"Hullo, here's the Inspecting Officer back again," he exclaimed.

"Yes, yes," returned Pernambouc. "Here's the launch. And his day's work finished, his duty performed, he went back to his dormitory like a well-disciplined 'convict.'"

The Commandant had also caught the hum of the approaching launch. He reached the jetty in time to receive the officer when he landed, and to learn that his instructions had been carried out, but that no trace of the fugitives had been seen.

"It's something very like witchcraft," exclaimed the Commandant as he left the jetty with the officer. "We haven't discovered anything either."

At that juncture the warder was not a little taken aback to see the launch put off from the jetty without apparently any crew being on board her. He shouted, called for help, and fired several shots at her on chance. The officers rushing up in haste could scarcely believe their own eyes.

Meantime Chéri-Bibi and the Nut had at last found each other, boarded the launch, and reached the open sea. The engine was running to perfection. They might consider themselves out of danger. Suddenly Chéri-Bibi exclaimed:

"The barque!"

This was the sailing ship whose business it was to convey the convicts to the various penitentiary establishments and to keep guard.

The coast was quite near. Nevertheless Chéri-Bibi and the Nut had barely time to run the launch aground before the boat which was lowered by the barque landed a body of warders who at once started firing on them.

"We've got 'em; we've got 'em," they bellowed.
