I shall not attempt to describe the strange sensations of Frederick on returning from the burgomaster's house It will have been seen from the glimpses we have had of him already, that he was of a quick and sensitive disposition, and that the chance of defeat in the approaching struggle would sting him into madness. He pictured to himself the ferocious joy of Castero on being declared the victor—the agony of Maïna—the misery of his own degradation; and there is no doubt if the mysterious Unknown, whose appearance he now felt certain was nothing but a dream, had visited him in propriâ personâ, that he would have accepted his terms—his soul for triumph over his enemy, for the possession of the girl he loved.

The morrow rose clear and cloudless. At the appointed hour Frederick took his violin, and prepared to set out. But just when he was opening the door, the man in the mantle—the same he had seen the day before—stood before him.

"You did not expect to see me," said the Unknown, following Frederick to the end of the room, where he had retreated. "I told you, nevertheless, that we should meet again," he added, placing himself face to face with the son of the brewer.

"Then it was no dream," murmured the youth, who appeared to have lost all his resolution.

"Certainly not," returned the stranger, looking sarcastically at Frederick from head to foot. "I promised you yesterday, on the banks of the lake, that you would find your fiddle unharmed, and that I would enable you to conquer your rival. But I don't feel that I am bound to do any thing of the kind for nothing; generosity was never my forte, and I have lived long enough among the burghers of Holland to insist on being well paid for every thing I do."

"Who are you, then; and what is it you want?" enquired the Dutch Orpheus, in an agitated voice.

"Who am I!" answered the man in the mantle, with all the muscles of his face in violent convulsions—"Who am I!—I thought I had told you yesterday when you asked me—I am your master. What do I want? I will tell you. But why do you tremble so? you were bold enough when we met. I saw the thought in your heart—if Satan should rise before me, and promise me victory over my rival at the price of my soul, I would agree to the condition!"

"Satan!—you are Satan!" shrieked Frederick, and closed his eyes in horror.

"Didn't you find me out on the side of the lake, when you told me you would exchange your salvation for years of love and glory. Yes, I am that King of Darkness—your master! and that of a great part of mankind. But, come; the hour is at hand—the Burgomaster and the Stadtholder await us. Do you accept the offer I make you?"

After a minute's hesitation, during which his features betrayed the force of the internal contest, the musician made his choice. He had not power to speak, but he raised his hand, and was on the point of making the cross upon his forehead, to guard him from the tempter, when Satan perceived his intention, and seized his arm.
