CONDITIONS OF DEVELOPMENT. 

 SOIL AND CLIMATE. 



The Loblolly Pine prefers a moist, cool, sandy or light loamy soil, which, if not always moist, 

 should have a greater retcntiveuess for moisture than is retiuired by most of the other upland 

 pines. It reaches its greatest perfection in the perpetually moi.st or I'resh forest lands, with a soil 

 of a sandy loam, rich in vegetable mold— the accumulation of ages— which border the swamps 

 of the coast region. The tree is not found on the porous, highly siliceous soils of the more 

 elevated uplands, where the Longleaf Pine almost exclusively prevails: it also avoids heavy clay 

 and calcareous soils of the uplands and tlie alluvial lands. 



The Loblolly Pine is a tree of anstr;il regions confined to the humid belt of the Austro-ripariaii 

 or Louisiana zone and the lower border of the Carolinian life zone, which, on the Atlantic Coast,
