Which has the greater store of nourishment? 

 Why should that be so ? What becomes of the 

 scaly covering as the bud unfolds ? Watch closely 

 the hickory bud so as to know what is done with 

 the scales. Do the outer coverings of all buds 

 do as the hickory scales do ? What change in 

 color of the outer covering in the cherry 

 or apple buds? Where is the flower bud 

 found in cherry? Examine both lateral and 

 terminal buds and note that the latter as a rule do 

 not bear flowers, but leaves. Put twigs in a jar of 

 water and watch the flowers come out from the 

 lateral, but not often from the terminal buds. 



Have the children observe the scale scars of last 

 year, and notice that when the scales of this year 

 fall off they will leave the same kind of scar, a 

 sort of scar ring, around the twig or branch. 

 How often then do these scars or rings appear? 

 Answer: — ^As often as the bud scales fall off, which 

 is usually once a year. Then if a branch has four 

 of these rings, how old is it ? Then can we tell 

 the age of a branch ? How ? There are excep- 

 tions to this rule but it will not be necessary to 

 mention them here.

 well completed, attention may be called to the
