"Mary Louise and Jean and Alec and Jack with old Barbara hitched to a blue caravan, went caravaning over hills and down hills until they came to the dark blue waters of Wesalmacoon Lake. They had adventures by the way, for they met the Princess Onadagin; they heard the music of the Canadian fairies, and they lost Barbara. They met queer. cross, and friendly Jimmie Tipperary, too, and they came home to form The Blue Caravan Club and to plan adventures for another holiday. Simply written and well illustrated in line."
