Of Banks and their Credit If a hundred economical gentlemen or proprietors of land, who put by every year money from their savings to buy land on occasion, deposit each one 10,000 ounces of silver with a goldsmith or banker in London, to avoid the trouble of keeping this money in their houses and the thefts which might be made of it, they will take from them notes payable on demand. Often they will leave their money there a long time, and even when they have made some purchase they will give notice to the banker some time in advance to have their money ready when the formalities and legal documents are complete.

In these circumstances the banker will often be able to lend 90,000 ounces of the 100,000 he owes throughout the year and will only need to keep in hand 10,000 ounces to meet all the withdrawals. He has to do with wealthy and economical persons; as fast as one thousand ounces are demanded of him in one direction, a thousand are brought to him from another. It is enough as a rule for him to keep in hand the tenth part of his deposits.

There have been examples and experiences of this in London.

Instead of the individuals in question keeping in hand all the year round the greatest part of 100,000 ounces the custom of depositing it with a banker causes 90,000 ounces of the 100,000 to be put into circulation. This is primarily the idea one can form of the utility of banks of this sort. The bankers or goldsmiths contribute to accelerate the circulation of money.

They lend it out at interest at their own risk and peril, and yet they are or ought to be always ready to cash their notes when desired on demand.

If an individual has 1000 ounces to pay to another he will give him in payment the banker's note for that amount. This other will perhaps not go and demand the money of the banker. He will keep the note and give it on occasion to a third person in payment, and this note may pass through several hands in large payments without any one going for a long time to demand the money from the banker. It will be only some one who has not complete confidence or has several small sums to pay who will demand the amount of it. In this first example the cash of a banker is only the tenth part of his trade.
