erly at the pueblo of Santa Clara and now preserved at Santa Fe
through the efforts of the late Archbishop J. B. Salpointe. There are
also the "Informaciones Matrimoniales," which contain data of great
importance. Through them we are informed of the tragic fate of the last
expedition of the Spaniards to the northwest, with its horrifying
incidents. The story of woe and disaster that pictures the life of the
Indian Pueblos and Spanish settlers during the eighteenth century is
contained in fragments in the plain, matter-of-fact church registers,
and it requires painstaking investigation to collect it. The greatest
part of this information concerns the Rio Grande Pueblos. A careful
investigation of the matrimonial and baptismal registers will yield data
concerning the clans and indications of the primitive rules of marriage,
while the "Libros de Fabrica" contain interesting data on the churches
of the Rio Grande valley. Great labor and the utmost scrutiny are
required in sifting these time-worn papers for desirable data, and
especially is a considerable knowledge of conditions and events
necessary; but the result of thorough investigation, especially through
literal copying by the student, will amply repay the time and labor
bestowed.

What I have stated in regard to the church archives applies, in a still
greater degree, to the state and private papers that may be accessible.
Of the former the archives of Santa Fe contain a great number, though
many of them are only fragmentary. Valuable documents exist also in the
archives of the Surveyor General at Santa Fe; these are valuable chiefly
for historical data covering the first half of the eighteenth century.
The national archives in the City of Mexico are much more complete than
those of New Mexico, while in Spain we may expect to find an almost
complete set of government documents, preserved with much greater care
and with more system than in any early Spanish possessions in America.
The city of Sevilla would be the first place in which research in this
direction should be conducted.

Before closing this bibliographic sketch with a glance at the earliest
literature of the nineteenth century, I must mention two ponderous books
of the eighteenth century which, while based on second-hand information
and not very valuable in detail, refer occasionally to facts and data
not elsewhere found. These are the two volumes of the _Cronica
Apostolica y Serafica de la Propaganda Fide d
