In his introduction to this volume, I. O. Evans says of removing Le Humbug and La Famille Raton:

• "... That volume (Hier et Demain) forms the basis of the present collection of short stories and oddments, hitherto, so far as I can ascertain, unpublished in Britain. Two stories included in the original volume have, however, been omitted as lacking in general interest, and have been replaced by others culled from various sources.
  One of the omissions, La Famille Raton (this could perhaps best be translated as "Mr Rat and his Family") seems to be a fairy-story, but it is so absurdly fantastic that one cannot be certainwhether Verne meant it "seriously" as an entertainment for children or simply as a burlesque for theamusement of sardonic adults: it appeared inthe figaro illustre for January 1891.
  The title of the other, Le Humbug, needs no translation: this is a fierce satire on a type of character whom the author disliked intensely, the boastful mendacious American "go getter"; its hero is a caricature of a super-Barnum. written about, 1893, it never appeared before Verne's death; it may, indeed, not have been written with a view to publication at all-its author may simply have been "letting off steam."
  ............
  Two of his stories ... were posthumouly published, but whether their survival was due to deliberate intent or by inadvertence is not clear. As regards Le Humbug, inadvertence seemsthe more probable....."

Some of the above stories have been published separately.

Two of the village's children, Joseph Müller and Betty Clère find themselves a part of this register along with 14 other children.

With his newfound freedom, Jean returns back to his village to see if he can claim the woman he has always loved, Marguerite.
