In the Appendixes will be seen reprints of various documents, reports, quotations and letters of direct and significant bearing on the history of Sulu and Mindanao. They are arranged in chronological order and are intended to complete the record and description of important events in Moro history so as to throw light on the actual conditions of life among the Moros, the political motives of the interested powers, and the real state of affairs in Mindanao at the time of the Spanish evacuation. The source from which each article is derived is given in connection therewith. A considerable number of quotations or chapters have been taken from “The Philippine Islands,” by Blair and Robertson, for which special obligation is hereby expressed. Many of the official documents given could not be conveniently incorporated in the text of the history proper, and are herein published, probably for the first time. They include protocols, capitulations, official letters, decrees, and correspondence relative to Sulu obtained from the Division of Archives of the Philippine Islands. The originals of the copies can be seen in Spain in the Indies Archives.
Some liberty has been taken in correcting the spelling of geographical and other proper names in order to render the history uniform in its orthography and to avoid confusion and misconnection of events, persons, and places. The same system of orthography has been used here as that used and described in Part 1 of Volume IV, Ethnological Survey Publications. Diacritical signs to denote the long sounds of vowels have, however, been very rarely used. The Arabic “hamzat,” occurring in Moro words has been expressed by an apostrophe; while an inverted apostrophe has been used to represent the Arabic sound or character “ʿain,” the eighteenth letter of the Arabic alphabet. Annotations which occur in the original documents have generally been indicated by letters, while those made by the author are denoted by figures.
