STAINES, a market-town and parish, in the hundred of SPELTHORNE, county of MIDDLESEX, 10 miles (W. S.W.) from Brentford, and 17 (W. S. W.) from London, containing 1957 inhabitants. This place has by some been conjectured to derive its name from a Roman milliarium, which is stated to have been placed here, and the traces of a Roman road pointing towards Staines' bridge, mentioned by Dr. Stukeley, who also states the town to have been surrounded by a ditch, may in some degree strengthen this conjecture; but the more general opinion is, that its name is owing to a stone which, standing on the banks of the river near it, marks the extent of the jurisdiction of the Lord Mayor of London, as conservator of the Thames; the inscription on it bears date 1284. An army of Danes, on their way from Oxford (which they had burned) to their ships, crossed the river here, in 1009, on hearing that an army was marching from London to oppose them. The town, which has been much improved of late years, consists principally of one wide street, containing some good houses, terminating at the river Thames, across which is an iron bridge of one arch. In lieu of this, which has been considered unsafe, a handsome stone bridge has been erected, and a new street formed in a line with it, which will avoid the sharp turn over the former, where many accidents have occurred. The market is on Friday: the market-house, standing near the bridge, is a small building surmounted by a spire. There are fairs on May llth and September 19th. The living is a vicarage, with the perpetual curacies of Ashford and Laleham annexed, in the archdeaconry of Middlesex, and diocese of London, rated in the king's books at £ 12. 3. 4., and in the patronage, of the Crown. The church, dedicated to St. Mary, erected in 1631, by Inigo Jones, has been recently rebuilt; it is a neat structure, with a square embattled tower; the interior, which is well arranged and handsomely fitted up, contains three hundred and forty-four free sittings, towards defraying the expense of which, the Incorporated Society for the building and enlargement of churches and chapels granted the sum of £250. There are places of worship for Baptists, the Society of Friends, and Independents. Here are a National and a Lancasterian school for boys, and a National school and a school of Industry for girls. Duncroft House, in which King John is said to have slept, the night after he signed Magna Charta at Runymede, is in this parish. A forest anciently extended from Staines to Hounslow, but part of it, consisting of about three hundred acres, has been enclosed.
