But the second physical feature is the great valley of the St. John river 
and its tributaries, whose flora is far more southerly in character than that 
above enumerated, although in its northern portions it has many striking bo- 
real forms. In the rich alluvial bottoms of the St. John and its tributaries I 
ean seen Struthiopteris Germanica six and seven feet high. Along the Tobique 
tiver I saw Osmunda regalis growing to the height and profusion to which alders 
gtow on the borders of other streams. I have before me a tuft of Elymus Can- 
adensis nine feet in height, collected at Eel river, one hundred miles from the 
mouth of the St. John. In the rich intervals there are Sanguinaria , 
m Canadensis, Caulophyllum thalictroides, Adiantum pedatum, and others whose 
growth would be impossible were it not that the cold fogs of southern New 
Brunswick have been dissipated by the sunshine which reigns here day after 
day, and that the rocky coasts have given place to alluvial meadow and green 
field, One other feature of this St. John river valley may be referred to. Ris- 
ing from the famous Aroostook region of Maine, it bears upon its waters the 
seeds of many plants, which are peculiar to this river so far as American bot- 
a #8 concerned. Among these may be mentioned Oxytropis campestris, 
= nus, Hedysarum boreale, Tanacetum Huronense and others.—Gro. U. Hays.
