OATHLAW, or Finhaven, a parish, in the county of Forfar, 5 miles (N. by E.) from Forfar; containing 420 inhabitants. The original name of this parish appears from ancient documents to have been Fyniven or Finavon, now corrupted into Finhaven; but no precise account can be given of the time or cause of its change to Oathlaw. It is supposed, however, upon the authority of an old record, that a chapel formerly stood upon some property called Oathlaw, and that, when the ancient church of Finavon fell to decay, this chapel, being used as the church, gave the name of the estate on which it was situated to the whole parish. The appellation Finavon is compounded of two Gaelic words. Fin, signifying " white or clear", and Avon or Aven, signifying " a water or a river". The parish seems in early times to have been the theatre of extensive and important mihtary operations. Upon the beautiful hill of Finhaven, which rises to , a considerable height above the level of the surrounding country, is a celebrated vitrified fort, in the shape of a parallelogram, extending about 476 feet from east to west. It is a very strong work, and is supposed to have been the head post of some warlike chief, with his several native tribes, and designed to command the passes in this part of the country. Another supposition is, that it was a temple erected to the god of fire, worshipped by the Druids; there are remnants of smaller temples all over the country, and this great temple seems to have commanded a view of many of them. On the low grounds, about two miles and a half to the north-west, are the remains of an extensive Roman camp called Battledykes, thought to have been capable of containing between 30,000 and 40,000 men. This camp is situated at the entrance of the great valley of Strathmore, commanding the whole of the lowlands beneath the base of the Grampians, and also the passes of the highlands. The ancient castle of Finhaven, the ruins of which are still to be seen on the north side of the hill, was in former times the scene of great adventures. It was the residence of the well-known Earl of Crawfurd, who, from his ferocity, received the name of " the tiger earl"; he was chief of the Lindsays, who possessed a large part of the county, and his furious contests with the Ogilvys are among the most memorable conflicts of the kind recorded. The PARISH is about five miles in length, and about one mile and a half in breadth, containing 3870 acres. It is bounded on the north by the parish of Tannadice, on the south by the parishes of Rescobie and Aberlemno, ou the east by Aberlemno, and on the west by the parish of Kirriemuir. The surface is tolerably uniform, except in the southern quarter, in which rises the hill of Finhaven, cultivated to the very summit, and partly covered with larch and beech. Tradition reports the parish to have been formerly part of a great forest called the Forest of Claton. The chief properties are the estates of Finhaven and Newbarns, the former of which comprehends four-fifths of the whole lands, and was purchased in 1815 by the Marquess of Huntly for £65,000. The river Esk intersects the parish in several places; it is here 140 feet broad, and its banks being low, it frequently overflows, to the injury of the neighbouring grounds. Another stream is the Lemno rivulet, which, after a winding course of twelve or thirteen miles round the hill of Finhaven, falls into the Esk, only about a mile northward from its source. The SOIL is in general clayey, and its retentive nature has been found a great obstacle to agricultural improvement. It is fast being improved by thorough-draining. About ^850 acres are occasionally cultivated or in tillage; 900 acres are in wood, and 120 waste. All kinds of crreen crops and of grain are grown; of the latter, oats are most cultivated: the character of the husbandry is very good, and the crops are heavy and of fine quality. The cattle are the Angus: the few sheep that are kept are of the common black-faced breed, with some Cheviots, Leicesters, and South-Downs. This parish was behind most others in its husbandry at the commencement of the present century; but its advance since that period in the most approved usages, particularly in thoroughdraining, has been rapid. Much land has been reclaimed; thorn-hedge inclosures have been extensively formed, plantations have been made, and the farm-buildings are also in very good condition. The prevailing rock is sandstone, of which a quarry is wrought for building and other purposes. The population are mostly agricultural: till within the last few years a spinning-mill was in operation, which employed about sixty hands. Coal is the fuel generally used, being brought from other parts: an attempt was made by Mr. Ford, a late proprietor, to procure coal in the parish, but though he bored to the depth of 160 feet, his search for it was unsuccessful. There is a bridge over the Esk, and five small bridges cross the Lemno. Near the church is a very small village. The annual value of real property in Oathlaw is £3056. Ecclesiastically this place is in the presbytery of Forfar and synod of Angus and Mearns; patron, .1. Carnegy, Esq., of Finhaven. The stipend is £158, communion elements included; and there is a manse, with a glebe of about ten acres of arable laud. Oathlaw church is a small handsome building with a finely proportioned tower, situated about the centre of the parish, and surrounded by a number of old ashtrees j it was built in 1815, and seats upwards of 200 persons. The ancient church stood on the bank of the Esk. There is a benefaction called " Hanton's bequest", left in 1833 for the poor, at the discretion of the minister and elders. A parochial school is supported, in which Latin and the usual branches of education are taught; the master receives a salary of £34. 4., with about £10 fees, and has the accommodation of house and garden. There is also a parochial library, consisting of several hundreds of volumes.
