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.
