For the courtesies they showed me, and the assistance they afforded me during the long journey which is chronicled in this book, I am deeply indebted to many persons in many lands. I welcome this opportunity of expressing my gratitude to the Hon. Francis Burton Harrison, former Governor-General of the Philippine Islands, and to the Hon. Manuel Quezon, President of the Philippine Senate, for placing at my disposal the coastguard cutter Negros, on which I cruised upward of six thousand miles, as well as for countless other courtesies. Brigadier-General Ralph W. Jones, Warren H. Latimer, Esq., and Major Edwin C. Bopp shamefully neglected their personal affairs in order to make my journey comfortable and interesting. Dr. Edward C. Ernst, of the United States Quarantine Service at Manila, who served as volunteer surgeon of the expedition; John L. Hawkinson, Esq., the man behind the camera; James Rockwell, Esq., and Captain A. B. Galvez, commander of the Negros, by their unfailing tactfulness and good nature, did much to add to the success of the enterprise. I am likewise under the deepest obligations to Colonel Ole Waloe, commanding the Philippine [xii]Constabulary in Zamboanga; to the Hon. P. W. Rogers, Governor of Jolo; to Captain R. C. d'Oyley-John, formerly Chief Police Officer of Sandakan, British North Borneo; to M. de Haan, Resident at Samarinda, Dutch Borneo; and to his colleagues at Makassar, Singaradja, Kloeng-Kloeng, Surabaya, Djokjakarta, and Surakarta; to the Hon. John F. Jewell, American Consul-General at Batavia; to the Hon. Edwin N. Gunsaulus, American Consul-General at Singapore; to J. D. C. Rodgers, Esq., American Chargé d'Affaires at Bangkok; to his late Royal Highness the Crown Prince of Siam; to his Serene Highness Prince Traidos Prabandh, Siamese Under Secretary of State for Foreign Affairs; to his Serene Highness Colonel Prince Amoradhat, Chief of Intelligence of the Siamese Army, who constituted himself my guide and cicerone during our stay in his country; to the French Resident-Superior at Pnom-Penh; and to the other French officials who aided me during my travels in Indo-China. His Excellency J. J. Jusserand, French Ambassador at Washington and his Excellency Phya Prabha Karavongse, Siamese Minister at Washington, provided me with letters which obtained for me many facilities in French Indo-China and in Siam. Nor am I unappreciative of the many kindnesses shown me by James R. Bray, Esq., of New York City; by Austin Day Brixey, Esq., of Greenwich, Conn.; and by Dr. Eldon R. James, General Adviser to the Siamese Government. I also wish to acknowledge my indebtedness[xiii] to A. Cabaton, Esq., from whose extremely valuable study of Netherlands India I have drawn freely in describing the Dutch system of administration in the Insulinde. I have also obtained much valuable data from "Java and Her Neighbors" by A. C. Walcott, Esq., and from "The Kingdom of the Yellow Robe" by Ernest Young, Esq.
