Mimi, who was Alberich's brother, was the best smith in all this swarm
of black slaves.

Alberich forced Mimi to make for him a strange wishing-cap.

It was made of woven steel.

Mimi had to make it just as Alberich said, but Mimi did not know how it
was to be used. When it was finished, Mimi feared it had some
wonderful power, and he did not want Alberich to have it.

He wished he might keep it for himself.

He had worked hard to make it.

"Give me that helmet," said Alberich. "I want you to know, Mimi, that
everything in this cave belongs to me!"

Mimi had to give it up.

Alberich put it on his head. "Now I shall see what magic there is in
this wishing-cap. Come, Night and Darkness!" he called. "Make me so no
one can see me!"

In an instant he was gone, and there was only a cloud of smoke where he
had stood.

"Now, Mimi!" he called, "look sharp! Can you see me?"

"No," gasped Mimi. "I cannot see you at all."
