LESSONS FROM THE FOREST 



51 



In a cross section of a tree we can see pith, pith rays, rings of 

 growth, heart wood, sap wood, and bark. 



PRACTICAL EXERCISES. 



1. Identifying Trees. Let the class in Agriculture take a walk 

 with the teacher among the trees. Each pupil should have note-hook 

 and pencil. Let the teacher point out the trees and give each tree 

 a number. Let each pupil take down the number and opposite the 

 number, write down the kind of tree he thinks it is. After naming 

 a dozen or more trees, return to the school house or be seated any- 

 where and check up each of the pupil's list with the teacher's correct 

 names. This exercise may be repeated until the pupils know all the 



.trees in the vicinity. 



2. Reports on Individual Trees. Assign to each pupil a single 

 species of tree and require the following table filled out, from obser- 

 vational study: 



"The leaves are swept from 



the branches, 

 But the living buds are 



there, 



With folded flower and foli- 

 age, 



To sprout in a kinder air."
