Concord April 22, 1904.
  Brilliantly clear with light S.E. [southeast] wind. Ground
frozen at sunrise but air delightfully warm through day.
  Working all day in Pine Park with Hansen
& Pat. We set out a lot of small pitch pines to
replace those ruined by the mice which have also barked 
a few white pines. Walked at evening over Pine Ridge.
A Bubo hooting there. Went to farm for an hour in A.M.
Arrivals 2 [in a flock] Yellow rumps on Ball's Hill this morning.
1 Bittern pumping twice on the Great Meadow at evening.
Yellow Redpolls & Hermit Thrushes still numerous. 5
Fox Sparrows at Ball's Hill & 3 at farm.
