The real aim, of the story was to test the doctrine of “original sin” and human responsibility for the disordered volition coming under that technical denomination. Was Elsie Venner, poisoned by the venom of a crotalus before she was born, morally responsible for the “volitional” aberrations, which translated into acts become what is known as sin, and, it may be, what is punished as crime? If, on presentation of the evidence, she becomes by the verdict of the human conscience a proper object of divine pity and not of divine wrath, as a subject of moral poisoning, wherein lies the difference between her position at the bar of judgment, human or divine, and that of the unfortunate victim who received a moral poison from a remote ancestor before he drew his first breath? It might be supposed that the character of Elsie Veneer was suggested by some of the fabulous personages of classical or mediaeval story. I remember that a French critic spoke of her as cette pauvre Melusine. I ought to have been ashamed, perhaps, but I had, not the slightest idea who Melusina was until I hunted up the story, and found that she was a fairy, who for some offence was changed every Saturday to a serpent from her waist downward. I was of course familiar with Keats's Lamia, another imaginary being, the subject of magical transformation into a serpent. My story was well advanced before Hawthorne's wonderful “Marble Faun,” which might be thought to have furnished me with the hint of a mixed nature,--human, with an alien element,--was published or known to me. So that my poor heroine found her origin, not in fable or romance, but in a physiological conception fertilized by a theological dogma. I had the dissatisfaction of enjoying from a quiet corner a well-meant effort to dramatize “Elsie Veneer.” Unfortunately, a physiological romance, as I knew beforehand, is hardly adapted for the melodramatic efforts of stage representation. I can therefore say, with perfect truth, that I was not disappointed. It is to the mind, and not to the senses, that such a story must appeal, and all attempts to render the character and events objective on the stage, or to make them real by artistic illustrations, are almost of necessity failures. The story has won the attention and enjoyed the favor of a limited class of readers, and if it still continues to interest others of the same tastes and habits of thought I can ask nothing more of it.
