Note applicable to all the Tables in Section ll. —The order above prescribed in which ships are to be scrapped is in accordance with their age. It is understood that when replacement begins according to the above tables the order of scrapping in the case of the ships of each of the contracting Powers may be varied at its option ; provided, however, that such Power shall scrap in each year the number of ships above stated. PART 4.—DEFINITIONS. For the purposes of the present Treaty the, following expressions are to be understood in the sense defined in this Part:— Capital Ship. A capital ship, in the case of ships hereafter built, is defined as a vessel-of-war (not an aircraftcarrier) whose displacement exceeds 10,000 tons (10,1.60 metric tons) standard displacement, or which carries a gun with a calibre exceeding 8 inches (203 millimetres). AIRCRAFT-CA RRIEI!. An aircraft-carrier is defined as a vessel-of-war, with a displacement in. excess of 10,000 tons (10,160 metric tons) standard displacement, designed for the specific and exclusive purpose of carrying aircraft. It must be so constructed that aircraft can be. launched therefrom and landed thereon, and not designed and constructed for carrying a more powerful armament than that allowed to it under Article IX or Article X, as the case may be. Standard Displacement. The standard ■ displacement of a ship is the displacement of the ship complete, fully manned, engined, and equipped ready for sea, including all armament and ammunition, equipment, outfit, provisions and fresh water for crew, miscellaneous stores and. implements of every description that are intended to be carried in war, but without fuel or reserve feed-water on board. The word " ton " in the present Treaty, except in the expression " metric tons," shall be understood to mean the ton of 2,240 pounds (1,016 kilos). Vessels now completed shall retain their present ratings of displacement tonnage in accordance with their national system of measurement. However, a Power expressing displacement in metric tons shall be considered for the application of the present Treaty as owning only the equivalent displacement in tons of 2,240 pounds. A vessel completed hereafter shall be rated at its displacement tonnage when in the standard condition defined herein. CHAPTER lII.—MISCELLANEOUS PROVISIONS. Article XXI.

In view of possible technical and scientific developments, the United States, after consultation with the other contracting Powers, shall arrange for a conference, of all the contracting Powers, which shall convene as soon as possible after the expiration of eight years from the coming into force of the present Treaty, to consider what changes, if any, in the Treaty may be necessary to mee+- such developments. Article XXII. Whenever any contracting Power shall become engaged in a war which in its opinion affects the naval defence of its national security, such Power may, after notice to the, other contracting Powers, suspend for the period of hostilities'its obligations under the present Treaty, other than those under Articles XIII and XVII; provided that such Power shall notify the other contracting Powers that the emergency is of such a character as to require such suspension. The remaining contracting Powers shall in such case consult together with a view to agreement as to what temporary modifications, if any, should be made in the Treaty as between themselves. Should such consultation not produce agreement, duly made in accordance with the constitutional methods of the respective Powers, any one of said contracting Powers may, by giving notice to the other contracting Powers, suspend for the period of hostilities its obligations under the present Treaty, other than those under Articles XIII and XVII. On the cessation of hostilities the contracting Powers will meet in conference to consider what modifications, if any, should be, made in the provisions of the present Treaty. Article XXIII.
