  For several seasons past whenever I have been staying
at Ball's Hill I have heard at morning and evening,
coming from the open fields and meadows of the West
Bedford side of the river what I have taken to be 
Guinea Hens calling. On several occasions I have thought
that the sound was not quite like that made by Guinea
Hens but as it usually came from the direction of
Mr. Grath's poultry yard and as he keeps (or used to keep)
a few of these birds I did not give the matter any
particular attention. For the past three or four evenings this
calling has been frequent and insistent for half an hour or more
after sunset and again about sunrise or before. Last
evening I heard it to uncommonly good advantage and
studied it attentively. I soon satisfied myself that it
was not the call of a Guinea Hen. The voice is less
harsh, the notes given more slowly. They have a peculiar
Evening call of Ring Neck Pheasant (?)
