Cylinder recordings of Navajo Indian songs, probably complied by Geoffrey O'Hara, and lantern slides of Navajo Indians in Arizona, circa 1913-1914. The recordings consist chiefly of songs related to the Navajo Yeibichai ceremony. Singers include Robert Dayea, Shay Milford, and Miguelito (also known as Red Point). Lantern slides include informal portraits of Navajo men, women, and children in Fort Defiance and at the Hubbell Trading Post in Ganado. The collection also includes a portrait of O'Hara with Denver, a Shoshoni Indian man. Images include Navajo Indian ceremonies and dances, as well as foot and horse races. Images of Arizona include views of desert landscapes and arroyos with sheep and goats, as well as a view of the White House Ruins at Canyon de Chelly. Copy photographs in the collection include a portrait of Navajo Chief Manuelito, circa 1874, and illustrations of Navajo Yeibichai masks from Washington Matthews's anthopological study, Night Chant: A Navaho Ceremony (1902).
