other goods, which being imposed at so much a-pound of their supposed value, was called a poundage. In the forty-seventh year of Edward III., a duty of sixpence in the pound was imposed upon all goods exported and imported, except wools, wool-felts, leather, and wines which were subject to particular duties. In the fourteenth of Richard II., this duty was raised to one shilling in the pound; but, three years afterwards, it was again reduced to sixpence. It was raised to eightpence in the second year of Henry IV.; and, in the fourth of the same prince, to one shilling. From this time to the ninth year of William III., this duty continued at one shilling in the pound. The duties of tonnage and poundage were generally granted to the king by one and the same act of parliament, and were called the subsidy of tonnage and poundage. The subsidy of poundage having continued for so long a time at one shilling in the pound, or at five per cent., a subsidy came, in the language of the customs, to denote a general duty of this kind of five per cent. This subsidy, which is now called the old subsidy, still continues to be levied, according to the book of rates established by the twelfth of Charles II. The method of ascertaining, by a book of rates, the value of goods subject to this duty, is said to be older than the time of James I. The new subsidy, imposed by the ninth and tenth of William III., was an additional five per cent. upon the greater part of goods. The one-third and the two-third subsidy made up between them another five per cent. of which they were proportionable parts. The subsidy of 1747 made a fourth five per cent. upon the greater part of goods; and that of 1759, a fifth upon some particular sorts of goods. Besides those five subsidies, a great variety of other duties have occasionally been imposed upon particular sorts of goods, in order sometimes to relieve the exigencies of the state, and sometimes to regulate the trade of the country, according to the principles of the mercantile system.
That system has come gradually more and more into fashion. The old subsidy was imposed indifferently upon exportation, as well as importation. The four subsequent subsidies, as well as the other duties
