REVIEW OF THE BOOK 313 



What is the proper seed-bed for potatoes? Should they be 

 planted deep or shallow? Should they be grown in level culture 

 or on ridges? 



Chapter 11 



Having now discussed the preparation of the 

 seed-bed and the starting of the crop, we may 

 give attention to some of the principles that 

 underlie the subsequent care of the plant. This

W T hat is the first consideration in the care of the plant? 

 What are the objects of tillage? What can you say about weeds? 

 Name some of the general means of keeping weeds in check. 

 How often should surface tillage be given? Is it ever practicable 

 to till sowed crops? How late may it be advisable to till corn by 

 means of harrows? 



Is tillage advisable in fruit plantations? Why is it that fruit 

 plantations may do better without tillage than corn or potatoes 

 do? Why is it very important to till fruit plantations early in 

 life? May the orchard need clean tillage throughout its whole

 Should fruit plantations be tilled uniformly throughout the entire 

 season? Explain a good general method for the tillage of fruit 

 lands. 



What is pruning? Training? Is pruning unnatural? Explain 

 by reference to a tree top what is meant by the phrase "struggle

Explain how wounds heal. What are some of the factors that
