These laws offered construction and navigation subsidies, and also made provision for a widely extended postal service with increased postal subventions. The construction bounties were available for "any company composed of Japanese subjects exclusively as members and shareholders which shall establish a ship-yard conforming to the requirements of the Minister of State for Communications, and shall build ships." The rates were fixed as follows: for ships of over 1000 tons, twenty yen ($9.96) per gross ton; of over 700 and under 1000 tons, twelve yen; for engines built with ships, or in any other domestic dock-yard, with the consent of the Minister of Communications, five yen per horsepower. Japanese materials only were to be used, unless the Minister of Communications should give permission to use foreign materials. The navigation bounties were granted only for iron and steel ships owned exclusively by Japanese subjects, and plying between Japan and foreign ports. The rates in this class were: twenty-five sen (about 12-1/2 cents) per gross ton per thousand miles run for ships of 1000 tons steaming at ten knots an hour; ten per cent added for every additional 500 tons up to 6000 tons, and twenty per cent for every additional knot up to seventeen. Foreign-built ships less than five years old, owned by Japanese, were admitted to these bounties. The postal routes established were fifteen in number, calling for an annual expenditure of 4,964,404 yen (about $2,482,202) when in full operation. The payments for postal service were to be computed at the mileage rate given for navigation. Previous to this act the postal subventions had amounted annually to nine hundred and forty-five thousand yen in 1890 and 1891, and nine hundred and thirty thousand yen in the subsequent years.[FD] The effect of these laws was to stimulate overproduction. The _Nippon Yusen Kaisha_ ordered eighteen large freight steamers aggregating 88,000 tons. Other companies doubled and trebled their fleets.[FD] One result of the overproduction was the forcing down of freights. This, together with the business depression of 1898-99, brought losses to the shipping companies despite the large subsidies. The rapidly increasing amounts of the subsidies, too, were giving the Government concern. From a total of 1,027,275 yen in 1896 the sum expended annually had grown by 1899 to 5,846,956 yen. The total paid between 1896 and 1899 had amounted to 13,133,440 yen, about $6,566,720.[FD] Accordingly, in 1899 (March), a law was enacted modifying the system. The navigation bounties on foreign-built ships were reduced by half, while the subventions to the postal lines were fixed at certain yearly sums. A law of 1900 (February 23) extended the postal services. Under these laws the postal subventions reached a total of about 5,647,811 yen ($2,823,905) a year. Of this total the _Nippon Yusen Kaisha's_ was the lion's share,--4,299,861 yen, about $2,149,930.[FD]
