398 SYLVICULTURAL NOTES ON TIMBER TREES 



siderably faster when young, but, usually, gets caught up by 

 the European species after about the 2Oth year. When quite 

 young, it will often keep pace with Douglas Fir or Poplars. 

 Up to the present time, it has proved much more immune to 

 insect and fungous attacks than the European variety, and, as 

 already stated, it has hardly ever been attacked by the. Larch 

 disease or canker. 



Its foliage is flushed early, and it is even more liable to be 

 injured by spring frosts than European Larch. 



The chief advantage in growing Japanese Larch lies in 

 the fact that they very quickly afford valuable thinnings ; and, 

 if necessary, mature trees can be grown, even though the 

 European Larch would fail owing to disease. 



However, the Japanese Larch is more expensive to raise 

 from seed than the European Larch. 



An excellent plan is to grow a mixture of the two species, 

 and if disease do not make its appearance, the European 

 variety should be left ; for these trees will, as mature timber, 

 give far better returns. The Japanese Larch grow faster 

 when young, but usually they will not seriously interfere 

 with the European Larch. 



OTHER LARCHES. 



The Western Larch is a tree native to British Columbia. 

 Little, however, is known concerning its growth in this 

 country. It should be largely experimented with, as there is 

 every possibility of its proving most successful indeed. 



In its native country it grows to a great height, and the 

 boles are usually very clean. It is peculiar in possessing a 

 very thick bark, which often enables it to resist destruction 

 by forest fires. 



The Kurile Larch is native to the Kurile Islands, in the 

 north-east of Japan. 



It is of little sylvicultural value in this country, as it does 

 not ultimately form such a large tree as the European 

 variety, and it is very expensive to raise. 



It is usually very quick growing when young, and is said
