The great cause of emigration from the Atlantic States is to be looked for in the temptation offered the planter by a soil of vastly superior fertility. In South Carolina and in most parts of Georgia, it will appear that a good average crop will give one bale or bag of cotton, weighing 310 lbs. for each working-hand employed on the plantation; now, in Alabama, four or five bales, each weighing 430 lbs. is a fair average for an able-bodied slave engaged in the cultivation; and I have conversed with many planters, holding places upon the bottom-lands of the river, who assured me their crop was yearly ten bales of cotton for each full-grown hand. When it is considered that this season the value of cotton has been ranging from sixpence-halfpenny to ninepence per pound, the enormous receipts of some of these persons, who make from four hundred to three thousand bales of 430 lbs. weight each, may be imagined. These are the men who have been my companions on all my late steamboat trips, for this is the season that affords them _relache_ and brings them together; and in this city especially, as at Natchez, it is by this singular class I am surrounded: they are not difficult to comprehend, and a slight sketch of their condition and habits may not be uninteresting, as they form the great mass now inhabiting this mighty region, and it is from them a probable future population of one hundred million of souls must receive language, habits, and laws. We generally associate with the Southern planter ideas of indolence, inertness of disposition, and a love of luxury and idle expense: nothing, however, can be less characteristic of these frontier tamers of the swamp and of the forest: they are hardy, indefatigable, and enterprising to a degree; despising and contemning luxury and refinement, courting labour, and even making a pride of the privations which they, without any necessity, continue to endure with their families. They are prudent without being at all mean or penurious, and are fond of money without having a tittle of avarice. This may at first sight appear stated from a love of paradox, yet nothing can be more strictly and simply true; this is, in fact, a singular race, and they seem especially endowed by Providence to forward the great work in which they are engaged--to clear the wilderness and lay bare the wealth of this rich country with herculean force and restless perseverance, spurred by a spirit of acquisition no extent of possession can satiate.
