studied. Experiments in the cultivation of various kinds of 

 flowers and their relation to insects may be conducted. Many 

 plant relations to light, heat, and moisture may also be shown 

 in a school garden, under the guidance of the teacher. 



Is a level garden better than one that slopes? Why? Is 

 a steep slope detrimental to a garden? How is the garden 

 supplied with moisture? Why is the ground first plowed or 

 dug up? W'hy is it harrowed or raked? What would be 

 the result of planting seeds without first properly preparing 

 the soil? What care does the garden need after planting? 



Whence come all the weeds found in the garden ? Recall 

 work done on distribution of seeds. Why are weeds detri- 

 mental ? Make a study of some of them. Which thrive and 

 which do not ? Why ? Do weeds serve any useful purpose ? 

 When is the best time to destroy weeds ? 



Many problems will arise and new things will be learned 

 almost every day in watching and caring for a garden. 



t LESSON XLIX 



HOW TO PLANT 



Depth. What seeds may be planted deep? What seeds 

 would not come up if planted deep ? Are there any reasons 

 to guide us as to depth in planting seeds ? What seeds con- 

 tain much food in proportion to the size of the plant ? What 

 seeds contain little food for the plant? Which plants have 

 slender, spear-like stems? Which have blunt or tender 

 stems, ill adapted to penetrate a deep overlay of soil ? 



Wheat, corn, and many other grains may be planted deep, 

 but melon, squash, etc., and the small seeds like lettuce 

 and most flower seeds should be planted shallow, for reasons 

 indicated in the above questions.
