We bring to the attention of young readers a book translated into Russian for the first time by the greatest American storyteller, Lyman Frank Baum, better known to us as the author of “The Wizard of Oz.” The book about the incredible country of Mo was written a year before The Wizard and did not receive as much popularity. It is known mainly in English-speaking countries. This happened because the book turned out to be too difficult to translate - it is all filled with puns, its characters are too phantasmagorical and too unreal to be taken seriously.
