From 1595 to 1620, both inclusive, the average price of the quarter of nine bushels of the best wheat, at Windsor market, appears, from the accounts of Eton college, to have been L.2 : 1 : 6-9/13. From which sum, neglecting the fraction, and deducting a ninth, or 4s. 7-1/3d., the price of the quarter of eight bushels comes out to have been L.1 : 16 : 10-2/3. And from this sum, neglecting likewise the fraction, and deducting a ninth, or 4s. 1-1/9d., for the difference between the price of the best wheat and that of the middle wheat, the price of the middle wheat comes out to have been about L.1 : 12 : 8-8/9, or about six ounces and one-third of an ounce of silver. From 1621 to 1636, both inclusive, the average price of the same measure of the best wheat, at the same market, appears, from the same accounts, to have been L.2 : 10s.; from which, making the like deductions as in the foregoing case, the average price of the quarter of eight bushels of middle wheat comes out to have been L.1 : 19 : 6, or about seven ounces and two-thirds of an ounce of silver. _Third Period._--Between 1630 and 1640, or about 1636, the effect of the discovery of the mines of America, is reducing the value of silver, appears to have been completed, and the value of that metal seems never to have sunk lower in proportion to that of corn than it was about that time. It seems to have risen somewhat in the course of the present century, and it had probably begun to do so, even some time before the end of the last. From 1637 to 1700, both inclusive, being the sixty-four last years of the last century, the average price of the quarter of nine bushels of the best wheat, at Windsor market, appears, from the same accounts, to have been L.2 : 11 : 0-1/3, which is only 1s. 0-1/3d. dearer than it had been during the sixteen years before. But, in the course of these sixty-four years, there happened two events, which must have produced a much greater scarcity of corn than what the course of the seasons would otherwise have occasioned, and which, therefore, without supposing any further reduction in the value of silver, will much more than account for this very small enhancement of price.
