Diamond, a photographer, the writer went in the latter part of April to Iba, Zambales, where a few days were spent in investigating the dialects of the Zambal people and in preparation for a trip to the interior. After a journey of 25 miles inland a camp was established near Tagiltil. During the three weeks we were there the camp was visited by about 700 Negritos, who came in from outlying settlements, often far back in the mountains; but, owing to the fact that most of them would remain only as long as they were fed, extended investigations had to be conducted largely among the residents of Tagiltil and the neighboring rancheria of Villar. From Tagiltil a trip was made southward behind the low mountain chain, which marks the limit of the plain, and through a hitherto unexplored territory, very broken and next to impassable except in the dry season. The trail, known only to Negritos and but little used, followed for the most part the beds of mountain streams. Four little rancherias were passed, the people of two of which had already visited us. A hard two-day trip brought us to Santa Fe, a barrio of San Marcelino. After a week with the Negritos at this place a trip was made toward the Pampanga boundary to Cabayan and Aglao, the former locality inhabited by several small groups of Negritos, the latter an isolated Ilokano barrio in and near which the Negritos live. A visit to the rancherias near Subig and Olongapo concluded the investigation. In all, more than a thousand Negritos were seen.
