Juncua mbeaudahu and a peculiarly brittle and fastigiate-branched 

 extreme of Barionia panictdata, a variety heretofore known only 

 from Sable Island. Thelypteris simulata was abundant in spruce and 

 alder thickets and the handsome Aster nemora&w, var. major Peck 1 

 was beginning to bloom. The Lycopus uniflorus of these thickets 

 had an unfamiliar appearance and upon returning to Cambridge I 

 find it to be var. ovatus Fernald & St. John*, recently described from 

 Sable Island and Canso. 



The blackish-fruited Chokeberry, Pyrtu arbtUifolia, var. airo- 

 purpurea, is everywhere abundant in western Nova Scotia and had 

 for some time shown its characteristic color, but here many of the 

 smaller-leaved shrubs had the small berries just reddening and were 

 obviously typical /\ arlmtifolia, not positively known nearer than 

 Cape Cod and Plymouth County, Massachusetts. The inundated 

 sandy margin of the lake was carpeted with unusually fine StAvlaria 

 aquatica and a stranger happening along would have been amazed 

 to see five men standing in water above their knees, bent over and 

 intently watching the bottom and every few seconds making a plunge 

 to the shoulder with the right arm. After lunch Bissell and Dr. 

 and Mrs. Craves started toward Tusket to catch the train; but Long, 

 Linder and 1, having determined to make a circuit, of the lake, kept 

 on to the north. Everywhere the thicket was bordered by Rvbus 

 tardatus of Cape Cod and of York County, Maine, one of the most 

 characteristic blackberries of these lake margins; and the ledgy shores 

 had colonies of the Panicum so characteristic of the coastal region of 

 southern New England, which has been referred to P. virgatum, var. 

 cvbense. 



Approaching sunset warned us before we had got half the length 

 of the west shore that our plan to encircle the lake was too ambitious. 

 The fog was still with us and during the eight-mile road-walk into 

 Yarmouth we amused ourselves vainly attempting to make out the 

 outlines of more than two of the roadside telephone poles at a time, 

 — an index to the extreme density of the atmosphere. It was some 

 days after this, when the uninterrupted fog was in its fourth week,
