A full and first hand account of an eighteen months' search in south eastern Tibet for the source of the Salween, the black river of Tibet, which won the author the Murchison Grant of the Royal Geographical Society. With one other Englishman and three faithful (and quite enchanting) natives and a good stock of supplies, he collected specimens of insect life, distributed medical care to the very friendly residents and gives a record of their daily progress. Across 3,000 miles of unexplored territory, there were many oddities to be seen, minor discomforts rather than major calamities, to be endured, and plenty of good anecdotes. None of the he-man-big-explorer stuff, and nice humorous touches throughout. The matter-of-fact-ness is appealing. Pick your special customers for this.
