 land. On too many farms something green, and plenty of it, 

 appears to be the supreme object of attainment. Whether the 

 crop is made into hay, or beasts and sheep are turned out to

 animals are expected to thrive on the herbage. 



Every arable farmer knows that unless land is kept clear 

 of couch, black grass, thistles, &c, the crops of corn must 

 suffer ; but it does not appear to be equally evident to the 

 grazier that certain plants, however useful they may be else-

 to be directly injurious or actually poisonous to sheep, and 

 especially to milch cows. The erroneous impression that it is 

 difficult or impossible to eliminate these worthless or injurious 

 plants from grass land has deterred many farmers from 

 attempting the task, or, at all events, there has not been the
