Archie Sparrow (Sparrow) (plaintiff), a cowboy experienced in training horses agreed with Morris (defendant) who owned a cattle ranch in Arkansas, that Sparrow would perform work at Morris's ranch while Morris was away. They agreed that Sparrow would be paid $400 for this work and that Morris would give Sparrow a horse named Keno as additional compensation if the work was satisfactory. While Sparrow was working at the ranch he trained Keno, who was almost unbroken. As a result of Sparrow’s training, Keno needed only a small amount of additional training to become a quality roping horse. When Morris returned, he paid Sparrow $400, but refused to turn over Keno, asserting that Sparrow did not do good work. Sparrow brought an action against Morris in Chancery Court for specific performance of the agreement. Morris argued that the condition of satisfactory work had not been met, so he was not obligated to turn over Keno. The Chancery Court directed that Morris deliver Keno to Sparrow. Morris appealed.
