It seems we are soon to be blessed with a whole Hock of Opera Houses, if the Ihtzzard is rightly “informed.” A few days ago it announced that one would soon be erected on the corner of Galena and Chicago streets. Friday it has Messrs. Barnes about to begin the erection of another over their agricultural warehouse. If these two buildings are erected,and Mr. Wilcox on makes the improvements contemplated in bis, and which he can, when the new building now in course of erection is completed, this town will be a bonanza for hall shows, and Opera House stock can be bought cheap.
