PORTSEA, a parish, divided into the liberty part, which is within the jurisdiction of the borough of PORTSMOUTH, and the Guildable part, which is in the hundred of PORTSDOWN, Portsdown division of the county of SOUTHAMPTON, 17 miles (S. E.byE.) from Southampton, and 7l (S. W.) from London, and containing 38,379 inhabitants. This place, which is now the principal naval arsenal of Great Britain, takes its name from the island of Portsea, to which, on the retiring of the sea from the ancient Portchester, the inhabitants removed, and at the mouth of the harbotir built the town of Portsmouth, to which it was originally a small suburb. The island is nearly sixteen miles in circumference, and is bounded on the south by Spithead, on the east by Langston harbour, on the west by Portsmouth harbour, and on the north by a channel uniting them, over which is a bridge, connecting it with the main land. It abounds with a great variety of animal and vegetable productions, but has nothing peculiar in its geological formation. Widgeons, wild ducks, teal, and curlew, are found in abundance; larks congregate in numerous flocks, and the snow-bunting, the cross-bill, and other scarce birds, are occasionally seen. More than two hundred different species of insects have been collected in the course of one summer, and a great variety of shells is found on the beach. The town, which is situated on the waste ground formerly called Portsmouth common, has rapidly increased within the last century, and its population is at present more than five times as great as that of Portsmouth, though the houses were originally permitted to be built on condition of their demolition in the event of an enemy landing. It contains many good and regularly-formed streets, several terraces, crescents, and handsome ranges of respectable houses, inhabited by the more opulent families connected with Portsmouth, and has very extensive suburbs, chiefly inhabited by artizans employed in the dock yards; it is well paved, lighted with gas, by a company incorporated by act of parliament in 1821, and amply supplied with water by the Portsea Island water-works. The Hampshire subscription library is well supported,'and contains a valuable collection of volumes in the various departments of literature. The fortifications, which were begun in 1770, are very complete, and are unrivalled for strength and beauty: the lines extend from north to south, presenting to the eastward several strong bastions and outworks, crowned with batteries of heavy ordnance; and the trenches, which are broad and deep, can be instantaneously filled with water up to the bridges, which connect it with Portsmouth, on the south. The Royal Dock-yard occupies an area of one hundred and fen acres, and comprises, on the grandest scale, and on the most scientific principles, the numerous arrangements for supplying the necessary equipments, and extensive dep6ts of naval and military stores. The entrance into the yard, which forms a town of itself, is through a lofty handsome gateway; and among the numerous buildings within the walls, the residence of the commissioner is conspicuous for its stateliness; in the centre of the building is a noble portico, and on each side are the various offices connected with the establishment. The great basin comprehends an area of thirty-three thousand square yards, communicating with four dry docks; and there is also a double dock for frigates. Ships of the line may at any time enter from the harbour into the dock-yard, where twelve men of war can be fitted uji at the same time. The covered building-docks are very capacious; the rope house is of vast extent, being one thousand and ninety-four yards long, and four stories high; on the lower, story, the floor of which is laid with iron and tin, is the immense machinery for making cables, of which some are thirty inches in circumference; the three upper stories are appropriated to the manufacture of twine and cordage. The anchor forge is an immense building, in which anchors weighing more than ninety hundred weight are made for the navy. Near the forge are the copperfoundry, and the admirable machinery for making blocks, invented by Mr. Brunei, who for many years superintended its operation: it is impelled by a steam-engine of extraordinary power, and the various processes, from the sawing of the wood to the completion of the block, are conducted by the aid of machinery alone, with a degree of precision and celerity difficult to describe. The rigging and the mast houses are upon the largest scale; and every department in this extensive and ably-conducted establishment exhibits a combination of skill, efficiency, and grandeur, in every respect characteristic of the arsenal of a great maritime state. The Dock chapel, appropriated to the officers of the dock-yard, the crews of the ships in ordinary, and the various classes of artizans, is a neat modern structure, with a cupola, in which hangs the bell originally belonging to the Royal George, which was sunk off Spithead. The principal officers are, a commissioner, clerk of the checque, storekeeper, master-wright, chaplain, surgeon, and purveyor. During the war, nearly four thousand men were employed. Within the walls are the Royal Naval College, founded, in 1720, for one hundred students in time of war, and for seventy during peace; of these, thirty, the sons of commissioned naval officers, pay £ 60 per annum, for board, clothing, and education; and the remainder, sons of noblemen, military, or civil officers, pay £ 100 per annum; the term of continuance in the college is two years, and no one can remain in it more than three, at the end of which, if qualified, the students are appointed midshipmen in the navy, from which if they retire before the expiration of the term requisite for obtaining a lieutenancy, a fine of £200 is imposed on those of the first class, and of £100 on those of the second. This institution is under the superintendence of a governor, who is first lord of the Admiralty, a lieutenant-governor, a post-captain, and professor,' each of whom has a salary of £800 per annum, with apartments; four lieutenants, who have each £250 per annum, with board and lodging; a mathematical assistant, with a salary of £250; two other assistants, with £200 per annum, who have apartments rent-free; and French, drawing, and fencing masters, who have each a salary of £100 per annum. The buildings are extensive, and contain many noble apartments; over them is an Observatory, in which is a beautiful model of H. M. S. the Victory, of one hundred guns, which was wrecked off the French coast on her first voyage: a new Observatory has been recently erected-over the central arch of the western storehouses, commanding a view of the whole coast, from the Needles to the coast of Sussex. A school of naval architecture was projected, in 1809, by Mr. Robinson, in the House of Commons, and, in 1816, incorporated with the Naval College, in which provision is made for the maintenance and education of twenty-four shipwrights apprentices, who are required, previously to their admission, to write English grammatically, to speak French, and to be acquainted with the first six, and the eleventh and twelfth, books of Euclid, and with quadratic equations in Algebra. Their admission is dependent on examination before the commissioners, the professor, and the lieutenant-governor; they remain for seven years in the establishment, and, at the expiration of that term, they arej appointed to some situation in the Royal Dock-yard: during their apprenticeship they are under the superintendence of a professional shipwright, and receive an annual salary, which increases gradually from £25 to £60. The Gun wharf, without the dock-yard, includes an area of fourteen acres, and consists of a spacious building of brick, ornamented with stone, occupying three sides of a quadrangle, with an arched entrance in the centre of the fourth side, surmounted by a lofty tower and cupola; it contains a vast number of guns and gun-carriages, and an immense quantity of ordnance stores; on the right of the entrance is the armoury, containing twenty-five thousand stand of small arms, arranged in the most exact order, a laboratory, and an extensive ordnance department, with residences for the principal officers; on the opposite side are the offices of the Royal Engineers, with stores adjoining, and a large dep6t of ammunition. The dock-yard has suffered from several destructive fires, the last of which occurred in 1776; the incendiary, John Aitkin, more commonly known as Jack the Painter, was gibbeted on Block House heath. No other trade is carried on except what arises from, or is connected with, the dock-yard. In that part of the parish called the Guildable is a considerable number of market gardens, from which the towns of Portsea and Portsmouth are principally supplied with vegetables. The Portsmouth and Arun canal passes through the town: it was opened in 1823, and joins Langston harbour, across which barges are towed by steam-boats constructed for the purpose. The market days are Tuesday, Thursday, and Saturday. That part of the parish which is not within the limits of the borough of Portsmouth, is within the jurisdiction of the county magistrates. The living is a vicarage, in the archdeaconry and diocese of Winchester, rated in the king's books at £12, and in the patronage of the Warden and Fellows of Winchester College. The church, dedicated to St. Mary, was erected in the reign of Edward III., and is surrounded by one of the largest cemeteries in the kingdom. St. George's church, a commodious brick structure, was erected for the additional accommodation of the increasing population in 1753; the living is a perpetual curacy, endowed with £ 200 private benefaction, and £900 parliamentary grant, and in the patronage of the Vicar of Portsea. St. John's church, a neat commodious edifice, of which the internal decorations are extremely rich, was consecrated in 1789: the living is a perpetual curacy, endowed with £ 800 parliamentary grant, and in the patronage of the Vicar. The church dedicated to St. Paul, in the suburb of Southsea, was erected in 1822, at an expense of £15,229. 18. 8., of which £600 was raised by subscription, and the rest by grant from the parliamentary commissioners; it is a handsome structure in the later style of English architecture, with four turrets at the angles, and contains one thousand eight hundred and twenty-one sittings, of which nine hundred and three are free; the living is a perpetual curacy, in the patronage of the Vicar. In this suburb is an excellent bathing establishment, which has contributed greatly to the attractions of Portsea, as a watering-place. The church dedicated to All Saints, in the suburb of Mile- End (including the Half-Way houses, Newtown, and several spacious streets, forming an extensive district, now called Southport), was erected, in 1827, by grant from the parliamentary commissioners, at an expense of £12,064, it is an elegant edifice, in the later style of English architecture, with a splendid western front, surmounted by a campanile turret, and contains one thousand seven hundred and thirty-nine sittings, of which one thousand one hundred and six are free; the interior is neatly arranged, and over the altar is a window of beautiful design. In Portsea and its suburbs are six places of worship for Baptists, and one each for Independents and Wesleyan Methodists. St. Paxil's school, a commodious building, near the church of that name, has been recently established by one hundred subscribers, for the education of their children. The National school, in which two hundred children are educated, is supported partly by subscription, and with funds arising from various benefactions. Mr. Edward Crafts bequeathed a house and premises, in 1780, which produced £28 per annum,- Mr. Richard Wilmot, in 1805, bequeathed £500; and Major Ebenezer Vavasour, in 1808, left £100, towards the support of this institution. A dispensary, .and an. infirmary for diseases of the eye, are supported by subscription. Thomas Fitzherbert, Esq., in 1821, left £ 10,000 in the four per cents., in trust to the vicar and ministers of the chapels, for the maintenance of five aged men, ten aged widows, and five single women, of this parish: there are also various charitable bequests for distribution among the poor. The eastern part of the island, not included in the boundaries of Portsmouth and Portsea, is extra-parochial, and belongs chiefly to government; in this part are numerous salt-works.
