XIX. PINE LEAVES 



Material. Leafy branches from several kinds of pine trees. 



Observation. From what kind of pine were the 

 leaves that you are studying taken ? What is the 

 shape of one of the leaves? How many inches long 

 is it? What is its color? What is its odor? What 

 is its taste ? How many leaves grow together in a 

 group ? Is there a wrapping around the base of each 

 group of leaves ? How far up on the leaves does the 

 wrapping extend ? What is the wrapping like ? 



Has a pine twig more or fewer leaves than an 

 apple twig of the same size ? Do pine leaves grow 

 nearer together or farther apart than apple leaves? 

 On what part of last year's growth of wood do you 

 find leaves ? 



Are there any leaves on two-year-old pine wood ? 

 Are there any on three-year-old wood ? How old 

 are pine leaves when they fall ? What kind of scars 

 do they leave on the bark ? 



Drawing. Draw a picture of pine leaves in their 

 natural size, showing how they grow together in 

 groups. Draw the wrapping if there is any. 



Draw a picture of a pine twig, showing how the
