When we speak of the circulation of trade, we understand the circulation of money paid on the account of trade.

The great occupation of the London merchants engages them to simplify their business as much as possible. For this, they commit to brokers every operation which requires no peculiar talents or ingenuity in the merchant himself; and, for a like reason, they commit to the bank and private bankers the care of their cash.

A Scots merchant begins by drawing money from the bank, for which he pays interest: a London merchant begins by putting money into the bank, for which he draws no interest at all.

A London merchant, therefore, can give no order upon the bank, unless at a time when he has money lodged in it.

If he has occasion for money at any time, he sends to the bank the bills he has, before they become due, and the bank discounts them at certain rates, according to their nature.

If it be a foreign bill, the bank in discounting it, retains of the sum, at the rate of 4 per cent. per annum, for the time the bill has to run; but if the bill be at a longer day than 60 days, they will not discount it. So in this case, the merchant must keep his bill until it is within 60 days of the term of payment.

The reason for this is evident: the security upon which such bills stand, is purely mercantile. The nearer, therefore, the payment is, the less risk the bank incurs from the failure of those who are bound in it.

The intention of this operation of discounting bills, is plainly to employ the cash in the bank in a way to draw an interest for it; but as merchants allow their money to lie dead for as short a time as they possibly can, the bank must have quick returns for what they advance upon discount, in order to be constantly ready to answer all demands. This is no loss to the bank, and a prodigious advantage to trade, as I shall briefly explain.

The bank is constantly receiving cash from every person who keeps their cash with it. This occasions a constant fluctuation of payments, which of course must leave at all times a considerable sum of other people’s money in the bank; because it never is in advance to any one.

By long practice in the trade, this sum of money becomes determinate: let us call it the average-money in the hands of the bank. It is then with this average-money alone, that the bank can discount bills. Now if the trade of London does afford bills to be discounted at different dates within 60 days, sufficient to absorb the whole average-money of the bank, appropriated for discounting; this branch of business would not go forward with the celerity required for the trade of London, did the bank indulge merchants so far as to discount at a longer day.
