improvement, the monopoly necessarily retards the natural increase of another great original source of revenue, the rent of land. By raising the rate of profit, too, the monopoly necessarily keeps up the market rate of interest higher than it otherwise would be. But the price of land in proportion to the rent which it affords, the number of years purchase which is commonly paid for it, necessarily falls as the rate of interest rises, and rises as the rate of interest falls. The monopoly, therefore, hurts the interest of the landlord two different ways, by retarding the natural increase, first, of his rent, and secondly, of the price which he would get for his land in proportion to the rent which it affords.

The monopoly indeed raises the rate of mercantile profit, and thereby augments somewhat the gain of our merchants.
