/A man buys a lot at the edge of Oxford. It is a lot one hundred 

 feet wide and one hundred and fifty feet deep. There are no 

 shade trees on the lot. 



Problem : How can this man provide shade for his lot so as to 

 make it most valuable twenty years from now ? 



1 . What trees shall he plant ? 



(Let the children make suggestions. If they suggest the elm 

 then the question.) 



1. Why plant the elm? Why not? Ref. 5, pp. 233-240. 



Ref. 6, pp. 230-233. 

 Ref. 11, pp. 38-41. 



(If they suggest that the elm is pretty, makes good shade, is 

 strong, etc., the following questions arise.) 



1 . Why do you think the elm a beautiful tree in the fall ? spring? 

 winter? summer? 



2 . What reasons have you for believing it to be a strong tree ? 



3. What kind of shade does it give? 



4. What care does it require? 



5. How rapidly does it grow? 



1. What are the advantages and disadvantages of planting 

 the elm on this lot ? 



*Conclusion: Solotariff says, "No other tree combines such 

 strength with so much grace." Because of its beauty, strength, 

 and abundant shade it is a great favorite. The elm is beautiful 

 at all seasons of the year. "In summer it rises like a great foun- 

 tain of green." "Ever}- chink is filled with a leaf." In autumn 

 these leaves turn brown or a golden yellow. In winter we can 

 appreciate the beauty of its arching limbs, pendulous branches, 



*In substance children should reach the conclusions suggested.
