"But I want to help Ojo, who is my friend, to rescue the uncle whom he loves, and I'd kill a dozen useless butterflies to enable him to do that." The Tin Woodman sighed regretfully.
"You have kind instincts," he said, "and with a heart you would indeed be a fine creature.

I cannot blame you for your heartless remark, as you cannot understand the feelings of those who possess hearts.

I, for instance, have a very neat and responsive heart which the wonderful Wizard of Oz once gave me, and so I shall never--never--never permit a poor yellow butterfly to be tortured by anyone." "The yellow country of the Winkies," said Ojo sadly, "is the only place in Oz where a yellow butterfly can be found." "I'm glad of that," said the Tin Woodman.

"As I rule the Winkie Country, I can protect my butterflies." "Unless I get the wing--just one left wing--" said Ojo miserably, "I can't save Unc Nunkie." "Then he must remain a marble statue forever," declared the Tin Emperor, firmly.
Ojo wiped his eyes, for he could not hold back the tears.
"I'll tell you what to do," said Scraps.

"We'll take a whole yellow butterfly, alive and well, to the Crooked Magician, and let him pull the left wing off." "No, you won't," said the Tin Woodman.
