"Good-morning, papa!" called a gay young voice, and the subject of the conversation appeared in the door-way. Hans Wehlau junior was a slender and very handsome young fellow of twenty-four, with nothing in his exterior to suggest the dignity of the future professor. His straw hat, before he removed it, sat jauntily upon his thick, light brown hair, and his very becoming summer suit, with a 'turn-down' shirt collar, had an artistic, rather than a learned, air. His fresh, youthful face was lit up by a pair of laughing blue eyes, and altogether there was something so attractive and endearing about him that the Professor's evident paternal pride was very easy to understand. "Well, Head-over-heels, here you are!" he said, gayly. "I have been preparing your aunt for the turmoil that you carry with you wherever you go." "On the contrary, sir, I have grown monstrously sedate," Hans declared, illustrating his assertion by putting his arm around the waist of his aunt, who had just innocently set down her basket of keys, and waltzing with her around the room in spite of her struggles. "Let me alone, you unmannerly boy!" she said, out of breath, when at last he released her with a profound bow. "Forgive me, aunt, but it was the suitable preface to my errand. The kitchen department urgently requires your presence; and, as I like to make myself useful in a house, I offered to inform you of it." Her nephew's zeal in this respect seemed rather suspicious to the mistress of the house, who asked, "What were you doing in the kitchen?" "Good heavens! I was only paying my respects to old Gretel." "Indeed? And young Leni was not there?" "Oh, I had her presented to me, as I had not seen her before. It was my duty as one of the family. My tastes are very domestic." "My dear Hans," the Frau Burgomeisterin said, with decision, "I take no interest in your domestic tastes, and if I find them leading you into the kitchen, the doors will be locked in your face; remember that." She nodded to her brother-in-law, and sailed majestically out of the room. "Take care, take care!" said the Professor. "Favourite as you are with your aunt, there are certain points upon which she will have no jesting; and she is right. At all events, her mind must now be set at rest with regard to your despair, as she calls it. She clings obstinately to the idea that you are unhappy in your profession." "No, sir, I am not at all unhappy," the young man asserted, seating himself astride of a chair and looking cheerfully about him. "I never supposed you were. Such youthful nonsense is sure to vanish of itself as soon as one is occupied with graver matters." "Of course, papa," Hans assented, occupying himself for the time with rocking his chair to and fro, a proceeding which appeared to afford him great gratification.
