16 BUREAU OF AMERICAN ETHNOLOGY 
crania are of low type, this was a characteristic appearing 
among many comparatively recent mound-building tribes. 
At the beginning of the fiscal year the Bureau was fortu- 
nate enough to enter into arrangements with Prof. Herbert 
E. Bolton, of the University of Texas, for recording the 
history of the Texan tribes. During the early historical 
period the French controlled and came into intimate relations 
with the northern Caddo, hence the early history of this group 
is to be found chiefly in French records; but with this excep- 
tion it is mainly in Spanish documents, scattered and almost 
wholly unprinted. These facts make the task in every sense 
a pioneer one. 
The Spanish manuscript sources available to Professor 
Bolton, and upon which, aside from the printed French 
sources, he has thus far mainly drawn, consist of (1) the 
Béxar archives, a rich collection of perhaps 300,000 pages of 
original manuscripts that accumulated at San Antonio during 
the Spanish occupancy, now in the University of Texas; 
(2) the Nacogdoches archives, a similar but much smaller 
collection that accumulated at Nacogdoches and that is 
now in the State Historical Library; (3) the Lamar papers, a 
small collection of Spanish manuscripts, now in private 
hands; (4) mission records preserved at the residence of the 
Bishop of San Antonio; (5) copies of documents from the 
Archivo General of Mexico, belonging to the University of 
Texas and to Professor Bolton; and (6) the various Mexican 
archives. From these have been extracted a great many 
notes, but much material yet remains to be examined. 
During the year Professor Bolton’s efforts have taken three 
principal directions: (1) He has systematically and fully 
indexed, on about 10,000 cards, a large amount of the early 
material, including tribal, institutional, linguistic, historical, 
and other data on the whole Texas field. (2) From this 
material as a basis he has written for the Handbook of 
American Indians many brief articles on tribes and missions, 
ageregating about 20,000 words. (8) While in the analysis of 
the materials and the making of the index cards he has 
covered the whole field, in the final work of construction he
