economy; which, in time of peace, has generally conducted itself with the slothful and negligent profusion that is, perhaps, natural to monarchies; and, in time of war, has constantly acted with all the thoughtless extravagance that democracies are apt to fall into, could be safely trusted with the management of such a project, must at least be a good deal more doubtful.
The post-office is properly a mercantile project. The government advances the expense of establishing the different offices, and of buying or hiring the necessary horses or carriages, and is repaid, with a large profit, by the duties upon what is carried. It is, perhaps, the only mercantile project which has been successfully managed by, I believe, every sort of government. The capital to be advanced is not very considerable. There is no mystery in the business. The returns are not only certain but immediate.
Princes, however, have frequently engaged in many other mercantile projects, and have been willing, like private persons, to mend their fortunes, by becoming adventurers in the common branches of trade. They have scarce ever succeeded. The profusion with which the affairs of princes are always managed, renders it almost impossible that they should. The agents of a prince regard the wealth of their master as inexhaustible; are careless at what price they buy, are careless at what price they sell, are careless at what expense they transport his goods from one place to another. Those agents frequently live with the profusion of princes; and sometimes, too, in spite of that profusion, and by a proper method of making up their accounts, acquire the fortunes of princes. It was thus, as we are told by Machiavel, that the agents of Lorenzo of Medicis, not a prince of mean abilities, carried on his trade. The republic of Florence was several times obliged to pay the debt into which their extravagance had involved him. He found it convenient, accordingly to give up the business of merchant, the business to which his family had originally owed their fortune, and, in the latter part of his life, to employ
