in accordance with the act of Congress of June 27, 1944, which pro-

SYSTEMATIC RESEARCHES 
Dr. M. W. Stirling, Chief of the Bureau, left Washington January 
6, 1946, in order to continue work on the Smithsonian Institution- 
National Geographic Society archeological project in southern Mex- 
ico. From the latter part of January until the middle of April, arche- 
ological excavations were conducted at the site of San Lorenzo on the 
Rio Chiquito in southern Veracruz. This was the site discovered by 
Dr. Stirling the preceding year at the conclusion of the work in Chi- 
apas. During the season’s work just concluded a map of the site was 
completed, several of the mounds were cross-sectioned, and a number 
of stratigraphic trenches dug. 
During the course of the work 24 stone monuments were located, in- 
cluding 5 colossal heads of La Venta type, and 2 table-top altars. 
In addition, there were a number of miscellaneous monuments repre- 
senting jaguars and seated figures, both human and anthropomorphic. 
The collections made during the course of the work, after inspection 
in Mexico City, were shipped to Washington. During the period of 
this work, Dr. Stirling was assisted in the field by Dr. Philip Drucker. 
Dr. Stirling returned to Washington on May 9. 
During the fiscal year Dr. Frank H. H. Roberts, Jr., Assistant Chief, 
read and corrected page proof for the article, “The New World 
Paleo-Indian,” which was printed in the general appendix to the 
Annual Report of the Smithsonian Institution for 1944. He prepared 
an article, “Prehistoric Peoples of Colorado,” to be used as one chap- 
ter in a forthcoming history of Colorado which is being published by 
the State Historical Society of Colorado, and another article, “One 
Hundred Years of Smithsonian Anthropology,” to be published in
