"The Substance of a Dream" is half a love-story, and half a fairy tale: as indeed every love-story is a fairy tale. Because, although that unaccountable mystery, the mutual attraction of the sexes, is the very essence of life, and everything else merely accidental or accessory, yet only too often in the jostle of the world, in the trough and tossing of the waves of time, the accidental smothers the essential, and life turns into a commonplace instead of a romance. And so, like every other story, this little story will perhaps be very differently judged, according to the reader's sex.
