had fallen. Another ruin found in a cave in Sand Canyon is in- 
structive on account of its being the only one yet found with a 
single kiva of the unit type. It was probably a ceremonial cave, 
the room showing scanty evidence of having been inhabited. 
One of the discoveries made was the recognition that the build- 
ings on McElmo Bluff had a crude masonry characterized by stones 
set on edge, the walls being made of adobe and logs. The stones 
of one or more rooms on this site were large, indicating megalithic 
stone houses. All the data assembled indicate that they antedated 
the fine horizontal masonry of the pueblos and cliff dwellings. 
While in the field the chief carried on a correspondence with Mr. 
Van Kleeck, of Denver, owner of the Aztec Spring Euin, which led 
to that ruin being presented to the National Park Service and later 
accepted by the Secretary of the Interior. The presentation of this 
interesting ruin to the Government is important and it is to be hoped 
that it will later be excavated and repaired and thus present an addi- 
tional attraction to tourists and an important aid to the archeologist 
in the interpretation of this type of southwestern ruin. 
In May the chief visited Austin, Tex., and inaugurated work on 
the antiquities of that State, the archeolog^^ of which has been 
neglected. This work is now being prosecuted by Prof. J. E. Pearce, 
of the University of Texas, and bids fair to open up a most instruc- 
tive chapter in a field of which we know comparatively little. Im- 
portant discoveries have been made in the aboriginal workshops and 
village sites at Round Rock and near Austin, where fine flint imple- 
ments are very abundant. The work will be continued into the 
timbered region of eastern Texas, where we find pottery related to 
that of Louisiana and Arkansas and evidences of a radically differ- 
ent prehistoric culture from that of central Texas. 
Mr. James Mooney, ethnologist, at the beginning of the fiscal year 
was at his former field of labor among the Kiowa and associated 
tribes of western Oklahoma, where several months were devoted to 
the collection and revision of material and observations of cere- 
monies among the Kiowa, Comanche, Kiowa Apache, Cheyenne, 
Arapaho, Caddo, and Wichita in continuation of studies of their 
aboriginal heraldry, social and military organization, and religion. 
Since his return to Washington in November he has been employed 
chiefly in the coordination of material obtained in the field and in 
the compiling of data for reply to current letters of ethnologic 
inquiry. 
Dr. John R. Swanton, ethnologist, devoted a considerable part of 
his time during the past year to the collection of material from 
published sources for a study of the economic background of the life 
of the American Indians north of Mexico. This involves an exami-
