The frontiers described by the present Treaty are traced on the one in a million maps attached to the present Treaty. In case of differences between the text and the map, the text will prevail. [See Introduction.]
Boundary Commissions, whose composition is or will be fixed in the present Treaty or in Treaties supplementary thereto, will have to trace these frontiers on the ground.
They shall have the power, not only of fixing those portions which are defined as "a line to be fixed on the ground," but also, if the Commission considers it necessary, of revising in matters of detail portions defined by administrative boundaries or otherwise. They shall endeavour in all cases to follow as nearly as possible the descriptions given in the Treaties, taking into account, as far as possible, administrative boundaries and local economic interests.
The decisions of the Commissions will be taken by a majority, and shall be binding on the parties concerned.
The expenses of the Boundary Commissions will be borne in equal shares by the parties concerned.
In so far as frontiers defined by a waterway are concerned, the phrases "course" or "channel" used in the descriptions of the present Treaty signify, as regards non-navigable rivers, the median line of the waterway or of its principal branch, and, as regards navigable rivers, the median line of the principal channel of navigation. It will rest with the Boundary Commissions provided for by the present Treaty to specify whether the frontier line shall follow any changes of the course or channel which may take place, or whether it shall be definitely fixed by the position of the course or channel at the time when the present Treaty comes into force.
In the absence of provisions to the contrary in the present Treaty, islands and islets Iying within three miles of the coast are included within the frontier of the coastal State.
The various States concerned undertake to furnish to the Commissions all documents necessary for their tasks, especially authentic copies of agreements fixing existing or old frontiers, all large scale maps in existence, geodetic data, surveys completed but unpublished, and information concerning the changes of frontier watercourses. The maps, geodetic data, and surveys, even if unpublished, which are in the possession of the Turkish authorities must be delivered at Constantinople, within thirty days from the coming into force of the present Treaty, to such representative of the Commissions concerned as may be appointed by the principal Allied Powers.
The States concerned also undertake to instruct the local authorities to communicate to the Commissions all documents, especially plans, cadastral and land books, and to furnish on demand all details regarding property, existing economic conditions, and other necessary information.
The various States interested undertake to give every assistance to the Boundary Commissions, whether directly or through local authorities, in everything that concerns transport, accommodation, labour, materials (sign-posts, boundary pillars) necessary for the accomplishment of their mission.
In particular the Turkish Government undertakes to furnish to the Principal Allied Powers such technical personnel as they may consider necessary to assist the Boundary Commissions in the accomplishment of their mission.
The various States interested undertake to safeguard the trigonometrical points, signals, posts or frontier marks erected by the Commissions.
The pillars will be placed so as to be intervisible; they will be numbered, and their position and their number will be noted on a cartographic document.
The protocols defining the boundary and the maps and documents attached thereto will be made out in triplicate, of which two copies will be forwarded to the Governments of the limitrophe States, and the third to the Government of the French Republic, which will deliver authentic copies to the Powers who sign the present Treaty.
