iv Introductory Note 
has also been possible to supply in advance a body of references to American 
filibustering in Mexico for the aid of Professor I. J. Cox, notes on materials 
respecting Iturbide for Professor W. S. Robertson, on Santa Anna for Pro- 
fessor Justin H. Smith, and on the American Colonization of Texas for 
Professor E. C. Barker, and on the Gadsden Purchase for Mr. Sears of the 
University of Kansas, and to secure manuscripts useful to Father Zephyrin 
Engelhardt in the preparation of the second volume of his Missions and Mis- 
sionaries of California. On the basis of Mr. Bolton’s notes, moreover, some 
20,000 or more sheets of transcripts have been made in the Mexican archives 
for the Bancroft Library, the Texas State Library, and the University of 
Texas. In all cases it will be the desire of the department, so far as work 
upon the manuscripts of its publications permits, to afford information from 
them in advance for the benefit of historical workers. But it is of course far 
more gratifying to the department, and far more satisfactory to investigators, 
when at length the finished volume can be laid before them. 
The reader is requested to note that the investigations recorded in this 
volume occurred during the presidency of General Diaz, before the beginning 
of the recent disturbances in Mexico. No attempt can now be made to ascer- 
tain in any satisfactory and thorough manner what effects recent develop- 
ments may have had upon archives and their contents.
