Notes of a Journey on the Upper Mekong, Siam — A Reader’s Guide

The Rapids as Character

Smyth devotes considerable attention to the Mekong's rapids, but his descriptions are anything but generic. He distinguishes between two types: those caused by rough sloping rock ridges, as on the Nam Oo, and those in the main river from narrowing channels and deep obstructions. In the latter, he notes, the term "rapid" is often a misnomer, because whirlpools, back eddies, and counter currents can drag a boat sideways or upstream. His account of a boat spending "several minutes in passing down a hundred yards" despite every hand straining at the oars conveys the physical struggle without melodrama. These passages ground the reader in the specific hazards of Mekong navigation.

Evening Concerts and Local Voices

At Luang Prabang, Smyth records the evening sounds: the kans (a type of mouth organ) passing homeward, bugles, drums, and the calls of nok poots (birds) that mark the hours. He describes impromptu concerts where a singer improvises verses on a subject given by a young woman, to general laughter and approbation. Smyth admits he and his party "failed signally to understand the words" because the local dialect differed from that of Nan. This honest limitation—rather than pretending to full comprehension—adds credibility. He also notes that the Laos of Luang Prabang keep late hours, a small cultural detail that emerges from his observations of their music and social habits.

Geologist among Gems and Government

The primary object of Smyth's journey was to examine a gem deposit, but the excerpts reveal more about the practical challenges of his work. He mentions exchanging visits with the Chow Luang and Chow Huanar (local rulers), finding them "pleasant, open-countenanced men" who became jovial after a second meeting. The latter helped him considerably. Smyth's role as a government geologist required diplomacy as much as science. He also notes the difficulty of geological survey in forested terrain, where outcrops are scarce. These details give a sense of the day-to-day reality of a colonial scientific expedition, with its mix of social negotiation and physical endurance.

The Nam Oo Expedition

One of Smyth's longest excursions from Luang Prabang was up the Nam Oo River to Muang Ngoi. He describes the scenery as "very fine," with limestone peaks and dense forest overhanging the river. But the rapids were "furious" and dangerous due to shallow water and sunken rocks. He contrasts these rapids with those of the Mekong: the Nam Oo's are caused by rough sloping rock ridges, while the Mekong's are from channel narrowing and deep obstructions. This comparative approach shows his geological eye at work. The expedition also yields a glimpse of local life, though the excerpts focus on the physical journey rather than settlements.

Smyth's narrative moves between the specific and the general: a particular rapid, a single evening's concert, a ruler's helpfulness. Readers should attend to these concrete details rather than expecting a comprehensive survey. The book's value lies in its unvarnished record of what one geologist saw and heard during a hurried mission—a snapshot of the Upper Mekong at a moment of political transition, before the boundaries were fully fixed.

Sometimes I think of Smyth’s Laos, the way he mapped rapids while empires redrew borders, and it makes me wonder about other northern journeys taken for work, not glory. The Wild North Land The Story of a Winter Journey with Dogs across Northern North America — Inside the Classic has that same quiet patience, the sense of a man simply noting what the cold gives him. Both feel like letters from another century, left on a shelf for someone slow to find them.
