The second great stage of culture, which we may call, though somewhat inaccurately, the Malayo-Polynesian, offers a radically different picture. To a certain extent, the relation between tribal organization and external culture is here the reverse of that which obtains in the Australian world. In Australia, we find a primitive culture alongside of a highly developed tribal organization; in the Malayo-Polynesian region, there is a fairly well developed culture, but a tribal organization which is partly in a state of dissolution and partly in transition to further political and social institutions, including the separation of classes and the rulership of chiefs. Evidently these latter conditions are the result of extensive racial fusion, which is incomparably greater in the Malayo-Polynesian region than in Australia. True, we no longer harbour the delusion that Australia is inhabited by a uniform population. It also has been subject to great waves of immigration, particularly from New Guinea, from whence came the Papuans, one of the races which itself attained to the Malayo-Polynesian level of culture. Naturally the Papuan influx affected chiefly the northern part of Central Australia. The Tasmanian tribe, now extinct, was probably a remnant of the original Australian population. But migrations and racial fusions have caused even greater changes among those peoples who, culturally, must be classed with the Malayo-Polynesians. Here likewise there are many different levels, the lowest of which, as found among the Malayo-Polynesian mixed population, was yet but slightly higher, in some respects, than Australian culture, whereas the culture of the true Malays and Polynesians has already assumed a more advanced character. Ethnology is not yet entirely able to untangle the complicated problems connected with these racial fusions. Much less, of course, can we undertake to enter into these controversial points. We here call attention merely to certain main stages exhibited by the external culture of these peoples, quite aside from considerations of race and of tribal migrations. The Negritos and the Papuans of various parts of Melanesia possess a culture bordering on the primitive--indeed, they may even be characterized as primitive, since they possess characteristics of pretotemic society. Of these tribes, the Papuans of New Guinea and of the islands of the Torres Straits clearly manifest totemic characteristics, while yet possessing special racial traits that are exceptionally pronounced. They differ but little from primitive man, however, so far as concerns either their method of securing food or their dress, the latter of which is exceedingly scanty and is made, for the most part, of plant materials. But these peoples, just as do the Australians, have weapons indicative of battles and migrations; moreover, they exhibit also other marks of a somewhat developed culture. The Papuans are the first to change the
