The “Indian” has never seemed to me an abnormal factor, but rather a natural part of our society, for it is now nearly thirty years since I first associated with him in the Far West, and before that the Iroquois were familiar to me as a small boy. When I first went among the Western tribes, it was with the second Colorado River expedition of that gallant explorer and foremost student of Amerindian affairs, John Wesley Powell. His own works and the reports of the United States Bureau of Ethnology, of which he has so long been the head, and where he has gathered together so many eminent ethnologists and archæologists, have furnished me with much material. These reports form a fine library on Amerindian matters, and reflect great honour on Professor Powell who conceived the idea, and on Congress which has ungrudgingly supported it. A great and timely work has become established, which to private enterprise would have been next to impossible. Add to these the invaluable reports of the Smithsonian Institution and the memoirs and reports of the Peabody Museum and American Museum, and the student has before him a large fund of material without seeking farther. Then there are the brilliant works of Parkman, Brinton, Winsor, Bandelier, Putnam, Morgan, Schoolcraft, Prescott, Maudsley, Goodman, Wilson, Keane, and many others, with the huge production of H. H. Bancroft filling an important place. To all of these and to others I owe much, and I have intended in every case to give credit and references. Where these, in some cases, may not have been properly awarded, it is due to oversight and not to intention. My especial thanks are due to the Bureau of Ethnology for copies of all the reports, and for permission to utilise the illustrations contained in them, and to the American Museum, Archæological Institute, Field Columbian Museum, Peabody Museum, and Smithsonian Institution for similar generosity. I take pleasure also in acknowledging favours from Professor Putnam, Professor Powell, Professor Mason, Dr. McGee, Mr. Saville, Professor Seymour, Professor Langley, Mr. Bancroft, Professor Holmes, Dr. Baum, and others, and from Mr. E. H. Harriman the opportunity of visiting Alaska under the most favourable circumstances.
