principal point to be noticed is that it is rather heavy 

 at the end and therefore lies easily in the hand. By 

 reason of this heavy construction, it is more suitable 

 for pushing than for drawing than is the Jebong knife. 

 On one estate which I visited, inexperienced workmen 

 were given the push and pull knife to practise tapping 

 with, the experienced coolies received the gouge. 



There still remains to be described the marker (fig. 

 38^) which was originally made for tapping purposes, 

 but is now exclusively in use for setting out the tapping 

 lines. It consists of a handle in which is set a bar, bent 

 and terminating in a wedge shaped head with an opening

made through it. The edges of the opening are sharpened 

 so that the head can easily be drawn through the bark. 

 The cutting edges rip open the bark, and the strip 

 which is cut away falls through the opening in the head. 

 There are other types of tapping tools which only 

 differ in a slight degree from those mentioned above, 

 such as those, for instance, in which the cutting edge 

 and shank are in one piece, and again those in \vhich 

 the whole tool is of a lighter construction than the 

 ordinary push and pull knife. These, however, need not 

 be more fully described here, they are fully described 

 in the catalogues of dealers in such articles.
