NUMBER.
The exact number who fall under this classification is not known, Governor Bolton, who was intimately acquainted with the wild tribes of the District, estimated their number at sixty-five hundred, but this count did not include the sub-division here given as Obo. One enumeration, made by a Jesuit missionary, places the population at fifteen thousand, while the Government report of 1900 gives them eighteen thousand four hundred. The latter estimates are certainly excessive. It is probable that they were determined by compiling the population of villages reported to exist in the interior.
The wilder members of this tribe are, to a certain extent, migratory, moving their villages from one location to another according to the demands of their mode of agriculture. Their rice fields are made in mountain-side clearings, and as the ever present cogon grass[1] begins to invade the open land they substitute sweet potatoes or hemp. In time even these lusty plants give way to the rank grass, and the people find it easier to make new clearings in the forest than to combat the pest with the primitive tools at their command. This results in some new fields each year, and when these are at too great a distance from the dwellings the old settlements are abandoned and new ones formed at more convenient locations.

It is probable that the total number belonging to this tribe does not exceed ten thousand persons.
