It is farther established by experience, that a brisk or slack demand for commodities and labour, and particularly for corn, has a considerable effect on the value of gold. Such a demand not only occasions a more rapid circulation of money, and enables the same quantity to perform a greater number of transactions, but calls into action a greater quantity of credit and private paper,[R] so that a general rise of bullion prices, including labour, seems to be at all times possible, even without any fresh importations of the precious metals; and the only practical limit to this rise, is the turn of the exchange, and the impossibility of maintaining the exchanges nearly at par beyond a certain elevation of labour and commodities. The secondary and incidental causes here enumerated, as affecting the value of gold, often completely overcome the effects arising from the primary cause. The state of bullion prices in most of the countries of the commercial world make it evident, that the efficiency of labour, and the abundance of exportable commodities, are much more powerful in lowering the value of bullion in the countries where they prevail, than high profits in raising it; and the same appears to be true, in reference to an increased demand for corn and labour. It cannot be doubted that the rate of interest and profits was comparatively high during the late war, and this high rate of profits would naturally have a tendency to lower the bullion price of labour; but this was more than counterbalanced by the tendency of a brisk demand for corn and labour to raise money prices generally, including labour, and the consequence was a fall, during the greatest part of the time, in the value of bullion. It can as little be doubted, that the rate of interest and profits has fallen since the war, and this low rate of profits would have a natural tendency to raise the bullion price of labour; but this has been more than counterbalanced by the tendency of a slack demand for corn and labour to lower prices generally, and the consequence has been a rise in the value of gold, and a still greater rise in the value of the currency. This rise, however, in the value of the currency, has been by no means so considerable as those are inclined to make it, who would measure it by the fall of agricultural produce; nor is it so inconsiderable as those imagine who would measure it solely by the difference between paper and gold. But whether this difference is the whole of what can be fairly attributed to the Bank Restriction and the return to cash payments, or not, it may by no means be the whole change which has taken place in the value of the currency, when compared with an object which has not changed.
