afford excellent contrasts. Contrast the Bartlett with the Flem- 

 ish Beauty, the Kiefferwith the Seckel. In apples, compare the 

 Baldwin with the Spy, the King witli the Twenty Ounce. The 



sweet and sour cherries 

 show marked differences 

 in method of branching. 

 Fruit men can tell many 

 varieties apart in win- 

 ter : how? 



Two common hickor- 

 ies are shown in Figs. 

 25 and 26. How do they 

 differ? Do they differ 

 in length of trunk? 

 General method of 

 branching ? Direction 

 of branches? Character 

 of twig growth? 

 Straightness or crooked- 

 ness of branches ? 



Contrast the slippery 

 elm (Fig. 27) and the 

 common or American 

 elm (Fig. 34). The 

 former has a crotchy or 

 forked growth, and long, 

 stiff wide- spreading 

 branches. The latter is 

 more vase-like in shape. 

 The branches are wil- 

 lowy and graceful, with 

 a tendency- to weep. 

 Compare the oaks. The white and scarlet oaks have short 

 trunks when the}' grow in fields, and the main branches are com- 

 paratively few and make bold angles and curves. The swamp 

 white oak (Fig. 28), however, has a more continuous trunk, with 

 many comparatively small, horizontal and tortuous branches. 

 With Fig. 28 compare the pepperidge (Fig. 29). This is one
