INTRODUCTION. 



Ill ig-iiorance of the nature and without appreciation of the economic vahie of their resources, 

 pioneers squamler and destroy witliout regard to the future tlie riches they find. We have done 

 so in the United States and are coutinuino- to do so althougli tlie i)ioneering stage should have 

 been passed, especially with our forest resources. We have exploited them as if they were mines, 

 instead of crops which can be harvested and reproduced continuously, and we have done so in a 

 most wasteful manner; nay, we have by irrational methods of exploitation, no doubt due in part 

 to tlie necessities of a rapidly developing country, in many cases destroyed the conditions for 

 natural reproduction of the more valuable timber species. Fire and iudiscriniiuate pasturing have 

 also assisted in the process of deterioration. 



We are just beginning to realize that our timber supplies are not unlimited; that our 

 maguiticent forest resources have been despoiled and need at least more consideration; that 

 sooner or later forestry will become, nay, is now, a necessity. 



Forestry is the art of producing, numaging, and harvesting wood crops. To be successful iu 

 this art it is of course necessary to understand the nature of the crop — to be acquainted with the 

 life history, the conditions of development re(iuired by each species of tree composing the crop. 

 Such knowledge can be in part, at least, derived from observations made in the natural forests, 

 and from these observations the manner in which the different species should be treated and rules 

 of nuxnagement may be detei'niined. 



The time for the application of forestry— that is, rational methods of treating the wood crop- 

 has not, as nnuiy seem to supi)Ose, come only when the natural forest growths have been despoiled 

 and deteriorated. On the contrary, when the ax is for the first time applied, then is the time for 

 the ap])lication of forestry, for it is possible so to cut the original natural forest crop that it can 

 reproduce itself in a superior nuxnner. The judicious and systematic use of the ax alone, in the 

 hands of the forester, will secure this result. 



Hence these monographs on the life history of the Southern pines have been written primarily 

 to enable the owners of Southeni pineries, who are now engaged in exploiting them, to so modify 

 thcii- treatment of the same as to insure continued reproduction instead of complete exhaustion, 

 which is threatened under present methods. 



The pines are the most important timber trees of the world. They attain this importance 

 from a combination of properties. In the first place, tliey possess such (lualitics of strength and 

 elasticity, combiued with comparatively light weight and ease of working, as to fit them specially 

 for use in construction which requires the largest amount of wood; next, they occur as forests in 

 the temperate zones, often to the exclnsion of every other species, so that their exploitation is 

 ma;le easy and profitable; thirdly, they are readily reproduced and tolerably (juick growers; and, 

 lastly, they occupy the poorest soils, producing valuable crops from the dry sands, and hence are 

 of the greatest value from the standpoint of national economy. 



The Southern States abound iu those sandy soils which are the home of the pine tribes and 

 were once covered with seemingly boundless forests of the same. There are still large areas 

 untouched, yet the greater portion of the primeval forest has not only been culled of its best 

 timber, but the repeated conflagrations which follow the lumbering, and, still more disastrously, 

 the turpentine gatherers' operations have destroyed notonly the remainder of tin; original growth, 

 but the vegetalde mold and the young aftergrowth, leaving thousands of square miles as blackened 

 wastes, devoid of usefulness, and retlucing by so much the potential wealth of the South. 



There are, in general, four belts of pine forest of different types recognizable, their boundaries 

 running in general direction somewhat parallel to the coast line: (1) The coast plain, or pinebarreii 

 flats, within the tidewater region, 10 to 30 miles wide, once occupied mainly by the most valuable
