10 BUREAU OF AMERICAN ETHNOLOGY 
( 
other group of tribes, as Pueblo written history commenced 
in the year 1539, and the writings pertaining thereto are 
exceedingly voluminous. The bibliography is recorded on 
cards, the number of which is now about 1,900. The cata- 
loguing of the vast amount of manuscript material bearing on 
the subject has been somewhat simplified by the recent publi- 
cation of Bolton’s Guide to Materials for the History of the 
United States in the Principal Archives of Mexico, published 
by the Carnegie Institution of Washington, and Twitchell’s 
Spanish Archives of New Mexico, although without consulta- 
tion of the documents themselves it is not possible to give 
more than the title in most cases. In the spring Mr. Hodge 
made a brief visit to the library of the Presbyterian Board 
of Home Missions in New York City, where he was enabled 
to record the titles of numerous published writings on mis- 
sionary efforts among the Pueblo Indians of New Mexico, not 
accessible elsewhere. In this bibliographical work he has had 
the assistance of Mrs. Frances $8. Nichols and Miss Florence 
M. Poast. Mr. Hodge continued to represent the bureau on 
the Smithsonian Advisory Committee on Printing and Publi- 
cation, and the Smithsonian Institution on the United States 
Board on Geographic Names. 
Early in the autumn of 1913 Mr. Hodge made a reconnois- 
sance of a group of ruins, evidently prehistoric, on a mesa 
rising from the southwestern margin of the Cebollita Valley, 
about 20 miles south of Grant, Valencia County, New Mexico, 
and only a few yards from the great lava flow that has spread 
over the valley to the westward for many miles. While no 
very definite information regarding the origin of this ruined 
pueblo has yet been obtained, there is reason to suppose that 
it was occupied by ancestors of the Tanyi, or Calabash, clan 
of the Acoma Tribe, and is possibly the one known to them 
as Kowina. 
These ruins consist of a number of house groups forming a 
compound. That the structures were designed for defense 
is evident, for not only are they situated on an almost impreg- 
nable height rising about 200 feet above the valley, but the 
houses themselves partake of the form of fortifications,
