Howard may have begun losing interest in Conan in late 1934, with a growing desire to write westerns. He began to write, although never finished, a Conan story called "Wolves Beyond the Border". This was the first Conan tale to have an explicit (Robert W. Chambers-influenced) American setting, although American themes had appeared earlier, and the only one in which Conan himself does not appear. His next story was based on his unfinished material and became "Beyond the Black River" which not only used the different American-frontier setting but was also, in Howard's own words, a "Conan yarn without sex interest." In another novel twist, Conan and the other protagonists have, at best, a pyrrhic victory; this was rare for pulp magazines. This was followed by another experimental Conan story, "The Black Stranger", with a similar setting. The story was, however, rejected by "Weird Tales", which was rare for later Conan stories. Howard's next piece, "The Man-Eaters of Zamboula", was more formulaic and was accepted by the magazine with no problems. Howard only wrote one more Conan story, "Red Nails," which was influenced both by his personal experiences at the time and an extrapolation of his views on civilization.
