Prof. F. A. Walker, referring to these schemes, and to similar ones proposed by Count Soden and by Professor Roscher in Germany, criticises them as too cumbersome for general use, but thinks they might be advantageously employed for long-time contracts. The criticism is evidently just; not only are the plans too cumbersome, but they only partially accomplish what is needed. They contain, however, the germ of a plan which it is believed would be both more effective and less open to the criticism mentioned. Long and short time contracts, and cash transactions, are too intimately connected to make it possible in practice to use different and varying standards for each. Since the values of all commodities constitute the only true standard of value, as close an approximation to this standard as possible should be adopted as our standard of value. Since the value of the circulating medium--the money--depends on supply and demand, the supply should be so controlled that the value of the money would always correspond with that of the standard adopted, and since paper money is the cheapest, the most convenient, and the only money entirely free from outside influences affecting its volume and value, our currency should be a paper money. The following is given as the outline of a plan embodying these features and requirements. _The Standard of Value._ Let a commission be appointed by Congress to select a sufficient number of commodities, say, one hundred, to be used as a standard of value. This selection should comprise the commodities most largely bought and sold and most independent of each other in their values; preference should be given to those which are products of this country,--but foreign products should also be included,--and to those which are reliable in quality and of which the prices are regularly quoted--such, for instance, as wheat, corn, oats, rye, barley, cotton, wool, tobacco, rice, gold, silver, lead, copper, tin, iron, steel, cotton and woollen cloths, leather, hides, lumber of various kinds, sugar, beef, pork, mutton, etc. The aim should be, while not including all commodities, which would of course be impossible, to include a sufficient number and of such varied kinds as to fairly represent all. Less than a hundred might be sufficient, or it might be better to take more than that number. With the aid of statisticians, the average price of each of the commodities selected, in their principal markets for a few years past, should be ascertained and tabulated. The commodities, of course, should be of specified grade and quality, and in a specified market, but not necessarily the same market for all.
