WATER TRANSPORTATION 533 OCEAN SHIPPING SUMMARY.—The tonnage of the American merchant marine declined in 1925 compared with 1924, but nevertheless was two and one-fourth times as great as before the war, The loss appeared only in the tonnage engaged in foreign ‘rade, which was still about nine times as great as the 1910-1914 average. The idle steam shipping in world ports decreased slightly from 5,891,000 gross tons on January 1, 1925, to 5,845,000 gross tons on January 1, 1926, the United States accounting for a little over 70 per cent of the total idie on the latter date. A decline occurred in the amount of tonnage under construction in the world as a whole, the total for 1925 being 2,070,000 gross tons compared with 2,470,000 in 1924. The United States, however, with 105.000 tons under construction showed a gain of 47,000 tons. } Entrances at United States ports of vessels engaged in foreign trade totaled 89,378,000 net tons, a record figure, more than 1,000,000 tons greater than in 1924, and 49 per cent over the 1910-1914 average. Of these, 73 per cent (ton= nage) carried cargo, compared with 71 per cent in 1924. American vessels represented 40.3 per cent of the total entrances as against 43.4 per cent in 1924. Clearances from United States Ports aggregated 1,318,000 tons more than in 1924. Vessels with cargo represented 771% per cent of the total, practically the same proportion as in 1924. The weight of cargo exported was somewhat less but hat of cargo imported somewhat greater in 1925 than in 1924, Table 22. —Summary of Major Statistics of Shipping [Thousands of tons] (tem American merchant marine: Total gross A On Tonnage in foreign trade.........

Calendar year 1915 only, ' Per cent increass over 181A. Tonnage of World’s Merchant Marine. The world’s merchant marine, as measured in terms of steel steam and motor vessels (not counting Great Lakes tonnage in America and tonnage of Canadian lakes) was 58.785.000 tons on June 30, 1925. 1 General note as to units of measurement. — Cargo tonnage’ represents weight of cargo actually loaded, unloaded, or carried in either long tons (2,240 Pounds) or short tons (2,000 pounds) as specified. All other sonnage figures refer to capacity of vessels, The terms gross and net tonnage refer to space measurement, 100 cubic feet being called 1 ton. Gross tonnage is the capacity of the entire space within the frames and the ceiling of the hull, together with those closed-in spaces above deck available for cargo, storage, passengers or crew, With certain minor exemptions. Net or registered tonnage is what remains aiter dedueting from the gross tonnage the spaces occupied by the propelling machinery (including allowance for fuel), crew quarters, naster’s cabin, and navigation spaces. It represents substantially space available for cargo and passengers, I'he net tonnage capacity of a ship recorded as “‘entered with cargo” may bear little relation to the actual weight of the caren.
