success of an expedient of this kind must have depended upon three different circumstances; first, upon the demand for some other instrument of commerce, besides gold and silver money; or upon the demand for such a quantity of consumable stock, as could not be had without sending abroad the greater part of their gold and silver money, in order to purchase it; secondly, upon the good credit of the government which made use of this expedient; and, thirdly, upon the moderation with which it was used, the whole value of the paper bills of credit never exceeding that of the gold and silver money which would have been necessary for carrying on their circulation, had there been no paper bills of credit. The same expedient was upon different occasions adopted by several other American colonies: but, from want of this moderation, it produced, in the greater part of them, much more disorder than conveniency.
The unstable and perishable nature of stock and credit, however, render them unfit to be trusted to, as the principal funds of that sure, steady and permanent revenue, which can alone give security and dignity to government. The government of no great nation, that was advanced beyond the shepherd state, seems ever to have derived the greater part of its public revenue from such sources.
Land is a fund of a more stable and permanent nature; and the rent of public lands, accordingly, has been the principal source of the public revenue of many a great nation that was much advanced beyond the shepherd state. From the produce or rent of the public lands, the ancient republics of Greece and Italy derived, for a long time, the greater part of that revenue which defrayed the necessary expenses of the commonwealth. The rent of the crown lands constituted for a long time the greater part of the revenue of the ancient sovereigns of Europe.
War and the preparation for war, are the two circumstances which in modern times occasion the greater part of the necessary expense of all
