The "Leaves from the Portfolio of a Manager," in the December Dublin University Magazine, disclose a number of interesting facts connected with Prynne's "Histriomastix," Milton's "Samson Agonistes," Hannah More's "Tragedies," Ireland's "Shakspeare Forgeries," and not a few very startling disclosures respecting the extraordinary emoluments of first class performers, from Roscius down to Jenny Lind. From this portion of our Manager's Portfolio we select the amusing recollections of Paganini in Ireland, twenty years ago:

"Catalani, Pasta, Sontag, Malibran, Grisi, Taglioni, Rubini, Mario, Tamburini, Lablache, cum multis aliis, have received their thousands, and tens of thousands: but, until the Jenny Lind mania left every thing else at an immeasurable distance, Paganini obtained larger sums than had ever before been received in modern times. He came with a prodigious flourish of trumpets, a vast continental reputation, and a few personal legends of the most exciting character. It was said that he had killed his wife in a fit of jealousy, and made fiddlestrings of her intestines; and that the devil had composed a sonata for him in a dream, as he formerly did for Tartini. When you looked at him, you thought all this, and more, very likely to be true. His talent was almost supernatural, while his 'get up,' and 'mise en scene,' were original and unearthly, such as those who saw him will never forget, and those who did not can with difficulty conceive. The individual and his performance were equally unlike anything that had ever been exhibited before. No picture or description can convey an adequate idea of his entrance and his exit. To walk simply on and off the stage appears a commonplace operation enough, but Paganini did this in a manner peculiar to himself, which baffled all imitation. While I am writing of it, his first appearance in Dublin, at the great Musical Festival of 1830, presents itself to 'my mind's eye,' as an event of yesterday. When he placed himself in position to commence, the crowded audience were hushed into a deathlike silence. His black habiliments; his pale, attenuated visage, powerfully expressive; his long, silky, raven tresses, and the flash of his dark eye, as he shook them back over his shoulders; his thin, transparent fingers, unusually long; the mode in which he grasped his bow, and the tremendous length to which he drew it; and, climax of all, his sudden manner of placing both bow and instrument under his arm, while he threw his hands behind him, elevated his head, his features almost distorted with a smile of ecstasy, and his very hair instinct with life, at the conclusion of an unparalleled fantasia! And there he stood, immovable and triumphant, while the theatre rang again with peals on peals of applause, and shouts of the wildest enthusiasm! None who witnessed this will ever forget it, nor are they likely again to see the same effect produced by mere mortal agency.

"The one string feat I always considered unworthy this great master of his art. It has been done by fifty others, and is at best but an imperfect exhibition on a perfect instrument; a mere piece of charlatanerie, or theatrical 'gag,' to use a professional term, sufficiently intelligible. There have been, and are, mighty musicians on the violin. Spagnoletti, De Beriot, Ole Bull (who according to some plays without any string at all), Sivori, Joachim, Ernst, Levey, &c. &c., are all in the list of great players; but there never was more than one Paganini; he is unique and unapproachable.

"In Dublin, in 1830, Paganini saved the Musical Festival, which would have failed but for his individual attraction, although supported by an army of talent in every department. All was done in first-rate style, not to be surpassed. There were Braham, Madame Stockhausen, H. Phillips, De Begnis, &c. &c., Sir G. Smart for conductor, Cramer, Mori, and T. Cooke for leaders, Lindley, Nicholson, Anfossi, Lidel Hermann, Pigott, and above ninety musicians in the orchestra, and more than one hundred and twenty singers in the chorus. The festival was held in the Theatre-Royal, then, as now, the only building in Dublin capable of accommodating the vast number which alone could render such a speculation remunerative. The theatre can hold two thousand six hundred persons, all of whom may see and hear, whether in the boxes, pit, or galleries. The arrangement was, to have oratorios kept distinct on certain mornings, and miscellaneous concerts on the evenings of other days. The concerts were crushers, but the first oratorio was decidedly a break down. The committee became alarmed; the expenses were enormous, and heavy liabilities stared them in the face. There was no time to be lost, and at the second oratorio, duly announced, there stood Paganini, in front of the orchestra, violin in hand, on an advanced platform, overhanging the pit, not unlike orator Henley's tub, as immortalized by the poet. Between the acts of the Messiah and the Creation, he fiddled 'the Witches at the Great Walnut Tree of Benevento,' with other equally appropriate interpolations, to the ecstatic delight of applauding thousands, who cared not a pin for Hadyn or Handel, but came to hear Paganini alone; and to the no small scandal of the select few, who thought the episode a little on the north side of consistency. But the money was thereby forthcoming, every body was paid, the committee escaped without damage, and a hazardous speculation, undertaken by a few spirited individuals, was wound up with deserved success.

"When the festival was over, the town empty, and a cannon-ball might have fired down Sackville-street, without doing much injury, Paganini was engaged by himself for a series of five performances in the theatre. For this he received £1,143. His dividend on the first night's receipts amounted to £330 (horresco referens)! without a shilling of outlay incurred on his part. He had the lion's share with a vengeance, as the manager cleared with difficulty £200. The terms he demanded and obtained were a clear two-thirds of each night's receipts, twenty-five guineas per night for the services of two auxiliaries, worth about as many shillings, the full value allowed for every free ticket, and an express stipulation that if he required a rehearsal on a dark morning, when extra light might be indispensable, the expense of candles should not fall on him—a contingency which by no possible contrivance could involve a responsibility exceeding five or six shillings."
