That put the ball of merriment in motion again. One of the young ladies, a goddaughter of the hostess, carolled a stanza from a popular ditty. At first I thought it audacious that any one should sing in the presence of _La Diva_. It seemed sacrilege. But in another instant we were all at it, piping the chorus, and Patti leading off. The fun of the thing was infectious. The song finished, we ventured another, and Patti joined us in the refrains of a medley of music-hall airs, beginning with London's latest mania, "Daisy Bell, or a Bicycle Built for Two", and winding up with Chevalier's "Old Kent Road" and the "Coster's Serenade", Coborn's "Man That Broke the Bank at Monte Carlo", and somebody else's "Daddy Would n't Buy me a Bow-Wow." Patti turned with an arch look. "You will think our behaviour abominable." "No, I don't. I think it jolly. Besides, it's not everybody who has heard you sing comic songs." Her answer was a peal of laughter, and then she sat there, singing very softly a stanza of "My Old Kentucky Home", and as we finished the chorus she lifted a clear, sweet note, which thrilled us through and through and stirred us to excited applause. "What have I done?" Patti put the question with a puzzled air. The reply came from the adjoining library: "High E." One of our number had run to the piano. {69} Then I recalled what Sir Morell Mackenzie had told me a little while before he died. We were chatting in that famous room of his in Harley Street, and we happened to mention Madame Patti. "She has the most wonderful throat I have ever seen," said Sir Morell. "It is the only one I have ever seen with the vocal cords in absolutely perfect condition after many years of use. They are not strained, or warped or roughened, but as I tell you, they are perfect. There is no reason why they should not remain so ten years longer, and with care and health twenty years longer." Remembering this, I asked Patti if she had taken extraordinary care of her voice. "I have never tired it," said she; "I never sing when I am tired, and that means I am never tired when I sing. And I have never strained for high notes. I have heard that the first question asked of new vocalists nowadays is 'How high can you sing?' But I have always thought that the least important matter in singing. One should sing only what one can sing with perfect ease." "But in eating and drinking? According to all accounts, you are the most abstemious person in the world." "No, indeed! I avoid very hot and very cold dishes, otherwise I eat and drink whatever I like. My care is chiefly to avoid taking cold and to avoid indigestion. But these are the ordinary precautions of one who knows that health is the key to happiness." "And practising? Have you rigid rules for that? One hears of astounding exercise and self-denial." {70}
