Cambridge - Portland, July 15 1904
  Clear & intensely hot.
Spent the morning in the Museum. With C. [Caroline] took
the 1.15 P.M. train for Portland, Maine arriving there
at 5.10. Just beyond Dover, N.H. [New Hampshire] we passed a long
succession of fields & meadows thickly spangled with
yellow lilies (L. canadense [Lilium canadense]) in bloom. In two places we
saw several acres of these lilies growing as closely
together as one ever sees golden rod.
  Spent the night at the Lafayette Hotel where Dr. &
Mrs Gehring joined us. C. [Caroline] & I had each a long talk
with our good Doctor.
