But as capital can be increased only by savings from revenue, the monopoly, by hindering it from affording so great a revenue as it would otherwise afford, necessarily hinders it from increasing so fast as it would otherwise increase, and consequently from maintaining a still greater quantity of productive labour, and affording a still greater revenue to the industrious inhabitants of that country.

By raising the rate of mercantile profit, the monopoly discourages the improvement of land. The profit of improvement depends upon the difference between what the land actually produces, and what, by the application of a certain capital, it can be made to produce. If this difference affords a greater profit than what can be drawn from an
