didn't consist of racial stereotypes. They decided to base the plot on a folktale which Hurston had collected in Florida during one of her anthropological field trips. The two writers dictated their work to Louise Thompson, who typed it. Their work was almost complete in June, when Hurston went away for the summer. She took her notes and said she would return in the fall, and they could finish the play. When Hurston came back, she would not return telephone calls from Hughes. She felt he wanted Thompson to be considered a third collaborator in the project, a proposal to which she strongly objected. Concurrently, Hughes was in the process of severing his relationship with their common literary patron, Charlotte Osgood Mason (Mrs. Rufus Osgood Mason). Reviewers have conjectured that Hurston may have been trying to protect her own relationship with Mason by shunning Hughes. Hurston submitted Mule Bone for copyright in October 1930, listing herself as the only author. In January 1931, Hughes learned that a copy of Mule Bone, bearing only Hurston's name, had been sent to the Gilpin Players, an all-black theater company in Cleveland, for their consideration. Hurston told Hughes that she had not sent them the play, which was true, but Hughes was furious. Hurston had sent Mule Bone to Carl Van Vechten, who sent it on to the Gilpin Players without her knowledge. Hughes sent a copy to apply for copyright under both their names. In the meantime, the Gilpin Players wanted to stage the play. The work was still somewhat rough, but Hughes was in Cleveland, and he offered to help rewrite portions of the play. Hurston sent a telegram advising that she refused to allow the production. A day later, she sent another telegram authorizing the production on the condition that she be allowed to work with Hughes on changes. That same day, Hughes received a letter from Hurston saying that no part of the play had been written by him. In light of all the off-stage drama, the Gilpin Players decided not to proceed with their production. The copy of Mule Bone in the Langston Hughes papers at Yale University has a hand-written notation by Hughes: "This play was never done because the authors fell out." 1991 production Mule Bone was produced for the first time in 1991 by the Lincoln Center Theater, more than 60 years after it was written.
