A child's game is carried out to its more imaginative consequences here as Elizabeth Coatsworth's rhymes pursue a little boy hither and yon. ""Where are you?"" they ask- underground like the moles?, with the spider in its web?, on a train?, flying in a plane? Mother has hidden her eyes the while and is glad when her child returns from wherever he's been. A well worn concept traditionally portrayed, but the enjoyable verses and pictures in green by Genevieve Vaughan-Jackson make a come and come again book.
