zontal branches hng the ground so closely 

 that, when the field is gone over again with 

 the scythe, it is not at all easy to cut them 

 off ; as the same thing occurs with each cut- 

 ting, as long as the growing period contin- 

 ues, and as the weed is a very prolific seed 

 producer, and as its seed is also very tena- 

 cious of life, it follows that in places where 

 cultivation is impossible, this pest is not a 

 very easy one to deal with. 



Blueweed grows in various kinds of soil, 

 but its favorite feeding grounds are those 

 soils which contain much lime. It grows 

 vigorously in gravelly soils, even in those 

 which are suitable for use in road-making, 

 hence we frequently find this plant growing 

 right up to the travelled portions of the 

 roads. 



As in the case of all or nearly all bien- 

 nials blueweed is not very difficult to keep 

 out of the cultivated portions of the farm, 

 but it is a very different matter when we 

 come to deal with it in fence borders, in 

 permanent pastures, on road sides, and in 

 waste places generally. In all these places 

 blueweed soon finds a congenial home, from 

 which it cannot be easily dislodged.
