Induce Construction Dry-cargo: The provisions of the 1928 act failed to induce construction dry-cargo construction of dry-cargo ships, and the mail subsidies produced undesirable, if not scandalous, conditions. The Congressional investigations of 1935 resulted in a thorough overhaul of American policy for shipping subsidies, enacted into law as the Merchant Marine Act of 1936. Briefly, it provided for two types of subsidies, construction and operating. American owners meeting the conditions stipulated are paid the difference between their operating costs and those of their foreign competitors, the subsidy being subject to"capture to the extent that profits exceed 10 per
-nt, and the difference between foreign and .merican construction costs for comparable ships re paid by the government, provided foreign costs ,re not more than 50 per cent cheaper than American.
