Cambridge, Mass.
1907
April 2
  After six successive days (March 25 - 26) of clear
and, for the season, warm weather. The seventh day (31st) 
was cloudy and cool but not frosty. The eighth day
(April 1st) was colder still with a north-east snow
storm which had covered the ground (although most of
the snow melted as it fell) to the depth of two or 
three inches by night.
  Early this morning the sun rose clear to shine
on a wintry landscape for the thermometer stood at
28 degrees and the earth was everywhere robed in
glistening white. When I reached the Museum I
found assembled in our garden such a horde of
migratory Sparrows as I have not seen there
there before for more than twenty-five years. It
was impossible to count them accurately but the
results of many attempted counts convinced Mr. Dean
and me that there were not less than 40
Fox Sparrows, 8 or 10 Juncos and 3 Song Sparrows.
They remained in the Garden all that day and
on the next day their number was not greatly
diminished. Whence came they? Not from the 
south I think for the night of the 1st was
not one to tempt birds of any kind to move
northward. At first I suspected they might have
been driven into town from the open country
but I learned later that on this same day they
were still more numerous at Ball's Hill, Concord,
and that upwards of 100 were seen (by Will. Stone)
in a vacant lot at the rear of the old Providence R.R.
station in Boston. (Stone says that most if not
all the birds he saw were Juncos & Song Sparrows).
