Answers to questions the very young may ask are given in an imaginative way by Mr. Schwartz, whose other junior science books It's Fun To Know Why and Through the Magnifying Glass have been good. Important queries like- Where does the rain go? or Why does the house shake? or What is a dream? are answered broadly enough to satisfy or to stimulate further good questions. A good family book, illustrated with Marc Simont's pointed drawings, in grey, blue and yellow.
