We can rely on the statement that Sikyatki was inhabited by the Kokop or Firewood people of Tusayan, who were so named because they obtained fire from wood by the use of drills. These people are represented today at Walpi by Katci, whose totem is a picture of Masauwû, the God of Fire. It is said that the home of the Firewood people before they built Sikyatki was at Tebuñki, or Fire-house, a round ruin northeastward from Keam's canyon. They were late arrivals in Tusayan, coming at least after the Flute people, and probably before the Honani or Badger people, who brought, I believe, the _katcina_ cult. Although we can not definitely assert that this cultus was unknown at Sikyatki, it is significant that in the ruins no ornamental vessel was found with a figure of a _katcina_ mask, although these figures occur on modern bowls. The original home of the Kokop people is not known, but indefinite legends ascribe their origin to Rio Grande valley. They are reputed to have had kindred in Antelope valley and at the Fire-house, above alluded to, near Eighteen-mile spring. The ruin of Fire-house, one of the pueblos where the Kokop people are reputed to have lived before they built Sikyatki, is situated on the periphery of Tusayan. It is built of massive stones and differs from all other ruins in that province in that it is circular in form. The round type of ruin is, however, to be seen in the two conical mounds on the mesa above Sikyatki, which was connected in some way with the inhabitants who formerly lived at its base. The reason the Kokop people left Fire-house is not certain, but it is said that they came in conflict with Bear clans who were entering the province from the east. Certain it is that if the Kokop people once inhabited Fire-house they must have been joined by other clans when they lived at Sikyatki, for the mounds of this pueblo indicate a village much larger than the round ruin on the brink of the mesa northeast of Keam's canyon. The general ground plan of the ruin indicates an inclosed court with surrounding tiers of houses, suggesting the eastern type of pueblo architecture. The traditional knowledge of the destruction of Sikyatki is very limited among the present Hopi, but the best folklorists all claim that it was destroyed by warriors from Walpi and possibly from Middle Mesa. Awatobi seems not to have taken part in the tragedy, while Hano and Sichomovi did not exist when the catastrophe took place. The cause of the destruction of Sikyatki is not clearly known, and probably was hardly commensurate with the result. Its proximity to Walpi may have led to disputes over the boundaries of fields or the ownership of the scanty water supply. The people who lived there were intruders and belonged to clans not represented in Walpi, which in all probability kept hostility alive. The early Tusayan peoples did not readily assimilate, but quarreled with one another even when sorely oppressed by common enemies.
