_Fourth_: When a draft has been accepted, it becomes the promissory note of the one accepting it, as he promises to pay it on the day named in the draft. An accepted draft is only another form of a promissory note, for if A owes B $1,000, and B draws upon A for that amount, and A accepts the draft, A is in precisely the same position as he would have been if he had sent B his promissory note for $1,000. In the banking world a draft, after it has been accepted, is often called and known as an "Acceptance." _Fifth_: A Bill of Exchange in its ordinary or usual sense, is an order of one person upon another to pay a third person a sum of money. MR. MANUFACTURER: That is precisely what you said a draft was. MR. BANKER: Just wait a moment, please, until I finish, and you will note the difference. The Bill of Exchange is the medium of settling accounts or debts between parties residing at a distance from each other, without the intervention of money by exchanging checks or drafts. MR. MANUFACTURER: Then they are identically the same thing except a bill of exchange acquires its name from the fact that it settles debts at a distance. MR. BANKER: That is the exact distinction, if one is to be made at all, and I think it will be well for us to make this distinction to save confusion in our conversation, although in the ordinary and usual language of the street, or the business world, the terms, or words, "draft," "acceptance" and "Bill of Exchange" are used indiscriminately the one for the other. If the definition of Mr. Lawyer stands, and I think it is a very good one, when he said "the science of exchange is to make one debt pay another debt," the science of Bills of Exchange is to make one debt pay another debt at a distant point. This is not a distinction fully without a difference, because it helps us to classify the transactions and distinguish them in a way as we go along. A simple illustration is this: A, who lives in Boston, owes B, who lives in San Francisco, $1,000, and C, who lives in San Francisco, owes D, who lives in Boston, $1,000. B and D could exchange drafts with each other; then B and D could collect each other's drafts. But B could sell his draft on A to C for $1,000 and C could pay his debt of $1,000 to D by forwarding him the draft on A. D would then collect the draft on A. It will be seen at once that this transaction has saved the expense of sending $1,000 in money from Boston to San Francisco, and also of sending $1,000 in money from San Francisco to Boston at great expense by express. This transaction between Boston and San Francisco is known and called a transaction in Domestic Exchange.
