“ When he saw Dorothy and her companions the man asked, "What do you wish in the Emerald City?"
"We came here to see the Great Oz," said Dorothy.
The man was so surprised at this answer that he sat down to think it over.
"It has been many years since anyone asked me to see Oz," he said, shaking his head in perplexity. "He is powerful and terrible, and if you come on an idle or foolish errand to bother the wise reflections of the Great Wizard, he might be angry and destroy you all in an instant."
"But it is not a foolish errand, nor an idle one," replied the Scarecrow; "it is important. ”

“ But to those who are not honest, or who approach him from curiosity, he is most terrible, and few have ever dared ask to see his face. I am the Guardian of the Gates, and since you demand to see the Great Oz I must take you to his Palace. But first you must put on the spectacles."
"Why?" asked Dorothy.
"Because if you did not wear spectacles the brightness and glory of the Emerald City would blind you. Even those who live in the City must wear spectacles night and day. They are all locked on, for Oz so ordered it when the City was first built, and I have the only key that will unlock them." ”

“ Then they told him of the field mice, and how they had generously saved him from death; and the Cowardly Lion laughed, and said:
"I have always thought myself very big and terrible; yet such little things as flowers came near to killing me, and such small animals as mice have saved my life. How strange it all is! But, comrades, what shall we do now?"
"We must journey on until we find the road of yellow brick again," said Dorothy, "and then we can keep on to the Emerald City." ”
