Note 14 — Chapter XXIII · Corrigenda

And now for the real facts. At the time the census enumeration was made Apayao had been crossed by a white man only once and that more than a hundred years ago. Extensive portions of Ifugao and Bontoc, and the greater part of Kalinga, were unexplored, as were the interior of Mindoro and most of the interior of Palawan, to say nothing of immense regions in Mindanao. As a matter of fact, we do not to-day know with any accuracy the number of Mangyans in Mindoro, nor the number of Tagbanuas in Palawan, but it has been conclusively demonstrated that the latter were greatly underestimated by the census enumerators. There will be found in the appendix14 a table giving in detail the present accepted estimate of the non-Christian population of the islands, which numbers at least a million seventy thousand.
