156 PERMANENT AND TEMPORARY PASTURES 



Water Pepper (Polygonum Hydropiper). — An evil- 

 smelling, pungent annual, which grows in ditches and water- 

 courses, and affects the milk of cows if eaten. It should be 

 rooted out and destroyed. 



Yellow Rocket (Barbarea vulgaris). — A yellow-flowered 

 cruciferous plant, which often grows in abundance by ditches 

 and streams, and in early spring throws up large tufts of 

 turnip-like leaves, which, notwithstanding a pungent, nauseous 

 flavour, are freely eaten by cattle, with the result that milk 

 and butter are tainted. Before stock are turned on to the 

 pastures in spring a labourer should be sent round with a hoe 

 to cut the tufts below the crown, and as the plant is of biennial 

 duration only, it can be easily destroyed. Seeding should not 

 be allowed. 



As a rule, the wise and safe course is to collect all injurious 

 plants after they are cut or uprooted, and burn them.
