"What in the name of all the witches of Salem has got into that piano!" cried Mr. Burleigh, bursting into the parlor from the office, with his pen stuck behind his ear, and his hair brushed up perpendicularly. "There's sorcery in the air. I'm practised upon--Keep still? No, not if I was nailed up in one of the soldier's 'wooden overcoats.' The world is transformed, transfigured, transmogrified, and 'things are not what they seem!' Here's a blooming girl who'll dance with me," and he seized the hand of a white-haired old lady who yielded to the contagion so far as to take a place in the line beside her granddaughter. Indeed, in a few moments, all who had been familiar with the pastime in their youth, caught the joyous infection, and lengthened out the lines, each new accession being greeted with shouts and laughter. The scene approached in character that described by Hawthorne as occurring in the grounds of the Villa Borghese when Donatello, with a simple "tambourine," produced music of such "indescribably potency" that sallow, haggard, half-starved peasants, French soldiers, scarlet-costumed contadinas, Swiss guards, German artists, English lords, and herdsmen from the Campagna, all "joined hands in the dance" which the musician himself led with the frisky, frolicsome step of the mythical faun. In the latter instance it was a contagious, mad excitement easily possible among hot-blooded people and wandering pleasure-seekers, the primal laws of whose being are impulse and passion. That the joyous exhilaration which filled Mr. Burleigh's parlor was akin to the wild, half pagan frenzy that the great master of fiction imagined as seizing upon the loiterers near the Villa Borghese cannot be denied. Both phases of excitement would spring naturally from the universal craving for pleasurable life and activity. The one, however, was a rank growth from a rank soil--the passionate ebullition of passion-swayed natures; the other was inspired by the magnetic spirit of a New England maiden, who, by some law of her nature or consecration of her life, devoted every power of her being to the vivifying of others, and the frolic she had instigated was as free from the grosser elements as the tossing wild flowers of her native hills. With the exception perhaps of Van Berg, she had impressed every one as possessing a peculiarly sunny temperament. Be this as it may, it certainly appeared true that she found her happiness in enlivening others; and it is difficult even to imagine how much a gifted mind can accomplish in this respect when every faculty is devoted to the ministry of kindness. This view of Miss Burton's character would account in part, but not wholly, for the power she exercised over others. Van Berg thought he at times detected a suppressed excitement in her manner. A light sometimes flickered in her deep blue eyes that might have been caused by a consuming and hidden fire, rather than by genial and joyous thoughts.
