“I gave you no promise, except that I would not run away, and I have not done so. I now ask your permission to depart.”

“You said that I might accompany you to the fort.”

“Oh, if you have the courage, yes,” replied the girl, carelessly.

They walked on together through the dense alleys of vegetation, and finally came to an opening which showed them a sandy plain, and across it the strong white stone walls of the fort, facing the wide river, and behind it the blue background of Lake Nicaragua.

Not a human form was visible either on the walls or on the plain. Fort San Carlos, in spite of the fact that it bristled with cannon, seemed like an abandoned castle. The two stood silent for a moment at the margin of the jungle, the young officer running his eye rapidly over the landscape, always bringing back his gaze to the seemingly deserted stronghold.

“Your three hundred and forty men keep themselves well hidden,” he said at last.

“Yes,” replied the girl, nonchalantly, “they fear that if they show themselves you may hesitate to attack a fortress that is impregnable.”

“Well, you may disabuse their minds of that error when you return.”

“Are you going to keep my stiletto?” asked the girl, suddenly changing the subject.

“Yes, with your permission.”
