Fourth day. Ascent of Monadnock Mt. [Mount Monadnock]
Drive to Groton. 
1875.
June 19 [June 19, 1875] Clear with frequent intervals of clouds,
and much haze. Started immediately after
breakfast & drove to the Mountain house
half way up Monadnock, where we left
our team and ascended the rest of the 
way on foot. The path was very steep
and the walking difficult. Reaching 
the summit we found the view almost
as badly obscured by haze as that from
Wachusett [Mount Wachusett] on the 17th inst. [June 17, 1875] so we soon
satisfied our curiosity and reached the 
Central house by 1.30 P.M. Monadnock 
is every inch a mountain, 3800 ft.
about the sea, and with a fine picturesque
outline. All arborescent vegetation ceases 
some 300 ft. below the summit which 
is rocky and windswept with a few 
grasses ferns etc. growing in the hollows. 
Above or at the edge of the timber line 
were heard Junco hyemalis, Pipilo erythrop. [Pipilo erythropthalmus],
Geothlypis trichas & Helmin. ruficapilla [Helminthophila ruficapilla]. Lower
down Dend. virens [Dendroica virens], Parus atricapillus,
Turdus migratorius, & Spizella socialis.
Below the Mountain house Dendroica
maculosa, Pennsylvania [Dendroica pensylvanica] et Blackburniae [Dendroica blackburniae]
(one of each, the latter shot) and in the
pasture land near the base Pooecetes
gramineus. In a little hollow among 
the rocks above the sharply defined timber
line were a few stunted shrub oaks and 
here were singing Hel. ruficapilla [Helminthophila ruficapilla] Pipilo
ery. [Pipilo erythrophthalmus] and G. Trichas [Geothlypis trichas]. The latter bird seemed
abundant all over the mountain and
their songs were I thought very different from
those of our lowland birds, ending as they
