THE WOODS IN THEIR SUMMER FOLIAGE. 

 SEPTEMBER 



44. The Leaves of our Trees and Shrubs. 



MATERIAL: A walk into the woods, or observations on trees and 

 shrubs in parks and along streets, should precede this lesson. Leaves 

 or leafy twigs of all plants to be mentioned ; press and keep leaves of 

 all. Preserve also a large variety of leaves injured by insects in various 

 ways. 



Most teachers probably have no time to study the leaves more in 

 detail. The few new terms used should be explained as they occur, 

 and should be thoroughly understood by the children. Let them 

 describe the leaves as they see them. 



All our trees have had their fully developed foliage for 

 several months ; some are still producing young leaves, but 

 most of them have only full-sized leaves. You must have 

 observed that it is much more difficult now to see the 

 branches and twigs distinctly than it was in March and 

 April. The birds also know that the leaves protect their 

 nests from intruders, and they do not build them until the 

 leaves are out. It is easy, in early spring, to find the old 

 nests, but not so easy to find the new ones in May and June. 



Although the leaves we collected show a great variety of 

 forms, we can nevertheless arrange them for comparison 

 in a few groups. 



1. The leaves of elms, of the hazel, the dogwoods, the 

 chokecherry, and the ironwood are more or less oval in 



Observations. Notice the beginning of autumn colors on foliage, and 

 watch its increase.
