The result of this is great activity among English composers who, stimulated by Mr. Rosa's efforts, are having a race in writing such works, and are repaid for their pains by finding a home for their musical inventions. Operas like Mr. Goring Thomas's " Esmeralda,'* and Mackenzie's "Colomba," are a credit to Eng- land, and have already met with merited success on the Continent.
