ALSTON, or ALSTON-MOOR, a market-town and parish in LEATH ward, county of CUMBERLAND, 29 miles (E. S. E.) from Carlisle, and 287 (N. N.W.) from London, containing, with the chapelry of Garrigill, 5699 inhabitants. The town is situated on the declivity of a steep hill, in a narrow valley, near the confluence of the rivers Nent and South Tyne, over each of which is a neat stone bridge. The houses, which are irregularly built, are chiefly of stone, roofed with slate, and the inhabitants are supplied with water conveyed by pipes from an excellent spring, about halt a mile distant, into four punts, or cisterns, conveniently placed in different parts of the town. A subscription library was established in 1821, in commemoration of the coronation of George IV.; and races are held on Easter Monday and Tuesday. An excellent new line of road has lately been made, under the superintendence of Mr. Mc Adam, from Hexham to Penrith, through Alston, which is shorter by several miles than that by way of Carlisle. In several parts are beautiful views of the surrounding country, particularly from Hartside, which embraces the counties of Cumberland and Westmorland, including the lake of Ulswater, and the mountains of the lake district, Solway Frith, and the adjacent Scottish shore. This district, which is enclosed on the west by the mountains Cross-fell and Hartside, and on all sides by high lands, is equally remarkable for its sterility of agricultural produce, and its abundance of mineral wealth. The lead mines, in which the inhabitants are chiefly employed, are very extensive and productive; there are not less than thirty-eight in the parish, and the quantity of lead produced in the year 1830 was about five thousand tons, which is considerably less than the average quantity for several years preceding. The ore contains a proportion of silver, averaging from eight to ten ounces per ton; and one of the mines, opened at Yadmoss in 1828, has produced ore containing ninety-six ounces of silver in each ton. Copper-ore has also been found in the same vein with the lead, and in many instances the same mine has been worked for copper-ore of excellent quality, and lead-ore, which is rich in silver. The grand aqueduct level, called "Nent Force," was cut by the trustees of Greenwich Hospital, under whom the estate is held, pursuant to an act which transferred these estates from the family of James, third Earl of Derwentwater, who was beheaded for high treason in the reign of George I.: this subterraneous canal is five miles in length, from its mouth near the town to the shaft of the mine; boats and guides are kept in constant readiness to conduct those who may wish to explore it. In the mines are several extensive caverns splendidly decorated with fluor- spar, shot into chrystals of every form and hue; and where the yellow copper-ore and pyrites are intermingled, nothing can exceed the brilliancy with which the prismatic colours are reflected. Of these, Tutman's hole has been explored to the distance of a mile from the entrance; and in that at Dun fell, on the side of Alston Moor, the chambers and windings are so intricate, that visitors have been glad to avail themselves of some clue to their return. Among other minerals found here are pyrites of iron, containing small portions of gold, tesselated ore, zink, phosphate and sulphate of lead, cobalt, &c. The crow coal, found on the moor, at a small depth below the surface, contains pyrites in large proportion; it burns with little flame, but emits an intense heat, and, mixed with clay, is made into fireballs. There are two large smelting furnaces, and several machines worked by water for crushing and washing the ore. The principal manufactures are those of shot, sewing thread, and flannel, which are extensively carried on; and there is also a public brewery on a large scale. The market is on Saturday: fairs are held on the last Thursday in May, Friday before the last day of September, and the first Thursday in November. Two of the county magistrates hold a petty session at the Swan Inn on the first Friday in every month, and courts leet and baron are held in the months next after Easter and Michaelmas. The living is a discharged vicarage, within the jurisdiction of the Consistorial Court of Durham, rated in the king's books at £7. 13., endowed with £600 private benefaction, £800 royal bounty, and £1000 parliamentary grant, and in the patronage of the Governors of Greenwich Hospital for two turns, and of William Jackson, Esq. for one. The church, dedicated to St. Augustine, was rebuilt in 1770. A chapel of ease is situated at Garrigill, a populous village four miles south-east of the town. There are places of worship for the Society of Friends, Independents, and Primitive and Wesleyan Methodists. The grammar school was rebuilt by subscription in 1828, and is endowed with £26 per annum. No scholars are gratuitously instructed, but the master, in consideration of the endowment, is limited to a certain scale of charges for boys attending it. There is a similar school at Garrigill, endowed with £7. 4. 1. per annum j and a Lancasterian school for two hundred children was erected in 1811, and is supported by subscription. At Nent Head, a large populous village on the eastern border of the parish, where a customary market is held on Thursday, a National school was established by the London Lead Company, in 1820, and is partly supported by them, and partly by the Governors of Greenwich Hospital. On Gildersdale fell is a stagnant pool, covered with mud several inches thick, which is used by the neighbouring people as paint: it produces colours resembling yellow ochre and Spanish brown, but has not been.analysed. The Roman road called Maidenway, traces of which are distinctly visible, crosses the western part of the parish; and on Hall hill, a little below the bridge over the Tyne, are the foundations of an ancient fortress, surrounded by a moat.
