Leaving the Hotel by a pathway to the west, the visitor is conducted to the siege battery of rifled guns, exhibiting the form and structure of a field work, and from thence to a grove of elms, where a variety of trophy guns are to be seen, taken during the Revolution, in the war of 1812, in Mexico, and in the late rebellion. A portion of the great chain surrounds the beautiful gun "Le Monarque," presented by Congress to Lafayette, and one or two mortars captured by General Wayne at Stony Point. Beside the antique mortars and guns from Mexico, inscribed with the names of the places from which they came, there are two English rifled Blakely guns, from Fort Pulaski, two carronades, or ship's pivot guns, from Hilton Head, one 8-inch rifled Blakely, from Fort Morgan, all captured from the rebels; and the fragments of Gen. Gilmore's famous 30-pound Parrott gun, from Morris Island, which hurled 4,606 projectiles at Charleston before it assumed its present condition. These trophies, scarred and bruised by shot, and many other large guns made for experimental purposes, cannot fail to afford an interesting subject for contemplation. The large granite ball was brought by Gen. Delafield from the Crimea, where it is said such projectiles were thrown from mortars by the Russians, to crush the decks of the blockading fleet. The spot is further interesting from its having been dedicated as the site of the proposed Battle Monument, designed to be erected by subscription among the surviving officers and soldiers, to the memory of the officers of the regular army who fell during the rebellion. A little to the westward, a walled enclosure, embracing the Ordnance Laboratory, is situated, and there may be seen a great variety of trophy guns from Cedar Creek and from Vicksburg, among which is the famous "Whistling Dick," an English rifled breech-loading Whitworth gun, captured on Morris Island, and the formidable Armstrong gun, captured at Fort Fisher, off Wilmington. Here, also, may be seen the gun from Elder's Battery, which fired the last shot previous to the surrender of Lee's Army. These, and a great variety of torpedoes, shot, shells and other Rebel implements of warfare, will well repay the visitor by the variety of design they exhibit. Pursuing the road down the hill, to the North wharf, the Sea-coast battery, with its armament of rifled monsters, consisting of 30-pound, 100, 200, and 300-pound Parrots, the 15-inch gun, and the 13-inch mortar, all capable of hurling projectiles as far as Pollopel's Island, or beyond, arrests the attention of the observer, and furnishes tangible evidences of the triumphant progress of manufacturing skill in weapons of war.
