"She has been eaves-dropping," exclaimed the Countess Podstadsky, contemptuously.

"Yes," said Arabella, with perfect equanimity. "I have enjoyed the privilege of witnessing this charming scene. You, madame, have acted incomparably, but your son has not sustained you. The role you have given him is inappropriate. To ask of him to play the repentant sinner, is simply ridiculous. Count Podstadsky is a gentleman, and has no taste for idyls."

"Who is this woman?" asked the old countess.

Her son had regained all his self-possession again. He approached Arabella, and, taking her hand, led her directly up to his mother.

"My mother, I beg to present to you the Countess Baillou, the lady-patroness of the ball I give to-night."

The old countess paid no attention to Arabella's deep courtesy. She was too much in earnest to heed her.

"Will you come, Carl? Every moment is precious."

"My dear lady," exclaimed Arabella, "you forget that not only the aristocracy of Vienna, but the emperor himself, is to be your son's guest to-night."

"Do not listen to her, my son," cried the wretched mother. "Her voice is the voice of the evil spirit that would lure you on to destruction.

Carl! Carl!" cried she, laying her vigorous grasp upon his arm, "be not so irresolute! Come, and prove yourself to be a man!"

"Ay!" interposed Arabella, "be a man, Carl, and suffer no old woman to come under your own roof and chide you as if you were her naughty boy.

What business, pray, is it of this lady's, where you gather your riches?

And what to the distinguished Podstadsky are the clamors of two unnatural parents, who have long since lost all claim to his respect?"

"Carl! Carl!" shrieked the mother, "do not heed her. She is an evil spirit. Come with me."

There was a pause. Arabella raised her starry eyes, and fixed them with an expression of passionate love upon the count. That simulated look sealed his fate.

"No, mother, no. Importune me no longer, for I will not leave Vienna.

Enough of this tragi-comedy--leave me in peace!"

Arabella flung him a kiss from the tips of her rosy fingers.

"Spoken like a man, at last," said she.

For a while not a word was beard in that gorgeous room, where the chandeliers flung their full red glare upon the group below--the white-haired mother-the recusant son--the beautiful enchantress--whose black art had just sundered them forever.

At length she spoke, that broken-hearted mother, and her voice was hollow as a sound from the grave.

"Thou hast chosen. God would have rescued thee, but thou hast turned away from His merciful warning! Farewell, unhappy one, farewell!"

She wrapped her dark mantle around her, and concealed her face again in the veil.

Her son dared not offer his hand, for evil eyes were upon him, and he allowed her to depart without a word. Slowly she traversed the scene of sinful splendor, her tall, dark figure reflected from mirror to mirror as she went; and before the receding vision of that crushed and despairing mother the lights above seemed to pale, and the gilding of those rich saloons grew dim and spectral.

Farther and farther she went, Podstadsky gazing after her, while Arabella gazed upon him. She reached the last door, and he started as if to follow. His tempter drew him firmly back, and calmed his agitation with her magic smile.

"Stay, beloved," said she, tenderly. "From this hour I shall be mother, mistress, friend--all things to you!"

He clasped her passionately to his heart, sobbing, "I wish for nothing on earth but your love, the love which will follow me even to the scaffold!"

"Pshaw!" exclaimed Arabella, "what an ugly word to whisper to these beautiful rooms! Look here, Carl, the diamonds we own in common are worth half a million. We must do a good business to-night. When the emperor has retired, the hostess will have a right to preside over the faro table, and you know that my cards never betray me."

"I know it, my enchantress," cried Carl, kissing her. "Let us make haste and grow rich. I would go anywhere with you, were it even to Switzerland."

"But not as a peasant, Carl. First, however, we must have our millions.

Now, be reasonable to-night, and don't play the Italian lover. Colonel Szekuly is desperately enamored of me, and he will be sure to sit next to me at the faro-table. The place he covets shall cost him a fortune."

At that moment the steward entered the room.

"A message from the emperor, my lady."

"What can it be?"

"His majesty regrets that he cannot keep his engagement this evening with Count Podstadsky."

"This is a disappointment. What else?" asked the countess, as the servant still stood there.

"Several other excuses, my lady. The two Princesses Lichtenstein, Countess Thun, and Princess Esterhazy also have sent apologies."

"Very well, Duval. Go, for the guests will be corning."

The steward went, and the pair looked at each other in anxious silence.

Both were pale, both were frightened.

"What can it mean? What can it mean?" faltered the countess.

"What can it mean?" echoed the count, and he stared, for again he thought that he saw his mother's shadow darkening the splendor of those princely halls, whose lights were flickering as though they were about to be extinguished and leave the guilty accomplices in irretrievable darkness.

"Arabella, something threatens us!" whispered Podstadsky.

"Nonsense! Our guests are arriving." said she, rallying "Cour age, Carl, courage! A smooth brow and bright smile for the aristocratic world, Count Podstadsky!"

The doors opened, and crowds of splendid women, accompanied by their cavaliers, floated in toward the lady patroness, who received them all with bewitching grace, and won all hearts by her affability.

CHAPTER CLI.

THE TWO OATHS.

"Already, beloved? Think that for three long weeks I have not seen you, Gunther! It is so early: no one misses me in the house, for my father returns from his bank at nine only. Who knows when we shall meet again?"

"To-morrow, my Rachel, if you will permit me to return, and every morning at this hour, I shall be here behind the grove, waiting for my angel to unlock the gates of Paradise, and admit me to the heaven of her presence."

"I will surely come! Nor storm nor rain shall deter me. Here, in this pavilion, we are secure from curious eyes. God alone, who blesses our love, shall see into our hearts!"

"Oh, Rachel, how I honor and love your energetic soul! When I am with you, I fear nothing. But away from the influence of those angelic eyes, I tremble and grow faint."

"What do you fear, Gunther?"
