Upon the whole we must in justice say, that Mr. Dwyer, so far as we have seen him go, has shown uncommon talents for the stage--that he is an acquisition to the American boards, such as we had not dared to hope for, and that we trust next season will bring him back, and exhibit him in a range of characters more varied and extensive, and better calculated to call forth the great natural powers of which he seems to be amply possessed. * * * * * _Grand Musical Performances._ In no country in the world is the practice of music more universally extended and at the same time the science so little understood as in America. Almost every house included between the Delaware and Schuylkill has its piano or harpsichord, its violin, its flute, or its clarinet. Almost every young lady and gentleman from the children of the Judge, the banker, and the general, down to those of the constable, the huckster, and the drummer, can make a noise upon some instrument or other, and charm their friends, or split the ears of their neighbours, with something which courtesy calls music. Europeans, as they walk our streets, are often surprised with the flute rudely warbling "Hail Columbia," from an oyster cellar, or the _piano forte_ thumped to a female voice screaming "O Lady Fair!" from behind a heap of cheese, a basket of eggs, a flour barrel, or a puncheon of apple whiskey; and on these grounds we take it for granted that we are a very musical people. When Boswell asked Dr. Johnson if he did not think there was a great deal of learning in Scotland, "Learning," replied the philosopher, "is in Scotland as food in a town besieged; every one has a mouthfull, but no one a belly-full." The same may be said of music in America. The summit of attainment in that delightful science seldom reaching higher than the accompanying of a song so as to set off a tolerable voice, or aid a weak one, and the attracting a circle of beaus round a young lady, while she exhibits the nimbleness of her fingers in the execution of a darling waltz, or touches the hearts of the fond youths with a plaintive melody accompanied with false notes. Thus far, or but little further, does music extend, save in a few scattered instances. Like a plover-call, it is used to allure the fluttering tribe into the meshes; but when it has done its office in that kind, is laid aside for ever. POPE SEXTUS QUINTUS, when he was a cardinal, hung up a net in his room, to demonstrate his humility, his father having been a fisherman; but as soon as he was made pope, he pulled it down again, shrewdly saying, "I have caught the fish." Miss Hannah More remarks that few ladies attend to music after marriage, however skilful they may have been before it. Indeed nothing is more common than to hear a lady acknowledge it. "Mrs. Racket will you do us the favour," &c. says a dapper young gentleman offering his hand to lead a lady to the piano. "Do excuse me, sir, I beg
