, notwithstanding this prohibition, should in another be owing to the extraordinary encouragement given to exportation.

It would be more proper, perhaps, to consider this variation in the average money price of corn as the effect rather of some gradual rise in the real value of silver in the European market, than of any fall in the real average value of corn. Corn, it has already been observed, is at distant periods of time a more accurate measure of value than either silver, or perhaps any other commodity. When, after the discovery of the abundant mines of America, corn rose to three and four times its former money price, this change was universally ascribed, not to any rise in the real value of corn, but to a fall in the real value of silver. If during the first sixty-four years of the present century, therefore, the average money price of corn has fallen somewhat below what it had been during the greater part of the last century, we should in the same manner impute this change, not to any fall in the real value of corn, but to some rise in the real value of silver in the European market.

The high price of corn during these ten or twelve years past, indeed, has occasioned a suspicion that the real value of silver still continues to fall in the European market. This high price of corn, however, seems evidently to have been the effect of the extraordinary unfavorableness of the seasons, and ought therefore to be regarded, not as a permanent, but as a transitory and occasional event. The seasons for these ten or twelve years past have been unfavorable through the greater part of Europe; and the disorders of Poland have very much increased the scarcity in all those countries, which, in dear years, used to be supplied from that market. So long a course of bad seasons, though not
