We will further suppose, that, from the increase of population, more corn is wanted than can be raised; and, consequently, importations are made at an increased price, — equal, say, to fifty per cent. Now if, for the sake of convenience, we take the price of corn to have been originally one dollar a bushel, and to have advanced to one dollar and fifty cents, it will come to pass that tier or quality No.1. will have a rent of $45; No. 2, of $30; No. 3, of $20; and No. 4, which now for the first time produces rent, of $5.

This represents the condition of Great Britain, which, besides raising all the wheat her highly cultivated fields can profitably produce, imports some eighty millions of bushels annually. This causes a large increase of prices; consequently, of money rent.
