150 the result of labour which would otherwise have remained unexerted; or of assistance rendered to labour by improvements or by modes of co-operation to which recourse would not have been had if an inducement had not been offered for raising a larger produce.

§ 3. From these considerations it appears that a country will seldom have a productive agriculture, unless it has a large town population, or the only available substitute, a large export trade in agricultural produce to supply a population elsewhere. I use the phrase town population for shortness, to imply a population non-agricultural; which will generally be collected in towns or large villages, for the sake of combination of labour. The application of this truth by Mr. Wakefield to the theory of colonization, has excited much attention, and is doubtless destined to excite much more. It is one of those great practical discoveries, which, once made, appears so obvious that the merit of making them seems less than it is. Mr. Wakefield was the first to point out that the mode of planting new settlements, then commonly practised—setting down a number of families side by side, each on its piece of land, all employing themselves in exactly the same manner,—though in favourable circumstances it may assure to those families a rude abundance of mere necessaries, can never be other than unfavourable to great production or rapid growth: and his system consists of arrangements for securing that every colony shall have from the first a town population bearing due proportion to its agricultural, and that the cultivators of the soil shall not be so widely scattered as to be deprived by distance, of the benefit of that town population as a market for their produce. The principle on which the scheme is founded, does not depend on any theory respecting the superior productiveness of land held in large portions, and cultivated by hired labour. Supposing it true that land yields the greatest produce when divided into small properties and cultivated by peasant
