During the summer. of 1888 my attention was first called to its 
interesting flora, while staying at Berwick, Columbia county. The 
northern part of Berwick touches the southern boundary of Lu- 
zerne county. The county is cut almost in half by the Susque- 
hanna river, and contains seven marked geological formations. 
Within three of these, Chemung, Hamilton and Catskill forma- 
tion, and in territory chiefly within the limit of glacial action, it 
has been my privilege to collect, though to a very limited extent. 
The terminal moraine, as I have since ascertained, makes its 
appearance at Wapwallopen, about seven miles above Nescopeck, 
runs in a southwesterly direction across the river, which it follows 
nearly to Berwick, and thence passes into Columbia county. 
On the high bluff on the right bank of the river, and almost on 
the southern boundary line, is a quantity of Zissa rubra, and along 
the steeply-sloping sides, numerous patches of Sedum acre. Fol- 
lowing north, along the tracks of the Delaware, Lackawanna & 
Western Railroad, which runs parallel to the river and canal, many 
of our common plants are to be found. Here Solidago juncea 
blooms earlier than at any other place where I have seen it, mak- 
ing its appearance in July. 
Asclepias obtusifolia is not common, only two or three plants 
being observed, while a rare find in the shape of three plants of 
Spirea rubra, the only ones that I have ever seen growing wild, 
peeped out from the rank growth of grass and bushes. Afios 
tuberosa twined over the bushes, near neighbor to Phlox maculata 
and Lathyrus palustris. Down along the low margin of the canal 
a tangled mass of Myosotis laxa was guarded by the large and 
showy blue flag, /vs versicolor. In a little swampy place along 
the river, Veronica scutellata flourished, and in drier and more 
open places, Ranunculus acris and Gtnothera pumila. Growing in 
the sand on the river brink, was a little patch of Ranunculus reptans, 
which is completely submerged except at times of low water. 
In March, 1892, I spent two days at Berwick, and, while taking 
a walk along the railroad, observed a number of small pine trees 
growing on the side of the bank. They were full of cones, and 
close inspection satisfied me that they are Pinus echinata, although 
I do not have specimens to substantiate the determination. If it 
is really this pine, its appearance so far North is remarkable, at - 
least at such a distance from the coast. |
