SYLVICULTURAL NOTES ON TIMBER TREES continued 



CONIFEROUS TREES. 



OUPRBSSUS. 



Cupressus macrocarpa. 



Cupressus Sitchensis = The Sitka Cypress. 



CUPRESSUS MACROCARPA. 



THIS is native to California, and is said to have been 

 introduced in 1838. 



As to Seed. It ripens seed in this country, but home- 

 grown seed should never be used except experimentally. 

 One pound of seed contains about 73,500 seeds, and the 

 germinative capacity is about 15 to 20 per cent. The tree 

 can be raised from cuttings, but such trees are inadmissible 

 from a sylvicultural point of view. 



The timber is somewhat soft, but of good quality ; and 

 should be equal in value to that of Norway Spruce. 



Soil and Situation. Moist, deep soils are essential for 

 its maximum development. On dry soils, or on shallow 

 soils, it will not thrive. 



It succeeds on stiff clay soils if it escapes spring and 

 autumn frosts, to which it is rather susceptible. It is a very 

 storm-proof tree, and withstands salt sea breezes and gales. 

 It prefers a moist atmosphere, and is often much injured by 

 cold, dry east winds. 



On light, deep, moist, humous soils resting on clay, it 

 succeeds admirably, if only the atmosphere be moist enough.
