Some of these Sulu people, till lately fierce sea-rovers, get baptized now and then; but, says Foreman, "they appeared to be as much Christian as I was Mussulman[557]." They keep their harems all the same, and when asked how many gods there are, answer "four," presumably Allah plus the Athanasian Trinity. So the Ba-Fiots of Angola add crucifying to their "penal code," and so in King M'tesa's time the Baganda scrupulously kept two weekly holidays, the Mussulman Friday, and the Christian Sunday. Lofty creeds superimposed too rapidly on primitive beliefs are apt to get "mixed"; they need time to become assimilated. That in the aborigines of Formosa are represented both Mongol (proto-Malayan) and Indonesian elements may now probably be accepted as an established fact. The long-standing reports of Negritoes also, like the Philippine Aeta, have never been confirmed, and may be dismissed from the present consideration. Probably five-sixths of the whole population are Chinese immigrants, amongst whom are a large number of Hakkas and Hok-los from the provinces of Fo-Kien and Kwang-tung[558]. They occupy all the cultivated western lowlands, which from the ethnological standpoint may be regarded as a seaward outpost of the Chinese mainland. The rest of the island, that is, the central highlands and precipitous eastern slopes, may similarly be looked on as a north-eastern outpost of Malaysia, being almost exclusively held by Indonesian and Malayan aborigines from Malaysia (especially the Philippines), with possibly some early intruders both from Polynesia and from the north (Japan). All are classed by the Chinese settlers after their usual fashion in three social divisions:-- 1. The _Pepohwans_ of the plains, who although called "Barbarians," are sedentary agriculturists and quite as civilised as their Chinese neighbours themselves, with whom they are gradually merging in a single ethnical group. The Pepohwans are described by P. Ibis as a fine race, very tall, and "fetishists," though the mysterious rites are left to the women. Their national feasts, dances, and other usages forcibly recall those of the Micronesians and Polynesians. They may therefore, perhaps, be regarded as early immigrants from the South Sea Islands, distinct in every respect from the true aborigines. 2. The _Sekhwans_, "Tame Savages[559]," who are also settled agriculturists, subject to the Chinese (since 1895 to the Japanese) administration, but physically distinct from all the other Formosans--light complexion, large mouth, thick lips, remarkably long and prominent teeth, weak constitution. P. Ibis suspects a strain of Dutch blood dating from the seventeenth century. This is confirmed by the old books and other curious documents found amongst them, which have given rise to so much speculation, and, it may be added, some mystification, regarding a peculiar writing system and a literature formerly current amongst the Formosan aborigines[560].
