THE VOICE.

wlio is himself not only an expert in bird’s song, but also 
a composer, and the inventor of some new instrument, 
upon which he can, with some degree of exactness, 
reproduce the flute-like tones and other peculiarities of 
the notes, as well as the different gradations in crescendo 
and diminuendo, together with the varied strength of the 
song in technically correct succession. And, after all, 
even such an imitation as this would be as much inferior 
to the original as the best vox humana organ-stop falls 
short of representing the human voice. It is only in the 
mouth of a singer that the human voice rises to a ringing 
soul-inspiring song; the bird’s heart must compose, and 
the bird’s mouth must sing the bird’s song, if it is to be 
what it is, in very truth,—a living and life-stirring 
reality.
