Oh dear. Aileen Fisher has written a text about a little girl standing on a mountain wondering ""How did it all happen?"" and getting various answers from various folks (""from an egg,"" says an old mountaineer; ""from a Word,"" says a black woman; from fire, says an Indian; from an explosion, says a boy); and Blair Lent has illustrated this wishy-washy paean to the wonderful American world with wishy-washy pictures which include double-page watercolors of the surf breaking on the shore, the desert at sundown, and a New England village in the snow. ""Wonderful world!"" is in fact the little girl's greeting to each of her informants-to-be--and one wonders who save a hippie grandmother would find any of this engaging.
