And Prince Zino--a musical Epicurean to his finger-tips, rejecting everything clumsy and indigestible in music,--Prince Zino, for whom Mozart is the only god of music and Rossini is his prophet--strokes his moustache, delighted, and calls "Bravo!" and della Seggiola bows.

The lesson continues to be quite interesting.

Signor Trevisiani, the barytone from Florence, sings something very depressing, with the refrain,--

'Maladetto sulla terra,
Condannato nel ceil sard.'

The little soprano sings, 'Plaisir d'amour,' and Zino perfectly, gravely, goes through a scale, swelling the notes, during which two sad facts are brought to light,--first, that he is the third barytone in the class,--della Seggiola had hoped for a tenor,--and, secondly, that he cannot read by note. Della Seggiola, however, praises the charming timbre of his voice, and asks if he may not send him a teacher to correct his defective reading; whereupon Fräulein Fuhrwesen declares herself ready to give the Prince lessons. He pretends not to hear this heroic proposition, seeming not even to perceive her; whereby he makes a mortal enemy of that extremely sensitive and irritable person.

The glory of the class is the closing performance,--the famous duet between Don Giovanni and Zerlina, rendered by Signor Trevisiani and Natalie Lipinski.

It would be difficult to imagine a more lugubrious Don Giovanni than the young man from Florence. He is freshly shaven, perhaps in honour of his part; his cheeks are covered with red scratches, like those of a German youth who bears about in his face the record of his bravery; his hair, artistically dishevelled about his forehead and ears, falls over his coat-collar at the back of his neck. Except for a grass-green cravat, he is dressed entirely in black, like the page in 'Marlbrook;' his costume, evidently provincial, comes from the same quarter of Paris that has produced his sisters' hats,--the Temple.

Much intimidated by his haughty Zerlina, his throat contracts so that his voice, naturally fine and resonant, comes from his dry lips hoarse and miserably thready. Although Natalie sings, as ever, in faultless time, the notes that should be in unison are far from sounding so, whereupon della Seggiola advises the singers to take each other's hands. Mademoiselle Lipinski edges away still farther from her Don Giovanni, and extends to him her finger-tips.

Della Seggiola makes them repeat the duo three times, does his best to make it go smoothly, gently entreats Zerlina to be more coquettish, orders Don Giovanni to be more seductive. In vain. Zerlina draws down the corners of her mouth and looks at the wall; Don Giovanni scratches his ear. The duo sounds worse and worse. Much irritated at this melancholy result, which she ascribes entirely to Signor Trevisiani's awkwardness, Natalie at last says crossly to the young Florentine, "I beg you not to torment me any more: it will never do!" Then across her shoulder to her cousin she explains, impatiently, "Zino, Signor Trevisiani is hoarse; you and I used to sing the duo together. Come, try it."

"If there is time," Zino says, with amiable readiness, taking his place beside his cousin.
