Upon the death of her mistress, in consequence of the contested will, she found herself thrown upon her own resources for a maintenance. Remembering some friends in the western part of New York, she resolved to visit them; while crossing Lake Seneca, en route to Buffalo, there came sweetly stealing upon the senses of the passengers of the steamer--her rich, full, round, clear voice, unmarred by any flaw. The lady passengers, especially the noble Mrs. Gen. P., feeling that the power and sweetness of her voice deserved attention, urged her to sing again, and were not satisfied until five or six more songs were given to them. Before reaching their destined port she had made many friends. The philanthropic Mrs. Gen. P., became her friend and patroness. She at once invited Elizabeth to her splendid mansion in Buffalo, and learning her simple story, promptly advised her to devote herself entirely to the science of music. During her visit a private party was given by this lady, to which all the élite of the city were invited. Elizabeth acquitted herself so admirably, that two days after a card of invitation came to her through the public press, signed by the prominent gentlemen of Buffalo, requesting her to give a series of concerts. She sang before the Buffalo Musical Association, and her performances were received with marks of approbation from the best musical talent in the city, that established her reputation as a songstress. Give the "Black Swan," said they, the cultivation and experience of the fair Swede, or Md'lle Parodi, and she will rank favourably with those popular singers, who have carried the nation into captivity by their rare musical abilities. Her voice has a full round sound, and is of immense compass and depth. She strikes every note in a clear and well defined manner, and reaches the highest capacity of the human voice with wonderful ease, and apparently an entire want of exertion. Beginning with G in the _bass clef_ she runs up the scale to E in the _treble clef_, and gives each note its full power and tone. She commences at the highest note and runs down the scale with the same ease that she strikes any other lower note. The fact that she accomplishes this with no apparent exertion is surprising, and fixes at once the marvellous strength of her vocal organs. Her voice is wholly natural, and, as might be expected, lacks the training and exquisite cultivation that belongs to the skilful Italian singer. But the _voice_ is there; and as a famous mæstro once said, "It takes a hundred things to make a complete singer, of which a good voice is ninety-nine." If this be so, Miss Greenfield is on the verge of excellence, and it remains for the public to decide whether she shall have the means to pursue her studies.
