Perennial Weeds.
This enumeration of noxious plants contains principally those which,
although they are very troublesome, are more easy of extirpation than
the last: for although the most of them are perennial, yet, as their
roots do not spread as those of the above list do, they are to be
effectually removed by taking up the plants by their roots. It should,
however, be always noticed, that it is to little account to endeavour to
clear any land of such incumbrances, if any waste places which are
separated only by a hedge are allowed to grow these things with
impunity; for the seeds will invariably find their way. The contrivance
of nature in their formation is a curious and pleasant subject for the
philosophical botanist; at the same time it is one of those curses which
was impelled on human labour.
