optimum conditions for the development of individual trees of 

 loblolly jiinc are offered by sites 8 and 9, on which occur trees of large 

 size either in small groups or scattered singly among the hardwoods. 



I'timum conditions for the development of pure stands are offered 

 sit os there is less competition from the hard- 



woods and loblolly pine is truly gregarious, dominating to the practical 

 'usion of other trees. 



.veen the typical conditions there are gradations of all kinds. 

 When the forest is lumbered or severely burned, its distinctive char- 

 acters are often almost obliterated, though the constant tendency, when 

 natural forces are permitted to re-assert themselves, is for the reestab- 

 li-hnient of the original forest type. Near the coast, a number of these 

 conditions will sometimes be represented on an area of less than an acre. 

 In addition to the above original or permanent types there are four 

 important temporary types: (1) mixed oak and hickory, which have 

 followed pine on loams and clays; (2) Quercus Margaretta and round- 

 leaf blackjack oak, which have followed pine on dry sandy loams; (3) 

 sand blackjack oak which has followed longleaf pine on sand hills ; 

 (4) loblolly pine in old fields and on cut-over longjleaf pine land. 



pure stands of loblolly in old fields and on cut-over longleaf pine 



;nc very extensive, jmd occupy all classes of soils; they are of all 

 ages and are in every condition of thrift and density, and constitute an 

 important source of pine timber. 



The conditions under which the loblolly pine occurs, as shown in 



1. may be grouped for convenience under seven heads as follows: 



Old field growth on dry si 

 (2) Loblolly pine in pure stands on porous loams ;ind peaty soils 



(TaMc 1. numbers 7 and 10, in part) ; 

 Loblolly pine on longleaf pine flat lands (Table 1, numbers 4 



to 6); 



Loblolly pine with hardwoods in swamps chiefly in the coital 

 plain (Table 1, numbers 8 an< 



'oily pine with pocoson pine on -av;mna< (Table 1, numbers
