The wishes of his much-loved parents Mr. Bowers respected. For this reason he refused to join the famous "Frank Johnson's band" of Philadelphia, although strongly urged by its director; and all offers made to him to join other public organizations were declined for a long time. But his very rare powers as a tenor-vocalist were those which previous to the attainment of his majority had most attracted the attention and excited the admiration of many persons. Indeed, his voice was considered as something extraordinary in its power, mellowness, so to speak, and its sweetness. Thus endowed, it was not possible, in the nature of things, that he should remain only a singer in private; and so, at Sansom-street Hall, Philadelphia, in 1854, he was induced to appear with the "Black Swan" as her pupil. Although it was not at this concert that he made his first public "hit," as it is called, yet the press of Philadelphia spoke of his performances on that occasion in the most flattering terms, and called for a repetition of the concert. This was given, our subject meeting with still greater success. At this time, one of the critics, in commenting on the voice and style of singing of Mr. Bowers, called him the "colored Mario." Considering the almost if not quite peerless position then held in the musical world by the distinguished Italian tenor, Mario, this was a most strikingly favorable comparison. But our artist was so modest as to doubt that he merited such high praise. The press, however, generally persisted in styling him the "colored Mario," the "American Mario," &c.; and by these sobriquets he is most known to-day. Col. Wood, once the manager of the Cincinnati Museum, hearing of the remarkable singing qualities of Mr. Bowers, came to Philadelphia to hear him. He was so much pleased, that he entered into an engagement with him to make a concert tour of New-York State and the Canadas. This was in company with Miss Sarah Taylor Greenfield [Transcriber's Note: Elizabeth Taylor Greenfield], the famous songstress. The great vocal ability as well as the novelty formed by the complexions of this couple produced quite a sensation, and secured for them great success wherever they appeared. During this tour Col. Wood wished Mr. Bowers to appear under the title of the "_Indian_ Mario," and again under that of the "_African_ Mario." He withheld his consent to the use of either of these names, but adopted that of "Mareo." This he has since retained as his professional cognomen. Mr. Bowers was induced to engage in public performances more for the purpose of demonstrating by them the capacity of colored persons to take rank in music with the most highly cultured of the fairer race than for that of making a mere personal display of his highly-rated musical abilities, and for the attainment of the enjoyment which they would naturally be supposed to afford him. Writing to a friend, he thus speaks of the principle that governed him:--
