Germany, in addition to most favored nation treatment on her railways, agrees to cooperate in the establishment of through ticket services for passengers and baggage; to ensure communication by rail between the allied, associated, and other States; to allow the construction or improvement within twenty-five years of such lines as necessary; and to conform her rolling stock to enable its incorporation in trains of the allied or associated powers. She also agrees to accept the denunciation of the St. Gothard convention if Switzerland and Italy so request, and temporarily to execute instructions as to the transport of troops and supplies and the establishment of postal and telegraphic service, as provided. CZECHO-SLOVAKIA [Sidenote: Access to the sea on north and south.] To assure Czecho-Slovakia access to the sea, special rights are given her both north and south. Toward the Adriatic she is permitted to run her own through trains to Fiume and Trieste. To the north, Germany is to lease her for ninety-nine years spaces in Hamburg and Stettin, the details to be worked out by a commission of three representing Czecho-Slovakia, Germany, and Great Britain. THE KIEL CANAL. [Sidenote: Open to ships of all nations at peace with Germany.] The Kiel Canal is to remain free and open to war and merchant ships of all nations at peace with Germany, subjects, goods and ships of all States are to be treated on terms of absolute equality, and no taxes to be imposed beyond those necessary for upkeep and improvement for which Germany is to be responsible. In case of violation of or disagreement as to those provisions, any State may appeal to the League of Nations, and may demand the appointment of an international commission. For preliminary hearing of complaints Germany shall establish a local authority at Kiel. SECTION XIII. INTERNATIONAL LABOR ORGANIZATION. [Sidenote: Permanent organization to be established.] Members of the League of Nations agree to establish a permanent organization to promote international adjustment of labor conditions, to consist of an annual international labor conference and an international labor office. The former is composed of four representatives of each State, two from the Government, and one each from the employers and the employed, each of them may vote individually. It will be a deliberative legislative body, its measures taking the form of draft conventions or recommendations for legislation, which, if passed by two-thirds vote, must be submitted to the lawmaking authority in every State participating. Each Government may either enact the terms into law; approve the principles, but modify them to local needs; leave the actual legislation in case of a Federal State to local legislatures; or reject the convention altogether without further obligation.
