Partly cloudy up to 10 A.M. After that clear
& very warm with high S.W. [southwest] wind.
Prolongued [prolonged] fine weather & almost incessant
strong wind have combined to dry up
surface moisture so that a spring drought

ones last week, in Concord & Acton.
Apple blossoms fading & shedding fast.
Lilacs, purple & white, in nearly full bloom.
