As many as sixteen towns of Cagayan report Negritos to the total number of about 2,500. They are known commonly as "Atta," but in the pueblo of Baggao there are three groups known locally as "Atta," "Diango," and "Paranan." They have been described by natives of Baggao as being very similar to the ordinary Filipinos in physical characteristics except that they are darker in color and have bushy hair. Their only weapons are the bow and arrow. Their social status is in every way like that of the Negritos as distinguished from the industrious mountain. Malayans of northern Luzon. Yet future investigations may not associate these robust and warlike tribes with the weak, shirking Negritos. Negritos of pure type have not so far been reported from Cagayan. At only two places in the western half of northern Luzon have Negritos been observed. There is a small group near Piddig, Ilokos Norte, and a wandering band of about thirty-five in the mountains between Villavieja, Abra Province, and Santa Maria, Ilokos Sur Province, from both of which towns they have been reported. It is but a question of time until no trace of them will be left in this region so thickly populated with stronger mountain peoples. In the Southern Islands Although Negritos were reported by the early Spanish writers to be especially numerous in some of the southern islands, probably more of them are found on Luzon than on all the other islands in the Archipelago. Besides Luzon, the only large islands inhabited by them at present are Panay, Negros, Mindanao, and Paragua, but some of the smaller islands, as Tablas and Guimaras, have them. Negritos of pure blood have not been reported from Mindoro, but only the half-breed Manguian, who belong in a group to themselves. It is questionable whether the unknown interior will produce pure types, though it is frequently reported that there are Negritos in the interior.
