n these first few chapters the main thrusts and themes of the novel are established. Dorothy is a sweet and innocent child full of mirth and joy, exemplified by her delight in her free-spirited dog Toto. She makes an indelible impact upon the land of Oz through the killing of the Wicked Witch of the East, although she is loath to take responsibility for it. Although Kansas is dreary and deadening, she cannot help but desire above everything else to return to her home. Her journey to the great Wizard whom she is told will help her is not a solitary one, however, for the good-natured Scarecrow makes his appearance as her first companion. His wish for brains is in contrast to the wise statements he frequently makes; even young readers will note that he does indeed have "brains" in his straw head.
