Among these forms are such trees and shrubs as the
pitch pine, the   oak, the black birch, the gray birch
and the sweet fern and such birds as the Brown Thrasher,
the Yellow Warbler, the Warbling Vireo, the Yellow-throated Vireo,
the Field Sparrow, the Towhee and the Baltimore Oriole.
Conversely there are birds not known to occur in early
summer to the southward of Grafton Notch which breed
very generously throughout the heavily forested region lying
just to the northward. Good examples of this latter class
are the Hudsonian Titmouse, the Tennessees, Bay-breasted
Cape May and Mourning Warblers, the Philadelphia Vireo, the
Canada Jay, the Yellow-bellied Flycatcher, the two species
of Three-toed Woodpeckers, and the Spruce Grouse.
  It will be understood of course that what I have just said 
is intended to apply only to the seasons when these birds
are actually breeding and to their distribution at
these seasons in the country traversed by and at no great 
elevations above, the road. At considerably higher elevations
several of the species breed among the White Mountains not
far from Bethel and even further southward.
  Besides the instances just given there are others less
definite and striking, yet almost equally significant and
interesting, of forms of plant and animal life which, although
found almost everywhere along this road, become either
more or less numerously represented after one has passed
through the notch, whether to the northward or the southward.
