1902.
May 1
  Partly cloudy with light showers in forenoon.
  Took the 5.01 P.M. train for Concord. As we 
passed the E. Lexington station I was surprised to 
see that a considerable part (more than half, seemingly)
of the upper reservoir was bare mud flats. The pumping 
station there was discontinued more than a year ago
but the water was kept at its normal level through
last summer and autumn and I think the Greebes bred
there in their usual numbers. They will probably have
to go elsewhere now that the water has been drawn off
although there are still some broad ditches full to the
brim and apparently an acre or two of pond on the
northern side of the reservoir.

  The vegetation is remarkably far advanced. At
Cambridge pear trees are in bloom, cherry trees shedding
their petals, and horse chestnuts in nearly full leaf.
Here the shad bushes have unfolded a few blossoms,
the willows and poplars as well as the white maples
are covered with leaves - perhaps one quarter grown &
even the leaves of the oaks burst their buds
and tinge the trees with pink and salmon.
Vegetation
  Barn Swallows, Chimney Swifts, Brown Thrashers, Black
& White Creepers are all here. I heard two Carolina Rails 
this evening out in the Great Meadows which are still
partially covered with water.
  Hylas, Leopard Frogs and Pickerel Frogs are making
a tremendous din as I write. I heard Toads in Cambridge to-day.
