On the whole, the impression made upon me in my long and intimate dealings with the Mandáyas of the Kati'il, Manorigao, and Karága Rivers is that they are a brave, intelligent, clean, frank people that with proper handling might be brought to a high state of civilization. They are looked up to by Manóbos, Mañgguáñgans, Mansákas, and Debabáons as being a superior and more ancient race, and considered by the Bisáyas of the Agúsan Valley as a people of much more intelligence and fair-dealing than any other tribe. The Mandáyas consist of four branches:
THE TÁGUM BRANCH
These occupy the country from near the mouth of the Tágum to the confluence of the Sálug and Libagánon Rivers, or perhaps a little farther up both of the last-mentioned rivers. It is probable that the Debabáons farther up are the issue of Manóbos and Tágum Mandáyas.
THE AGÚSAN VALLEY BRANCH
It is usual for the people of the upper Agúsan from Gerona to Compostela to call themselves Mandáyas, but this appears to be due to a desire to be taken for Mandáyas. They have certainly absorbed a great deal of Mandáya culture and language, but, with the exception of Pilar and Tagusab, they are of heterogeneous descent--Mandáya, Manóbo, Mañgguáñgan, Debabáon, and Mansáka.
At the headwaters of the Agúsan and in the mountains that encircle that region live the Mandáyas that are the terror of Mandáyaland. They are called by the upper Agúsan people Kau-ó, which means the same as Tagakaólo, but are Mandáyas in every feature, physical, cultural, and linguistic.
