 the latter. But whatever inconvenience might arise to the maltster from being obliged to advance a heavier tax, it could easily be remedied by granting him a few months longer credit than is at present commonly given to the brewer.

Nothing could reduce the rent and profit of barley land which did not reduce the demand for barley. But a change of system, which reduced the duties upon a quarter of malt brewed into beer and ale from twenty-four and twenty-five shillings to eighteen shillings, would be more likely to increase than diminish that demand. The rent and profit of barley land, besides, must always be nearly equal to those of other equally fertile and equally well cultivated land. If they were less, some part of the barley land would soon be turned to some other purpose; and if they were greater, more land would soon be turned to the raising of barley. When the ordinary price of any particular produce of land is at what may be called a monopoly price, a tax upon it necessarily reduces the rent and profit of the land which grows it. A tax upon the produce of those precious vineyards, of which the wine falls so much short of the effectual demand, that its price is always above the natural proportion to that of the produce of others equally fertile and equally well cultivated land, would necessarily reduce the rent and profit of those vineyards. The price of the wines being already the highest that could be got for the quantity commonly sent to market, it could not be raised higher without diminishing that quantity; and the quantity could not be diminished without still greater loss, because the lands could not be turned to any other equally valuable produce. The whole weight of the tax, therefore, would fall upon the rent and profit; properly upon the rent of
