pest will be introduced, and it is very desirable that the 

 people of each community should be on the alert for such 

 newly introduced weeds. In order that they may do this, 

 each school should have a collection of weeds and their 

 seeds for reference, and a study should be made of the 

 weedy plants of the locality. Any unknown plants may 

 be sent to the State Experiment Station, or to the Depart- 

 ment of Agriculture at Washington for determination. 



OBSERVATIONS FOR PUPILS 



1 . What weeds have you observed in connection with such of the 

 following crops as are largely grown in your locality : 



Alfalfa 



Alsike Clover 



Oats 



Red Clover 



Wheat 



2. Is there any evidence to show that part of these were introduced 

 with seed ? 



3. Examine with a lens samples of forage plant seeds for sale in your 

 locality. Compare the seeds with the pictures in Farmers' Bulletin 382. 



4. Determine the percentage of adulteration of the crop seed with 

 other seeds. 



5. If you are unable to determine what seeds are present as adul- 

 terants, send samples to your State Experiment Station or to the Seed 

 Laboratory, Department of Agriculture, Washington, D.C.
