“The cyclone had set the house down gently, very gently – for a cyclone—in the midst of a country of marvelous beauty. There were lovely patches of green sward all about, with stately trees bearing rich and luscious fruits. Banks of gorgeous flowers were on every hand, and birds with rare and brilliant plumage sang and fluttered in the trees and bushes. A little way off was a small brook, rushing and sparkling along between green banks, and murmuring in a voice very grateful to a little girl who had lived so long on the dry, gray prairies.”
“When Dorothy stood in the doorway and looked around, she could see nothing but the great gray prairie on every side. Not a tree nor a house broke the broad sweep of flat country that reached to the edge of the sky in all directions. The sun had baked the plowed land into a gray mass, with little cracks running through it. Even the grass was not green, for the sun had burned the tops of the long blades until they were the same gray color to be seen everywhere. Once the house had been painted, but the sun blistered the paint and the rains washed it away, and now the house was as dull and gray as everything else.”
“I cannot understand why you should wish to leave this beautiful country and go back to the dry, gray place you call Kansas.""That is because you have no brains," answered the girl. "No matter how dreary and gray our homes are, we people of flesh and blood would rather live there than in any other country, be it ever so beautiful. There is no place like home." The Scarecrow sighed."Of course I cannot understand it," he said. "If your heads were stuffed with straw, like mine, you would probably all live in beautiful places, and then Kansas would have no people at all. It is fortunate for Kansas that you have brains.”
“I think,' said the little Queen, smiling, 'that your friend must be the richest man in all the world.' 'I am,' returned the Scarecrow; 'but not on account of my money. For I consider brains to be far superior to money, in every way. You may have noticed that if one has money without brains, he cannot use it to advantage; but if one has brains without money, they will enable him to live comfortably to the end of days.' 'At the same time,' declared the Tin Woodman, 'you must acknowledge that a good heart is a thing that brains cannot create, and that money cannot buy. Perhaps, after all it is I who am the richest man in all the world.' 'You are both rich, my friends,' said Ozma gently; 'and your riches are the only riches worth having - the riches of content!' - The Marvellous Land Of Oz by L. Frank Baum pg 192 chapter 24”
“It was Toto that made Dorothy laugh, and saved her from growing as gray as her other surroundings. Toto was not gray; he was a little black dog, with long silky hair and small black eyes that twinkled merrily on either side of his funny, wee nose. Toto played all day long, and Dorothy played with him, and loved him dearly.”
“…and the next moment all of them were filled with wonder. For they saw, standing in just the spot the screen had hidden, a little old man, with a bald head and a wrinkled face, who seemed to be as much surprised as they were.”
“For although I feel that I know a tremendous lot, I am not yet aware how much there is in the world to find out about. It will take me a little time to discover whether I am very wise or very foolish" - Jack Pumpkinhead - The Marvellous Land Of Oz by L. Frank Baum pg 20 chapter 2”
