THE ART OF THE SECOND GROWTH 



and market. Its applicability, however, rests on the existence of 

 some permanent chief arteries of transportation. 



At Biltmore, the type is applied, in modified form, for the 

 reproduction of Yellow Poplar and Yellow Pine. 



C. Advantages of tte cleared strip type: 



I. Applicability to many species, to many conditions and to 

 many localities. 



II. Concentration of logging operations; sylvicultural help possi- 

 ble; cheap logging by donkey engines, chutes, snaking, etc. 



III. Many points of attack, at which tlie season's cut might 

 be obtained, are at the disposal of the forester, if he so desires. 

 Hence great freedom of action. 



IV. Comparative safety of the old woods from storm; of the 

 young growth from fire, drought, frost, insects, etc. 



D. Disadvantages of tte cleared strip type: 



I. If the seeding of the strip is not effected soon after clear- 

 ing, the soil is baked by the sun, weeds are started and the 

 ecological conditions are affected in a manner barring the success 

 of seed regeneration and necessitating artificial help. 



II. Border trees are exposed to sim scald. 



III. Animals frequent the strips and spoil the young growth. 



IV. The soil of the strip — especially of the first strip in a 

 series — is rarely " in heat," certainly not over the entire strip, 

 so that the seeds falling upon it have a poor chance of success. 

 This is the case, preeminently, in the humid mountains whei'e a 

 heavy layer of raw humus covers the ground. A large number of 

 years will often elapse, before the next adjoining strip can be 

 taken in hand. 



V. The strips should be cut where the timber is most mature 

 at the time, — and not in a succession merely dependent on the con- 

 dition of the young growth and on the necessity of proceeding 

 against the prevailing storm direction. 



Paragraph XLV. The cleared ^roup type. 



A. The groups cut comprise from 0.1 acre to four acres. 



The form is roimdish, oval, square, etc., as the case may be, usually 

 coinciding with a geological feature, e. g., a dell, a spur, a spring- 

 head. 



The incentive for group-cutting lies either in the simultaneous 

 maturity of the trees stocking on it, or in the desire to obtain 

 conditions particularly favorable to the reproduction of one of the
