CHAPTER X. 

 The practical work of Tapping. 



I. SETTING OUT THE TAPPING LINES. 



In the first place, a definite working- scheme has to be 

 made up, having regard to the age, the sections of 

 surface, and the special system on which the trees are 

 to be tapped. As soon as a garden has attained the 

 stipulated age, a competent man will have to measure 

 the trees and mark all of them which possess the 

 required girth. 



The tapping lines will then have to be set out on 

 these trees. It is of much importance to do this very 

 carefully. The aim will be to tap off as regularly as 

 possible the whole surface of the bark and this is only 

 feasible if it is clearly laid down beforehand which 

 sections of the trunk are going to be tapped, in which 

 direction the cuts are to be run and in what terminals 

 they are to end. 



When previously tapped trees are to be tapped again, 

 the new tapping cuts should be drawn as much as 

 possible in the same direction as the old ones; if this 

 is not done, then the new tapping cuts intersect the old 

 ones, i. e. bark of different age and different thickness.
