Pushing on through India to the British Colonies again, whence we started, we descend to the ground floor, and resume our survey of Sweden, Norway, Italy, and Rome, and turn into the Music Hall, which is on the south side of the entrance and Statuary Hall. Here we find the organ builders at work on the grand organ, blowing up one pipe after another, and producing such volumes of inharmonious sounds that we are glad to leave them to the full and hearty enjoyment of their pipes, chords, discords, and bellows-blowing. The walls of the Music Hall are nearly covered with cartoons and paintings of a high-class, some of them so high that we require an opera-glass to bring them within the range of our visual organs. We next enter the Sculpture Hall with a view of examining the statues and describing them carefully. But they are so numerous that we can only find space to call attention to the most striking. There are over three hundred pieces of sculpture from various countries, comprising colossal and life-size figures, groups, busts, statuettes, and alto-relievos in marble and bronze. The most attractive of the marble statues are "Michael Angelo, when a child, sculpturing the head of a Faun" (his first work), by Emilio Zocchi, of Florence. The earnestness of purpose and devotion to his task are wonderfully expressed in the countenance of the boy-sculptor. Plying the hammer and chisel actively and vigorously, every part of the figure betokens a thorough abandonment to his occupation. A very remarkable work by a lady sculptor--Miss Harriett Hosmer--entitled "The Sleeping Faun," is the very opposite to the other, in its complete abandonment to repose. This fine statue has been purchased by Mr. Guiness, and we were told he had given a munificent sum for it. Another piece of exquisite beauty and daring skill in marble working is "The Swinging Girl," by Pietro Magni, of Milan, the sculptor of "The Reading Girl," which attracted so much attention in the International Exhibition of 1862. The figure of the girl swinging is beautifully modelled, and entirely free from contact with the base; and is supported only by the swing attached to the branch of a tree, and the hand of a boy giving action to the subject. "Ophelia," by W. C. Marshall, is perhaps the most poetic conception of the loveliest and most mournful of Shakespeare's creations that has ever been sculptured. It is almost impossible to look at this touching representation of Ophelia in her madness without exclaiming, in a modified quotation of her own description of Hamlet-- "O, what a gentle mind is here o'erthrown."
