At the time of the advent of Tobar, in 1540, there was but one of the present three villages of East Mesa. This was Walpi, and at the period referred to it was situated on the terrace below the site of the present town, near the northwestern base of the mesa proper. Two well-defined ruins, called Kisakobi and Küchaptüvela, are now pointed out as the sites of Old Walpi. Of these Küchaptüvela is regarded as the older. Judging by their ruins these towns were of considerable size. From their exposed situation they were open to the inroads of predatory tribes, and from these hostile raids their abandonment became necessary. From Küchaptüvela the ancient Walpians moved to a point higher on the mesa, nearer its western limit, and built Kisakobi, where the pueblo stood in the seventeenth century. There is evidence that a Spanish mission was erected at this point, and the place is sometimes called Nüshaki, a corruption of "Missa-ki," Mass-house. From this place the original nucleus of Walpians moved to the present site about the close of the seventeenth century. Later the original population was joined by other phratries, some of which, as the Asa, had lived in the cliff-houses of Tségi, or Canyon de Chelly, as late as the beginning of the eighteenth century. This, however, is not the place to trace the composition of the different modern villages. Sichomovi was a colony from Walpi, founded about 1750, and Hano was built not earlier than 1700. The former was settled by the Badger people, later joined by a group of Tanoan clans called the Asa, from the Rio Grande, who were invited to Tusayan to aid the Hopi in resisting the invasions of northern nomads. By the middle of the eighteenth century the population of the province of Tusayan was for the first time distributed in the seven pueblos now inhabited. No village has been deserted since that time, nor has any new site been occupied. In order that the reader may have an idea of the Tusayan pueblos at the time mentioned, an account of them from a little-known description by Morfi in 1782 is introduced:[32] _Morfi's account of the Tusayan pueblos_ Quarenta y seis leguas al Poniente de Zuñi, con alguna inclinacion al N. O. están los tres primeros pueblos de la provincia de Moqui, que en el dia en el corto distrito de 4-1/2 leguas (112 recto) tiene siete pueblos en tres mesas ó peñoles que corren linea recta de Oriente á Poniente. _Tanos_[33] En la punta occidental de la primera, y en la mas estrecho de su eminencia están situados tres de los quales el primero es el de Tanos (alli dicen Tegüas), cuyas moradores tienen idioma particular y distinto del Moquino. Es pueblo regular con un plaza en el centro, y un formacion de calles. Tendrá 110 familias. El segundo[34] pueblo dista del precedente como un tiro de piedra, es de fundacion moderna, y se compondrá de mas 15 familias que se retiraron aqui de: _Gualpi_
