The next year brings the production of Meyerbeer's "L'Africaine" at Covent Garden, and of Gounod's "Mock Doctor" by the Royal English Opera Company. At Her Majesty's, moreover, Ilma di Murska makes her first appearance as Lucia, and Giuglini is obliged to give up the season there through illness; while among the operatic stars of the year we find Wachtel, Graziani, Ronconi, and Mario. 1866 sees the _début_ at Covent Garden of Carlotta Patti, coming with a considerable reputation as a concert singer; while among the artists of the season are Naudin, and Nicolini, who afterwards married Adelina Patti. At Her Majesty's, the company includes Gordoni, Santley, Gassier, Tietjens, and Grisi, who is announced for a limited number of performances; while the Irish basso, Foley, makes a hit in "Il Seraglio" under the Italianised nomenclature, "Signor Foli." Next year, in which the death of Sir George Smart is chronicled, Covent Garden announces--on July 11--the first production of Gounod's "Romeo et Juliette" in an Italian version, with Mario and Patti in the title-_rôles_. At the rival house Mapleson has collected a fine company in Tietjens, Sinico, Gassier, Santley, Gordoni, Mongini, and two _débutantes_, Clara Kellogg, fresh from her American triumphs, and Christine Nillson, who makes her first appearance in "Traviata." On December 6 a terrible calamity occurred in the London musical world, with the burning down of Her Majesty's Theatre. At the beginning of the month, during a rehearsal of "Fidelio," Mapleson's insurance-agent called to complete the insurance of the house. Colonel Mapleson agreed to insure for £30,000; but as the costumier's list was not at hand, and the costumier himself was out at dinner, the agent suggested that the manager should give him £10 "on account," and thus keep the matter open till the following Monday, when he--the agent--would call again. Mapleson replied, jokingly, "There is no fear," and the agent left without the advance. At half-past eleven the same evening Mapleson, who was dining in St John's Wood, was called by an excited servant to look out of the window, and saw the sky red in the distance. Her Majesty's Theatre was on fire! The manager hurried to the scene of the conflagration, and found the house in full blaze. Without a moment's delay he despatched Mr Jarrett, his acting-manager, to Mr F. B. Chatterton, then the lessee of Drury Lane, to endeavour to secure that theatre from March till the end of July. It was of great importance that the emissary should reach Chatterton, who lived at Clapham, before that astute manager could learn of the fire; for had he been aware of Mapleson's extremity, he would, of course, have raised his terms accordingly.
