PREFACE 



The investiofation described in the follow in": paper was under- 

 taken by the writer as Director of the International School of 

 American Archseolofry and Ethnology, Mexico, in the winter of 

 1913-14. It was due to a suo;o;estion from Seilor Don Manuel Gamio, 

 Director of Antiquities, that the site in question was selected, and it 

 was due to his official permission and to his courtesy and aid that the 

 work was carried on. To his brother, Senor Rodrigo Gamio, Mexican 

 Fellow of the School, my thanks are due for long- continued and 

 faithful assistance in the excavation, and to Clarence L. Hay, Esq., 

 Harvard Fellow, I owe many valuable sugoestions in carrying on 

 the work, and I also thank him for aiding me in the general super- 

 vision of the excavations. Dr. Herbert J. Spinden has given me some 

 suggestions regarding the nomenclature of the pottery classification.
