118 A STUDY OF FOREST CONDITIONS 



strips should be logged clean, with the expectation that 

 young growth will start up from seeds from the strips of 

 forest land on either side. When a sufficiently dense 

 stand of reproduction is secured and the young trees have 

 begun to bear seed, in fifteen to twenty-five years' time, the 

 remaining strips should be lumbered in the same way, when 

 the area would in turn be seeded from the young trees. 

 The advantages of this method are: the stand can be cut 

 clean, the trees left in the strips will be less likely to be 

 wind-thrown, and the cost of the second cutting will not 

 exceed the cost of the first. The cost of logging will be 

 lessened, as the logs will be skidded only half the distance, 

 but this may be counterbalanced in certain cases, by the 

 increased cost of spur construction per 1,000 feet of timber 

 logged. The chief objection is that so much timber musL 

 be left for the second crop. 



Loblolly and Longleaf Subtype. — In this type loblolly 

 pine should be encouraged in every way possible, the object 

 being to substitute this rapid-growing tree for the slower 

 growing longleaf on all suitable areas. Wherever there is 

 any young growth the selection method of cutting should be 

 practiced, leaving all young, rapidly-growing trees on the 

 ground. This is advisable, because young loblolly pine 

 grown in an open stand, makes a poor quality of lumber. 

 It produces good lumber only when grown in a dense stand, 

 and it will grow in this way only if fire is kept out. Where 

 three or four well-distributed seed trees per acre of loblolly 

 can be secured, no longleaf seed trees need be left. The 

 seeds of the loblolly being much lighter than those of the 

 longleaf are scattered farther by the wind, and seed years 

 being so much more frequent, fewer seed trees are necessary. 



In all types which contain longleaf, considerable fore- 

 sight is necessary where turpentining is practiced. This 

 operation usually commences three or four years ahead of 

 the lumbering in order to include the most profitable period 

 for boxing the trees. Trees necessary for seed trees and all 

 second growth that is to be left should be selected before 

 turpentining begins, or else a diameter limit should be set 

 large enough to include the trees to be saved. These trees
