Note 1 — Introduction
Reading edition
The present population of the Philippine Islands is about 10,000,000. Notwithstanding, there are vast stretches of unoccupied lowlands. At the coming of the Spaniards the population of the tribes that now are Christian has been estimated at 500,000. These second Malay immigrants undoubtedly gained the principal part of their livelihood from agriculture, for which they needed little land. Why, then, is it hypothesized that any immigration drove another to the mountains? My own belief is that the first immigrants went to the mountains of their own volition for the reason that they had been a mountain people and a terrace-building people in their former home.
