“ In came the Chief Steward, trying not to show the Nome King how frightened he was.
"Send the Chief Counselor here!" shouted the angry monarch.
Kaliko ran out as fast as his spindle legs could carry his fat, round body, and soon the Chief Counselor entered the cavern. The King scowled and said to him:
"I'm in great trouble over the loss of my Magic Belt. Every little while I want to do something magical, and find I can't because the Belt is gone. That makes me angry, and when I'm angry I can't have a good time. Now, what do you advise?" ”

“ To be angry once in a while is really good fun, because it makes others so miserable. But to be angry morning, noon and night, as I am, grows monotonous and prevents my gaining any other pleasure in life. ”

“ Indeed, Ozma and Dorothy had both almost forgotten that such a person as the Nome King yet lived under the mountains of the Land of Ev—which lay just across the deadly desert to the south of the Land of Oz.
An unsuspected enemy is doubly dangerous. ”
