Now, it is perfectly clear that neither a bank note, nor a check creates any new right; it merely records on paper a right to have money which already exists, and it is used for the purpose of transferring that right to have money to someone else. It will be noted now, and I want you to keep this observation clearly in mind, that all banks are banks of issue, that is issues of credit. MacLeod says that the very meaning of the words "To Bank" is to issue a right of action or a credit, in exchange for money or other debts; and when once the banker has issued this right of action, or right to have money, to his customer by writing it down to his credit, it makes not the slightest difference as to his liability whether he delivers his own promissory note, that is a bank note, to his customer, or whether he merely creates the credit, and gives him the right to transfer it to someone else by means of a check. When a person deposits money at the bank, it is not his intention to deprive himself of the use of it; on the contrary, he means to have as free use of it as if it were in his own purse. The depositor, therefore, lends his money to his banker, but yet at the same time has the free use of it, as the bank employs that same money in promoting trade; upon the strength of the money being deposited with the bank, it buys debts with its promises to pay, either in the form of "Bank Notes," or of credit on its books, several times exceeding the amount of the cash placed with it; and the depositors who sell the bank their debts, have the free use of the very same coin which the depositor has the right to demand; thus the lender that is, the depositor, and the borrower that is, the banker, have the same right at the same time to the free use of the same money. All banking depends on the calculation that only a certain small portion of each set of depositors will demand the actual cash, but that the majority will be satisfied with the mere promise, the "Bank Notes" or the credit on the books of the bank.
