In 1804, the English government raised the duties on sugar 20 per cent. It might have been expected, that their average product to the public exchequer would have been advanced in the same ratio; i. e. from 2,778,000l. the former amount, to 3,330,000l.: instead of which the increased duties produced but 2,537,000l.; exhibiting an absolute deficit. Speech of Henry Brougham, Esq., M. P., March 13, 1817.
