“They returned to Germany at the end of August, to Nuremberg, which he notes as the ‘city of exquisite glimpses,’ and to Heidelberg, where they had their old apartment of thirteen years before, Room 40 at the Schloss Hotel, with its wonderful prospect of wood and hill, and the haze-haunted valley of the Rhine. They remained less than a week in that beautiful place, and then were off for Switzerland, Lucerne, Brienz, Interlaken, finally resting at the Hotel Beau Rivage, Ouchy, Lausanne, on beautiful Lake Leman” [MTB 923]. (Editorial emphasis.)
Of the trip from Bayreuth to Marienbad, Schornhorst (pg 7) writes: "The family left Bayreuth on August 11 and railed some sixty miles east to Marienbad, in Bohemia, where they spent the remained of the month. Sam was so enchanted by the landscape along the route; he had "never made so picturesque a journey before," ... " and there cannot be another trip of the like in the world that can furnish so much variety and of so charming and interesting sort."
The Wagner Opera festival opened in Bayreuth [Brooklyn Eagle, July 19, 1891 p.7]. This paper reported in a dispatch from London, “Bayreuth is overflowing with visitors, fully 50 per cent of them being Americans.” The Clemens party would arrive there on July 31 [July 10 to Hall]. The festival was held each year in the town of Wagner’s birth. Performances were given in a theater designed by Wagner in 1872, the Festspielhaus, with excellent acoustics.
