but are mostly formed on the short, thick, wrinkled and 

 crooked branches from wood three or four years old 

 {fruit spurs, Figs. 42 and 43). In some fruits, as the 

 apple, cherry and peach, the flower-buds are usually

In the apple and pear, the buds on the so-called fruit- 

 spurs are not necessarily flower-buds, but some seasons 

 all are leaf-buds. How early in the life of a bud its 

 character is fixed, or if flower-buds ever change to leaf-
