In one of father La Fontaine's books, may be found a description of a lovely valley, the residence of a beautiful and modest maiden, and of the heroine of this Arcadia he writes: "There stands our heroine, as lovely as the valley, her home, and as virtuous and good as her mother, who has devoted a lifetime to the education of her daughter." But with the history of this maiden he weaves the workings of an evil genius, which in the end is triumphant; for even the pure are contaminated after they arrive at that period when they consider that vice has its virtues.
