706 PROPERTIES, HARVESTING AND DISPOSAL OF RESIN. 



gradually to the interior of the wood, which becomes charged 

 with resin. Eesinised wood, owing to its easy combustibility, 

 is excellent for kindling purposes, and in mountain districts 

 abroad is still employed for torches. For this purpose stems 

 were peeled of bark in order to induce resinosis. [Brandis 

 states (Forest Flora of N.W. and Central India, 1874) that 

 " the wood of stumps of trees of Pinus longifolia, in the 

 Himalayas, which have been notched and mutilated, is often so 

 full of resin as to be translucent, and such wood is used for 

 torches, and in place of candles, in houses and mines." Tr.] 

 Nowadays resinous wood is produced by the fungi mentioned 

 above, or as a bye-product of resin-tapping. 



SECTION IV. KESIN-TAPPING OF STANDING TREES. 



The method employed for resin-tapping depends on the 

 species of tree and on the part of the tree from which the 

 resin is taken. In order to avoid repetition, the reader is 

 referred to the anatomical discussion that has preceded. 



* Among European species, the maritime or cluster pine 

 (Pinus Pinaster, Soland.) may be tapped most advantageously 

 for resin ; this pine yields resin most abundantly near the 

 sea-coast between Bayonne and the mouth of Charente, chiefly 

 among the sand-dunes and landes (waste, sandy tracts) of 

 Gascony. In other parts of France, where the maritime pine 

 grows either naturally or artificially, resin- tapping is not 

 sufficiently remunerative to be practised. 



Although other European conifers also yield resin, they do 

 not furnish it in sufficient quantities for resin-tapping in 

 their case to become a regular industi\y. In France, at any 

 rate, their wood is too valuable to be exposed to the damage 

 which the operation causes. However, as the silver-fir, spruce, 

 larch, black pine and Aleppo-pine are sometimes tapped, it is 

 useful to know how this is done. The Scots, mountain and 

 Cembran pines are not tapped. 



According to Sargent, the principal world-supply of oleo- 

 resin comes from the long-leaved pine (Pinus palnstris) and 



* The rot of this >ceti<>n is taken rhiclly from Uoppc's 

 forestifere."
