The Igorots, Ifugaos and Kalingas are adepts in the use of irrigation water, and know how to terrace the steepest mountain sides so as to employ it advantageously wherever it is available. The giving of help in running main irrigation ditches through rock has been especially appreciated by them. The money which we expend for this purpose goes for the establishment of proper grade lines, the providing of necessary supervision and the purchase of explosives and tools for rock work. The people concerned are more than glad to contribute all necessary labour free of charge. Would the Filipinos continue to make funds available for such improvements in the wild man's country? A thousand times no! Before any one disputes me, let him show one instance where they have done any such thing in any one of the very numerous provinces where the expenditure of funds for non-Christians is under their control. In dealing with tribes which have been accustomed to live by families, or small groups of families, and to select very inaccessible places for their homes, it is of course necessary to persuade them to live in larger groups and in reasonably accessible places before much progress can be made toward improving their condition. This is usually not a very difficult task if one goes about it in the right way. In Bukidnon, for instance, where we are still bringing people down from the tree-tops, in which they and some of their ancestors have lived for centuries, and settling them in well-ordered and beautifully kept villages, when new arrivals come in to inspect the towns and interrogate me as to the conditions under which they may take up residence there, I often have conversations like this:-- "What about this life in town?" "Look around and see for yourself. Talk with the people and hear what they have to say about it. They will tell you whether they like it or not, and why." "But what do I have to do if I wish to live in town?" "A piece of ground will be assigned to you and on it you must build a decent house like those you see. This house is for you and your family, not for me. I come here only once or twice a year and at the most stay over one night, so I do not need your house. The lieutenant-governor does not need it. When he comes he stays at the presidencia. He will not let any one take it away from you." "Very well. What else?" "You will have to build a good, tight fence around the lot given you and keep your domestic animals inside it. You must also clean it up thoroughly, removing all vegetation and filling all the low places so that water cannot stand in them. Then you must keep it clean." "What is the use of that?" "The búsaos [60] who cause sickness do not like clean places and stay away from them." "I never heard of that." "Ask the people who have tried keeping their yards clean, and they will tell you that it is true." "Well, what else?"
