Note 1 — Preface

My companions on these journeys were, in 1909, Mr. Clarence L. Hay; in 1911, Dr. Isaiah Bowman, Professor Harry Ward Foote, Dr. William G. Erving,Page ix Messrs. Kai Hendriksen, H. L. Tucker, and Paul B. Lanius; in 1912, Professor Herbert E. Gregory, Dr. George F. Eaton, Dr. Luther T. Nelson, Messrs. Albert H. Bumstead, E. C. Erdis, Kenneth C. Heald, Robert Stephenson, Paul Bestor, Osgood Hardy, and Joseph Little; and in 1915, Dr. David E. Ford, Messrs. O. F. Cook, Edmund Heller, E. C. Erdis, E. L. Anderson, Clarence F. Maynard, J. J. Hasbrouck, Osgood Hardy, Geoffrey W. Morkill, and G. Bruce Gilbert. To these, my comrades in enterprises which were not always free from discomfort or danger, I desire to acknowledge most fully my great obligations. In the following pages they will sometimes recognize their handiwork; at other times they may wonder why it has been overlooked. Perhaps in another volume, which is already under way and in which I hope to cover more particularly Machu Picchu1 and its vicinity, they will eventually find much of what cannot be told here.
