Cecil Champain Lowis, The Tribes of Burma — The Marus… (1910)
“ The Szis, who lie for the most part to the south of the Lashis, have been more assimilated into the pure Kachin population than the Lashis and Marus, and many of them have been looked upon in the past as belonging to the Lepai tribe. The Lashi country proper appears to lie south of the Nanwu Maru country near the lower reaches of the N'maikha, but like the Marus and Szis the Lashis are found here and there in the Myitkyina District. It is hard to form an idea of the strength of the tribes. ”
