"Oh, very well, then, so long as Joe is willing. What do you say, Joe?" and La Tour turned to the taciturn Indian.

"Joe say all right," was the laconic response, at which Raoul clapped his hands gleefully.

They set off the same night. Fortunately it was both dark and windy, so that there was all the less danger of their movements being seen or heard. But they must needs exercise the utmost caution, for Charnace had many Indians in his service, and they would no doubt be acting as scouts and sentinels in the neighbourhood of the fort.

Joe led the way with amazing dexterity, stepping over the ground as silently as a serpent, and the other two followed, doing their best to imitate him. Several times he stopped short, peered eagerly into the darkness, listened intently for a moment, and then, muttering something which Raoul could not catch, changed his course to right or left.

"JOE LED THE WAY."

Once the sound of voices came out of the night to them, and Raoul's heart throbbed wildly. He was not so much afraid of being captured as he was that they should be balked in their purpose, and that the supply ship, coming up without warning, would fall into Charnace's hands. They were evidently passing through the line of their enemy's sentinels, and in peril of being betrayed by the slightest sound. Very cautiously did Joe make his way, now turning this way and now that, while Raoul and Jean kept so close that they could almost touch him. It was trying work, that told upon muscles and nerve, yet Raoul held his own with the men all right, and certainly moved as silently as Jean, even if he could not quite equal Joe.

At last they seemed to be getting well away from the fort, and into safer ground, when suddenly a dark form rose in front of them.
