Concord. April 17, 1904.
  Brilliantly clear with fresh N.W. [northwest] wind.
Ground frozen hard at day break. Midday pleasantly 
warm with the snow wasting fast. It was nearly
all gone by night.
  Karl Ellison brought down a wonderful inlaid 
table at 9 a.m. It had over 3000 pieces of wood of
8 different kinds. He stayed until 11 when I
walked up the road & called on Everett Mason.
To Ball's Hill in P.M. Lots of birds there. 4 [in a flock]
Yellow Palm Warblers, a Pine Warbler, a Ruby crown. Kinglet [Ruby-crowned Kinglet]
(chattering), 8 [in a flock] Fox Sparrows etc. Two [male] Purple Martins
flying over the river near Birch Gate. Got back at sunset.
