The theatre was re-opened on the 16th January, 1825, under the management of Messrs. Rosquellas and others, after having been closed two months for the purpose of repairs and alterations. Great improvements have been made: the seats in the pit are covered with crimson velvet; the whole interior of the house has been cleaned and painted; the stage thrown more forward, and the orchestra enlarged. A new drop-scene is exhibited, with the arms of the country and other devices painted upon it; and, from being better lighted, the theatre has now a neat appearance. The operatic department constitutes the chief attraction of the theatre: in this they have Rosquellas, Vacani (the renowned _buffo_), the younger Vacani, Vera, the two Señoras Tanis, and Doña Angelina Tani, who sings as exquisitely as ever. Vacani, upon his re-appearance, after a short absence, was hailed with shouts of approbation, and bouquets of flowers thrown upon the stage. In the dance, we have Touissaint, his wife, and a corps de ballet, including some Portuguese comic dancers from Rio Janeiro. Regular ballets of action now take place, in lieu of the pas de deux, and pas seul, of one or two principal dancers. Under the old Spanish regime, the season of Lent was the most gloomy part of the year; it is now the gayest: we have operas and ballets two and three times a week, to delighted audiences; selections from _The Barber of Seville_, _Figaro_, _Henry IV._ &c. the orchestra led by Masoni, the skilful Masoni, whose talent draws forth raptures of applause. It is in contemplation to get up regular operas, instead of detached pieces: _Don Giovanni_ has been mentioned--Rosquellas to be the hero; he would both look and perform it admirably, at least to those who have not seen Ambrogetti. At the theatre door, on performance nights, several handsome carriages are now to be seen, with lighted lamps and well-dressed servants, belonging to English and other families. When I arrived, in 1820, scarcely one was in existence. Were a Spaniard to revisit this place, after an absence of a few years, he would feel surprised at the alteration; the rigid fasts of the church laid aside for innocent enjoyments, the hum of business greeting his ear, and European strangers every where meeting his eye. Old Spain's ancient dominion of Buenos Ayres is gone for ever: a few of the old school may yet cling to the mother country; but the grand mass of the people, especially the younger branches, are decidedly patriots. An amateur performance took place, on the 21st February, 1825, for the benefit of the widows and orphans of those who had fallen in the revolutionary wars. It was a full house, and profitable--the reverse of Silvester Daggerwood's. Orders are not admitted to the Buenos Ayres theatre. The play was _Virginius_; and the different parts were sustained by gentlemen of the city, in a style so creditable, as to put to the blush the regular actors.
