observe and inquire both constantly and carefully into the conduct and situation of each of them. But a banking company, which lends money to perhaps five hundred different people, and of which the attention is continually occupied by objects of a very different kind, can have no regular information concerning the conduct and circumstances of the greater part of its debtors beyond what its own books afford it. In requiring frequent and regular repayments from all their 'customers, the banking companies of Scotland had probably this advantage in view.
Secondly, by this attention they secured themselves from the possibility of issuing more paper money than what the circulation of the country could easily absorb and employ. When they observed, that within moderate periods of time the repayments of a particular customer were upon most occasions fully equal to the advances which they had made to him, they might be assured that the paper money which they had advanced to him, had not at any time exceeded the quantity of gold and silver which he would otherwise have been obliged to keep by him for answering occasional demands; and that, consequently, the paper money, which they had circulated by his means, had not at any time exceeded the quantity of gold and silver which would have circulated in the country, had there been no paper money.
