Herminie's rare beauty, as well as her dignity and refinement of manner had made a deep impression on the young duke, and the more he said to himself that he had, of course, seen this charming creature for the first and last time, the more he rebelled against the thought.

Besides, upon analysing or rather comparing his former fancies with his sudden but deep interest in Herminie, and discovering nothing like it in the past, Gerald asked himself, with no little uneasiness:

"What if I should be really caught this time?"

He had just asked himself this question when he was met by an officer of engineers wearing an army redingote without epaulettes, and a big straw hat.

"Why, it's Senneterre!" exclaimed this officer.

The young duke looked up and recognised Captain Comtois, one of his former comrades in the African army.

"How are you, my dear Comtois?" he exclaimed, cordially offering his hand. "I did not expect to see you here, though you are quite in your native element, I must admit," he added, with a glance at the fortifications.

"Yes, my dear fellow, we're making the earth fly and the work is advancing rapidly. I am general-in-chief of that army of labourers and masons you see over there. In Africa, we tore down walls; here, we build them up. Did you come over to look at the works? If you did, I'll show you about."

"A thousand thanks for your kind offer, my dear Comtois, I'll remind you of your promise some day soon."

"Very well, come and take breakfast with me any morning you like. I am living in camp over there. It will remind you of old times; you'll think you're in a Bedouin camp again. Oh, by the way, you remember Clarville, that young lieutenant of spahis who resigned in order that he might have the satisfaction of fighting Colonel Duval a year afterwards?"
