1910) Fernald and Wiegand,— Botanizing in Maine 111 
surface, stood acres of clumps of Scirpus fluviatilis (Torr.) Gray, a 
stately bulrush once reported as growing at Perry, Maine, but hereto- 
fore unverified from east of the lower Merrimac. About Passama- 
quoddy Bay we had grown callous to the attractions of Potentilla 
palustris (L.) Scop., var. villosa (Pers.) Lehm., but at twilight a beau- 
tiful silvery variation of the species was found on the Nerepis marshes 
and a single specimen taken in the dim light “for locality," under the 
impression that it was var. villosa. Later, however, too late to return 
for more, it proved to be var. subsericea Becker (see below) a very 
beautiful plant, worthy a place among cultivated semi-aquatics. 
A portion of another day was devoted to an interesting meeting of 
the Natural History Society of New Brunswick, held at the picturesque 
summer-cottage of Senator Ellis, in full view of the gorge and falls at 
the mouth of the St. John River, where are found Saxifraga Aizoon 
Jacq. and some other boreal calciphile plants. Along the river near 
Senator Ellis's cottage we saw Juncus alpinus Vill. which is common 
farther north; and while waiting for our return train we found the 
yard of the Canadian Pacific Railway at Fairville a veritable garden 
of ballast weeds, chiefly brought from the West, — Glia linearis (Nutt. ) 
Gray, Ambrosia trifida L., var. integrifolia (Muhl.) T. & G., Artemisia 
ludoviciana Nutt., A. frigida Willd., ete. 
On Monday morning, August 9, accompanied by Dr. Hay, we started 
for Fort Fairfield near the mouth of the Aroostook River, reaching 
there in time for a short walk along the river before supper. Fort 
Fairfield for nearly a dozen seasons (at intervals since the early 60's) 
has furnished all the interesting material visiting botanists have been 
able to put up; and, although it was a familiar region to one of the 
party, he found at the end of the third day that, in spite of good reso- 
lutions to the contrary, his trunk was full of specimens and a large 
package had to be shipped to Pembroke by express. After the sterile 
coastal region of eastern Maine it was indeed a delight to find our- 
selves in a rich limestone country where we struggled through tangles 
of Salix glaucophylla Bebb and S. pellita Anders., with Onoclea 
Struthiopteris (L.) Hoffm. and Bromus altissimus Pursh brushing 
our faces, and Lilium canadense L., with ten to twenty flowers, and 
Cirsium muticum Michx. towering above our heads. Our limited 
time and two days of drenching rain forced us to restrict our botanizing 
to the shores of the Aroostook River, so, equipped with rubber coats, 
slouch hats and storm rubbers, we went first to the gravelly shore
