places and amongst old ruLbish. The Thorn-apple (Datura sira- 
moiiituaj, a native of Europe and Asia, extending as for north as 
Sweden, and scantily met with in England — where it is an escape 
from gardens — occupying similar situations to the Henbane, has 
been introduced under a new name, as the “ Jimson Weed ; ” and 
this name seems to indicate that it was first noticed as a nuisance 
in the neighbourhood of Jamestown, in Virginia. The common 
Hemp ( Cannabis sativaj, .so valuable for its fibre, a native of the 
(’aucasu.s, and of the mountains of Northern India, and well 
known in Central Europe as a cultivated plant, which was doubtless 
introduced for economic purposes, has run completely wdld, and may 
now be found in waste places near dwellings in Montreal and 
Jjoston, and to the west of Ohio, and probably further still. The 
Grape-hyacinth and Star of Eethlehem, both common to gardens 
in Tmgland, may occasionally be found in the vicinity of Montreal. 
Ihe Corn-cockle (Lychnis yithayo), so mischievous in English 
llarley-ficlds, is tolerably common in similar places ; but as in Europe, 
has not succeeded in establishing itself beyond cultivated fields. 
Ihe common lied Clover f'rrifuUnm i>ratcnsc)\s not common; it 
seems as it it coidd not stand the cold and severe wintei's. Its 
near relative, however, the White Clover (Trifolium repens J, was 
introduced in early days, and called by the Indians “ The White- 
man’s- foot.” Longfellow, in the story of “ Hiawatha,” .says : — 
“ Wheresoe’er they tread, beneath them 
“ Springs a tiower unknown among us— 
“ Springs tlie ‘ White-man’s-fooC in blossom.” 
This is much more hardy than its congener, and is seldom killed, 
excepting in severest frosts. It overruns fields, waj-sides, and com- 
mons ; holding its own amongst the aborigines, strangling thorn 
by its tangled perennial roots. Early in the spring it makes such 
headway that larger and coarser plants are compelled to succumb ; 
its floAvei's afford the Honey-bee so rich a harvest, that its seeds are 
.surely fertilized ; and this double reproduction, by roots and by 
seed.s, gives it an advantage in the struggle for existence, so that it 
luvs rapidly spread over the country ; and many an American 
common is white with Clover, as an English lawn is white with
