The Wizard of Oz by Lynam Frank Baum Chapter 11 Page 3

There was a soldier before the door, dressed in a green uniform and wearing a long green beard.

“Here are strangers,” said the Guardian of the Gates to him, “and they demand to see the Great Oz.”

“Step inside,” answered the soldier, “and I will carry your message to him.”

So they passed through the Palace Gates and were led into a big room with a green carpet and lovely green furniture set with emeralds. The soldier made them all wipe their feet upon a green mat before entering this room, and when they were seated he said politely:

“Please make yourselves comfortable while I go to the door of the Throne Room and tell Oz you are here.”
