No. 4.] MANAGEMENT OF MOWINGS. 381 



cup and plantain. Farmers may send samples of seeds to 

 the Experiment Station for examination ; but it would be a 

 relatively simple matter for any farmer to collect a few seeds 

 of these commoner and more troublesome weeds, and keep 

 them for comparison with any foreign seeds which may be 

 found in grass or clover seeds purchased. In this way, by 

 the use of a magnitying glass of moderate power, the seeds 

 of any of the weeds mentioned can be identified. By the 

 exercise of care in the purchase of grass and clover seeds 

 much trouble and expense may be saved. 



The white daisy {^Ohrysanthemum LeucanfJiemwn) may be 

 })ractically eradicated from mowings without reseeding, by 

 persistent early cutting, usually from June 12 to 15, and 

 such enrichment of the soil as favors the growth of grasses. 

 This plant is a biennial, and it is only necessary to prevent 

 the ripening of seed. 



The yellow daisy (^Rudbeckla hirta) is not ordinarily 

 troublesome save on light soils. Pulling the plants soon 

 after they come into blossom will prove efficacious. 



The wild carrot (^Dancus Oarotu) is one of the most 

 troublesome Aveeds in mowings, and has been allowed in 

 many localities to ripen a tremendous amount of seed, so 

 that the soil is thoroughly infested with it, and replowing will 

 not be likely to prove eftective. Timely cutting to prevent 

 the ripening of the seed is a better preventative, and if per- 

 sisted in for a few years the carrot will be eradicated. 



Sorrel [liumex Acetosella) is often prominent in new seeded 

 mowings, l)ut commonly disappears after one or two 3'ears. 

 Its presence is an indication that the soil would be benefited 

 by a li))eral application of lime. 



It seems to be impossible to procure grass and clover seeds 

 entirel}^ free from dock (liumex cn'sjmft) . 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. 

 Iland-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 })lants. 



Buttercups, common plantain, dandelions and ragged robin 

 frequently become (|uite numerous in mowings, but are not
