here and its chief value consists in its arrangement and 
separation of the plants indigenous from the introduced 
weeds, thus giving what then appeared to be the plants 
which came with man or, as he called them, “Such plants as 
have sprung up since the English planted and kept cattle 
in New England.” ‘This, with the occasional observations 
by other writers, gives us a fair idea of what plants had 
established themselves here rather more than two hundred 
years ago. According to Professor Tuckerman, the next 
date by which the student may fix the introduction of 
foreign species is 1733, when the list of plants observed 
by Rev. Manasseh Cutler, of Ipswich, was published 
(Mem. Am. Acad. Vol. 1). Since that date observations 
are more frequent and the more recently introduced 
species can be traced quite accurately. Itis also quite 
- probable that plants which at one time were quite common 
weeds have disappeared altogether. Dr. Cutler mentions 
the Amarantus known by the common name of “ Prince’s 
Feather” or “ Love-lies-bleeding,” as “amongst rubbish,” 
but to the present writer’s knowledge it is never met with 
excepting in old-fashioned gardens. The Hyoscyamus 
niger and Artemisia Absinthium (Wormwood), spoken of 
by Dr. Cutler and other earlier writers as common in waste 
places, are now very rare or unknown. The last mention 
of Nicotina rustica is by Dr. Osgood in 1853, but it is 
doubtful if he observed it as late as that ; his observations 
were very probably made in previous years, and no one has 
since noticed it. The introduction of new manufactures 
is likely to bring with it plants which may be persistent 
enough in the region where they are introduced but un- 
known elsewhere. Such is the case at “ Tapleyville,” 
Danvers, where, in the vicinity of a carpet factory estab- 
lished forty years ago, are to be found several species of
