Irving was impressed by the small, isolated riverbank communities and wrote: "The almighty dollar, that great object of universal devotion throughout our land, seems to have no genuine devotees in these peculiar villages; and unless some of its missionaries penetrate there, and erect banking houses and other pious shrines, there is no knowing how long the inhabitants may remain in their present state of contented poverty." It should be noted that Ben Jonson had used the term "almighty gold" in his "Epistle to Elizabeth, Countess of Rutland," which he wrote in 1616.
