When the Second Regiment entered it, it was little more than an outline.

Its shape was described upon the sand, and the palmetto rafts lay around it, waiting to be moulded into form.

The structure was an inartificial one--a simple wall, behind which young beginners might train guns to do mischief to a veteran enemy in front.

Its form was square, with a bastion at each angle, sufficiently large, when finished, to cover a thousand men.

It was built of logs, laid one upon another in parallel rows, at a distance of sixteen feet, bound together at frequent intervals with timber, dovetailed and bolted into the logs.
