Upon the earnest and repeated remonstrances of our ministers at London in opposition to this discrimination against American and in favor of African rice, as a violation of the subsisting convention, Parliament, by the act of 9th July, 1842, again equalized the duty on all foreign rough rice by fixing it at 7s. per quarter., In the intervening period, however, of nearly six years large importations had been made into Great Britain of American rough rice, which was subjected to a duty of 2s. 6d. per bushel; but the importers, knowing their rights under the convention, claimed that it should be admitted at the rate of 1 penny per quarter, the duty imposed on African rice. This claim was resisted by the British Government, and the excess of duty was paid, at the first under protest, and afterwards, in consequence of an arrangement with the board of customs, by the deposit of exchequer bills. It seems to have been a clear violation both of the letter and spirit of the convention to admit rough rice "the growth" of Africa at 1 penny per quarter, whilst the very same article "the growth" of the United States was charged with a duty of 2s. 6d. per bushel. The claim of Great Britain, under the same article of the convention, is founded on the tariff act of 30th August, 1842. Its twenty-fifth section provides "that nothing in this act contained shall apply to goods shipped in a vessel bound to any port of the United States, actually having left her last port of lading eastward of the Cape of Good Hope or beyond Cape Horn prior to the 1st day of September, 1842; and all legal provisions and regulations existing immediately before the 30th day of June, 1842, shall be applied to importations which may be made in vessels which have left such last port of lading eastward of the Cape of Good Hope or beyond Cape Horn prior to said 1st day of September, 1842." The British Government contends that it was a violation of the second article of the convention for this act to require that "articles the growth, produce, or manufacture" of Great Britain, when imported into the United States in vessels which had left their last port of lading in Great Britain prior to the 1st day of September, 1842, should pay any "higher or other duties" than were imposed on "like articles" "the growth, produce, or manufacture" of countries beyond the Cape of Good Hope and Cape Horn. Upon a careful consideration of the subject I arrived at the conclusion that this claim on the part of the British Government was well founded. I deem it unnecessary to state my reasons at length for adopting this opinion, the whole subject being fully explained in the letter of the Secretary of the Treasury and the accompanying papers.
