of unmanufactured brass, of what is called gun-metal, bell-metal, and shroff-metal, still continues to be prohibited. Brass manufactures of all sorts may be exported duty free.

The exportation of the materials of manufacture, where it is not altogether prohibited, is in many cases subjected to considerable duties.

By the 8th George I, c. 15, the exportation of all goods, the produce or manufacture of Great Britain, upon which any duties had been imposed by former statutes, was rendered duty free. The following goods, however, were excepted: alum, lead, lead ore, tin, tanned leather, copperas, coals, wool cards, white woolen cloths, lapis calaminaris, skins of all sorts, glue, coney hair or wool, hares' wool, hair of all sorts, horses, and litharge of lead. If you expect horses, all these are either materials of manufacture, or incomplete manufactures (which may be considered as materials for still further manufacture), or instruments of trade. This statute leaves them subject to all the old duties which had ever been imposed upon them, the old subsidy and one per cent outwards.

By the same statute a great number of foreign drugs for dyers' use are exempted from all duties upon importation. Each of them, however, is afterwards subjected to a certain duty, not indeed a very heavy one, upon exportation. Our dyers, it seems, while they thought it for their interest to encourage the importation of those drugs, by an exemption from all duties, thought it likewise for their interest to throw some small discouragement upon their exportation. The avidity, however, which suggested this notable piece of mercantile ingenuity, most probably disappointed itself of its object. It necessarily taught the importers to be more careful than they might otherwise have been that their importation should not exceed what was necessary for the supply of the home market. The home market was at all times likely to be more scantily supplied; the commodities were at all times likely to be somewhat dearer there than they would have been had the exportation been rendered as free as the importation.

By the above-mentioned statute, gum senega, or gum arabic, being among the enumerated dyeing drugs, might be imported duty free. They were subjected, indeed, to a small poundage duty, amounting only to threepence in the hundredweight upon their re-exportation. France enjoyed, at that time, an exclusive trade to the country most productive of those drugs, that which lies in the neighbourhood of the Senegal; and the British market could not easily be supplied by the immediate importation of them from the place of growth. By the 25th George II, therefore, gum senega was allowed to be imported (contrary to the general dispositions of the Act of Navigation) from any part of Europe. As the law, however, did not mean to encourage this species of trade, so contrary to the general principles of the mercantile policy of England, it imposed a duty of ten shillings the hundredweight upon such importation, and no part of this duty was to be afterwards drawn back upon its exportation. The successful war which began in 1755 gave Great Britain the same exclusive trade to those countries which France had enjoyed before. Our manufacturers, as soon as the peace was made, endeavoured to avail themselves of this advantage, and to establish a monopoly in their own favour both against the growers and against the importers of this commodity. By the 5th George III, therefore, c. 37, the exportation of gum senega from his Majesty's dominions in Africa was confined to Great Britain, and was subjected to all the same restrictions, regulations, forfeitures, and penalties as that of the enumerated commodities of the British colonies in America and the West Indies. Its importation, indeed, was subjected to a small duty of sixpence the hundredweight, but its re-exportation was subjected to the enormous duty of one pound ten shillings the hundredweight. It was the intention of our manufacturers that the whole produce of those countries should be imported into Great Britain, and, in order that they themselves might be enabled to buy it at their own price, that no part of it should be exported again but at such an expense as would sufficiently discourage that exportation. Their avidity, however, upon this, as well as upon many other occasions, disappointed itself of its object. This enormous duty presented such a temptation to smuggling that great quantities of this commodity were clandestinely exported, probably to all the manufacturing countries of Europe, put particularly to Holland, not only from Great Britain but from Africa. Upon this account, by the 14th George III, c. 10, this duty upon exportation was reduced to five shillings the hundredweight.
