Note 59 — Chapter IX · (continued 2)

Of the tribes of Mindanao, Census of Philippines, i, p. 462, says: “Going eastward in Mindanao and passing by the central lake region, which is inhabited entirely by Lanao Moros, we come to other tribes, which, so far as I have seen, differ in no essential from the Subanon.... Around the headwaters of the Rio Grande de Mindanao they are called Manobo. South of the Rio Grande they are called Tiruray, Bilan, Manobo, and other names. The reason for the use of these different terms is not satisfactorily explained. There are doubtless changes of dialect between them comparable to the changes we find among the Igorots in northern Luzón, but I believe it is hardly justifiable to break up into separate tribes or divisions a population so thoroughly homogeneous as these pagans of Mindanao appear to be.”
