If, on the contrary, the sum of the repayments from certain other customers falls commonly very much short of the advances which it makes to them, it cannot with any safety continue to deal with such customers, at least if they continue to deal with it in this manner. The stream which is in this case continually running out from its coffers is necessarily much larger than that which is continually running in; so, that unless they are replenished by some great and continual effort of expense, those coffers must soon be exhausted altogether.
The banking companies of Scotland, accordingly, were for a long time very careful to require frequent and regular repayments from all their customers, and did not care to deal with any person, whatever might be his fortune or credit, who did not make, what they called, frequent and regular operations with them. By this attention, besides saving almost entirely the extraordinary expense of replenishing their coffers, they gained two other very considerable advantages.
First, by this attention they were enabled to make some tolerable judgment concerning the thriving or declining circumstances of their debtors, without being obliged to look out for any other evidence besides what their own books afforded them; men being for the most part either regular or irregular in their repayments, according as their circumstances are either thriving or declining. A private man who lends out his money to perhaps half a dozen or a dozen of debtors, may, either by himself or his agents,
