There are but three or four different languages spoken among them, and these, indeed, may be distantly allied to each other. Those of Taos, Picuris, Isleta, and perhaps some others, speak what has been called the _Piro_ language. A large portion of the others, viz., those of San Juan, Santa [Pg056] Clara, Nambé, Pojuaque, Tezuque, and some others, speak _Tegua_, having all been originally known by this general name; and those of Cochití, Santo Domingo, San Felipe, and perhaps Sandía, speak the same tongue, though they seem formerly to have been distinguished as _Queres_. The numerous tribes that inhabited the highlands between Rio del Norte and Pecos, as those of Pecos, Ciénega, Galisteo, etc., were known anciently as _Tagnos_, but these are now all extinct; yet their language is said to be spoken by those of Jemez and others of that section. Those further to the westward[19] {270} are perhaps allied to the Navajoes. Though all these Pueblos speak their native languages among themselves, a great many of them possess a smattering of Spanish, sufficient to carry on their intercourse with the Mexicans.[20] The population of these Pueblos will average nearly five hundred souls each (though some hardly exceed one hundred), making an aggregate of nine or ten thousand. At the time of the original conquest, at the close of the sixteenth century, they were, as has been mentioned, much, [Pg057] perhaps ten-fold, more numerous.[21] Ancient ruins are now to be seen scattered in every quarter of the territory: of some, entire stone walls are yet standing, while others are nearly or quite obliterated, many of them being now only known by their names which history or tradition has preserved to us. Numbers were no doubt destroyed during the insurrection of 1680, and the petty internal strifes which followed. Several of these Pueblos have been converted into Mexican villages, of which that of _Pecos_ is perhaps the most remarkable instance. What with the massacres of the second conquest, and the inroads of the Comanches, they gradually dwindled away, till they found themselves reduced to about a dozen, comprising all ages and sexes; and it was only a few years ago that they abandoned the home of their fathers and joined the Pueblo of Jemez.
