Her appeal was answered unexpectedly. A tall, plumed figure dashed into the room; a vigorous arm was thrown around her waist, and she was lifted from her feet. Her unknown preserver, unimpeded by her light weight, passed into the corridor with a fleet step. The grand staircase was already on fire, but, drawing his furred cloak closely around her, the stranger dashed through the flames, and bore her out into the court yard. Almost before she knew it, she was sitting behind him on a fiery steed. The rider gave the animal the spur, and he dashed through the gate, followed by a hundred wild Cossacks, shouting and yelling in the frenzy of their triumph.

Gratitude for an escape from a dreadful death was now banished from Alvina's mind by the fear of a worse fate at the hands of these wild men.

"You have saved my life," she said to her unknown companion; "do not make that life a curse. Take pity on an unfortunate and sorely persecuted girl. I have no ransom to pay you; but free me, and you will earn my daily prayers and blessings."

"Fear nothing," answered a deep and manly voice. "No harm is intended thee; no harm shall befall thee. I swear it on the word of a Cossack chieftain."

Alvina was tranquillized at once by the evident sincerity of the assurance.

"You are alone now in the world," pursued the stranger "I strove to save your bridegroom, but he fell before I reached him."

"I loved him not," answered Alvina, coldly; "I mourn him not."

"You may hate me for the deed," said the stranger, "and I would fain escape that woe; but here I vouch it in the face of heaven, Count Willnitz fell by my hand. My sabre clove him to the teeth. Years had passed, but I could not forget that he once laid the bloody scourge upon my back."

"Alexis!" cried Alvina, now recognizing her preserver.

"Yes, dear but unfortunate girl," cried the Cossack leader, turning and gazing on the young girl, "I feel that thou art lost to me forever. I have slain thy father. Love for thee should have stayed my hand; but I had sworn an oath of vengeance, and I kept my vow."
