MY COVENT GARDEN SEASON--PATTI'S LONDON SILVER WEDDING--RETURN TO NEW YORK--DIFFICULTIES BEGIN--RIVAL REHEARSALS--GRAND OPERA AND OPERETTA. On my return to London I opened Covent Garden for a series of Italian Opera performances, in which Mdme. Patti was the principal prima donna, and but for Mdme. Patti's twice falling ill should certainly have made some money. On the opening night I was notified as late as seven o'clock that Mdme. Patti would be unable to appear in "La Traviata," having taken a severe cold. This was a dreadful blow to me.

Fohström, who afterwards made a very successful career under my management.

I ended my season about the third week of July, when Mdme. Patti appeared as "Leonora" in _Il Trovatore_, renewing the success which always attends her in that familiar impersonation. On this night, the final one of the season, Mdme. Patti concluded her 25th consecutive annual engagement at Covent Garden. Numbers of her admirers formed themselves into a committee for the purpose of celebrating the event by presenting her with a suitable memorial, which consisted of a very valuable diamond bracelet. At the termination of the opera I presented myself to the public, saying--
