Morning drive

May 10
Mass.
Cambridge - Belmont - Waltham. - A cloudless day, cool in
the early morning, very warm after 10 A.M. (the ther.
going above 70[degrees] later) with almost no breeze save
now and then a refreshing puff from the S.E. 
  Previous to the 8th, when I left Cambridge, then had
seen, for a week or more, almost no change in 
the vegetation and practically no arrivals of birds
the weather bring cook and at times really cold.
[deleted]water from 1/4 inch[/deleted] On the nights of the 5th and 6th 
ice found in pails to the thickness of 1/4  inch and
much damage was done to first buds and tender
plants. Several birds not usually seen here before the
end of the first week in May had arrived in April
but these were represented by only a few individuals
which did not increased as they days passed.
  On my return to Cambridge yesterday I found that
vegetation had made a marked advance. Denton
says that this was accomplished the night of the 
8th and forenoon of the 9th when the weather
became much warmer. He saw Orioles in Wellesley
on the morning of the 9th. On the evening of
that  day I noticed nothing new in my garden
but coming out this morning a little after
nine o'clock I became at once aware that
a very heavy flight of migrants had arrived,
probably last night. Standing on my front walk
I heard, within eight or ten minutes, chiefly in
the trees & shrubbery on the Hubbard place
opposite, the following birds singing: D. aistiva, two;
D. Coronata, one; [?] ruficapilla, one;
Vireo solitarius, one; V. gilvus, one; Carpodacus, one;
