The young man could not refrain from admiring, in his heart, the cool certainty with which the Canadian uttered so monstrous an opinion; but at this moment the prisoners heard a gentle sound near them.

"Silence!" Bright-eye commanded.

They listened attentively. A harmonious voice then sang to a melody, full of gentleness and melancholy, the exquisite Blackfoot song beginning with the verses:—

"I confide to you my heart, in the name of the Master of Life; I am unhappy, and no one takes pity on me, yet the Master of Life is great in my sight."

"Oh!" the Count muttered joyously, "I recognise that voice, my friend."

"And I too, by Jupiter! It is Prairie-Flower's."

"What does she say?"

"It is a warning she gives us."

"Do you believe so?"

"Prairie-Flower loves you, Mr. Edward."
