The following excerpt is from a book about the rituals of the Navajos that have been practiced for thousands of years: During my visit to the Southwest, in the summer of 1885, it was my good [luck] to arrive at the Navajo Reservation a few days before...a Navajo healing ceremonial. Learning of the preparation for this, I decided to remain and observe the ceremony, which was to continue nine days and nights. The [event] drew to the place some 1,200 Navajos. The scene of the [crowd] was a [wide] plateau near...Keam's Canyon, Arizona.
