EXERCISE 34 (Continued) 



have you found that the lateral buds open ? If so, what do they 

 produce ? On the older parts of the branch which you have 

 been examining are there any evidences of growth from lateral 

 buds ? What have the lateral buds produced ? Determine, by 

 examination of the twig, when each of these buds began to 

 grow. Do the buds open during their first season ; that is, with- 

 out having spent a winter in the resting condition ? 



Other well-marked scars are often found on branches. These 

 may be scars left by fruit or flowers, and they vary greatly in 

 size and position in different kinds of trees. Scars due to 

 injuries may be present also. 



Draw a line to represent the branch you have been studying 

 and mark the end of each year's growth. Indicate in figures 

 the year in which each section grew. In like manner add the 

 secondary branches and indicate their annual growth. 



Set down in your notes all the facts to which your attention 

 has been called in this study or which you have observed in- 

 dependently. ' Then write a connected story of the growth of 

 the particular branch you have been studying.
