Amazing Stories Quarterly
According to Milton Wolf and Mike Ashley, historians of science fiction, over the next two years Sloane published some of the best sf of the early years of the field in "Amazing Stories Quarterly". Wolf and Ashley cite "Paradox", by Charles Cloukey, an early time-travel story; "The Bridge of Light", by A. Hyatt Verrill, a novel about a lost civilization in South America; "The Birth of a New Republic", by Miles J. Breuer and Jack Williamson, in which a man of the 24th century reminisces about a revolt by the inhabitants of the Moon against the Earth; "Paradise and Iron", by Breuer; and "White Lily", by Eric Temple Bell, under the pseudonym John Taine, about a form of crystal life that endangers the planet. After 1931, according to Wolf and Ashley, the fiction in "Amazing Stories Quarterly" became less entertaining. Everett Bleiler, the author of a detailed review of the first ten years of science fiction magazines, is less complimentary, describing John W. Campbell, Jr.'s space operas, which appeared from 1930 to 1932, as "turgid", and commenting that only a dozen or so of the stories in the magazine's entire run "might have been considered worth reading if one could put oneself back in the 1930s, accepting the standards of the time". Bleiler mentions three authors, Coblentz, Taine, and Breuer, as having produced notably original material, but adds that their work was "not strong enough for mainstream fiction" and had "too little action and too much sophistication for pulp". Bleiler does however agree with Wolf and Ashley that the magazine's quality declined over time. Brian Stableford, in the "Science Fiction Encyclopedia", also highlights Coblentz, Taine and Breuer, along with Williamson and Verrill, among the magazine's contributors; Stableford regards their contributions as being among "the most important early pulp sf novels".
