LAWN BEAUTIFICATION 291 



with noxious weeds. From a small sample, the 

 quantity and kinds of weed seeds may be de- 

 termined. This is especially true of alfalfa, 

 clover, and lawn grass seeds. 



If the sample contains weed seeds, it had better 

 be rejected, for there are always weeds enough to 

 contend with without sowing more. 



Grains, clovers, and grass seeds are far more 

 apt to have foreign seeds mixed with them than 

 any other class of seeds as they are usually har- 

 vested by the wholesale, weeds and all, and it 

 is only by careful screening that the other seeds 

 can be removed. With seeds of hoed crops, such 

 a condition does not exist. 



It is impossible,, of course, to give here a com- 

 plete description of all the different kinds of 

 weed seeds, but pictures are given in the natural 

 color of some of the most common ones. By 

 comparing the seeds with these pictures it will 

 usually be possible to determine the kind of 

 weeds that are found in your locality. 



Of course, one must always expect to find a 

 few foreign seeds in a sample of grain, but re- 

 member that the weed seeds cost the same price 

 per bushel as the oats. 



In orchards, especially in California, the two 

 worst weeds are wild morning-glory and a new 

 species of perennial amaranthus.
