ripening of the seed is a better preventative, and if ]iersisted 

 in for a few years the carrot will be eradicated. 



Sorrel {Bumex AcetoseUn) is often ])roinineiit in j\o\v 

 seeded mowings, bnt connnonly disap])ears after one or two 

 years. Its presence is an indication that the soil would be 

 benefited by a liberal aj^plieation of lime. 



It seems to be impossible to procure grass and clover seeds 

 entirely free from dock (Rumex crispus). The plants should 

 be pulled after the stems become tough, but before the seed 

 matures, which is best done after a rain, when the soil is soft. 

 Hand-pulling is the method generally preferred, but there is 

 no doubt that cutting the roots a couple of inches below the 

 ground will destroy almost all plants. 



Buttercups, common plantain, dandelions and ragged robin 

 frequently become quite numerous in mowings, but are not 

 hard to keep in subjection. Liberal use of fertilizers will 

 so strengthen the grasses and clovers that these weeds cannot 

 become very prominent. 



Horsetail (Equisetum arvense) sometimes becomes very 

 abundant in mowings, usually in soils that are rather sandy 

 in texture, but have at the same time a fair capacity for hold- 

 ing water. Mowings that are badly infested should be broken 

 uj) and reseeded, with thorough cultivation before seeding, 

 as its presence in mowings is sometimes a source of danger 

 to horses fed with the hay, it exerting a distinctly injurious 

 effect when consumed in quantity, and sometimes causing 

 death.
