MS 2733 originally contained Uchean linguistic notes and the legend of how the South Wind lost his ears, collected by Truman Michelson (11 pages). In January 1929, these materials were sent by Matthew W. Stirling, chief of the Smithsonian's Bureau of American Ethnology, to Gunter Wagner. The present location of the Uchean notes and text is unknown, and MS 2733 now only contains a copy of Stirling's letter of transmittal to Wagner.
