Lancaster, Mass.
  Cloudy with strong W. wind and light rain in P.M.
  Off for the day with John E. Thayer and his
assistant Albert Harriman, taking the road to the Pansy Farm.
  We stopped first at the grove of planted white pines 
in front of the abandoned school house to look at a
Vireo's nest which John Thayer had found several days ago
and which he had taken to be a Red-eye's. It was about
ten feet from the ground at the extremity of a long,
densely  -  feathered pine branch which extended out over a
cart path just where the latter entered the grove from the 
public road. The nest was so perfectly concealed by the
mass of pine foliage which surrounded it that it could
be seen only from directly beneath. To our surprise it
proved to belong to a Solitary Vireo although as on the
occasion of Mr. Thayer's first visit a male Red-eye was
the only Vireo singing in the grove. The female Solitary, however,
was sitting on her three fresh eggs and as she did not
leave the nest until we pulled down the branch nearly
to a level with our heads as we stood up in the
wagon we in identified her beyond question. After we
had taken the nest in hand the male Solitary singing
in brown oak scrub on the other side of the wood.
   Later in the day I found a second Solitary Vireo's
nest in the old white pine forest beyond the Pansy Farm.
It was in the top of a spreading, numerously  -  branched
out rather thin  -  foliaged Viburnum lentago which grew
in a partial opening over which stretched the long, lateral 
branches of several layer pines. During our last visit (on June 3)
to these woods I had heard the male Solitary singing within
