Canolles removed his eyes from the little white château, upon which he had kept them fixed, to the fortress which was to be his abode. He saw in the first place, on the other side of a swiftly flowing arm of the river, a ferry-boat, and beside it a guard of eight men and a sergeant. Behind them were the outworks of the citadel.

"Ah!" said Canolles to himself, "I am expected, it seems, and due precautions are taken.—Are those my new guards?" he asked Barrabas, aloud.

"I would be glad to answer monsieur's question intelligently; but really I have no idea."

At that moment, after exchanging signals with the sentinel on duty at the entrance to the fortress, the eight soldiers and the sergeant entered the ferry-boat, crossed the Garonne, and stepped ashore just as Canolles stepped to the ground.

Immediately the sergeant, seeing an officer, approached him and gave the military salute.

"Have I the honor of addressing Monsieur le Baron de Canolles, captain in the Navailles regiment?" he asked.

"Himself," replied Canolles, marvelling at the man's politeness.

The sergeant turned to his men, ordered them to present arms, and pointed with the end of his pike to the boat. Canolles took his place between his two guards, the eight men and the sergeant embarked after him, and the boat moved away from the shore, while Canolles cast a last glance at Cambes, which was just passing out of sight behind some rising ground.

The island was almost covered with scarps, counter-scarps, glaces, and bastions; a small fort in reasonably good condition overlooked all these outworks. The entrance was through an arched gateway, in front of which a sentinel was pacing back and forth.

"Qui vive?" he cried.
