Note 1 — Domesticated Natives—Origin—Character

There is good reason to surmise that, at some remote period, these Islands and the Islands of Formosa and Borneo were united, and possibly also they conjointly formed a part of the Asiatic mainland. Many of the islets are mere coral reefs, and some of the larger islands are so distinctly of coral formation that, regarded together with the numerous volcanic evidences, one is induced to believe that the Philippine Archipelago is the result of a stupendous upheaval by volcanic action.1 At least it seems apparent that no autochthonous population existed on these lands in their island form. The first settlers were probably the Aetas, called also Negritos and Balugas, who may have drifted northwards from New Guinea and have been carried by the strong currents through the San Bernadino Straits and round Punta Santiago until they reached the still waters in the neighbourhood of Corregidor Island, whilst others were carried westwards to the tranquil Sulu Sea, and travelling thence northwards would have settled on the Island of Negros. It is a fact that for over a century after the Spanish conquest, Negros Island had no other inhabitants but these mountaineers and escaped criminals from other islands.
