LARGE CRAB-GRASS, SMALL 



CRAB-GRASS, AND PURPLE 



FINGER-GRASS 



The two Crab-grasses, large 

 and small, are among the many 

 weeds that have obtained a foot- 

 hold in America by smuggling their 

 seeds through the port of entry 

 with those of more important 

 plants. Many of the most com- 

 mon weeds — how many can 

 hardly be known — are those that 

 have emigrated with the white 

 man and have tirelessly followed 

 his footsteps through the New 

 World. Such unwelcome foreign- 

 ers usually take the highways of 

 civilization for their own, and 

 remaining near waysides and in 

 cultivated lands keep the agricul- 

 turist forever busy "plucking up 

 the naughty weeds."
