The pictures were superb—all the professor could have dreamed of, and more. “These, alone, will add greatly to the world’s riches,” he said, placing a trembling hand on Johnny’s shoulder.

“And when you show them,” Johnny grinned, “tell your audience they were taken by a ship’s watch, will you?”

“I take it,” said the professor with a laugh, “that you think you’d like to keep your feet on the ground, for a while!”

“Absolutely,” Johnny agreed. “And in more ways than one!”

Johnny went back to his old task of walking the deck that night. There would be no more tampering with hoists and motors if he knew anything about it—and he surely would know if it happened in the night.

For some unknown reason, this night was not like others that had passed. There seemed to be a spirit of unrest in the air.

Doris, too, felt it. Enveloped in a midnight-blue gown, she wandered out on deck.

“It’s ridiculous,” she exclaimed. “A grand night to sleep, but my eyes just will not stay closed!”

“There are ghosts in the air,” said Johnny. “I have felt them and almost heard their wings—or do ghosts have wings? There goes one now!”

Doris jumped as some swift, darting thing shot past her head.
