The campaign now presumed to be inaugurating in South Carolina gives a peculiar interest to everything connected with that “emphatic State,” as Mr. Sumner terms the mother of Secession. In another part of our paper we publish some sketches of what the Confederates have done to protect Charleston harbor from Union attack. Our sketches of Port Royal are of a different kind, and show what the authorities are doing to regenerate the sons of Africa.

Camp Saxton.

In our paper of Jan. 24 we gave an interesting picture of the festivities of the colored race on New Year’s Day. These were held at Camp Saxton, known formerly as Smith’s Plantation. It is the new headquarters of the 1st Carolina Colored Volunteers, commanded by Col. Higginson, who devotes every energy to overcome that natural love of idleness inherent to all inferior or oppressed races. The camp is well arranged, and the men present as soldierly an appearance as negroes seem to be capable of. Still they do not come up to anything like what the French Turcos are, not yet up to the black regiments of the British West India-Islands.

New South Village, or Mitchelville.

When Gen. Mitchel resolved to try the effect of voluntary labor, he made arrangements for the building of a number of little cottages for the colored people, and it was named after him. It is situated on Hilton Head Island, and presents ever evening scenes of remarkable gaiety.
