KILDALTON, a parish, in the district of Islay, county of Argyll, 14 miles (E. by S.) from Bowmore; containing, with the village of Port-Ellen and the former quoad sacra district of Oa, 3315 inhabitants, of whom 904 are in Port-Ellen.- This parish, which is supposed to have taken its name from one of the step-sons of the Macdonalds, who was buried in the church, forms the south-eastern portion of the isle of Islay, and is bounded on the north-east by the sound of Islay, and on the south-west by the Atlantic Ocean. It is twenty-four miles in length and seven in breadth; the number of acres has not been ascertained, and only a very small portion of the parish is arable. The surface is broken by a range of hills extending from south-west to northeast, and increasing in elevation towards the sound of Islay; of these, Benvigory and Mc Arthur's Head are the highest. To the north-west of the hills is a large extent of level ground, gradually coming into cultivation; and the valleys, which intersect the parish from east to west, are in general fertile, yielding good crops of oats, barley, and potatoes. There are numerous excellent springs in various places, but no rivers of any importance; also several small lakes, in most of which are found trout of large size, and in some pike. The coast extends for more than fifty miles; it is generally low and rocky, and is indented with bays, the principal of which are Port- Ellen, Lagamhulin, Lochknock, Lochintallin, Ardmore, Kenture, Aross, Claigean, Ardtealla, and Proaig. The most prominent headlands are, Mc Arthur's Head on the north, Ardmore Point on the east, and the Mull of Oa on the south. In different parts the rocks are perforated with caverns of romantic appearance, one of which is about 300 feet in circumference, and nearly 200 feet in depth: the sea flows into this cavern through two apertures, one of them a lofty arch of considerable span, and the other a narrow fissure in the rock. There are also numerous small islands near the coast, the chief of which are Texa, EUan-nan-Caorach, Ellain-Imergay, the Ardelisters, and a cluster of islands in the bay of Ardraore. In this parish the soil, is extremely various. The system of agriculture is improving; and within the last few years considerable tracts of land have been brought into cultivation under the auspices of the proprietor, W. F. Campbell, Esq., of Islay, who has also formed plantations of large extent. These consist of oak, ash, fir, plane, horse-chesnut, and beech, which are all in a thriving state; and in the north-east of the parish are many acres of brushwood. Numbers of black-cattle of the native breed, and sheep, are reared in the pastures; and great attention is paid to their improvement. The annual value of real property in the parish is £4562. The principal substrata are slate, granite, whinstone, and limestone; and in some parts indications of ironstone are observed, with appearances of lead and copper ore; but the slate and limestone only are wrought. A neat shooting-lodge has been erected by Mr, Campbell, in which he occasionally resides during the season. There are five distilleries, employing about forty persons. Fairs for black-cattle are held at Port-Ellen, in the beginning of June, July, August, September, and November; and a runner from the post-office at Bowmore conveys letters three times a week to a receiving-house at Lagamhulin. Ecclesiastically the parish is within the bounds of the presbytery of Islay and Jura, synod of Argyll. The minister's stipend is £158. 6. 8., of which two-thirds are paid from the exchequer; with a gratuity of £5 from the heritor, a manse, and a glebe valued at £25 per annum: patron, the Crown. Kildalton church, situated nearly in the centre of the parish, is a neat structure, erected in 1816, and enlarged in 1830, containing 600 sittings. A church has been built at Oa, in the southwest. The parochial school is well attended; the master has a salary of £25, with a house and garden, and the fees average £10 per annum. A school is supported by the Society for Propagating Christian Knowledge, who allow the master a salary of £16, with a house and some land; and there is another school, to the master of which the Gaelic Society pay £20. In Oa is a parliamentary school with a salary of £30; and at Kenture, Lagamhulin, and Kintraw are General Assembly schools. The poor have the interest of a bequest of £100 by Major Mc Neill. There are remains of several churches, consisting chiefly of the roofless walls: near the ruins of the old church of Kildalton are two crosses of grey granite, one of which is richly ornamented with sculpture. Vestiges of three ancient forts may be seen in the parish at the Mull of Oa, near Port-Ellen, and at the bay of Lagamhulin: the first is supposed to have been erected by the Danes; the fort near Lagamhulin, called Dun-naom-haig, is thought to have been built by the Macdonalds, and was the last stronghold that they possessed.
