 five-and-twenty per cent cheaper than it had been during the last sixty-four years of the last century; and about nine shillings and sixpence cheaper than it had been during the sixteen years preceding 1636, when the discovery of the abundant mines of America may be supposed to have produced its full effect; and about one shilling cheaper than it had been in the twenty-six years preceding 1620, before that discovery can well be supposed to have produced its full effect. According to this account, the average price of middle wheat, during these first sixty-four years of the present century, comes out to have been about thirty-two shillings the quarter of eight bushels.

The value of silver, therefore, seems to have risen somewhat in proportion to that of corn during the course of the present century, and it had probably begun to do so even some time before the end of the last.

In 1687, the price of the quarter of nine bushels of the best wheat at Windsor market was £1 5s. 2d., the lowest price at which it had ever been from 1595.

In 1688, Mr. Gregory King, a man famous for his knowledge in matters of this kind, estimated the average price of wheat in years of moderate plenty to be to the grower 3s. 6d. the bushel, or eight-and-twenty shillings the quarter. The grower's price I understand to be the same with what is sometimes called the contract price, or the price at which a farmer contracts for a certain number of years to deliver a certain quantity of corn to a dealer. As a contract of this kind saves the farmer the expense and trouble of marketing, the contract price is generally lower than what is supposed to be the average market price. Mr. King had judged eight-and-twenty shillings the quarter to be at that time the ordinary contract price in years of moderate plenty.
