For the period between 1630 and the uprising of 1680 there is a lack of printed documents concerning New Mexico that is poorly compensated by the known manuscripts which I have already mentioned as existing in New Mexico and Mexico. Still there appeared in 1654 a little book by Juan Diez de la Calle, entitled _Memorial y Resumen breve de Noticias de las Indias Occidentales_, in which the disturbances that culminated in the assassination of Governor Luis de Rosas in 1642 are alluded to. The national archives at the City of Mexico contain a still fuller report of that event, in a royal decree of 1643 and other papers concerning the deed, all of which are yet unpublished. The archives of Spain have as yet been only meagerly investigated. The publication of the report of Father Nicolas de Freytas, Portuguese, on the expedition attributed to Diego de Penalosa Brizeno into what is now Kansas or Nebraska, is of no importance in the study of the Rio Grande Pueblos. The authenticity of the document has been strongly doubted, though probably without just cause. Equally unimportant to the subject of the Documentary History to follow is the letter of Captain Juan Dominguez de Mendoza, published in the appendix to the criticism of Cesareo Fernandez Duro on the report of Father Freytas. The otherwise very interesting letter on New Mexico, written by Fray Alonso de Posadas, also printed in the work of Duro, is meager in its allusions to the Rio Grande. Sixty-eight years after Benavides' time the _Teatro Mexicano_ of the Franciscan Fray Agustin de Vetancurt was published. The third and fourth parts of this important work, namely, the _Cronica de la Provincia del Santo Evangelio de Mexico_ and the _Menologio Franciscano_, are of the highest value to the history of the Rio Grande Pueblos and of New Mexico generally. Although printed eighteen years after the New Mexican missions had been destroyed by the Pueblo Indians, the _Cronica_ contains a terse description of the missions and Indian villages as they had been previous to 1680, and gives data in regard to the population that are commendable in their sobriety and probability. The work of Vetancurt is in this respect a great improvement upon Benavides, and it is interesting to note how his approximate census approaches the figures given by Zarate Salmeron seventy years before. Vetancurt had at his disposal much more precise data than Benavides. During the seven decades separating the three authors much information had been accumulated, and with greater chances of accuracy than before. Vetancurt made good use of this accumulation of material, and his books are in fact the most reliable sources from which to ascertain the status of the Pueblos at the time the insurrection commenced. The historical data given by Vetancurt in regard to New Mexico during earlier times are not of great value, but the _Menologio_, as well as the _Cronica_, contains
