The inferiority of the quality, indeed, compared with that of the produce of English dairies, is fully equal to that of the price. But this inferiority of quality is, perhaps, rather the effect of this lowness of price, than the cause of it. Though the quality was much better, the greater part of what is brought to market could not, I apprehend, in the present circumstances of the country, be disposed of at a much better price; and the present price, it is probable, would not pay the expense of the land and labour necessary for producing a much better quality. Through the greater part of England, notwithstanding the superiority of price, the dairy is not reckoned a more profitable employment of land than the raising of corn, or the fattening of cattle, the two great objects of agriculture. Through the greater part of Scotland, therefore, it cannot yet be even so profitable. The lands of no country, it is evident, can ever be completely cultivated and improved, till once the price of every produce, which human industry is obliged to raise upon them, has got so high as to pay for the expense of complete improvement and cultivation. In order to do this, the price of each particular produce must be sufficient, first, to pay the rent of good corn land, as it is that which regulates the rent of the greater part of other cultivated land; and, secondly, to pay the labour and expense of the farmer, as well as they are commonly paid upon good corn land; or, in other words, to replace with the ordinary profits the stock which he employs about it. This rise in the price of each particular produce; must evidently be previous to the improvement and cultivation of the land which is destined for raising it. Gain is the end of all improvement; and nothing could deserve that name, of which loss was to be the necessary consequence. But loss must be the necessary consequence of improving land for the sake of a produce of which the price could never bring back the expense. If the complete improvement and cultivation of the country be, as it most certainly is, the greatest of all public advantages, this rise in the price of all those different sorts of rude produce, instead of being considered as a public calamity, ought to be regarded as the necessary forerunner and attendant of the greatest of all public advantages.
