BLACK-=THROATED GREEN WARBLER. 
sings the two next to the last are burred, the others are 
clear. Mr. John Burroughs writes the song by a series 
of lines thus: ___ V — which forn, so far as it 
will answer the purpose of identification, can not be im- 
proved upon. But I shall always hold the opinion that 
a representation of sound, not to speak of song—wild or 
cultivated,—by other than scientific music signs, is an ex- 
tremely dubious method of conveying ideas. For that

book to show the parallels of haphazard symbols and 
exact musical notations. The foregoing signs, there- 
fore are properly interpreted this way:

I have added the popular idea about the sentiment of a 
song; that will certainly help to emphasize the rhythm. 
If you whistle this song between the teeth, and burr the

necessary to add that the song must be whistled in the 
high register where it belongs in accordance with the

ing form, obtained on one of the foot-hills of the

connected with it will testify. The day was a brilliant

up in the north over the blue and jagged horizon line 
formed by Lafayette, the Notch, and Cannon Mountain; 
below, in the broad sunlit valley, the beautiful Pemige-
