When I was in graduate school I was startled to find this story's source
in The John Collier Reader, - or so I have always believed until this
afternoon, when I first riffled, then paged carefully, front to back,
back to front, through the local copy (Knopf, 1972) and discovered no
trace of such a story anywhere in the book.
