have been successful) as though the companions of 

 the pine alone were present. The only difference 

 was that the secondary cuttings were made before a 

 complete crop of seedlings of those species was pro- 

 duced, thus enabling the pine to come up in the 

 blanks. 



X. TEEATMENT OF OTHER CONIFERS. 



The spruce fir and the larch, the mountain or 

 dwarf pine, the Corsican, Aleppo, Cembran, and 

 cluster pines, growing either pure or mixed, cover 

 large areas in France. But among these the spruce 

 fir, the larch, and the Cembran and mountain pines 

 almost always occupy such high regions, that it is 

 impossible to treat them by the method of thinnings. 

 In their case, the selection method, which will form 

 the subject of the next chapter, should generally be 

 employed. 



The Corsican pine is chiefly met with in Corsica, 

 where hitherto its exploitation has been carried on 

 only in places, and without any definite rules. But 

 what we know of it leads us to conclude that the 

 treatment adopted for the Scotch pine will suit this 

 species also. 



The Aleppo, and notably the cluster pine, are often 

 cultivated for the sake of the resin they yield. Thus 

 their exploitation is governed by certain rules, which 

 may be found in special works on the subject.* 



The Austrian pine is not indigenous in France, 

 and its introduction amongst us is too recent to 

 permit us to lay down any rules for its treatment. 



* The tapping of the cluster pine for the sake of its resin is fully 

 described in the Supplement.
