of the gorge and had burned off long-familiar patches of Aspidium 
fragrans (L.) Sw. and Woodsia alpina (Bolton) S. F. Gray. To 
complete the shock to a former lover of the Falls, a dam had been 
constructed and a large power-plant occupied a conspicuous place in 
the Basin. But neither the forest-fire nor the dam and the power- 
plant could completely obliterate the rush of the swirling water nor 
the grandeur of the place, and, intent upon visiting the long-known 
plants of the region and upon searching new spots, we were soon 
oblivious to the destruction which had been wrought. The rock- 
crevices, as always, were full of Anemone multifida Poir., Viola labra- 
dorica Schrank, Solidago racemosa Greene and S. hispida Muhl.; 
and, as on former trips, in the wet springy hollows were found Ryncho- 
spora capillacea Torr., Primula mistassinica Michx., Lobelia Kalmit 
L. (with a beautiful albino form) and Erigeron hyssopifolius Michx. 
A “game leg” unfortunately forced Dr. Hay to abandon the lower 
half of the gorge and to return to smoother travel on the highroad, and 
we were forced to make our way without him over the ledges and 
through tangles to Four Falls at the mouth of the Limestone River, 
as it enters the Aroostook. Below the Basin the forested bank was 
uninjured and on the cool moist rocks Anemone multifida Poir., Arabis 
hirsuta (L.) Scop., Amelanchier spicata (Lam.) C. Koch, Astragalus 
eucosmus Robinson and Erigeron hyssopifolius Michx. were in much 
finer development than farther up-stream. At one point halfway 
to Four Falls we were attracted to a springv spot under the bank 
unusually bright with Habenaria dilatata. (Pursh) Gray, Parnassia 
caroliniana Michx. and Lobelia Kalmii L.; and here we were delighted 
io find Scirpus pauciflorus Lightf. which is abundant about wet 
marly shores along the Limestone Hiver in Maine but has not, 
apparently, been reported from New Brunswick, and Arnica mollis 
Hook., var. petiolaris Fernald at the first station east of Moxie Falls 
in Somerset County, Maine. Above the mouth of the Limestone 
River the gravelly flat is covered with an almost impenetrable tangle of 
Crataegus, with Vitis vulpina L. at its northeastern limit; and as we 
came up the bank along the Limestone, where Carex eburnea Boott 
(as yet unknown in Maine whose borders are close by) abounds, we 
found a fine clump of Solidago altissima L., already known from Fort 
Fairfield, though nowhere else in Maine or New Brunswick. We 
reached Aroostook Junction in season to wave a farewell to Dr. Hay 
who was obliged to start back to St. John on the afternoon train, and
