An augmentation, or a direct raising of the coin, always is, and from its nature must be, an open and avowed operation. By means of it pieces of a smaller weight and bulk are called by the same name which had before been given to pieces of a greater weight and bulk. The adulteration of the standard, on the contrary, has generally been a concealed operation. By means of it pieces were issued from the mint of the same denominations, and, as nearly as could be contrived, of the same weight, bulk, and appearance with pieces which had been current before of much greater value. When King John of France, in order to pay his debts, adulterated his coin, all the officers of his mint were sworn to secrecy. Both operations are unjust. But a simple augmentation is an injustice of open violence, whereas the adulteration is an injustice of treacherous fraud. This latter operation, therefore, as soon as it has been discovered, and it could never be concealed very long, has always excited much greater indignation than the former. The coin after any considerable augmentation has very seldom been brought back to its former weight; but after the greater adulterations it has almost always been brought back to its former fineness. It has scarce ever happened that the fury and indignation of the people could otherwise be appeased.

In the end of the reign of Henry VIII and in the beginning of that of Edward VI the English coin was not only raised in its denomination, but adulterated in its standard. The like frauds were practised in Scotland during the minority of James VI. They have occasionally been practised in most other countries.

That the public revenue of Great Britain can never be completely liberated, or even that any considerable progress can ever be made towards that liberation, while the surplus of that revenue, or what is over and above defraying the annual expense of the peace establishment, is so very small, it seems altogether in vain to expect. That liberation, it is evident, can never be brought about without either some very considerable augmentation of the public revenue, or some equally considerable reduction of the public expense.

A more equal land-tax, a more equal tax upon the rent of houses, and such alterations in the present system of customs and excise as those which have been mentioned in the foregoing chapter might, perhaps, without increasing the burden of the greater part of the people, but only distributing the weight of it more equally upon the whole, produce a considerable augmentation of revenue. The most sanguine projector, however, could scarce flatter himself that any augmentation of this kind would be such as could give any reasonable hopes either of liberating the public revenue altogether, or even of making such progress towards that liberation in time of peace as either to prevent or to compensate the further accumulation of the public debt in the next war.

By extending the British system of taxation to all the different provinces of the empire inhabited by people of either British or European extraction, a much greater augmentation of revenue might be expected. This, however, could scarce, perhaps, be done, consistently with the principles of the British constitution, without admitting into the British Parliament, or if you will into the states general of the British empire, a fair and equal representation of all those different provinces, that of each province bearing the same proportion to the produce of its taxes as the representation of Great Britain might bear to the produce of the taxes levied upon Great Britain. The private interest of many powerful individuals, the confirmed prejudices of great bodies of people seem, indeed, at present, to oppose to so great a change such obstacles as it may be very difficult, perhaps altogether impossible, to surmount. Without, however, pretending to determine whether such a union be practicable or impracticable, it may not, perhaps, be improper, in a speculative work of this kind, to consider how far the British system of taxation might be applicable to all the different provinces of the empire, what revenue might be expected from it if so applied, and in what manner a general union of this kind might be likely to affect the happiness and prosperity of the different provinces comprehended within it. Such a speculation can at worst be regarded but as a new Utopia, less amusing certainly, but not more useless and chimerical than the old one.
