Plants are assisted to become weeds by producing many seeds, 

 by ripening with the crop so the seeds are harvested with it, liy 

 ripening before the crop and scattering seeds on the ground, by 

 producing seeds which are not easily separated by sieves, by pro- 

 ducing very small seeds which escape notice, by having a supply 

 of hairs that they may be carried by the wind, or some awns oi- 

 hooks to hold fast to animals, by remaining a long time in the 

 soil without losing their vitality. l)y producing long or thick roots 

 not easih' eradicated, by producing bulbs, or long root stocks, by 

 being oifensive to all kinds of stock so they ai-o allowed to grow 

 and muliiply. 



Clay soil is less likely to be troubled tluin loam or sand.

 and clovers in the Xortheru States are here enumerated, with
