equal capital in any mercantile employment, the improvement of land will draw capital from all mercantile employments. If the profit is less, mercantile employments will draw capital from the improvement of land. Whatever therefore raises the rate of mercantile profit, either lessens the superiority or increases the inferiority of the profit of improvement; and in the one case hinders capital from going to improvement, and in the other draws capital from it. But by discouraging 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.
