Watch apple buds. The scales do not elongate as in the pear 

 but the flower-buds are mixed. Fig. 63 shows the expandino- cluster 

 from an apple flower-bud. Four flowers will open ; and there are 

 six leaves. If the buds are 

 made to open in the house on 

 severed twigs, the leaves do 

 not grow so large before the 

 flowers expand, for the twig 

 does not contain sufticient food. 

 Fig. 64 is a photograph of an 

 apple twig which I had in my 

 window one winter's day.

Examine a hickory twig. 

 The illustration (Fig. 65) shows 



beginning of the annual 

 growth. See the large 

 leaf- scars. Xotice that 

 the terminal bud is much 

 the largest. It is the one 

 which M'ill oTOw. The 

 other buds will remain 

 dormant unless they are 

 forced into growth by the 

 death of the terminal bud 

 or by other unusual cir- 

 cumstance. Notice that 

 buds differ in size on 

 shoots of all plants : con- 

 sider that not all the buds 

 are to grow : there is 

 struo-o-le for existence. 

 When the hickory bud 

 expands, some of the scales fall away ; but some of the inner parts 

 enlarge into leaf-like bodies, as shown in Fig. QQ. In some hick- 

 ories these bodies become two or three inches long before they fall.
