Mr. Sauerbeck, also an advocate of the gold standard, and whose work has the approval of the Statistical Society, takes as a datum line the prices ruling from 1867 to 1870. Rating those at 100 he finds that by 1873 prices had risen to 111, by 1886 they had fallen to 69, and by September, 1887, to 68.7. He declares the average prices for the first nine months of 1887 to have been the lowest reached for a hundred years.
BOTH GOLD AND SILVER VARIABLE IN VALUE.
The fact that the metals have separated considerably since 1873, and that silver bullion now sells at less than par value of $1.29 per ounce, is taken to signify that silver has fallen—not that gold has risen. This proceeds from the assumption that whenever a change takes place in the relation between gold and any other article the change must necessarily be in the other article. This assumption, in turn, is based on the absurd idea that calling gold a "standard" will insure it against change.
Among political economists it is a well-recognized principle that neither gold or silver is exempt from the universal application of the law of supply and demand. That law governs gold and silver, not only as commodities, but as money, and governs as well all other kinds of money that may be used. And while the advocate of the single gold standard is at all times ready to concede the truth of this assertion as to silver, he is confident that it does not and can not apply to gold; that the economic law which makes supply and demand a regulator of value is suspended as to gold.
That a metallic money, whether of gold or silver, is very far from being stable is admitted by innumerable authorities, of whom I will cite only a few.
Dr. Adam Smith, in his "Wealth of Nations," book 1, chapter 5, says:
Gold and silver, like every other commodity, vary in their value. The discovery of the abundant mines of America reduced in the sixteenth century the value of gold and silver in Europe to about a third of what it had been before. This revolution in their value, though perhaps the greatest, is by no means the only one of which history gives some account.
And again:
Increase the scarcity of gold to a certain degree and the smallest bit of it may be more precious than a diamond.
