SYLVICULTURE. 



Birch is sensitive to deep planting; is not affected by heat, frost 

 or drought. 



Ash: The easiest species among hardwoods to raise, plant and 

 transplant. Planted as a seedling one year old or transplanted up 

 to three times. Plants as old as eight years can be planted suc- 

 'cessfully without balls. Seed is placed in rills seven to twelve 

 irches apart. Where soil is very weedy, large and strong trans- 

 plants must be used. Planting in holes, on mounds or in furrows. 

 The cleft spade is also penuissible in planting yearlings. Trimming 

 is not advisable, except to prevent formation of forks. Transplant- 

 n^ of germs, in June, is quite successful. 



Elm: Seeds to be planted in summer (excepting Slippery 

 >.lms), just after ripening, in rich nurseries, and to receive very 

 light cover of sand. Seed beds must be sprinkled, and the forma- 

 tion of a crust must be prevented. Seedlings cannot penetrate 

 a layer of one-half an inch of dirt. Usually, transplants three to 

 five years old arp ".sed. Fall planting is preferred. Elms stand 

 trimming easily. 



Maple: Drills lluee-fovu'th inches deep, one inch wide, twelve 

 Inches apart. Transplanting takes place when seedlings are one 

 or two years old. Seedlings grow i-apidly. Fall planting is pre- 

 ferable. Planting in large holes is best, since Maple can- 

 not form a compact root system. Sugar Maple planted at 

 Biltmore on abandoned fields four years old did very well on 

 North Slopes, in pure stands as well as mixed with White Pine. 

 Maple is easily transplanted, and even yearlings or two year olds 

 might be planted in the open on good soil. In swamps. Red and 

 Soft Maple are preferable. Sugar Maple requires well drained 

 Boil. 



Yellow Poplar: Very poor seeds, hence broadcast planting. Cov- 

 ering with spent sawdust, instead of dirt, seems advisable. Seed- 

 lings transplanted either as germs in first summer or when one 

 year old. Very rapid growth in first and second year. Easily 

 transplanted in holes on suitable soil. Seedlings can be taken in 

 June and July from wood roads to the nurseries, with balls of 

 dirt. Abandoned fields at Biltmore, planted with four year olds 

 did poorly except in northern depressions. Strong soil needed. 

 Compact soil not unfavorable. 



Catalpa: The favorite Kansas prairie tree. Very high germinat- 

 ing percentage. Very fast growth in first year. Rills one inch 

 by one inch by twelve inches. Seedling plants one year old are 

 strong enough for planting. Stump plant-s are preferable. At
