"Aye, more than wonderful! I watched him intently," said the old man; "I noted with what marvelous facility he went from one string to the other. But however rapid, however difficult the composition, he steadily avoided one string; in fact, that string remained untouched during the entire hour he played for us." "Perhaps the composition did not call for its use," suggested Mildred, unconscious of any other meaning in the old man's observation, save praise for her lover. "Perhaps so, but the oddity impressed me; it was a new string to me. I have never seen one like it on a violin before." "That can scarcely be, for I do not remember of Signor Diotti telling me there was anything unusual about his violin." "I am sure it has a fifth string." "And I am equally sure the string can be of no importance or Angelo would have told me of it," Mildred quickly rejoined. "I recall a strange story of Paganini," continued the old man, apparently not noticing her interruption; "he became infatuated with a lady of high rank, who was insensible of the admiration he had for her beauty. "He composed a love scene for two strings, the 'E' and 'G,' the first was to personate the lady, the second himself. It commenced with a species of dialogue, intending to represent her indifference and his passion; now sportive, now sad; laughter on her part and tears from him, ending in an apotheosis of loving reconciliation. It affected the lady to that degree that ever after she loved the violinist." "And no doubt they were happy?" Mildred suggested smilingly. "Yes," said the old man, with assumed sentiment, "even when his profession called him far away, for she had made him promise her he never would play upon the two strings whose music had won her heart, so those strings were mute, except for her." The old man puffed away in silence for a moment, then with logical directness continued: "Perhaps the string that's mute upon Diotti's violin is mute for some such reason." "Nonsense," said the girl, half impatiently. "The string is black and glossy as the tresses that fall in tangled skeins on the shoulders of the dreamy beauties of Tuscany. It may be an idle fancy, but if that string is not a woven strand from some woman's crowning glory, then I have no discernment." "You are jesting, uncle," she replied, but her heart was heavy already. "Ask him to play on that string; I'll wager he'll refuse," said the old man, contemptuously. "He will not refuse when I ask him, but I will not to-night," answered the unhappy girl, with forced determination. Then, taking the old man's hands, she said: "Good-night, I am going to my room; please make my excuses to Signor Diotti and father," and wearily she ascended the stairs. Mr. Wallace and the violinist soon after joined old Sanders, fresh cigars were lighted and regrets most earnestly expressed by the violinist for Mildred's "sick headache."
