Want of Means of Subdivision.

A third but it may be a minor inconvenience of barter arises from the impossibility of dividing many kinds of goods. A store of corn, a bag of gold dust, a carcase of meat, may be portioned out, and more or less may be given in exchange for what is wanted. But the tailor, as we are reminded in several treatises on political economy, may have a coat ready to exchange, but it much exceeds in value the bread which he wishes to get from the baker, or the meat from the butcher. He cannot cut the coat up without destroying the value of his handiwork. It is obvious that he needs some medium of exchange, into which he can temporarily convert the coat, so that he may give a part of its value for bread, and other parts for meat, fuel, and daily necessaries, retaining perhaps a portion for future use. Further illustration is needless; for it is obvious that we need a means of dividing and distributing value according to our varying requirements.

In the present day barter still goes on in some cases, even in the most advanced commercial countries, but only when its inconveniences are not experienced. Domestic servants receive part of their wages in board and lodging: the farm labourer may partially receive payment in cider, or barley, or the use of a piece of land. It has always been usual for the miller to be paid by a portion of the corn which he grinds. The truck or barter system, by which workmen took their wages in kind, has hardly yet been extinguished in some parts of England. Pieces of land are occasionally exchanged by adjoining landowners; but all these are comparatively trilling cases. In almost all acts of exchange money now intervenes in one way or other, and even when it does not pass from hand to hand, it serves as the measure by which the amounts given and received are estimated. Commerce begins with barter, and in a certain sense it returns to barter; but the last form of barter, as we shall see, is very different from the first form. By far the greater part of commercial payments are made at the present day in England apparently without the aid of metallic money; but they are readily adjusted, because money acts as the common denominator, and what is bought in one direction is balanced off against what is sold in another direction.

Chapter II

Exchange

Money is the measure and standard of value and the medium of exchange, yet it is not necessary that I should enter upon more than a very brief discussion concerning the nature of value, and the advantage of exchange. Every one must allow that the exchange of commodities depends upon the obvious principle that each of our wants taken separately requires a limited quantity of some article to produce satisfaction. Hence as each want becomes fully satiated, our desire, as Senior so well remarked, is for variety, that is, for the satisfaction of some other want. The man who is supplied daily with three pounds of bread, will not desire more bread; but he will have a strong inclination for beef, and tea, and alcohol. If he happen to meet with a person who has plenty of beef but no bread, each will give that which is less desired for that which is more desired. Exchange has been called the barter of the superfluous for the necessary, and this definition will be correct if we state it as the barter of the comparatively superfluous for the comparatively necessary.

It is impossible, indeed, to decide exactly how much bread, or beef, or tea, or how many coats and hats a person needs. There is no precise limit to our desires, and we can only say, that as we have a larger supply of a substance, the urgency of our need for more is in some proportion weakened. A cup of water in the desert, or upon the field of battle, may save life, and become infinitely useful. Two or three pints per day for each person are needful for drinking and cooking purposes. A gallon or two per day are highly requisite for cleanliness; but we soon reach a point at which further supplies of water are of very minor importance. A modern town population is found to be satisfied with about twenty-five gallons per head per day for all purposes, and a further supply would possess little utility. Water, indeed, may be the reverse of useful, as in the case of a flood, or a damp house, or a wet mine.
