Note 33 — Letters from Father Mateo Gisbert to the Reverend Fathers and Brothers of Veruela
Reading edition
The Manobos or Manuba (man-subá,33 “river dweller”) as is indicated by their name itself live near the rivers. They inhabit the valley of the Agúsan, which extends from Butúan to Oloagúsan. They live besides on the point of San Agustin on the southern shore of the bay of Malálag, and in the district of Cottabato, as may be seen in the ethnographical map, accompanying these letters, color no. 3.
