DAFLA HILLS, a tract of hilly country on the border of Assam, occupied by an independent tribe called Dafla. It forms part of the sub-Himalayan hills to the north of the Darrang and Lakhimpur districts, and is bounded on the west by the Bhareli river and on the east by the Ranganadi river. The Daflas are akin to both the hill Miris and the Abors. They are divided into exogamous clans claiming descent from the moon d' and sun 9 , extremely democratic in polity, but slave owners; burying their dead, whose spirits go to an underground world except in the case of unnatural deaths when they ascend to the sky. They use cane helmets, hide armour, long sword, spear and arrows poisoned with aconite. In 1872 the Daflas attacked a colony of their own tribesmen in British territory, which led in 1874 to a punitive ex pedition. Several small expeditions have since been made. The Daflas continually raid one another; occasional petty forays in the plains are made by malcontents and escaped slaves.
