Cecil Champain Lowis, The Tribes of Burma — The Was (1910)
“ The Was, including the Tai Loi, the En, the Hsen Hsum and other sub-tribes are a Trans-Salween hill-folk who, while clearly related to the Palaungs and the Yins, differ outwardly very considerably from them. The wild Was, of whom very little is known—their head-hunting propensities having secured them for the time being almost complete isolation—are all spirit worshippers and most of the tame Was are also non-Buddhists. ”
