bank, could not have been equal to the stream which, by means of the same dealings, was continually running out. The advances of the bank paper, by exceeding the quantity of gold and silver which, had there been no such advances, he would have been obliged to keep by him for answering occasional demands, might soon come to exceed the whole quantity of gold and silver which (the commerce being supposed the same) would have circulated in the country had there been no paper money; and consequently to exceed the quantity which the circulation of the country could easily absorb and employ; and the excess of this paper money would immediately have returned upon the bank in order to be exchanged for gold and silver. This second advantage, though equally real, was not perhaps so well understood by all the different banking companies of Scotland as the first.
When, partly by the conveniency of discounting bills, and partly by that of cash accounts, the creditable traders of any country can be dispensed from the necessity of keeping any part of their stock by them unemployed and in ready money for answering occasional demands, they can reasonably expect no farther assistance from banks and bankers, who, when they have gone thus far, cannot, consistently with their own interest and safety, go farther. A bank cannot, consistently with its own interest, advance to a trader the whole or even the greater part of the circulating capital with which he trades; because, though that capital is continually returning to him in the shape of money, and going from him in the same shape, yet the whole of the returns is too distant from the whole of the outgoings, and the sum of his repayments could not equal the sum of its advances within such moderate periods of time as suit the conveniency of a bank. Still less could a bank afford to advance him any considerable part of his fixed capital; of the capital which the undertaker of an iron forge, for example, employs in erecting his forge and smelting-house, his workhouses and warehouses, the dwelling-houses of his workmen, etc. ; of the capital which the undertaker of a mine employs in sinking his shafts, in erecting engines for drawing out the water, in
