r does it belong to the Moro or to the so-called Christian people.

Different sections of China have rice terraces, and as early as the
thirteenth century Chinese merchants traded with the Philippines,
yet there is no record that they traded north of Manila -- where
terracing is alone found. Besides, the Chinese record of the early
commerce with the Islands -- written by Chao Jukua about 1250 it is
claimed -- specifically states that the natives of the Islands were
the merchants, taking the goods from the shore and trading them even
to other islands; the Chinese did not pass inland. Even though the
Chinaman brought phases of his culture to the Islands, it would not
have been agriculture, since he did not practice it here. Moreover,
whatever culture he did leave would not be found in the mountains
three or four days inland, while the people with whom he traded were
without the art. The same arguments hold against the Japanese as the
inspirers of Igorot terraces. There is no record that they traded
in the Islands as early as did the Chinese, and it is safe to say,
no matter when they were along the coasts of Luzon, that they never
penetrated several days into the mountains, among a wild, head-hunting
people, for what the agricultural Igorot had to sell.

The historic cultural movements in Malaysia have been not from the
north southward but from Sumatra and Java to the north and east; they
have followed the migrations of the people. It is believed that the
terrace-building culture of the Asiatic islands for the production
of mountain rice by irrigation during the dry season has drawn its
inspiration from one source, and that such terraces where found to-day
in Java, Lombok, Luzon, Formosa, and Japan are a survival of very early
culture which spread from the nest of the primitive Malayan stock and
left its marks along the way -- doubtless in other islands besides
these cited. If Japan, as has Formosa, had an early Malayan culture,
as will probably be proved in due time, one should not be surprised
to find old rice terraces in the mountains of Batanes Islands and
the Loo Choo Islands which lie between Luzon and Japan.

Building the sementera

It must be noted here that all Bontoc agricultural labors, from the
building of the sementera to the storing of the gathered harvest,
are accompanied by religious ceremonials. They are often elaborate,
and some occupy a week's time. These ceremonials are left out of this
