These, together with the large number of printed books relating to America in the Congressional Library added to works in my possession, afforded an ample field for research.
I must express my appreciation of the courteous attentions of the accomplished Librarian of Congress, the Hon. A. R. Spofford, who together with his assistants did everything possible to facilitate my investigations. To the uniform and friendly interest which Mr. Spofford has manifested in my work, its successful completion is largely due. The substantial assistance which I received from the lamented Professor Joseph Henry—the record of whose kindly offices to his fellowmen can never be written—was invaluable to me. Besides placing the latest material at my disposal, he generously furnished most of the engravings in this work relating to the Mound-builders. Dr. Charles Rau, also of the Smithsonian Institution, has placed me under obligations for valued services. To Professor F. V. Hayden and to the painstaking offices of Mr. James Stevenson of the U. S. Geological and Geographical Survey of the Territories, I am indebted for the engravings as well as the sources of information relating to the Cliff-dwellers. The Hon. J. R. Bartlett, of Providence, R. I., with equal generosity has conferred like favors. Prof. F. W. Putnam, of the Peabody Museum of American Archæology and Ethnology at Cambridge, Mass., and his courteous assistants, Mr. Carr and Miss Smith, have provided me with valuable engravings and reports. Robert Clarke, Esq., and Mr. E. Gest, of Cincinnati, have also sent me engravings, and the former in particular has conferred frequent favors. Professor Ph. Valentini, of Albion, N. Y., with rare liberality, contributed interesting material relating to the Nahua Calendar. To Mr. Stephen Salisbury, Jr., of Worcester, Mass., Dr. R. J. Farquharson, of the Davenport Academy of Sciences, Rev. S. D. Peet, editor of the American Antiquarian, Cleveland, O., and to A. J. Conant, Esq., of St. Louis, Mo., I am indebted for the interest they have manifested, and for the material which they have brought to my attention.
Señor Orozco y Berra, of the City of Mexico, the distinguished author of the Geografía de las lenguas Mexicanas, has from time to time freely made important suggestions concerning some of the problems under consideration. To my friend the Rev. John W. Butler, of the City of Mexico, whose intelligent efforts in my behalf have been unremitting, I have special reason to be thankful. To all these generous friends I must be permitted here to express my deep sense of gratitude for their favors.
However, this pleasant task would be but half performed were I to omit the recognition of the unselfish friendship of the justly eminent author of the Native Races of the Pacific States. Mr. Hubert Howe Bancroft, whose rare erudition and breadth of thought are only surpassed by his magnanimity of nature and manliness of spirit, with a liberality which has scarce a parallel in authorship, sent me the majority of the engravings illustrative of the Maya and Nahua architecture and sculpture, used in the fourth volume of the Native Races. To this I may add the no less valuable encouragement which he so heartily gave during the progress of my work. Although some of my investigations were prosecuted before the publication of the Native Races, and though all of Mr. Bancroft’s sources relating to subjects which have received our mutual attention were before me and underwent a critical examination at my hands, it is but fair to state that the assistance which I derived from the Native Races has been of incalculable service in the preparation of this volume. If in any place I have omitted to render full credit to Mr. Bancroft, and to that imperishable monument of learning and industry, his great work, the omission has been due to inadvertence rather than intention. My obligations to Mr. Bancroft can never be discharged, nor can the kind attentions of Mr. Henry L. Oak, of the Bancroft Library, San Francisco, be forgotten.
Still my examination of the sources has not always led me to the same conclusions as were reached by the author of the Native Races. This may be owing to our different standpoints of observation, or possibly to an inappreciable bias in my own mind. It is, however, but justice to myself to say that this work has been prosecuted to its completion with the spirit of inquiry rather than of advocacy, and is the embodiment of an honest search for the truth.
