TRTNG, a market-town and parish in the hundred of DACORUM, county of HERTFORD, 30 miles (W. by N.) from Hertford, and 31 (N.Wby W.) from London, containing, with the hamlets of Long Marstone and Wilstone, according to the last census, 3286 inhabitants, now about 4000. The origin of this town is of remote antiquity: at the time of the division of the county by Alfred, it was considered of sufficient importance to give name to the hundred in which it was situated, being then called Treung. Antiquaries have attributed the derivation of its name to the supposed original form of the town, being triangular. The opinion that it is of Roman origin receives confirmation from the fact, that the Iknield way from Dorchester to Colchester passed in its vicinity; part of it constitutes a portion of the Chiltern hundreds. The town consists of two principal streets, the larger being crossed at the top by the other, both containing good houses, generally of modern style. Contiguous to it is the elegant mansion of Tring Park (built by Charles II., for his favourite mistress, Eleanor Gwynn, and since modernised), with the hills rising in the back ground, clothed with fine beech trees. The general appearance is exceedingly neat, the atmosphere very salubrious, and the inhabitants are amply supplied with water. A silk-mil], worked partly by water and partly by steam, gives employment to upwards of three hundred persons, and is in progress of great improvement: the manufacture of canvas and straw-plat is also carried on. The Grand Junction canal passes about a mile of the town; and within the parish are four large reservoirs, to supply any loss of water to that navigation. At Wilstone, also within the parish, is one of the sources of the river Thames. The market, granted by charter of Charles II; to Henry Guy, Esq., in 1681 (to whom that monarch had, the year before, granted the manor), is on Friday, for straw-plat, corn, meat, and pedlary; and cattle fairs are held on Easter-Monday and Old Michaelmas-day. The market-house, the property of the lord of the manor, is situated on the north side of the principal street. The living is a perpetual curacy, in the archdeaconry of Huntingdon, and diocese of Lincoln, endowed with £1200 private benefaction, £400 royal bounty, and £2000 parliamentary grant, and in the patronage of the Dean and Canons of Christ Church, Oxford. The church, which is dedicated to St. Peter and St. Paul, situated near the market-house, is a handsome embattled structure in the ancient English style, with a large tower at the west end, surmounted with a low spire; in the interior is an enriched font in the later style of English architecture. There are places of worship for Baptists and Independents. A free school was established, in 1829, by Mr. John Hull; it is conducted on the Lancasterian system, and supported by voluntary contributions; nearly one hundred boys are instructed. A Roman helmet was found in digging the Grand Junction canal, near Northcote hill, between this town and Berkhampstead, of which a drawing was published by the Society of Antiquaries of London, in 1819. Robert Hill, a remarkable self-taught linguist, was born here, in 1699; he died in 1777.
