of one or more light notes as in (34). Others were introduced 
than the one shewn, but they were so lightly uttered, and varied 
so much in position, that they baffled me in any attempt to fix 
them. The jangle (35) lasted nearly two seconds. (36) took 
barely a second; the jangle was enclosed between expletives. One 
jangle opened with a barbaric twang. These jangles sounded as 
though the bird merely set free the mechanism, and then the bells 
producing the notes swung freely in no determined order, and

repeated. At times the notes were clear, and at times confused

The jangles above are a few of the more definite of those re¬ 
corded; the others, and there were many, sweet bells jangled, 
but never out of tune and harsh, were yet too complicated and 
quickly tumbled for me to do more than admire. 
There is an allied series, bell-cascades or runnels, where the 
bird seems to exercise more control over the notes, every runnel

light note, and followed by a sustained diminishing note, the 
whole occupying a second and a half. The trebling of the notes of
