“That’s where the Equator’s gone, then,” he said.

“Has the Equator left the top of the volcano?” asked Nimbus excitedly.

“He has,” said Jack Frost. “He was just about to destroy this little boy when I stopped him. He’s afraid of me.”

“More than of any one else in the whole world,” said Nimbus. “But where do you suppose he is now?”

“I don’t suppose,” said Jack Frost; “I can only suspect.”

“And what do you suspect?”

“That he’s trailing the Evening Star, and if he finds her——”

“But he must not find her,” cried Nimbus.

“No,” said Jack Frost, “he must not.”

Out of the darkness above them shone a bright speck that grew larger and larger. As it drew nearer Billy saw that it was a Meteor, a new Meteor which he had never seen before.
