrong, Palmer promised, and would reveal new concepts of gravity, the nature of matter, and the foundation for physical mathematics. Thus began the controversy that rocked the world of science fiction. Since Palmer has affirmed that “Flying saucers are a part of the Shaver Mystery--integrally so”[II-11], we turn to the old files of _Amazing Stories_ to trace their development. The first of the Shaver series, “I Remember Lemuria” appeared in March 1945[II-12], along with “Mantong, The Language of Lemuria,” an article signed by both Shaver and Palmer, and other stories followed quickly in succeeding issues of _Amazing_. The basic themes were shopworn--a jumble of Fortean ideas, Plato’s fables, and mystic science--but when brightened by Palmer’s magic pencil, they seemed fresh and exciting: The earth had an ancient past, now forgotten. The lost continents of Atlantis, Lemuria, and Mu had been colonized many thousands of years ago by superior beings from another planet who could travel through space by utilizing forces unknown to present-day earthmen. Eventually these noble aliens had been forced to abandon the earth to escape evil radiations coming from our sun, but they had left descendants who still lived on earth in concealment in great subterranean cities that could be entered through certain caves. The underground dwellers in the hidden world had retained all the secret powers of their ancestors. They could communicate by thought transference, could speak to earthmen by mental “voices,” and could travel on beams of light because they understood the true nature of gravity and magnetism. These creatures were divided into two opposing groups, one good and one evil. The dero (detrimental robots) were the bad guys and they caused all the unexplained accidents and misfortunes that happen to human beings. The tero (integrative robots) were the good guys; they warned earthmen
