DESCRIPTIVE MANUAL 307 



Wlien this weed grows over the whole field the only thing to do 

 is to put it through a course of rotation. "Where there is only a 

 stalk here and there it may be taken out with a 'spud,' which is 

 simply a two-inch chisel with a handle, by means of which the 

 farmer can cut out rapidly many of these weeds, but where it is 

 scattered over the field the only way is to put it through a course 

 of rotation."
