times done, they should be removed to the ground after Water- 

 blooming. This allows them to regain strength, and 

 unless this is done they will either not bloom at all or 

 bloom very poorly during the next year. Whenever 

 the water in which house bulbs are grown is changed, it 

 is well to add a few drops of ammonia. The ammonia 

 will supply the plants with nitrogen and make their 

 growth more vigorous. 



Experiments and Observations 



1. Sketch a plan for the grounds around a house, showing 

 walks and the locations of the different kinds of trees, shrubs, 

 and flowers. What do you think of the plan given in Figure 115 ? 



2. Look carefully at the grounds of some public building in or 

 near your neighborhood and report to the class on the arrange- 

 ment of trees, shrubs, etc. Tell what improvements, if any, you 

 think might be made. (The grounds about some home might 

 be considered to better advantage if there were no danger of giv- 

 ing offense.)
