In Chicago their success was none the less flattering. In this, styled by many the "Queen City of the West," the remarkable musical powers of these young ladies created intense excitement, especially among people of the highest musical culture. The extraordinarily high range of the voice of Anna Hyers quite astonished every one who heard her, and evoked the warmest praise of the critics. For the purpose of assuring those who had not heard her sing, or who, although present, failed to exactly locate in the scale her greatest altitude, as well as to more pointedly mark this rare achievement in vocalism, a number of the best musicians of Chicago published a card in "The Tribune," in which they declared that "Miss Anna Hyers sang at the concert last night the second G above the staff,--a note touched by no other singer since Jenny Lind." Still proceeding towards the East, they next appeared in Cleveland, O., where their delightful vocal powers were thus alluded to by "The Daily Leader:"-- "On Saturday evening last, we had the pleasure of listening to the Hyers sisters, who have, since their appearance in public, been the recipients of the most flattering testimonials; and are warranted in saying, not without the best claim to them, the exhibition they gave of their ability was most satisfactory. The soprano (Miss Anna) has an exceptionally pure, sweet voice, with ample power for all the demands of the concert-room. Her execution was admirable. The contralto (Miss Emma) possesses a voice of remarkable quality; and we do not hesitate to say that a richer or more evenly-conditioned contralto voice is rarely heard. Her execution was all that could be desired." Encouraged by the marked success which had thus far crowned their efforts, their father, with whom and under whose direction the Misses Hyers had travelled since leaving California, now determined to enlarge his troupe. This he did by engaging the services of Mr. Wallace King of Camden, N.J., a gifted and accomplished tenor-singer; Mr. John Luca, widely and favorably known from his connection formerly with the celebrated "Luca family," and who sang baritone; while as accompanist he engaged the fine pianist, Mr. A.C. Taylor of New York. An intelligent idea of the composition of Mr. Hyers's troupe can be formed by a perusal of the following, which was the preface given to the programme of his concerts:-- [Illustration: THE GREATEST MUSICAL PHENOMENA OF THE AGE!
