NEWMARKET, a market-town, comprising the parish of St-Mary, in the hundred of LACKFORD, county of SUFFOLK, and the parish of All Saints, in the hundred of CHEVELEY, county of CAMBRIDGE, 13 miles (N.E. by E.) from Cambridge, and 61 (N.N.E.) from London, on the road to Norwich, containing 2514 inhabitants. The earliest account of this town has reference to the year 1227, when it is supposed to have derived its name from a market then recently established, which is said to have been removed hither, on account of the plague raging at Exning, a village about two miles dis- tant, where was, probably, the parochial church; and in the time of Edward III. it gave name to Thomas Merks, or de Novo Mercatu, Bishop of Carlisle, who was probably a native of the place. A house, called the King's house, was originally built here by James I., for the purpose of enjoying the diversion of hunting, and the subsequent reputation of -this town for horse-racing seems to have arisen from the spirit and swiftness. of some Spanish horses, which having been wrecked with the vessels of the Armada, were thrown ashore on the coast of Galloway and brought hither. Its celebrity greatly increased in the reign of Charles II., the grand patron of the turf, who rebuilt the King's house, which had fallen into decay during the civil war, and frequently honoured the races with his presence. On the 22nd of March, 1683, being the time of the races, the King, -Queen, and Duke of York were present, but a sudden conflagration compelled them to return hastily to London, to which event some writers have attributed the defeat of the Rye-house plot: by this disaster a great part of the town was destroyed, and the damage was estimated at £20,000. A second conflagration happened about the beginning of the last century. At the close of the civil war, Charles I. was removed from the house of Lady Cutts, of Childerley, to Newmarket, on the 9th of June, 1647, and remained here about ten days. The town consists principally of one street, the north side of which is in the county of Suffolk, and the south in that of Cambridge; it is neither lighted nor paved; the houses are modern and well built, and some, erected for the occasional residence of visitors, are handsome: the inhabitants are supplied with water from springs. Coffee-houses, billiard-rooms, and others, furnish appropriate accommodation for all meetings, preliminary to the races. The race-course and training-grounds are the finest in the kingdom; the former is on a grassy heath hear the town, and in the county of Cambridge, extending in length four miles; the training-ground is more than a mile and a half long, on a very gentle acclivity, admirably adapted to keep the horses in wind. The races are held seven times in the year, and are, distinguished as the Craven meeting, commencing on the Monday in Easter week; the first and second spring meetings, the former on the Monday fortnight following, and the latter a fortnight afterwards; the July meeting j the first and second October meetings, and the third October, or Houghton meeting, the first of these commencing on the Monday preceding the first Thursday in that month; the king gives two plates annually. The palace erected by King James has been- sold, and converted into shops the one added to the original structure by King Charles is standing, and was the residence of the late Duke of York during the meetings; belonging to it are extensive stables for the king's horses. The training of race-horses is a source of extensive profit, several of them, among which are some of the finest horses in the world, being constantly exported, at exceedingly high prices; about four hundred are here during the greater part of the year; and it is computed, that the weekly consumption of oats in the town alone, amounts to the amazing quantity of five hundred quarters. The market, which was granted or confirmed in 1227, is held on Tuesday; and there are fairs on Whit- Tuesday and November 8th, the latter being extensively supplied with cattle, horses, corn, butter, cheese, hops, &c. The county magistrates hold petty sessions here every Tuesday 5 and a court leet is held occasionally. The parishes of St. Mary and All Saints are in the archdeaconry of Sudbury, and diocese of Norwich$ the former is a discharged rectory, consolidated with the vicarage of Wood-Ditton, rated in the king's books at £4.15. 2., and in the patronage of the Duke of Rutland; the church is a handsome structure with a fine tower and spire. The latter is a perpetual curacy, endowed with £400 royal bounty, and in the patronage of the Bishop of Norwich. There is a place of worship for Independents. Free schools are supported by a donation of £50 per annum from Queen Anne, which is equally divided, after the deduction of fees of the Exchequer, between the master and the mistress, for which they are required to teach twenty-one boys and twenty* one girls: a National school haying been recently estaN Wished, the twenty-one boys on Queen Annes foundation are instructed there as free scholars; the remainder, being about one hundred and ten, are paid for by the subscribers; the girls, instructed by the schoolmistress, are provided with cloaks and bonnets. About a mile. and a half from the town is a rer markable'excavation, called the "Devil's Dyke, extending nearly in a straight line for. seven miles, and being in some places above one hundred feet in width: this work, unquestionably of very remote antiquity, has been attributed to the Britons anterior to the time of Caesar, and by some to Uffa, the first king of the East Angles; but, notwithstanding that much pains have been taken in the research, no authentic account has ever yet appeared of this remarkable monument of human industry and perseverance; it serves for the boundary between the dioceses of Norwich and Ely. Several Roman coins were found near Newmarket heath, in the year 1750.
