Root in the fall of 1899, to wit, the suppression of the Philippine insurrection, meant practically the subjugation of one big island, Luzón, containing half the population and one third of the total area of the archipelago, and six neighbouring small ones, the Visayan Islands." [331] Now as a matter of fact Mindanao is by no means Mohammedan. The Mohammedan Malays, called Moros, are found here and there along the western coast of the Zamboanga peninsula and along the southern coast of the island as far as Davao. They also extend far up the Cotabato River and occupy the Lake Lanao region, but that is all. The interior of the island is for the most part occupied by the members of a number of non-Christian, non-Mohammedan tribes, while its northern and eastern coasts are inhabited by Visayan Filipinos, of whom there are many in Zamboanga itself. While, as Blount says, the Moros took no part in the insurrection against the United States, the Visayans of Mindanao did, and we had some lively tussles with them in Misamis and in Surigao. It is indeed unthinkable that we should turn Mindanao over to the Moros. Abandonment of it by us would in the end result in this, as they would take possession of the entire island in the course of time. Neither the other wild tribes nor the Filipinos could stand against them. I heartily agree with the conclusion that we must retain this island for many years before we can settle the problems which it presents. It is further true that we might retain it and still grant independence to the remainder of the Philippine Archipelago, but if we are to eliminate Mindanao from consideration because the Filipinos have no right to control the Moros, of whom there are in reality only about a hundred and fifty-four thousand [332] on the island, and could not if they would, what about Luzón, where there are in reality no less than four hundred and sixty thousand non-Christians, [333] many of whom, like the Ifugaos, Bontoc Igorots, Kalingas and wild Tingians, are fierce fighters and practically all of whom are bitterly opposed to the thought of possible ultimate domination by Filipinos, while most of them welcome American rule? Have the Filipinos any more moral right to control them than they have to control the Moros? Could they control them if they would? And has the most uncompromising advocate of the consent of the governed principle "a leg to stand on" in the one case if he lacks it in the other? The Filipino politicians are not ready to admit that Filipinos could not satisfactorily govern Moros and have even alleged that they did so govern them during the period now under discussion. Let us examine the facts. Aguinaldo attempted to enter into negotiations with the Sultan of Joló, addressing him as his "great and powerful brother," [334] but this brother does not seem to have received his advances with enthusiasm, and the other brothers proceeded to do things to the Filipinos at the first opportunity.
