that he could interject it between the tue notes and, 
moreover, it seemed to come from another direction, but 
after repeated observations I became satisfied that it

but the sound is much louder than the tue and the intervals 
between the notes,although short,are well marked. Some¬ 
times the bird began slowly and gradually increased the 
rapidity of its utterance, at others the intervals were

ringing, although similar in general quality to that of 
the tue call, is less loud and is more evidently and 
directly connected with the note which it accompanies. In
