John Gregory Bourke kept a monumental set of diaries as aide-de-camp to Brigadier General George Crook. This fifth volume opens at Fort Wingate as Bourke prepares to visit the Navajos. Next, at the Pine River Agency, he is witness to the Sun Dance, where despite his discomfort at what he saw, he noted that during the Sun Dance piles of food and clothing were contributed by the Indians themselves, to relieve the poor among their people. Bourke continued his travels among the Zunis, the Rio Grande pueblos, and finally, with the Hopis to attend the Hopi Snake dance. The volume concludes at Fort Apache, Arizona, which is stirring with excitement over the activities of the Apache medicine man, Nakai'-dokli'ni, which Bourke spelled Na Kay do Klinni. This would erupt into bloodshed less than a week later. Volume Five is particularly important because it deals almost exclusively with Bourke's ethnological research. Bourke's account of the Sun Dance is particularly significant because it was the last one held by the Oglalas. The volume is extensively annotated and contains a biographical appendix on Indians, civilians, and military personnel named.
