SHEERNESS, a sea-port and market-town and chapelry, in the parish of MINSTER, having separate jurisdiction, though locally in the liberty of Isle-of-Sheppy, lathe of SCRAY, county of KENT, 21 miles (N. E.) from Maidstone, and 50 (E. by S.) from London, containing 817 inhabitants. This place, which is situated at the northwestern point of the Isle of Sheppy, on the river Medway, at its junction with the Thames, was a mere swamp until the. reign of Charles II., when the importance of its situation being appreciated, that monarch, early in 1667, directed the construction of a strong fort, and twice personally ascertained its progress. In the same year, before the new fortifications were in a very advanced state, the Dutch fleet entered the Thames, and made their memorable attack on the shipping in the- Medway, having in their passage destroyed that portion of the works which was completed, and landed some men, who took possession of the fort. In consequence of this, a regular fortification, with a line, of heavy artillery and of smaller forts higher up, on each side of the Medway, was formed, to which other works have since been added. A garrison is kept up, under the command of a governor, lieutenant-governor, fort-major, and inferior officers; and the construction of a royal dock-yard, for repairing ships and building frigates and smaller vessels, has caused Sheerness to become a naval station of the first importance. In 1798, the mutiny of the fleet stationed at the Nore threatened this town with the most alarming consequences, arid induced many of the inhabitants to make a precipitate retreat to Chatham and other places; but the fortunate suppression of this formidable insurrection saved the town from the apprehended danger. In 1827, it suffered from a dreadful fire, which destroyed fifty houses, and property of the value of £60,000; but the houses, which were before principally of wood, have been replaced by others built of brick. Owing to the naval establishment formed here, Sheerness has grown up into a considerable town, consisting of two divisions, Blue Town and Mile Town: it has been recently much enlarged, some new streets and a spacious hotel having been erected, the latter fitted up in a very superior style; but there are not sufficient houses for the population, many of the poorer inhabitants residing in the hulls of old vessels, though, in consequence of recent reductions in the dock-yards and arsenals, the number has considerably decreased. A pier and causeway extend from the town to low water mark, which are kept in good repair; and the town is paved, lighted, and cleansed under the authority of two acts of parliament passed in the 41st and 49th of George III. There was formerly a great scarcity of water, but it is now supplied, and of a very excellent quality, at one half-penny per pail, from four subscription wells, which have been sunk to a depth of three hundred and sixty feet: the principal one, called King's well, is within the fort, and supplies the vessels at the Nore. This place has latterly become the resort of a great deal of company, attracted by the facility of seabathing the beach, on which the machines are stationed, being very clean, and forming a delightful promenade. On the cliffs leading from the beach towards Minster there is, perhaps, one of the most splendid and interesting views in the- kingdom; the German Ocean on the east; the rivers Thames and Medway, bearing innumerable vessels of all sizes, with the town and harbour of Sheerness, to the north and west j and the fertile valleys of Kent, with the Medway winding through them, and the towns and villages interspersed, towards the south, combine in presenting a diversity and sublimity of landscape rarely excelled. The harbour has of late years been much enlarged and improved, and is now safe and commodious, often presenting a splendid appearance from the number of vessels in it; passage boats ply with every tide, and a steam-boat daily, to and from Chatham, and there is in summer a regular communication by steam-boats with London. The dock-yard has been greatly extended and improved within the last fifteen years, at a cost of about three millions, ancj is now one of the finest in Europe; it covers an area of sixty acres, and is surrounded by an extremely well built brick wall, which cost £40,000. The docks are sufficiently capacious to receive men of war of the first class, with all their guns, stores, equipments, &c., on board j and two steam-engines, each of fifty horse power, have been erected for the purpose of pumping them dry. There is a basin, with a depth of water of twenty-six feet, which will hold six ships of the first class; and two of a smaller size, for storeships and boats. The storehouse, which is the largest building in the country, is six stories high, with iron, joists, beams, window-frames, and doors, and will contain at least thirty thousand tons of naval stores; there are also a handsome victualling storehouse, smithy, navy pay office, mast-houses, &c. The commissioners and principal officers of the establishment have handsome houses in the yard, and a noble residence has been, erected in the garrison for the port-admiral, in which are state rooms for the reception of the royal family, the lords of the admiralty, &c. The principal establishment of the ordnance departments has been removed, hence to Chatham, where the stores for the fleet at. the, Nore, &c., are kept, and the ground formerly occupied by it has been added to the dock-yard. An office connected with this department is still, however, retained, here; and it is said that government contemplates the re-establishment of the department at this place on a very enlarged scale, and the extension of the present line of fortifications from the garrison point, outside the town, to the sea wall, called Queenborough wall, for which purpose they have purchased two hundred acres of land surrounding the town. The principal government officers residing here are clerks of the cheque and survey, store-keeper, master shipwright and his assistant, master attendant, master caulker, boatswain, surgeon, and porter. Many convicts are employed in the hulks and in the improvements here. The chief trade in the town arises from the dockyard and other establishments connected with government, though considerable quantities of corn and Seed, the produce of the isle, as well as oysters (of which the beds extend all aleng the coast, as far as Milton), are shipped for the London market. There are copperas works of considerable extent, within a few miles of the town; the pyrites, or copperas stones, are collected in heaps upon the beach, from the falling cliffs, and carried away in vessels. The market is on Saturday, but there is no regular market-place. The parish church was formerly at Minster, about four miles distant, but a very elegant church has lately been erected at the east end, but outside the wall, of the dock-yard, the area of which is appropriated for the officers, &c.,' of the dock-yard, and the galleries for the public. The chaplain is appointed by the Board of Admiralty. The living is distinct from that of Minster, though it is in contemplation to unite them, and the ecclesiastical government is in the jurisdiction of the Consistorial Court of Canterbury, concurrently with the Archidiaconal court. There are two places of worship each for the Baptists and Independents, and one each for the Primitive and Wesleyan Methodists, the Unitarians, and Roman Catholics, also a Synagogue. Sunday schools are attached to the chapels of the Baptists, Independents, and Wesleyan Methodists, in which more than one thousand children are instructed; there are several reading societies. In sinking the wells here, the workmen, at the depth of two hundred feet, discovered a complete prostrate forest, through which, in the prosecution of their work, they were obliged to burn their way; which is considered to be a remarkable confirmation of the history of the deluge, and specimens are in the possession of most of the Philosophical Institutions in Europe. Stones well adapted for the composition of Roman cement, in consequence of being impregnated with copperas, are dredged up from the sea in the neighbourhood of the cliffs.
