STRONTIAN, a quoad sacra parish, chiefly in the parish of Ardnamurchan, district of Argyll, and partly in the parish of Morvern, district of Mull, county of Argyll, 235 miles (S. W. by W.) from Fort William; the Ardnamurchan portion containing 982 inhabitants. This place, which is situated on the shores of Loch Sunart, derived its earliest importance from the opening of some valuable lead-mines, in 1722, by Sir Andrew Murray, who let them on lease to the York Buildings' Company. Though it is certain that these mines had been wrought at a much earlier period, yet it was not till after they had been leased to the company that any effectual means were adopted for bringing them into profitable operation. An English mining establishment was soon afterwards formed here, in which 500 men were regularly employed: appropriate buildings, with the requisite machinery for working the mines to advantage, were erected; and a village, called New York, was raised for the accommodation of the miners. These mines continued in extensive operation, yielding an ample revenue, both to the York Buildings' Company and their lessors, till about the year 1818, when they began to decline. They were also let in the year 1836, but were shortly discontinued; and though they are still wrought to a limited extent, every vestige of the village of New York has been obliterated by the plough. Traces of lead-ore are found in many parts of Sunart, yet no other mines than those of Strontian have been opened. There are two veins of ore connected with these works, one of which, although difficult to work, is said to contain a large proportion of silver, and produces lead of excellent quality; the other is traversed with dykes of whin, and the galena is plentifully embedded in the blue stone or calc spar. A new mineral called after this place, where it was first discovered, occurs in abundance. It is a kind of earth, of a whitish or light green colour, with a small degree of transparency, and possessing properties between those of lime and barytes. It was analysed by Dr. Kirwan, and Dr. Hope of Edinburgh, and found to contain 6r21 parts of pure earth, 3020 parts of carbonic acid gas, and 8'59 parts of water. The parish comprises the eastern, and larger, portion of the district of Sunart, in Ardnamurchan parish; and also part of Morvern parish. From these two parishes Strontian was separated for ecclesiastical purposes, by the presbytery, on the erection of a church in 1827: a quoad sacra parish was formed under act of the General Assembly in 1833. It is nearly twenty-five miles in extreme length, and varies greatly in breadth, containing 49,148 acres, of which 1380 are arable, 5558 meadow and pasture, 1583 woodland and plantations, and the remainder moorland, moss and waste. The surface, like that of the parish of Ardnamurchan generally, is diversified; in the district are some mountains of considerable elevation (particularly noticed in the article on Ardnamurchan), and the beautiful and fertile valley of Strontian, where most of the inhabitants reside. Near the eastern extremity of Loch Sunart, which is navigable to its head, is the harbour of Strontian, possessing good anchorage for the vessels arriving with supplies for the use of the district: till lately, a steamer plied regularly, affording direct communication with Glasgow. The soil of the arable lands is fertile, and under good cultivation; the hills furnish pasturage for sheep, generally of the black-faced kind, and the moorlands for black-cattle, of the Argyllshire breed, of which latter great numbers are reared, and sent to the Glasgow market. There are considerable remains of natural wood, consisting of oak, birch, ash, alder, and hazel; and the plantations, which are extensive and regularly thinned, are chiefly plane, ash, oak, and the various kinds of fir. Strontian House, the seat of Sir James Milles Riddell, Bart., is a handsome modern mansion, pleasantly situated in grounds tastefully laid out, and embellished with thriving plantations. The village consists of some irregular clusters of neat houses, interspersed with cottages occupied by persons employed in the leadmines; the post-office here has a daily delivery, and there is a good inn. Fairs for sheep and black-cattle are held on the Thursdays before the last Wednesdays in May and October. Facility of communication is afforded by the turnpike road leading from the village to Corran Ferry, which is a continuation of the parliamentary road from Kinloch-Moidart. Strontian is in the presbytery of Mull, and synod of Argyll: the minister's stipend is £120, with a manse, and a glebe valued at £5 per annum; patron, the Crown. The church, erected by government in 1827, is a substantial structure, situated in the vale of Strontian, and containing 650 sittings. The school for the district was built by Sir James Milles Riddell, and is supported by government, who allow the master a salary of £30, besides the fees: connected with the school is a small library.
