Note 4 — Chapter XX · The Exploration of Non-Christian Territory
Reading edition
During the years covered by this hasty narrative, I also made trips to the territory of the wild men in Mindoro, Palawan, and Mindanao, as opportunity offered. In Spanish days I had lived among the Moros and had visited the mountains of Negros and Panay and seen something of the wild men living there, so that I finally gained a fairly comprehensive knowledge of the non-Christian tribes of the Philippines, having seen representatives of nearly all of them,4 and lived for longer or shorter periods among all except some of the more unimportant peoples in the interior of Mindanao.
