After a while they visited England, where they sang before the Queen and others of the nobility, everywhere repeating the triumphs that had been theirs in this country. In fact, it was proved that their power as singers held sway wherever they sang; wherever was found a soul in unison with melodious sound, a heart capable of human emotion. It was not so much the words of their songs--these, it is true, were not without merit in a religious sense--as the strangely pathetic and delightful melody of their music, and the freshness and heartiness of the rendering, that gave them their greatest charm. This has since been most pointedly demonstrated in Holland and Switzerland, where these singers have drawn crowded and delighted audiences that neither speak nor understand a word of English: such is the beautiful, far-reaching power of this, in the truest sense, "music of the heart." I now present a few of the many tributes of admiration which their performances drew from cultured English people. Thus spoke Mr. Colin Brown, Ewing Lecturer on Music, Andersonian University, Glasgow:-- "As to the manner of their singing, it must be heard before it can be realized. Like the Swedish melodies of Jenny Lind, it gives a new musical idea. It has been well remarked, that in some respects it disarms criticism; in others it may be truly said that it almost defies it. It was beautifully described by a simple Highland girl: 'It filled my whole heart.' "Such singing (in which the artistic is lost in the natural) can only be the result of the most careful training. The richness and purity of tone both in melody and harmony, the contrast of light and shade, the varieties and grandeur in expression, and the exquisite refinement of the _piano_ as contrasted with the power of the _forte_, fill us with delight, and at the same time make us feel how strange it is that these unpretending singers should come over here to teach us what is the true refinement of music; make us feel its moral and religious power." Others spoke as follows:-- "I never so enjoyed music."--REV. C.H. SPURGEON. "They have beautiful voices."--_London Graphic._ "Their voices are clear, rich, and highly cultivated."--_London Daily News._ "This troupe sing with a pathos, a harmony, and an expression, which are quite touching."--_London Journal._ "There is something inexpressibly touching in their wonderfully sweet, round, bell voices."--REV. GEORGE MACDONALD. Mr. Gladstone, while prime-minister of England, honored them with a complimentary breakfast, and listened to their songs, as Newman Hall writes, "with rapt, enthusiastic attention, saying, 'Isn't it wonderful? I never heard any thing like it.'"
