Among the witnesses before the committee were John Stuart Mill, Lord Overstone, and many other men distinguished in the world of letters and finance. I am informed by the Librarian of Congress that there is but one copy of the work in the United States. It would be well worth while for Congress to order a number of copies of it printed, for there is no work with which I am acquainted that contains so much practical information as to the working of the single gold standard. According to the testimony taken before that committee, the experience of Great Britain since 1819 shows that gold alone, even when re-enforced by paper money convertible exclusively into gold, instead of being a beneficent instrument of valuation, has proved a cruel instrument of injustice. A brief consideration of the causes which affect the movement of gold will not be out of place in this connection. RATIONALE OF THE MOVEMENT OF GOLD. Why is it that gold leaves country and goes to another? For one reason only--the advantage of its owner. Whenever he can make a profit by sending it out, the gold goes; and the period when that profit can be made is indicated when the prices of goods that are internationally dealt in are either rising in the country which it leaves or falling in the country to which it goes. It is only to pay for importable goods that gold ever leaves the country in which the owner resides. Being an international money, and receivable everywhere at its full face value, gold loses nothing by transfer; hence it is sent wherever it will for the time being have the greatest purchasing power. Whenever the general range of prices in this country of commodities internationally dealt in becomes than higher than the general range of the same commodities abroad, it is manifest that then gold can used to advantage by purchasing those articles abroad and selling them here. If the gold that goes out goes from stock that has been hoarded here, the outflow has no immediate or direct effect upon prices in this country, although, by increasing or "inflating" the volume of money abroad it assists in raising prices there, and thus tends to secure for our exported products a better price in the foreign market. But if the gold goes from the amount that is in active circulation here, and if the void created by this outflow is not filled with other forms of money, such as silver, or paper, it results in a reduction of the volume of money in actual use in this country, while at the same time increasing the volume of money abroad. This increase in the foreign money stock causes a rise of prices abroad, while the corresponding reduction of our currency causes a proportionate fall of prices here, hence there is a constant tendency to an equilibrium of prices of all articles of international commerce.
