In my next letter I shall give a brief account of a visit to some of the planters, as far as it can be made consistent with the obligations which the rites and rights of hospitality impose on the guest as well as upon the host. These gentlemen are well-bred, courteous, and hospitable. A genuine aristocracy, they have time to cultivate their minds, to apply themselves to politics and the guidance of public affairs. They travel and read, love field-sports, racing, shooting, hunting, and fishing, are bold horsemen, and good shots. But, after all, their state is a modern Sparta--an aristocracy resting on a helotry, and with nothing else to rest upon. Although they profess (and I believe, indeed, sincerely) to hold opinions in opposition to the opening of the slave-trade, it is nevertheless true that the clause in the constitution of the Confederate States which prohibited the importation of negroes was especially and energetically resisted by them, because, as they say, it seemed to be an admission that slavery was in itself an evil and a wrong. Their whole system rests on slavery, and as such they defend it. They entertain very exaggerated ideas of the military strength of their little community, although one may do full justice to its military spirit. Out of their whole population they cannot reckon more than 60,000 adult men by any arithmetic, and as there are nearly 30,000 plantations which must be, according to law, superintended by white men, a considerable number of these adults cannot be spared from the state for service in the open field. The planters boast that they can raise their crops without any inconvenience by the labor of their negroes, and they seem confident that the negroes will work without superintendence. But the experiment is rather dangerous, and it will only be tried in the last extremity. * * * * * SAVANNAH, GA., _May_ 1, 1861.
