Meyer, [8] who has given the subject much study and has conducted personal investigations on the field, states that "although at the time of the arrival of the Spaniards in the country, and probably long before, the Negritos were in process of being driven back by the Malays, yet it appears certain that their numbers were then larger, for they were feared by their neighbors, which is now only exceptionally the case." Of the vast amount of material that has been written during the past century on the Negritos of the Philippines a considerable portion can not be taken authoritatively. Exceptions should be made of the writings of Meyer, Montano, Marche, and Blumentritt. A large part of the writings on the Philippine Negritos have to do with their distribution and numbers, since no one has made an extended study of them on the spot, except Meyer, whose work (consisting of twelve chapters and published in Volume IX of the Publications of the Royal Ethnographical Museum of Dresden, 1893) I regret not to have seen. Two chapters of this work on the distribution of the Negritos, republished in 1899, form the most recent and most nearly correct exposition of this subject. Meyer summarizes as follows: It may be regarded as proved with certainty that Negritos are found in Luzon, Alabat, Corregidor, Panay, Tablas, Negros, Cebu, northeast Mindanao, and Palawan. It is questionable whether they occur in Guimaras, Mindoro, and the Calamianes. This statement would be more nearly correct if Corregidor and Cebu were placed in the second list and Guimaras in the first. In this paper it is possible, by reason of special investigations, to give more reliable and detailed information on this subject than any yet published. Present Distribution in the Philippines [9] In Luzon This paper concerns itself chiefly with the Zambales Negritos whose distribution in Zambales and the contiguous Provinces of Bataan, Pampanga, and Tarlac is treated in detail in the following chapter. But Negritos of more or less pure blood, known variously as Aeta, Agta, Baluga, Dumagat, etc., are found in at least eleven other provinces of Luzon. Beginning with the southern end of the island there are a very few Negritos in the Province of Sorsogon. They are found generally living among the Bicol population and do not run wild in the woods; they have probably drifted down from the neighboring Province of Albay. According to a report submitted by the governor of Sorsogon there are a few of these Negritos in Bacon and Bulusan, and four families containing Negrito blood are on the Island of Batang near Gabat. Eight pueblos of Albay report altogether as many as 800 Negritos, known locally as "Agta." It is not likely any of them are of pure blood. In all except three of the towns they are servants in Bicol houses, but Malinao, Bacacay, and Tabaco report wandering groups in the mountains.
