To continue the history of Miss Trotter's fifth and last play, _The Revolution in Sweden_ was at length brought out at the Queen's Theatre in the Haymarket, towards the close of 1704. It had every advantage which popular acting could give it, since the part of the hero, Count Arwide, was played by Betterton; that of Constantia, the heroine, by Mrs. Barry; Gustavus by Booth; and Christina by Mrs. Harcourt. In spite of this galaxy of talent, the reception of the play was unfavourable. The Duchess of Marlborough "and all her beauteous family" graced the theatre on the first night, but the public was cold and inattentive. Some passages of a particularly lofty moral tone provoked laughter. _The Revolution in Sweden_, in fact, was shown to suffer from the ineradicable faults which Congreve had gently but justly suggested. It was very long, and very dull, and very wordy, and we could scarcely find a more deadly specimen of virtuous and didactic tragedy. Catharine was dreadfully disappointed, nor was she completely consoled by being styled--by no less a person than Sophia Charlotte, Queen of Prussia--"The Sappho of Scotland." She determined, however, to appeal to readers against auditors, and when, two years later, after still further revision, she published _The Revolution in Sweden_, she dedicated it in most grateful terms to the Duke of Marlborough's eldest daughter, Henrietta Godolphin. How Miss Trotter came to be favoured by the Churchills appears from various sources to be this. Her brother-in-law, Dr. Inglis, was now physician-general in the army, and was in personal relations with the General. When the victory at Blenheim (August 1704) was announced, Catharine Trotter wrote a poem of welcome back to England. It is to be supposed that a manuscript copy of it was shown by Inglis to the Duke, with whose permission it was published about a month later. The poem enjoyed a tremendous success, for the Duke and Duchess and Lord Treasurer Godolphin "and several others" all liked the verses and said they were better than any other which had been written on the subject. George Burnet, who saw the Duke in Germany, reported him highly pleased with her--"the wisest virgin I ever knew," he writes. She now hoped, with the Duke's protection, to recover her father's fortune and be no longer a burden to her brother-in-law. A pension of £20 from Queen Anne gave her mother now a shadow of independence, but Catharine herself was wholly disappointed at that "settlement for my life" which she was ardently hoping for. I think that, if she had secured it, George Burnet would have come back from Germany to marry her. Instead of that he sent her learned messages from Bayle and from Leibnitz, who calls her "une Demoiselle fort spirituelle."
