The Wealth of Nations_ Books 4-5 - Adam Smith [205]
In China, and in several other governments of Asia, the executive power charges itself both with the reparation of the high roads and with the maintenance of the navigable canals. In the instructions which are given to the governor of each province, those objects, it is said, are constantly recommended to him, and the judgment which the court forms of his conduct is very much regulated by the attention which he appears to have paid to this part of his instructions. This branch of public police accordingly is said to be very much attended to in all those countries, but particularly in China, where the high roads, and still more the navigable canals, it is pretended, exceed very much everything of the same kind which is known in Europe. The accounts of those works, however, which have been transmitted to Europe, have generally been drawn up by weak and wondering travellers; frequently by stupid and lying missionaries. If they had been examined by more intelligent eyes, and if the accounts of them had been reported by more faithful witnesses, they would not, perhaps, appear to be so wonderful. The account which Bernier gives of some works of this kind in Indostan falls very much short of what had been reported of them by other travellers, more disposed to the marvellous than he was. It may too, perhaps, be in those countries, as it is in France, where the great roads, the great communications which are likely to be the subjects of conversation at the court and in the capital, are attended to, and all the rest neglected. In China, besides, in Indostan, and in several other governments of Asia, the revenue of the sovereign arises almost altogether from a land tax or land rent, which rises or falls with the rise and fall of the annual produce of the land. The great interest of the sovereign, therefore, his revenue, is in such countries necessarily and immediately connected with the cultivation of the land, with the greatness of its produce, and with the value of its produce. But in order to render that produce both as great and as valuable as possible, it is necessary to procure to it as extensive a market as possible, and consequently to establish the freest, the easiest, and the least expensive communication between all the different parts of the country; which can be done only by means of the best roads and the best navigable canals. But the revenue of the sovereign does not, in any part of Europe, arise chiefly from a land tax or land rent. In all the great kingdoms of Europe, perhaps, the greater part of it may ultimately depend upon the produce of the land: but that dependency is neither so immediate, nor so evident. In Europe, therefore, the sovereign does not feel himself so directly called upon to promote the increase, both in quantity and value, of the produce of the land, or, by maintaining good roads and canals, to provide the most extensive market for that produce. Though it should be true, therefore, what I apprehend is not a little doubtful, that in some parts of Asia this department of the public police is very properly managed by the executive power, there is not the least probability that, during the present state of things, it could be tolerably managed by that power in any part of Europe.
Even those public works which are of such a nature that they cannot afford any revenue for maintaining themselves, but of which the conveniency is nearly confined to some particular place or district, are always better maintained by a local or provincial revenue, under the management of a local and provincial administration, than by the general revenue of the state, of which
