HORNCASTLE, a market-town and parish in the soke of HORNCASTLE, parts of LINDSEY, county of LINCOLN, 21 miles (E.) from Lincoln, and 134 (N.) from London, containing 3058 inhabitants. From its situation, and the circumstance of a very extensive castle having been erected here (a portion of the remains of which is still visible,) this place has, with great probability, been considered the Bannovallum of the Romans, mentioned by the geographer of Ravenna. Its present name is evidently a corruption of Hyrncastre, as it was denominated by the Saxons, from hyrn, an angle, or corner (the town being situated within an angle formed by the confluence of the rivers Bane and Waring), and castrum, a fort, or castle. The vallum, or fortification constructed by the Romans having been considerably strengthened by Horsa, soon after the arrival of- the two Saxon brothers, was afterwards demolished by Vortimer, the brave king of the Britons, and the castle was taken and destroyed, after a victory obtained by one of his generals over the Saxon prince, at the neighbouring village of Tetford. At the period of-the Norman survey, the manor and. soke (the latter comprising, besides the town, the parishes of West Ashby, Coningsby, Haltham, Langrick Ville, Mare- ham le Fen, Mareham on the Hill, Moorby, Roughton, Thimbleby, Thornton le Fen, High Toynton, Low Toynton, Wilksby, and Wood-Enderby,) belonged to the king,, previously to which they had formed part of the possessions of Editha, Queen of Edward the Confessor. It does not appear at what time the manor first came into private hands, but, after various grants and reversions, it was sold, in the reign of Henry III., to Walter Mauclerlce, Bishop of Carlisle 5 to whom that monarch granted three charters, conferring various immunities on the inhabitants of the town and soke, whereby Horncastle, from an insignificant village, became the general mart for the surrounding district: -with the exception of a short interval during the reign of Edward VI., it has continued to belong to that see ever since. The town, which is neat and well built, occupies a low but pleasant situation at the foot of the Wolds. From a plan made by Dr. Stukeley, in 1722, it appears to have been scarcely half so large as it is at present; and the houses, then built with clay-walls, and covered with thatch, have been succeeded by respectable brick edifices; the general appearance of the neighbourhood has also been greatly improved by the enclosure of lands, under the authority of an act obtained in 1803. Here is a subscription library, formed in 1790, and containing about one thousand volumes; and the-clerical library, in High-street, comprises some respectable standard works. Formerly, many of the inhabitants were employed in tanning leather, but about fifty years ago this branch of trade here experienced a rapid decline, so that there are now but two tan-yards remaining. The prosperity of the town has been in a great degree advanced by an act obtained in 1792, under the powers of which a canal was constructed, communicating with the river Bane, which was thus madenavigable to the Witham; and by this means a junction has been formed with the Trent and its numerous ramifications. Since the completion of this undertaking, in 1801, considerable commerce has been carried on in corn and wool, about thirty thousand quarters of the former, and three thousand packs of the latter, having been annually sent from this place to different parts of England. The market is on Saturday; and the fairs are, one concluding on the 22nd of June, which is chartered for eight days, but seldom lasts more than three; the second terminates on the 21st of August, after having continued about ten days, although the charter limits its duration to seven: it is the largest fair for horses in the kingdom, many thousands being exhibited for sale during its continuance, and it is resorted to by dealers from all parts of the country, from the continent, and from America. The third fair, held on the 28th and 29th of October, was removed hither from Market- Stainton, in 1768, for a consideration of £200 paid to the lord of that manor. In the 47th of George III., an act was passed for establishing a court of requests for the recovery of debts under five pounds, which is held here every fourth Thursday, its jurisdiction extending over "the sokes of Bolingbroke and Horncastle, and the wapentake of Candleshoe, (except the parishes of Hagnaby, Welton in the Marsh, Steeping-Magna, and Firsby,) jn the county of Lincoln, and for the wapentakes of Gartree, Louth-Eske, Ludborough, Calceworth, Hill, and Walshcroft, the north and south divisions of the wapentake of Yarborough, such parts of the wapentake of Manley as lie east of the river Trent, and the parishes of Faldingwbrth, Buslingthorpe, Snarford, Friesthorpe, and Hanworth." The charter granted by Henry III. to the bishop, as lord of the manor, gave authority to try felons and to hold a court leet, and exempted the inhabitants from toll and several other payments and services, besides protecting them from arrest by the officers of the king or the sheriff. On the eastern boundary of the parish is a spot called Hangman's Corner, where criminals capitally convicted in the court of the manor were executed; but these manorial rights and privileges, except the court leet, have been long disused. The living is a vicarage, in the archdeaconry and diocese of Lincoln, rated in the king's books at £ 14. 4. 2., and in the patronage of the Bishop of Carlisle. The church, dedicated to St. Mary, appears, from the few remaining portions of the original edifice, to have been erected about the time of Henry VII.: it comprises a north and a south aisle, continued on each side of the chancel: the aisle north of the chancel was rebuilt in 1820, and part of the aisle south of the nave, in 1821; the interior is exceedingly neat, and there are several interesting monuments to different members of the family of Dymoke, of Scrivelsby, holding the office of hereditary champion of England, Baptists, Independents, and Primitive and Wesleyan- Methodists, have each a place of worship. The free grammar school was founded by Edward, Lord Clinton and Saye, Lord High Admiral of England, by virtue of letters patent granted in 1.562; its endowment consists of houses and land at Horncastle, Hemingby, Sutton, Huttoft, and Winthorpe, the average rental of which is about £200 per annum; £80 per annum is paid to a master and £30 to an usher; in addition to this, each boy pays two guineas a year for instruction in writing and arithmetic. The management of the affairs of this school is entrusted to ten individuals, who are a body corporate, possessing a. common seal. They are also trustees of another charity school, founded by Mr. Richard Watson, in 1734, wherein poor children are instructed to read, sew, and knit, by a teacher whose stipend is £ 17 per annum, with a residence rent-free. A National school for boys and girls, and a school on the Lancasterian plan, are supported by subscription and afford the means of education to about four hundred children. A general dispensary, was opened in 1789. The poor in general derive considerable assistance from numerous benefactions recorded on a mural tablet in the church. The remains of the ancient fortress of Horncastle merely serve to exhibit its form and magnitude: it appears to have enclosed an area of about six hundred feet in length, and in breadth three hundred and fifty, on the east, and three hundred on the west.. A little south-westward from the town, near the union of the rivers, was one of those Roman labyrinths called the Julian bower. Many urns, coins, fibula, and other vestiges of that people, have been discovered at different periods..
