According to tradition, the Tinguian were taught to plant and reap by a girl named Dayapán. This woman, who was an invalid, was one day bathing in the stream, when the great spirit Kaboniyan entered her body. He carried with him sugar-cane and unthreshed rice which he gave to the girl with explicit directions for its use. Likewise he taught her the details of the _Sayang_, the most important of the ceremonies. Dayapán followed instructions faithfully, and after the harvest and conclusion of the ceremony, she found herself to be completely cured. After that she taught others, and soon the Tinguian became prosperous farmers. [200] In Part I of this volume a reconstruction of the early life of this people was attempted from their mythology. The results seemed to indicate that the tales reflect a time before the Tinguian possessed terraced rice-fields, when domestic work animals were still unknown, and the horse had not yet been introduced into the land. But it was also noted that we are not justified in considering these as recent events. At this time, with the more complete data before us, it may be well to again subject the rice culture to careful scrutiny, in the hope that it may afford some clue as to the source from which it spread into this region. It is possible that the Tinguian may have brought it with them from their early home, which may be supposed to have been in southeastern Asia; they may have acquired it through contact with Chinese or Japanese traders, or through commercial relations with the islands to the south; or again it may have developed locally in the Tinguian, Igorot, and Ifugao territory. It should be noted at the outset that highly developed terrace cultivation is found in Japan and China to the north; in parts of Borneo, in the Nias archipelago, in Java, Bali, Lombok, Sumatra, Burma, and India proper, and it is probable that all within this broad belt developed from a single origin.
