In attempting to connect the oval form of Fire House with the rectangular form of Sikyatki we are met with the difficulty of architectural dissimilarity. Fire House is circular, Sikyatki is rectangular. If the descendants of the inhabitants of Fire House later constructed Sikyatki, why did they make this radical change in the form of their dwellings? They may have constructed a habitation en route before they reached Sikyatki, and this village may have had a form like Fire House. On the Hopi plateau above Sikyatki there are two conical mounds visible for a long distance as one approaches East Mesa from the mouth of Keam’s Canyon, which should be considered in this connection. These mounds, called Kükütcomo, are connected in Hopi legends with those of Sikyatki at the foot of the mesa on which they stand, and the buildings they cover are said once to have been inhabited by the Coyote (Fire?) clan of eastern kinship. They have not been excavated completely but several rooms have been opened up enough to show that they are round towers or kivas with rooms annexed to their bases. They resemble, in fact, circular ruins and may well have been the home of some of the people who abandoned Fire House. They must be considered in discussing the reliability of the legend, for they are the only circular houses yet reported from the Hopi country. The reason why this form of house was abandoned can not be determined with any certainty, even though some of the clans from Fire House may have built the round towers above Sikyatki. The only other round room known to me in the Hopi country, besides Kükütcomo, is one in a ruin in the Oraibi Valley mentioned by Victor Mindeleff (_op. cit._). The reference is very meager and on account of its exceptional character should be verified. Assuming the observation as correct it may be said that this so-called circular room lies embedded in a mass of rectangular rooms and not as kivas in the inhabited Hopi pueblos in the plazas free from houses. The legends of the Snake people of Walpi who came from the San Juan near Navaho Mountain, probably Betatakin or Kitsiel, distinctly state that their ancestors built both round and square or “five-cornered” houses. The rooms referred to are believed to be kivas, since another legend declares the earliest snake ceremonies were performed in circular rooms. After visiting Fire House the author desired greatly to find other oval ruins between it and the zone of circular ruins, but his efforts were not successful. SEARCH FOR HOPI RUINS EAST OF TEBUNGKI
