THE ART OF THE SECOND GROWTH 



B. The coincidence of the compass diiection in which the 

 clearing lies from tlie adjoining woods, with the direction of the 

 wind preferably ojiening the cones and carrying the seed. 



C. The local danger from storm which might tear down, 

 gradually at least, the adjoining seed trees. 



D. The condition of the cleared soil and its quality as a 

 ready seed-bed, influenced by the presence of weeds; by the de- 

 composition of the humus; by the degree in which the mineral 

 soil has been laid bare in the course of logging operations; by the 

 grade of the slope. 



E. Fires favorable or unfavorable; pasture favorable 

 or unfavorable to regeneration, as the case may be. 



F. The frequency of seed years, and the possibility of 

 lumbering during a seed year. 



G. The size, the form and the environments of the area 

 cut over. 



H. The possibility of preventing undesirable species 



(Gums, Black Jack Oak) and undesirable specimens, like low- 

 branched weed trees and spreading "wolves," from occupying the 

 area to be regenerated, and the possibility of regenerating all, a 

 few, or only one species. 



According to the size of the clearing, we distinguish between: 



The cleared compartment type (large areas cleared) ; 



The cleared strip type (narrow belts cleared) ; 



The cleared group type (fair sized groups cleared away); 



The cleared selection type (small bunches of trees or merely 

 single trees cut). 



Paragraph XLIII. The cleared compartment 

 type. 



A. The area bared at one stroke by lumbering comprises 

 between, say, ten and one hundred acres. If the width of the 

 clearing is less than 500 feer., the "cleared strip" type is reached. 

 If the acreage cleared is much in excess of 100 acres, the develop- 

 ment of a second growth is very slow, very poor, very doubtful, 

 so that the character of a sylvicultural type is lost. A number 

 (say five) of seed years are required to restock the ground. The 

 bordering woods, from which reseeding is expected, must not offer 

 an unprotected front to the prevailing storm direction.
