ADDITIONAL TREATY BETWEEN PRANCE AND SIAM
281
The frontier follows the crest of the Pnom-Krevimli in a northerly direction aa
far as Pnom-Thom, which is situated on the main line of the watershed, between
the rivers which flow towards the gulf of Siam, and those which flow towards the Great
Lake. From Pnom-Thom, the frontier follows at first in a north-westerly direction,
then in a northerly direction, the actual frontier between the Province of Battambang
on the one hand, and that of Chantaboum and Kratt on the other, as far as the point
where this frontier joins the river called Nam-Sai. It then follows the course of this
river as far as its confluence with the River of Sisophon, and the latter river to a
point situated 10 kilom. below the town of Aranh. Lastly, from this latter point, it
continues in a straight line to a point situated on the Dang-Reck, halfway between
the passes called Chong-Ta-Koh and Chong-Sa-Met. It is understood that this latter
line must leave in Siamese territory the direct route between Aranh and Chong-Ta-Koh.
From the above-mentioned point, situated on the crest of Dang-Reck, the
frontier follows the watershed between the basin of the Great Lake and the Mekong
on the one side, and the basin of the Nam-Moun on the other, and touches the*
Mekong below Pak-Moun, at the mouth of the Huei-Doue, in conformity with the
sketch map adopted by the last Commission of Delimitation on the 18th January, 1907.
Clause II.—From the side of Luang-Prabang, the frontier quits the Mekong, in
the south, at the mouth of the H am-Huong, and follows the thalweg of that river as-
far as its source which is situated at the Phu-Khao-Mieng. Thence the frontier
follows the watershed between the Mekong and the Menam and tern:mates in the
Mekong, at the point called Keng-Pha-Dai, in conformity with the sketch map-
adopted by the last Commission of Delimitation of the 16th January, 1906.
Clause III.—The Commission of Delimitation arranged for in Article IV. of
the Treaty of to-day’s date shall determine and trace if necessary, on the spot, that
portion of the frontier which is described in Clause I. of the present Protocol.
If, in the course of the work of delimitation, the French Government should wish
to obtain a rectification of the frontier with a view to substituting natural lines for
conventional lines, this rectification cannot be made, in any case, to the detriment
of the Siamese Government.
In witness whereof the respective Plenipotentiaries have signed the present
Protocol, and have affixed their seals.
