Each vessel entering or leaving the harbor had to present a detailed manifest of cargo on board so that the government might maintain records of all goods imported and exported. Annual figures were to be compiled and submitted to the King for his study. Officials were also to keep extensive data on articles of primary necessity imported into the Province, including prices, shipping costs, place of origin, and quality. The statistics were to serve as guidelines for imports to prevent future shortages and to suggest the establishment of factories in Spain to manufacture the same goods. Steps were to be taken to expand shipbuilding facilities, and foreign construction techniques had to be studied to attain superiority over other nations in that field. Export figures were to be accumulated and analyzed, and the export of timber and tobacco was to be encouraged. The public was to be persuaded to abandon the pernicious practice of contraband.
