"Article 12.--Should Mr. Mapleson fail to make such deposit in full by the day named Madame Patti shall be at liberty at any time afterwards, and notwithstanding any negotiation, withdrawal of notice, waiver, extension of time for depositing, or acceptance of part payment of such Two thousand pounds to put an end to this Engagement by lodging with Mr. Mapleson's Solicitors, Messrs. J. and R. Gole in London, a letter signed by her, announcing her determination of this Engagement; and thenceforth this Engagement shall be at an end except so far as regards the Agreement next following, that is to say, That on such failure and determination Mr. Mapleson shall, and he hereby agrees to pay to Madame Patti on demand the sum of Four thousand pounds as and for compensation to her for expenses incident to this Engagement and for loss of time in procuring other engagements of an equal character. "ADELINA PATTI." About the sum payable per night to Mdme. Patti by the terms of the above agreement I say nothing. Five hundred pounds a night was only half what I had paid her in the United States; and soon afterwards at Her Majesty's Theatre I myself offered to give the famous vocalist six hundred and fifty per night. The sting of the contract lies for the manager, pecuniarily speaking, in the clause which empowers the singer to declare herself ill at the last moment, while guaranteeing her against all the consequences sure to arise from her too tardy apology. The manager has suddenly to change the performance, and, worse by far, to incur the charge of having broken faith with the public; for however precisely the certificate of indisposition may be made out, there are sure to be some knowing ones among the disappointed crowd who will whisper, as a great secret known to them alone, that the prima donna has not been paid, and that the certificate is all a sham. What an unfair clause, too, is that by which, if the manager does not pay in advance to the prima donna at the exact time prescribed the whole of the sum payable to her for all the performances she binds herself to give, he will by such failure render himself liable for the entire sum without the prima donna on her side being called upon to sing at all.
