 English plantain (Fig. 263) and many others. 



(4) Road-side and fence-row weeds are often the same kinds

 and others seem to prefer neglected places. 



Losses Due to Weeds. Weeds growing with our farm crops 

 tend to smother the main crop, rob it of its plant food or shade it

 where Canada thistle, Johnson grass, or quack grass has taken 

 possession, the crop is reduced to a minimum. 



Loss in Pasture. Some weeds when grown in pastures are

 thorns and prickles. The grass growing near them is avoided by 

 pasturing animals and much loss is thus experienced. Fibrous 

 weeds found in pastures are sometimes injurious to the animals 

 themselves. Cattle are sometimes killed by eating the wild woody
