  The Partridge was sitting on the nest on the
W. side of Ball's Hill Swamp when Gilbert visited it
at 11 A.M. yesterday. To-day at 9.30 A.M. he
found the eggs hatched and the whole family gone.
This nest was found May 11th. when it contained its
full complement of 9 eggs. At that date they
looked fresh but the bird was sitting close. Her mate
is, I suppose, the male that has been drumming through
the spring on the stone wall at the E. end of Ball's Hill
(this station is about 200 yards from the nest on the
opposite side of the swamp.) We have heard him
only a few times since May 11th. usually just at
evening, the latest occasions being May 29th. & 31st.
Gilbert brought in all the egg shells from this nest.
They were not telescoped as is usually the case but
some of the smaller ends were inside the larger. I
shall preserve them carefully just as they were
found.
