Here, too, were half a dozen temporary wooden structures, used as shops and storehouses, and all manner of rubbish: piles of brick, stone flagging, sand, and high mounds of oyster shells. When burned, the shells produced lime for cement. The fort’s wharf and esplanade, which surrounded its exterior walls, were piled with flagstone, sand, and twenty thousand bricks. The disarray made communication within the fort difficult, though it is likely the garrison’s twenty-five children found ways to use it all profitably.
