Dalton, Ethnology of Bengal, pp. 196 et seq. W. Crooke (Journal of the Anthropological Institute, p. 243, 1899) also refers to the annual harvest-tree dance and saturnalia, and its association with the seasonal period for marriage. We find a similar phenomenon in the Malay Peninsula: "In former days, at harvest-time, the Jakuns kept an annual festival, at which, the entire settlement having been called together, fermented liquor, brewed from jungle fruits, was drunk; and to the accompaniments of strains of their rude and incondite music, both sexes, crowning themselves with fragrant leaves and flowers, indulged in bouts of singing and dancing, which grew gradually wilder throughout the night, and terminated in a strange kind of sexual orgie." (W. W. Skeat, "The Wild Tribes of the Malay Peninsula," Journal of the Anthropological Institute, 1902, p. 133.)
