But the art and mystery of banks is a wonderful improvement on that. It is established on the principle that “private debts are a public blessing”; that the evidences of those private debts, called bank notes, become active capital, and aliment the whole commerce, manufactures, and agriculture of the United States. Here are a set of people, for instance, who have bestowed on us the great blessing of running in our debt about two hundred millions of dollars, without our knowing who they are, where they are, or want property they have to pay this debt when called on; nay, who have made us so sensible of the blessings of letting them run in our debt, that we have exempted them by law from the repayment of these debts beyond a given proportion (generally estimated at one-third).
