The revenue arising from this system of taxation, however, might not immediately increase in proportion to the number of people who were subjected to it. Great indulgence would for some time be due to those provinces of the empire which were thus subjected to burdens to which they had not before been accustomed, and even when the same taxes came to be levied everywhere as exactly as possible, they would not everywhere produce a revenue proportioned to the numbers of the people. In a poor country the consumption of the principal commodities subject to the duties of customs and excise is very small, and in a thinly inhabited country the opportunities of smuggling are very great. The consumption of malt liquors among the inferior ranks of people in Scotland is very small, and the excise upon malt, beer, and ale produces less there than in England in proportion to the numbers of the people and the rate of the duties, which upon malt is different on account of a supposed difference of quality. In these particular branches of the excise there is not, I apprehend, much more smuggling in the one country than in the other. The duties upon the distillery, and the greater part of the duties of customs, in proportion to the numbers of people in the respective countries, produce less in Scotland than in England, not only on account of the smaller consumption of the taxed commodities, but of the much greater facility of smuggling. In Ireland the inferior ranks of people are still poorer than in Scotland, and many parts of the country are almost as thinly inhabited. In Ireland, therefore, the consumption of the taxed commodities might, in proportion to the number of the people, be still less than Scotland, and the facility of smuggling nearly the same. In America and the West Indies the white people even of the lowest rank are in much better circumstances than those of the same rank in England, and their consumption of all the luxuries in which they usually indulge themselves is probably much greater. The blacks, indeed, who make the greater part of the inhabitants both of the southern colonies upon the continent and of the West India islands, as they are in a state of slavery, are, no doubt, in a worse condition than the poorest people either in Scotland or Ireland. We must not, however, upon that account, imagine that they are worse fed, or that their consumption of articles which might be subjected to moderate duties is less than that even of the lower ranks of people in England. In order that they may work well, it is the interest of their master that they should be fed well and kept in good heart in the same manner as it is his interest that his working cattle should be so. The blacks accordingly have almost everywhere their allowance of rum and molasses or spruce beer in the same manner as the white servants, and this allowance would not probably be withdrawn though those articles should be subjected to moderate duties. The consumption of the taxed commodities, therefore, in proportion to the number of inhabitants, would probably be as great in America and the West Indies as in any part of the British empire. The opportunities of smuggling, indeed, would be much greater; America, in proportion to the extent of the country, being much more thinly inhabited than either Scotland or Ireland. If the revenue, however, which is at present raised by the different duties upon malt and malt liquors were to be levied by a single duty upon malt, the opportunity of smuggling in the most important branch of the excise would be almost entirely taken away: and if the duties of customs, instead of being imposed upon almost all the different articles of importation, were confined to a few of the most general use and consumption, and if the levying of those duties were subjected to the excise laws, the opportunity of smuggling, though not so entirely taken away, would be very much diminished. In consequence of those two, apparently, very simple and easy alterations, the duties of customs and excise might probably produce a revenue as great in proportion to the consumption of the most thinly inhabited province as they do at present in proportion to that of the most populous.

The Americans, it has been said, indeed, have no gold or silver money; the interior commerce of the country being carried on by a paper currency, and the gold and silver which occasionally come among them being all sent to Great Britain in return for the commodities which they receive from us. But without gold and silver, it is added, there is no possibility of paying taxes. We already get all the gold and silver which they have. How is it possible to draw from them what they have not?
