"A drop of oil!" exclaimed the Tin Woodman.
"Dear me, how careless my valet must have
been in oiling me this morning. I'm afraid I
shall have to scold the fellow, for I can't be
dropping oil wherever I go."

"Never mind," said Dorothy. "Ojo seems glad
to have the oil, for some reason."

"Yes," declared the Munchkin boy, "I am
glad. For one of the things the Crooked Magician
sent me to get was a drop of oil from a live man's
body. I had no idea, at first, that there was such
a thing; but it's now safe in the little crystal
vial."

"You are very welcome to it, indeed," said
the Tin Woodman. "Have you now secured all
the things you were in search of?"

"Not quite all," answered Ojo. "There were five
things I had to get, and I have found four of
them. I have the three hairs in the tip of a
Woozy's tail, a six-leaved clover, a gill of water
from a dark well and a drop of oil from a live
man's body. The last thing is the easiest of all
to get, and I'm sure that my dear Unc Nunkie--and
good Margolotte, as well--will soon be restored to
life."
