By the use of commercial fertilizers, vast regions once considered barren have been brought into profitable cultivation, and really afford a more reliable and constant crop than the rich alluvial lands of the old slave plantations. In nearly every agricultural county in the South there is to be observed, on the one hand, this section of fertile soils, once the heart of the old civilization, now largely abandoned by the whites, held in tenantry by a dense negro population, full of dilapidation and ruin; while on the other hand, there is the region of light, thin soils, occupied by the small white freeholder, filled with schools, churches, and good roads, and all the elements of a happy, enlightened country life.
