 best only allowed to grow,) at each of the points b b b h, so 

 that strong upright shoots are now growing, as indicated by 

 dotted lines, for a crop next season. Bunches of fruit will 

 form on these the present year, but they must be rubbed off 

 early, that the vigor of these shoots may not be retarded. 



In this way, a constant succession is kept up. 



The two right hand fruit-spurs in fig. 311, show the ordi- 

 nary length they are allowed to grow before the ends are 

 pinched off, the upper one being already shortened, and the 

 lower showing the point at c where it should be nipped. 



It must never be forgotten that the full growth and 'per- 

 fect, ripening of the fruit, depends wholly on healthy, well 

 developed leaves, to furnish food to the forming berries. 

 Hence they must have plenty of room, light and air for their 

 healthy development. And hence too, the entire error of 

 the practice of picking off the leaves to let in the light on 

 the fruit. The longer the shoots or spurs extend themselves 

 the better, before they are pinched off, provided they do not 

 interfere with each other.
