An estimate of the number of plantations open to cultivation, and of the persons upon the territory protected by the forces of the United States, if only approximate to the truth, may prove convenient in providing a proper system of administration. The following islands are thus protected, and the estimated number of plantations upon each is given:
Or about two hundred in all.

There are several other islands thus protected, without plantations, as Otter, Pritchard, Fripp, Hunting and Phillips. Lemon and Daw have not been explored by the agents engaged in collecting cotton. The populous island of North Edisto, lying in the direction of Charleston, and giving the name to the finest cotton, is still visited by the rebels. A part near Botany Bay Island is commanded by the guns of one of our war vessels, under which a colony of one thousand negroes sought protection, where they have been temporarily subsisted from its stores. The number has within a few days been stated to have increased to 2300.
