They occupy the following rivers with their tributaries: the Kati'il, the Baganga, the Mano-rigao, the Karága, the Manai, the Kasaúman, and the upper reaches of the Mati. There are several small rivers between the Kasaúman and the Mati, the upper parts of all which, I think, are occupied by Mandáyas.
THE GULF OF DAVAO BRANCH
These occupy the upper reaches of all the rivers on the east side of the gulf of Davao, from Sumlug to the mouth of the Hijo River whose source is near that of the Agúsan and whose Mandáyas are famous in Mandáyaland.
THE MOROS
Moros or people with a preponderance of Moro blood and culture occupy the coast towns on the eastern and northern sides of the gulf from Sumlug to the mouth of the Tágum. Of course they have other settlements on the north and west sides of the gulf.
In Mati and its vicinity, I believe there are a comparatively large number of Moros or Mohammedanized Mandáyas.
