has been "manufactured" consciously.

But what is "native," and what is "derived"? The folklore of the
wild tribes--Negritos, Bagobos, Igorots--is in its way no more
"uncontaminated" than that of the Tagalogs, Pampangans, Zambals,
Pangasinans, Ilocanos, Bicols, and Visayans. The traditions of
these Christianized tribes present as survivals, adaptations,
modifications, fully as many puzzling and fascinating problems as
the popular lore of the Pagan peoples. It should be remembered,
that, no matter how wild and savage and isolated a tribe may be,
it is impossible to prove that there has been no contact of that
tribe with the outside civilized world. Conquest is not necessary
to the introduction of a story or belief. The crew of a Portuguese
trading-vessel with a genial narrator on board might conceivably be
a much more successful transmitting-medium than a thousand praos full
of brown warriors come to stay. Clearly the problem of analyzing and
tracing the story-literature of the Christianized tribes differs only
in degree from that connected with the Pagan tribes. In this volume
I have treated the problem entirely from the former point of view,
since there has been hitherto a tendency to neglect as of small value
the stories of the Christianized peoples. However, for illustrative
material I have drawn freely on works dealing with the non-Christian
tribes, particularly in the case of stories that appear to be native;
and I shall use the term "native" to mean merely "existent in the
Islands before the Spaniards went there."

In the notes, I have attempted to answer for some of the tales the
question as to what is native and what imported. I have not been
able to reach a decision in the case of all, because of a lack of
sufficient evidence. While the most obvious sources of importation
