When Coronado reached "Tiguex" at last, it thereafter became the centre of his operations. Castañeda very justly remarks: "Tiguex is the central point;"[67] and a glance at the map, substituting Bernalillo for it, will at once satisfy the reader of the accuracy of this statement. From Tiguex an expedition was sent along the Rio Grande and west of it. It discovered in succession: Quirix on the river, with seven villages; Hemes with seven villages; Aguas Calientes, three; Acha to the north-east; and, furthest in a north-easterly direction, Braba. Four leagues west of the river, Cia was met with; and, between Quirix and Cicuyé, Ximera. Further north of Quirix, Yuque-Yunque was found on the Rio Grande. An officer was also despatched to the south beyond Tutahaco, and he indeed discovered "four villages" at a great distance from the latter, and beyond these a place where the Rio Grande "disappeared in the ground, like the Guadiana in Estremadura."[68] Through our identifications of "Tiguex" with _Bernalillo_, of "Cicuyé" with _Pecos_, and "Tutahaco" with _near Isleta_, it becomes now extremely easy to locate all these pueblos in the most satisfactory manner. "Quirix" is the _Queres_ district Santo-Domingo, Cochití, etc.[69] "Hemes" and "Aguas Calientes," together form the _Jemez_ and _San Diego_ clusters of pueblos,[70] "Acha" is _Picuries_, "Braba," _Taos_.[71] The pueblo of "Ximera" between Pecos and Queres is the _Tanos_ pueblo of _San Cristóbal_.[72] "Yuque-Yunque" are the _Tehuas_, north of Santa Fé,[73] and the four villages on the Rio Grande far south of Isleta, naturally are found in the now deserted towns of the "Piros" near Socorro, the most southerly and the least known of the linguistical stocks of sedentary Indians in New Mexico.[74] In sending the officers mentioned along the Rio Grande, as far south as Mesilla probably, Coronado explored the territory beyond the range of the pueblos, and he thus secured information also concerning the roaming tribes. It is essential that I should touch these here also, because the subsequent history of the village Indians cannot be understood without connection with their savage surroundings. I might as well state here, that west of the Rio Grande and south of Zuñi, the entire south-west corner of New Mexico, appears to have been uninhabited in 1540. Stray hunting parties may have visited it, though there was hardly any inducement, since the buffalo was found east of the Rio Grande only, as far as New Mexico is concerned.[75]
