The capital of Uruguay contains the usual educational and religious, charitable and scientific, public organizations, with appropriate edifices for the same. It should certainly be considered a reading community, having more daily newspapers than London, and double as many as the city of New York; also supporting a large number of weekly newspapers and monthly magazines. As to books, so far as a casual observer may speak, they are few and far between in family circles. The men read the newspapers, and the women fill up their leisure time with music and gossip. There is a national university in Montevideo, where over six hundred pupils are regularly taught at the present time, and there are forty-eight professors attached to this admirably organized institution. We heard it highly spoken of by those who should be good judges in educational matters. The custom house, with which the stranger always makes an early acquaintance after arriving in port, is a large and costly structure, three stories in height. The opera house is worthy of particular mention, being a spacious building of the Doric order, capable of seating three thousand persons, and when it is filled at night, the interior presents a grand array of elegant costumes and female beauty, the ladies of this city being noted for their personal charms. This is a circumstance not mentioned casually as a mere compliment, but simply as a fact. The opera house covers an entire square, and has two large wings attached to the main building, one of which is devoted to business purposes, and the other contains the National Museum. There is here the nucleus of a most valuable collection, to which constant additions are being made, both by the state and through personal liberality and interest. We are sorry to say in this connection that the bull-fight, as a public exhibition, above all other styles of amusement, is the favorite one with the rank and file of the populace, which is quite sufficiently Spanish to control the matter and insure its permanency. The bull-ring, wherein these brutal and terribly demoralizing exhibitions take place on each Sabbath afternoon during the season, is situated about a league from the city proper.
