“Do you think it would be easy to find that locality again?”

“Oh, there’s the rub,” said Beere, rubbing his hands; “in my lifetime I have made six attempts and failed. But, of course, we traveled overland.”

The same thought came to each.

“Then you think the air-ship—on account of a better view of the earth, could locate it?”

“I do,” replied Nicodemus. “Now you have the whole thing in a nutshell, Frank. The moment I looked at your air-ship, I saw a possible way to visit the mysterious country and locate the Transient Lake.”

Frank Reade, Jr., seemed for a moment in a glow. His eyes shone like blazing stars, and his manner was all eagerness.

“By Jove, you have done it, Captain Nicodemus!” he declared. “I have been trying to decide upon a new trip with the Spectre, and to visit the Transient Lake is just the thing. It promises eager anticipation, excitement and thrilling adventure.”

The captain leaned over the table.

“You will go?” he asked, tensely.

“Yes,” replied Frank.
