The precariousness of its value and the uncertainty of its fate continually operate, night and day, to produce this destructive effect. Having no real value in itself it depends for support upon accident, caprice, and party; and as it is the interest of some to depreciate and of others to raise its value, there is a continual invention going on that destroys the morals of the country.
