Yes, that's it! How did you find that out?

By the way, I checked on Amazon, and that set of books (the Junior Classics) came with Collier's Encyclopedia. Our set was the 1938 version. Someone is asking $200 for that set today - a set in fine condition.

There's another thing I remember from 'Vasilisa the Beautiful.' Baba Yaga mixes poppy seeds with dirt and orders the little girl to retrieve every tiny seed. The magic doll organizes an army of ants, who expertly get every seed out for her.
