SORN, a parish, in the district of Kyle, county of Ayr, 3^ miles (E.) from Mauchline; containing, with the former quoad sacra district of Catrine, 4054 inhabitants. This place, anciently called Dalgain, derived that Celtic appellation from the nature of the soil, and its present name, which is also of Celtic origin, from the position of its castle on a bold promontory projecting into the river Ayr. The time of the erection of this castle, and the name of its original founder, are not recorded; but it is thought to be of great antiquity. In the early part of the 15th century the fortress, and the lands pertaining to it, became the property of the ancestor of the Hamihon family, one of whom, Sir William Hamilton, was lord treasurer of Scotland in the reign of James V., who paid a visit to Sir William on the marriage of his daughter to Lord Seaton, and remained for some time at the castle. By this marriage the estate descended to the Earl of Wintoun, who sold the castle and lands to the Loudoun family; and after passing to various other proprietors, they were purchased about half a century since by the family of the present owner. The PARISH is about six miles and a half in length and of nearly equal breadth, comprising '23,9.50 acres, of which 1'2,600 are arable, 780 woodland and plantations, and the remainder hill pasture and moss. Its surface is pleasingly varied with plains, and with hills of various elevation, the highest of which, on the north-east boundary of the parish, is nearly 1600 feet above the level of the sea. The river Ayr intersects the parish from east to west, and in its course receives numerous streams, several of which have their rise in the higher grounds here: of these the Cleugh, a picturesque burn, flows along a deep and richly-wooded dell abounding with beautiful scenery, into the Ayr, near the castle; thus forming a strikingly romantic feature in the landscape of the parish, which is also embellished with flourishing plantations. On the banks of the Ayr the soil is gravelly, on the higher grounds a reddish clay, and on the hills a kind of peat-moss resting on a substratum of clay: the crops are oats, potatoes, and hay, with a few acres of wheat and barley; beans, turnips, and carrots. The system of agriculture is improved, and the rotation of crops generally adopted; furrow-draining is extensively practised, and much indifferent land by that means has been rendered productive. Lime is found in abundance, and forms the principal manure. The farmbuildings are substantial and commodious, and on many of the farms are threshing-mills, mostly driven by horses. The breeds of live-stock are not much attended to; the cattle are chiefly of the Cunninghame, and the sheep of the black-faced, breed. Few horses are reared except some for husbandry, and these are of an inferior kind. The annual value of real property is £99*0. In this district the substrata are limestone, ironstone, slate-clay, sandstone, and coal. The limestone, which is of excellent quality, is extensively wrought for manure and other uses; and the ironstone, though never smelted here, was formerly sent in great quantities to the works of the Muirkirk Iron Company, and was found to contain a large proportion of iron. The coal was once wrought near the village of Sorn, producing an abundant supply at a moderate expense, and it has been in contemplation to commence operations for that purpose in other parts of the parish: coal is brought at present from the collieries at Auchinleck,four miles distant. In the parish are a mill for grain, to which is attached a saw-mill; a carding-mill, a public brewery, and two licensed private breweries. Sorn Castle, Gilmillscroft, Auchmaunoch, Glenlogan, Catrine Bank, and Kingswell are the principal houses. The village of Sorn is pleasantly situated on the road from Ayr to Muirkirk, in a vale of considerable extent watered by the river Ayr, and is chiefly inhabited by agricultural labourers: a few of the inhabitants, however, are employed in hand- loom weaving. A sub-post-oRice has been established here; and facility of communication is afforded with the neighbouring places by good roads which pass through the parish, and by a stone bridge over the Ayr. Fairs are held on the second Tuesday in March, O. S., and the first Monday in November; they are for the sale of cattle and agricultural produce. A race is held on the fair days. The village of Catrine, situated on the north bank of the river, is described under its own head. The parish was separated from that of Mauchline in 169'2, when the chapel of ease of Sorn, which had been erected more than thirty years, became the church. It is in the presbytery of Ayr, synod of Glasgow and Ayr, and in the patronage of Mrs. Agnes Somervell. The minister's stipend is £195. 11., with a manse, and a glebe valued at £15 per annum. Sorn church, built in 1658, was thoroughly repaired in 1826, and is adapted for a congregation of 61 1 persons. The parochial school is situated close by the church, not far from the village of Sorn; the master has a salary of £34. 4., with the fees, and a house and garden. There are also places of worship and schools at Catrine. A friendly society was established in 1832, which has a fund of more than £250. Dr. Matthew Stewart, professor of mathematics in the university of Edinburgh, and father of Professor Dugald Stewart, was occasionally a resident of this parish; and the house in which he lived is still remaining. On his decease, his son became heritor of the estate, and spent much of the earlier period of his life here. Mr. Stewart died in 1828, and was succeeded by his son, Lieutenant- Colonel Matthew Stewart, who has erected a handsome dwelling-house on another site: this house, from the circumstance of James V. having, on his way to Sorn Castle, reposed himself by the side of a well near the place, bears the name of Kingswell.
