of van Vogt's best-liked stories, and "War of Nerves", part of his Voyage of the Space Beagle series. Fritz Leiber contributed "The Seven Black Priests", one of his Fafhrd and the Gray Mouser stories, and E.E. Smith, who had become famous for his space operas, switched to fantasy with "Tedric", which appeared in the March 1953 issue. Poul Anderson and Gordon R. Dickson contributed "Heroes Are Made", the first in their Hoka series, and Palmer obtained fiction from other well-known writers such as Fredric Brown and Wilson Tucker. Partly because of competition from the newly-launched Galaxy Science Fiction and The Magazine of Fantasy & Science Fiction, Palmer was unable to obtain enough material of this quality to fill the magazine, and most of the remaining stories were unremarkable space adventures. Ashley comments that the stigma of the Shaver Mystery clung to Palmer and damaged the magazine; and suggests that much of the best-quality work in Other Worlds was due to the influence of Mahaffey, who in Ashley's opinion "had excellent taste in fiction". A high point of the non-fiction pieces was a series of articles by L. Sprague de Camp, abridged from his book Lost Continents: The Atlantis Theme in History, which ran from 1952 to 1953. The covers were attractive, often with artwork on both covers, by well-known artists such as Malcolm Smith, Robert Gibson Jones, Harold McCauley, and Hannes Bok.Science Stories maintained the same high quality of artwork. The first issue, dated October 1953, was painted by Bok, who also did the interior illustration for Jack Williamson's story based on the cover. The remaining three covers were by Virgil Finlay, Albert A. Nuetzell, and Jones; Wendy Bousfield, an sf historian, considers the last one the best, and also singles out the last issue's interior illustrations, all by Finlay, for praise. The writing was not up to the standard of the artwork, with Jack Williamson and Mack Reynolds the only two authors whose reputation has lasted. A lower page count meant less non-fiction material and readers' departments (such as letters) in Science Stories than in Other Worlds, but Palmer found space for cartoons and advertisements for his own books, such as The Coming of the Saucers, written with Kenneth Arnold. Science Stories was visually attractive but lacked memorable fiction. Universe Science Fiction took the opposite approach, with uninteresting covers and poor interior artwork, but it had some good stories
