For many years the Spaniards threatened the coast as far north as Charleston, but the settlement increased, and extended over St. Helena and other islands. Slavery was here coeval with settlement, and the peculiar institution was so earnestly fostered, that in 1724 it was estimated that South Carolina contained 18,000 slaves to only 14,000 whites. The slaves were mostly natives of Africa of recent importation, and were poorly adapted to clear up the forests and prepare the way for extensive plantations, but their cost was small, and every year they improved in capacity and value. In the succeeding half century were laid the fortunes of the prominent families who have controlled the district, and often greater interests, to our day. Grants of land could be had almost for the asking, especially by men of influence; and fertile islands were given, containing hundreds and sometimes thousands of acres, to a single family, who have here been monarchs of all they survey, including hundreds of slaves, till _the Hegira_ or _flight_ A.D. 1861. When we take into account the salubrity of the climate and the fertility of the soil, we must allow that this district has many natural advantages which can not be excelled by any section of the same extent in this country. A considerable part of the district is composed of islands, which are supposed to be of a comparatively recent formation, many of them beautiful to the eye, and rich in agricultural facilities; they are in number upwards of fifty, not less than thirty of them being of large size. Upon the sea-coast are Reynolds, Prentice, Chaplins, Eddings, Hilton Head, Dawfuskie, Turtle, and the Hunting Islands. Behind these lie St. Helena, Pinckney, Paris, Port Royal, Ladies', Cane, Bermuda, Discane, Bells, Daltha, Coosa, Morgan, Chissolm, Williams Harbor, Kings, Cahoussue, Fording, Barnwell, Whale, Delos, Hall, Lemon, Barrataria, Lopes, Hoy, Savage, Long, Round, and Jones Islands. These are from one to ten miles in length, and usually a proportional half in width. St. Helena is over twenty miles in extent, and could well support an agricultural population of twenty thousand. Port Royal is next in size, but, being of a more sandy formation, is not so fertile. These islands are all of an alluvial formation,--the result of the action of the rivers and the sea. There is no rock of any kind, not even a pebble stone, to be found in the whole district.
