Thus it is that by cutting off the plants 

 continually for an entire season as soon as they 

 appear above ground they will die out and not ap- 

 pear again on that area unless, of course, the seeds 

 are again introduced. 



Most weeds are provided with greater facilities 

 for reproduction and distribution than cultivated 

 plants. Most weeds also have some special means

Many of them, such as cockleburs (Xanthinm), 

 sandburs (Cenchrus), burdock (Arctium) and 

 stick- tights (Bidens), have burrs surrounding each 

 seed which are made up usually of many hooks or 

 spines. These seeds attach themselves to the 

 clothing of persons and to the various domestic 

 animals, and are thus transferred from one locality 

 to another. 



Many of the weed seeds such as the thistles, 

 wild lettuce, dandelions, etc., are provided with a

Some seeds are borne in fruits which are 

 relished by birds and animals. The seeds in this
