There was a happy exchange of glances as she pressed the little prison into his hand. “It is yours forever,” she pledged under the sway of her rising emotions.

And he, accepting it with a warm heart, spoke thus in glowing words: “I accept the endless task and also pledge to the utmost of my power to keep any foe imprisoned that seeks to rob your life of any passing happiness.”

“Are we permitted to visit the interior apartments of this tower, even below us?” asked Mr. World wistfully.

“They are all doubly sealed. No one but an expert inventor, true and tried in our master’s service, ever passes through these secret chambers.”

“May we know what particular branch of work is done in this tower?”

“It is devoted alone to the invention and testing of weapons of warfare for the armies of our master, especially for the sharp-shooters stationed along the so-called King’s Highway.”
