CONDITIONS OF nEVELOPMENT. 



Soil and climate— ThG Sliortleaf Pine prefers ;i well-diained, lij^lit sandy or iiravelly clay soil 

 or warm loam, even if deficient in the elements of plant food. Soils of this character which are 

 found widely prevailing over the undulating or broken uplands, if only of sufficient depth, will 

 produce this tree in greatest perfection. It avoids the strongly calcareous and the rich alluvial 

 soils, as well as purely silicious, being dependent on the presence of a certain amount of clay by 

 which the mechanical condition of the soil is improved, rendering it more compact ami more
