Lawrence Dundas, A wandering student in the Far East… (1908)
“ That part of the Mekong which stood athwart my course must be considered, as M. Vivien St Martin points out, "not as a trade route, but as a barrier to commerce, since each crossing of the river necessitates a descent and an ascent of from 3300 feet to 4400 feet each." Having negotiated the descent and the ascent, I sought shelter and repose at the village of Shui Chai, built on the edge of a small cultivated basin high up on the range west of the river. ”
