THURSDAY.—They keep two teams of singers in stock for the chief roles, and one of these is composed of the most renowned artists in the world, with Materna and Alvary in the lead. I suppose a double team is necessary; doubtless a single team would die of exhaustion in a week, for all the plays last from four in the afternoon till ten at night. Nearly all the labor falls upon the half-dozen head singers, and apparently they are required to furnish all the noise they can for the money. If they feel a soft, whispery, mysterious feeling they are required to open out and let the public know it. Operas are given only on Sundays, Mondays, Wednesdays, and Thursdays, with three days of ostensible rest per week, and two teams to do the four operas; but the ostensible rest is devoted largely to rehearsing. It is said that the off days are devoted to rehearsing from some time in the morning till ten at night. Are there two orchestras also? It is quite likely, since there are one hundred and ten names in the orchestra list. Yesterday the opera was “Tristan and Isolde.” I have seen all sorts of audiences—at theaters, operas, concerts, lectures, sermons, funerals—but none which was twin to the Wagner audience of Bayreuth for fixed and reverential attention. Absolute attention and petrified retention to the end of an act of the attitude assumed at the beginning of it. You detect no movement in the solid mass of heads and shoulders. You seem to sit with the dead in the gloom of a tomb. You know that they are being stirred to their profoundest depths; that there are times when they want to rise and wave handkerchiefs and shout their approbation, and times when tears are running down their faces, and it would be a relief to free their pent emotions in sobs or screams; yet you hear not one utterance till the curtain swings together and the closing strains have slowly faded out and died; then the dead rise with one impulse and shake the building with their applause. Every seat is full in the first act; there is not a vacant one in the last. If a man would be conspicuous, let him come here and retire from the house in the midst of an act. It would make him celebrated.
