THE ART OF THE SECOXD GROWTH 



Soil requirements less than in P. excelsa, growing both on sand 

 and on clay. Not in stagnating moisture, but stands inundation 

 well. 



Does well on seashore and at high altitudes. 



Height growth at first very slow; from fifth year on better than 

 in excelsa. 



Short branches, slowly dropped; close stand required, fond of 

 forking. 



No top shade. Side shade welcome but not required. 



Frost and drought not dangerous except during first and second 

 year. 



Game does not bother it. 



Seed-beds of mild, rich soil to strengthen weak seedlings. 



Use strong transplants, five years old. 



G. Abies amabilis: Plants five years old are still subject to 

 damage by direct insolation and by late frosts. 

 Rate of growth as in A. pectinata. 



H. Abies concolor: Spring shoots formed late; resists frosts 

 and any other climatic attacks well. 



Not exacting as to soil, doing well on Scotch Pine soil of second 

 quality, provided that it be fi'esh. 



Tap-root formed in second year. 



Height growth in early youth better than in any other Fir; 

 plants eight years old have average height of three feet. 



On good soil, even Spruce is outgrown by it. 



Seedlings two years old are fit for planting; they suffer when 

 planted too deep. 



Seed-bed treatment as in A. pectinata. 



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

 ceeds 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 whirls of branches 

 per annum. Plantation seven years old is three and one-half feet 

 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.
