SYLVICULTURE. 



On good soil even Spruce is outgrown by it. 



Wood light (spec. grav. 0.35) ! ! 



Seedlings two years old are fit for planting. 



Sensitive against being planted too deep. 



Seed-bed treatment as in A. pectinata. 



I. Abies grandis: Treatment as in pectinata, which it exceeds in 

 height growth. Soil requirements are the same. 



J. Abies nobilis: Frost firm in winter, even unprotected. Late 

 spring shoots help it to escape late frosts. 



Stands dry soil; from fifth year on, more light demanding. 

 Forms strong tap-root, and sometimes several branch whirls per 

 annum. Plantation seven years old is three and one- half feec high. 



Plant seedlings two years old, or transplants four years old. 



K. Pseudotsuga taxifolia: Suitable to any climate, frost proof. 



Soil should not be poorer than third-class Pine soil; no dunes; 

 no swamps. 



Root tap-root on loose soil, flat on shallow soil or binding soil, 

 showing great adaptibility. 



Height growth marvelous! 



Age 5 years height 1.7 feet. 



Age 10 years height 12 feet. 



Age 15 years height 29 feet. 



Age 20 years height 45 feet. 



Age 23 years height 53 feet. 



Diameter, 23 years old, from three inches to ten inches, average 

 seven inches; number of trees per acre 350. 



Close stand required to clear from branches. 



Light and heat demands as- in Picea excelsa. 



Snow and sleet throw it over, or break top shoot, the latter loss 

 being quickly replaced by side shoot taking lead. 



Game is a very bad enemy. 



Use transplants three to four years old. 



L. Chamaecyparis lawsoniana: Does splendidly in Germany 

 especially in the Eifel Mountains at 1,500 feet elevation. 



Frost-proof; but sensitive in drought. 



Exacting like Beech, fond of limestone. 



Flat-rooted; suffers from snow. 



Shade bearing in early youth; fond of half shade later on; 

 always fond of side shade. * 



Slow in clearing itself from side branches; forms very close 

 stands.
