In merchant vessels of 100 tons each and upward, less’ than half a million gross tons were launched in the world during that year or nearly a quarter of a million tons less than in the wear 1932. This is less, according. to Lloyd’s Register of Shipping, than at any time since before 1900 and the total output for 1933 was less than 15 per cent of .the figure = for 1913.
