axillary buds upon the shoot between c and d. 

 Another fruit was borne at b. While this latter 

 fruit was growing, side shoots started off in two

 g. During the following winter the tip of the 

 branch g died, and in the spring two shoots 

 sprung from it, one growing to d and bearing 

 a fruit, and the other to e and not bearing. 

 The branch 1) f made a number of lateral shoots, 

 for its tip also had died before the growing sea- 

 son began. The twig 48, then, is four years old.
