Again, a most important function of early banks is one which the present banks retain, though it is subsidiary to their main use; viz. the function of remitting money. A man brings money to the bank to meet a payment which he desires to make at a great distance, and the bank, having a connection with other banks, sends it where it is wanted. As soon as bills of exchange are given upon a large scale, this remittance is a very pressing requirement. Such bills must be made payable at a place convenient to the seller of the goods in payment of which they are given, perhaps at the great town where his warehouse is. But this may be very far from the retail shop of the buyer who bought those goods to sell them again in the country. For these, and a multitude of purposes, the instant and regular remittance of money is an early necessity of growing trade; and that remittance it was a first object of early banks to accomplish. These are all uses other than those of deposit banking which banks supplied that afterwards became in our English sense deposit banks. By supplying these uses, they gained the credit that afterwards enabled them to gain a living as deposit banks. Being trusted for one purpose, they came to be trusted for a purpose quite different, ultimately far more important, though at first less keenly pressing. But these wants only affect a few persons, and therefore bring the bank under the notice of a few only. The real introductory function which deposit banks at first perform is much more popular, and it is only when they can perform this more popular kind of business that deposit banking ever spreads quickly and extensively. This function is the supply of the paper circulation to the country, and it will be observed that I am not about to overstep my limits and discuss this as a question of currency. In what form the best paper currency can be supplied to a country is a question of economical theory with which I do not meddle here. I am only narrating unquestionable history, not dealing with an argument where every step is disputed. And part of this certain history is that the best way to diffuse banking in a community is to allow the banker to issue bank-notes of small amount that can supersede the metal currency. This amounts to a subsidy to each banker to enable him to keep open a bank till depositors choose to come to it. The country where deposit banking is most diffused is Scotland, and there the original profits were entirely derived from the circulation. The note issue is now a most trifling part of the liabilities of the Scotch banks, but it was once their mainstay and source of profit. A curious book, lately published, has enabled us to follow the course of this in detail. The Bank of Dundee, now amalgamated with the Royal Bank of Scotland, was founded in 1763, and had become before its amalgamation, eight or nine years since, a bank of considerable deposits. But for
