It is a kind of a bill of exchange, or order payable at the will of the bearer. Adam Smith says: A guinea may be considered as a bill for a certain quantity of necessaries and conveniences upon all the tradesmen in the neighborhood. Jevons's "Money and Exchanges," chapter 8, says: Those who use coins in ordinary business need never inquire how much metal they contain. Probably not one person in two thousand in this kingdom knows, or need know, that a sovereign should contain 123.27447 grains of standard gold. Money is made to go. People want coin, not to keep in their own pockets, but to pass it off into their neighbors' pockets. Henry Thornton, in his work on Paper Credit, says: Money of every kind is an order for goods. It is so considered by the laborer, when he receives it, and it is almost instantly turned into money's worth. It is merely in instrument by which the purchasable stock of the country is distributed with convenience and advantage among the several members of the community. John Stuart Mill says: The pounds or shillings which a person receives are a sort of ticket or order which he can present for payment at any shop he pleases, and which entitle him to receive a certain value of any commodity that he makes choice. McLeod, Elements of Banking, Chapter I, says: When persons take a piece of money in exchange for services, or products, they can neither eat it, nor drink it, nor clothe themselves with it. The only reason why they take it is, because they believe they can exchange it away whenever they please for other things which they require. On that view of money McLeod feels justified in styling it credit, and he quotes in support of such a use of the term credit, Burke's description of gold and silver as "the two great recognized species that represent the lasting conventional credit of mankind." Prof. Francis A. Walker, Money, Trade, etc., page 25, speaking of carved pebbles, glass beads, shells and red feathers, used as money in certain countries at certain times, says: They were good money, though serving no purpose but ornament and decoration. They were desired by the community in general; men would give for them the fruits of their labor, knowing that with them they could obtain most conveniently in time, in form, and in amount, the fruits of the labor of others. On page 30 he says: Men take money with the expectation of parting with it; this is the use to which they mean to put it. Again, Mr. Walker says:
