“Didn’t you fix a time to be recalled?” asked Maia. And when they said no, her beautiful smiling face suddenly looked grave.

“With whom have you left the charge of speaking the spell of recall?”

“I don’t know what you mean,” said Bernard. “What spell?”

“The one which enabled me to speak to you that day in the shallows,” said Maia. “Of course my sister explained to you that the spell which enables us to come at your call is the only one by which you can yourselves return.”

“She didn’t,” said Mavis.

“Ah, she is young and impulsive. But no doubt she arranged with someone to speak the spell and recall you?”

“No, she didn’t. She doesn’t know any land people except us. She told me so,” said Kathleen.

“Well, is the spell written anywhere?” Maia asked.

“Under a picture” they told her, not knowing that it was also written in the works of Mr. John Milton.

“Then I’m afraid you’ll have to wait ’til someone happens to read what is under the picture,” said Maia kindly.
