portant as a clean conscience ? Can a farmer have the first without 

 the second? 12. Why should farmers cooperate in weed control? 



HOME EXERCISES 



1. Ask your father for a description of all the different methods 

 he uses to destroy his weeds. Which weed does he think is the worst 

 one on his farm? Why is 



this weed so objectionable? 

 How does it multiply, and 

 how do you think it can best 

 be controlled ? 



2. Write a short account 

 on " How I kept my Plot 

 Free from Weeds." 



SUGGESTIONS 



1. Pupils should be asked 

 to bring to school a few of 

 the worst weeds on the farm. 

 It is no discredit if the 

 teacher does not know the 

 names of all of them. There 

 are over 200,000 different 

 kinds of plants known, and 

 no one can recognize them all. 

 A good plan would be to send 

 those plants whose correct 

 names are not known in the 

 community to the State 

 College, for identification and 



for special information on how to get rid of them. 



2. There should be some practical work done in the eradication of 

 weeds. The effectiveness of the various methods outlined in this 

 chapter can be demonstrated on common weeds by the teacher.
