war, in 1763 (by the 4th Geo. III Chap. 15. Sect. 12.), all the duties, except £3 10 s. were allowed to be drawn back, upon the exportation to the colonies of all wines, except French wines, to the commerce and consumption of which national prejudice would allow no sort of encouragement. The period between the granting of this indulgence and the revolt of our North American colonies was probably too short to admit of any considerable change in the customs of those countries.
The same act, which, in the drawback upon all wines, except French wines, thus favoured the colonies so much more than other countries; in those, upon the greater part of other commodities, favoured them much less. Upon the exportation of the greater part of commodities to other countries, half the old subsidy was drawn back. But this law enacted, that no part of that duty should be drawn back upon the exportation to the colonies of any commodities, of the growth or manufacture either of Europe or the East Indies, except wines, white calicoes and muslins.
Drawbacks were, perhaps, originally granted for the encouragement of the carrying trade, which, as the freight of the ships is frequently paid by foreigners in money, was supposed to be peculiarly fitted for bringing gold and silver into the country. But though the carrying trade certainly deserves no peculiar encouragement, though the motive of the institution was, perhaps, abundantly foolish, the institution itself seems reasonable enough. Such drawbacks cannot force into this trade a greater share of the capital of the country than what would have gone to it of its own accord, had there been no duties upon importation. They only prevent its being excluded altogether by those duties. The carrying trade, though it deserves no preference, ought not to be precluded, but to be left free like all other trades. It is a necessary resource for those capitals which cannot find employment either in the agriculture or in the manufactures of the country, either in its home trade or in its foreign trade of consumption.
