themselves of the same expedient, and have issued their own promissory notes in payment of their expenses; a resource the more useful, because it is the only mode in which they are able to borrow money without paying interest, their promises to pay on demand being, in the estimation of the holders, equivalent to money in hand. The practical differences between such government notes and the issues of private bankers, and the further diversities of which this class of substitutes for money are susceptible, will be considered presently.
