"Nothing doing," remarked the young inventor with a short laugh. "Nixy on that jabbering."

"Boys! Mr. Damon! We're saved!" suddenly cried out Mr. Petrofsky.

"Bless my door knob! You don't say so!" gasped the odd man. "How? Has the Czar sent orders to release us."

"No, but somehow my Revolutionary friends have heard about my arrest, and they have arranged for our release—secretly of course. This guard is affiliated with the Nihilist group that got on the trail of my brother. He bribed the other guard to let him take his place for to-night, and now—"
