I could now readily understand the Rebel boast, that Fort Sumter, after each attack upon it, was stronger than ever. Stronger for defence, as far as its walls were concerned, it undoubtedly was; but where were the double rows of portholes for heavy ordnance, and the additional loopholes on the south side for musketry? Our guns had faithfully smashed everything of that kind within their range.

On the northwest side, facing the city, the perpendicular lofty wall stands in nearly its original condition, its scientific proportions, of stupendous solid masonry, astonishing us by their contrast with the other sides. Between this wall and the wreck of a Rebel steamer, shot through and sunk whilst bringing supplies to the fort, we landed. By flights of wooden steps we reached the summit, and looked down into the huge crater within. This is a sort of irregular amphitheatre, with sloping banks of gabions and rubbish on all sides save one. On the southeast side, where the exterior of the fort received the greatest damage from the guns on Morris Island, the interior received the least. There are no casemates left, except on that side. In the centre stands the flag-staff, bearing aloft the starry symbol of the national power, once humbled here, and afterwards trailed long through bloody dust, to float again higher and haughtier than ever, on those rebellious shores. Who, that loves his country, can look upon it there without a thrill?

The fort is built upon a mole, which is flooded by high-water. It was half-tide that morning, and climbing down the slope of the southeast embankment, I walked upon the beach below,—or rather upon the litter of old iron that strewed it thick as pebble-stones. It was difficult to step without placing the foot upon a rusty cannon-ball or the fragment of a shell. The curling waves broke upon beds of these iron debris, extending far down out of sight into the sea. I suggested to an officer that this would be a valuable mine to work, and was told that the right to collect the old iron around the fort had already been sold to a speculator for thirty thousand dollars.

The following statement of the cost to the United States of some of the forts seized by the Rebels, and of others they would have been glad to seize, but could not see their way clear to do so, will interest a few readers.

Fort Moultrie, $87,601. (Evacuated by Major Anderson Dec. 26th, 1860.)

Castle Pinckney, $53,809. (Seized by South Carolina State troops, Dec. 27th, 1860.)

Fort Sumter, $977,404.

Fort Pulaski, at the mouth of the Savannah River, $988,859. (Seized by order of Governor Brown, Jan. 3d, 1861.)

Fort Morgan, Mobile Harbor, $1,242,552. (Seized Jan. 4th, 1861.)

Fort Gaines, opposite, $221,500. (Same fate.)
