Miss Brabazon having come to the close of a complicated and dreary sonata, I heard Margrave abruptly ask her if she could play the Tarantella, that famous Neapolitan air which is founded on the legendary belief that the bite of the tarantula excites an irresistible desire to dance. On that highbred spinster's confession that she was ignorant of the air, and had not even heard of the legend, Margrave said, "Let me play it to you, with variations of my own." Miss Brabazon graciously yielded her place at the instrument. Margrave seated himself,--there was great curiosity to hear his performance. Margrave's fingers rushed over the keys, and there was a general start, the prelude was so unlike any known combination of harmonious sounds. Then he began a chant--song I can scarcely call it--words certainly not in Italian, perhaps in some uncivilized tongue, perhaps in impromptu gibberish. And the torture of the instrument now commenced in good earnest: it shrieked, it groaned, wilder and noisier. Beethoven's Storm, roused by the fell touch of a German pianist, were mild in comparison; and the mighty voice, dominating the anguish of the cracking keys, had the full diapason of a chorus. Certainly I am no judge of music, but to my ear the discord was terrific,--to the ears of better informed amateurs it seemed ravishing. All were spellbound; even Mrs. Poyntz paused from her knitting, as the Fates paused from their web at the lyre of Orpheus. To this breathless delight, however, soon succeeded a general desire for movement. To my amazement, I beheld these formal matrons and sober fathers of families forming themselves into a dance, turbulent as a children's ball at Christmas; and when, suddenly desisting from his music, Margrave started up, caught the skeleton hand of lean Miss Brabazon, and whirled her into the centre of the dance, I could have fancied myself at a witch's sabbat. My eye turned in scandalized alarm towards Mrs. Poyntz. That great creature seemed as much astounded as myself. Her eyes were fixed on the scene in a stare of positive stupor. For the first time, no doubt, in her life, she was overcome, deposed, dethroned. The awe of her presence was literally whirled away. The dance ceased as suddenly as it had begun. Darting from the galvanized mummy whom he had selected as his partner, Margrave shot to Mrs. Poyntz's side, and said, "Ten thousand pardons for quitting you so soon, but the clock warns me that I have an engagement elsewhere." In another moment he was gone. The dance halted, people seemed slowly returning to their senses, looking at each other bashfully and ashamed. "I could not help it, dear," sighed Miss Brabazon at last, sinking into a chair, and casting her deprecating, fainting eyes upon the hostess. "It is witchcraft," said fat Mrs. Bruce, wiping her forehead.
