 general growth of the tree or shrub as to form and de- 

 velopment, must consider the way in which blossom buds 

 are produced so he can intelligently regulate the number 

 and development of the buds, twigs and branches which

 and fruits. The following 

 paragraphs will, therefore, 

 help the uninstructed 

 reader to determine how to 

 make decisions so far as 

 buds are concerned.

 pruning practice it is often 

 necessary to know the age 

 of branches and twigs. Ex- 

 cept where secondary 

 growth has taken place this 

 can easily be determined

 and a bulge. These may 

 not, however, be as marked 

 in this case as in normal 

 cases. When the terminal

 usually kills back to the 

 first sturdy lateral twig,

 apple and pear fruit spurs which are often three times 

 the diameter of the twigs below the swellings. The 

 scars were left by the bud scales which fell off when the 

 terminal bud pushed into growth. When the terminals
