 What does the E.P. Locator detect?
[Transcriber's Note: This etext was produced from Worlds of If Science Fiction, March 1961. There was one more test to run, one very tricky and difficult of analysis, that with the Extraordinary Perception Locator. The E. P. Locator had been designed by Glaser. But when the Locator had refused to read Positive when turned on the inventor himself, bad blood developed between machine and man. And there was no denying that the Extraordinary Perception Locator (or Eppel) was a contrary machine. On Earth it had read Positive on a number of crack-pots, including Waxey Sax, a jazz tootler who could not even read music. He then narrowed to a smaller area (apparently one individual, though this could not be certain) and got very definite action.
