BRANCHES. 



stances than others. Thus we have erect branches (fig. 4), 

 which produce trees of an upright and compact form. 

 Curved erect branches (fig. 5), proceeding almost horizon- 

 tally from the stem for a short distance, and then becoming 

 erect; these, also, form upright symmetrical heads, but 

 much more open than the preceding. Also, horizontal, 

 or spreading branches (fig. 6), that form wide-spreading

heads with irregular outline. And, lastly, drooping 

 branches, when they fall below the horizontal line. The 

 branches of most varieties of apples and pears become 

 pendulous when they have borne for some time ; and even 

 in young trees of particular varieties, some of the branches 

 assume a drooping and irregular habit. 



2d. Secondary Branches ( 6r, fig. 1), are the divisions 

 of the main branches : occasionally those near the stem 

 take such a prominent part in forming the outline of the 

 tree, as to assume all the character of main branches, ex- 

 cepting in position.
