"What do you mean by your riddle?"

"You are very hard of comprehension to-day."

Albert leaned back in his sofa-corner and blew, as he loved to do, ring after ring in the air. Oswald was absorbed in thought. He considered whether he ought to confide to Timm the secret of the rendezvous to which he had been invited for to-night. At last he said, almost against his own conviction,

"I received a curious note from Primula to-day; I should like to see if you can make more of it than I can."

"Let us hear," replied Albert, lost in admiration of a huge blue ring which he had just accomplished.

Oswald read him the address to the young eagle, and the mysterious postscript. Albert started up from the sofa.

"Oswald, you are the luckiest dog alive!" he cried. "Why, the thing is evident. The young lady can be nobody else but the little Grenwitz. The girl has indeed ten times more sense and pluck than her chaste lover, who understands so little of the great art of seizing fortune by the hem of her garment. In good earnest, Oswald, the cards have been dealt so well for you, it could not be better. Of course, it will not be quite so easy to take the fortress. The Jager has evidently said more than she was authorized to say; but never mind that--you have the outworks, and if you do not get on soon it is your own fault. When are you to be at Primula's house?"

"At seven."

"It is five now; we have two hours time. Come, let us consider the plan of operation with the help of a good glass of wine. Charles the Bald has an excellent hock, and you must drink of that bravely, so that you may show yourself strong and hearty in your enterprise and permit no trace of sickly hesitation to be seen. Come!"
