Concord, May 11 1904.
  Clear most of day with light W. to S.W. [west to southwest] wind.
Very warm in the afternoon.
  Only arrival noted was a Red-eyed Vireo in
feeble song.
  Spent day working in the flower garden
with Pat & Howard. At evening strolled to
Ritchie place & the Berry Pasture. When we
opened the Ritchie barn this morning a pair of
Barn Swallows entered & at once settled in an old
nest. They went to roost in this nest at evening.
