Slade shook his head.

"I'm sorry I can't help you there, sir."

"Dr. Trendon said that you knew nothing about Edwards."

"Edwards?" repeated Slade inquiringly. His mind, still absorbed in the events which he had been relating, groped backward.

Trendon came to his aid. "Barnett asked you about him, you remember. It was when you recovered consciousness. Our ensign. Took over charge of the Laughing Lass."

"Oh, of course. I was a little dazed, I fancy."

"We put Mr. Edwards aboard when we first picked up the deserted schooner," explained the captain.

"Pardon me," said the other. "My head doesn't seem to work quite right yet. Just a moment, please." He sat silent, with closed eyes. "You say you picked up the Laughing Lass. When?" he asked presently.

"Four--five--six days ago, the first time."

"Then you put out the fire."
