protect the younger leaves or the bud, the smallest child 

 can see and understand fairly well. 



LESSON XII. THE STORY OF THE LEAF AND OF ITS 

 WORK. A REVIEW. 



Cannot the life and work of the leaf from infancy to 

 maturity be summarized, more closely related, and more 

 deeply impressed by a story, The Story Our Bean Leaf 

 Told " ? Let the children help by supplying to the teacher 

 who has forgotten (? ) them some of the main inci- 

 dents of the story. 



GERMINATION OF MORNING GLORY. 



( Continued from April. Planned for Third Grade. ) 



The Morning-Glory Leaves and their Work. Follow 

 much the same general line of work as outlined for the 

 study of the bean. 



Watch carefully the growth of the stem and the way in 

 which it twines around the string provided for it, compar- 

 ing its growth and manner of supporting itself with the 

 bean or pea. 



Observe the position of the bud, between the bases of 

 the seed leaves, the protection, first appearance, and growth 

 of the true leaves, the ways in which they differ from the 

 seed leaves or cotyledons, the position and unfolding of 

 new buds and leaves. Note how the seed leaves change 

 color, and finally drop off. 



Third-grade children should be able to draw the morning- 

 glory leaf with very little help. The best way to lead 

 the children to observe the leaf, and to get a clear, exact 

 idea of it, is to have each pupil draw a leaf. 



Bring out by experiment do not merely talk about 

 the use of the morning-glory leaves. (See outline on bean.)
