I have put together the following account of a recent journey made for the Siamese Government to the Mekong valley, chiefly for the reason that at the present moment, when the French have "rectified" their boundaries on the north and east of Siam to the extent of some 85,000 square miles, more interest than usual will probably be felt in the character of the country and the people, of whom there are not too many reliable accounts to be found. At the same time, I feel very strongly that there are others whose descriptions will be far more valuable than my own, owing to their longer residence in the country, and the greater extent of their explorations. I refer especially to Messrs. McCarthy, Archer, and Beckett, who have done difficult and extensive work in all parts of Siam and the Laos states; and there is certainly no European, and probably no Siamese, that knows so much of the configuration of the north-east as does Mr. McCarthy, who, carried on by an apparently deep love of jungle-life, has aroused the admiration of the Siamese and Laos at Luang Prabang by his hardihood and energy, and the results of whose work were a constant source of admiration to me, as I went on and saw the wildness and difficulty of the country.

The object of my journey was primarily the examination, for the Siamese Government, of a supposed very rich deposit of gems (rubies and sapphires), lately discovered on the left bank of the Mekong, opposite Chieng Kong. My orders were to return by Luang Prabang, Nongkhai, and Khorat, and to visit and report on all mineral deposits of which I could get information, gathering all geological data which were possible. The time allowed was six months, and I was not to leave the general line of march prescribed by more than 60 miles. I need hardly say—and every one who knows what jungle-travelling is will understand—that my programme, to be thoroughly carried through over the large extent of country marked out, might well occupy six years instead of months; and that such a hurried exploration in a country covered densely with forest—which, next perhaps to snow, is the greatest enemy to the science of geology—could not but be unsatisfactory to one's self.
