Resin-tapping exhausts the larch, so that the resin is collected 

 for a season only at a time, the hole being then stopped with a 

 piece of wood which is removed after a rest of from two to six

 precaution the tree may be tapped for 30 years, or more. 



(b) Tyrolese Method.— In this case (fig. 294) the hole in the 

 larch tree is somewhat larger than the preceding one (3 centi- 

 meters) and is bored either horizontally or at an angle towards 

 the axis of the tree, being then closed by a plug. The resin 

 which accumulates in this hole is removed in autumn by means 

 of a specially made spoon. 



The process is only carried on at intervals, as in the preceding 

 case ; but, though it yields more resin at first, it weakens the tree 

 more than the Htyrian method and cannot be applied for more 

 than 15 to 20 years. 



Tapping the larch for resin yields very little profit to the 

 owner of the trees — viz., about Ul. per tree annually. This 

 is as nothing when compared with the damage caused to 

 the wood; only trees 150 to 200 years old can be thus 

 tapped.
