works attain old age. Every evil effect about Swansea, however, is ascribed to the copper smoke. The houses in this district are remarkable for clean exterior: the custom of whitewashing the roofs, as well as the walls, produces a pleasing effect, and is a relief to the eye in such a desert. There are eight large copper smelting establishments, besides several rolling-mills, now at work; the whole country is covered with tram-roads and coal-pits, many of which vomit forth their mineral treasures close to the road side. At Landore, about two miles from Swansea, is a large steam-engine, made by Bolton and Watt, which was formerly the lion of the neighbourhood. This pumping engine draws the water from all the collieries in the vale, throwing up one hundred gallons of water at each stroke: it makes twelve strokes in a minute, and consequently discharges 72,000 gallons an hour. This engine, however, is very inferior in construction and finish to the pumping engines of Cornwall, some of which are nearly three hundred horsepower. At the consols mines, there are two engines, each with cylinders of ninety inches in diameter, and everything about them kept as clean as a drawing-room. What an extraordinary triumph of the ingenuity of man, when it is considered that one of these gigantic engines can be stopped in an instant, by the mere application of the fingers and thumb of the engineer to a screw! The quantity of coals consumed by the copper-works is enormous. We have heard that Messrs. Vivians, who have the largest works on the river, alone consume 40,000 tons annually: this coal is all small, and not fit for exportation. The copper trade may be considered as comparatively of modern date. The first smelting works were erected at Swansea, about a century ago; but now it is calculated that they support, including the collieries and shipping dependant on them, 10,000 persons, and that 3,000
l. is circulated weekly by their means in this district. Till within the last few years, there were considerable copper smelting establishments at Hayle, in Cornwall; but that county possessing no coals, they were obliged to be abandoned, as it was found to be much cheaper to bring the ore to the coal than the latter to the ore. Formerly, from the want of machinery to drain the water from the workings (copper being generally found at a much greater depth than tin), the miners were compelled to relinquish the metallic vein before reaching the copper: indeed, when it was first discovered, and even so late as 1735, they were so ignorant of its value, that a Mr. Coster, a mineralogist in Bristol, observing large quantities of it lying amongst the heaps of rubbish round the tin mines, contracted to purchase as much of it as could be supplied, and continued to gain by Cornish ignorance for a considerable time. The first discoverer of the ore was called Poder (it long went by his name), who actually abandoned the mine in consequence; and we find that it was for some time considered that "
the ore came in and spoilt the tin." In the year 1822 the produce of the Cornish copper mines amounted to 106,723 tons of ore, which produced 9,331 tons of copper, and 676,285
l. in money. In the same year, the quantity of tin ore raised was only 20,000 tons. The Irish and Welsh ores are generally much richer than those of Cornwall; but occasionally they strike on a very rich
lode (or vein) in that county. Last spring, some ore from the Penstruthal mine was ticketed at Truro, at the enormous price of 54
l. 14
s. per ton; and a short time previous, in the Great St. George Mine, near St. Agnes, a lode was struck five feet thick, which was worth 20
l. a ton. There are only six other copper-works in the kingdom besides those of Swansea, five of which are within fifteen miles of that town; the other is at Amlwch (in the isle of Anglesea), where the Marquess of Anglesea smelts the ore raised in his mines there. The annual import of ore into Swansea in 1812 was 53,353 tons; in 1819, 70,256 tons were brought coastwise: besides which, several thousand tons of copper ore are imported from America every year. Since this period there has been a large increase. Most of the ships which are freighted with copper ore load back with coal, for the Cornish and Irish markets. Of bituminous, in 1812, 43,529 chalders, and in 1819, 46,457 chalders were shipped coastwise, besides a foreign trade of about 5,000 chalders every year. Most of this goes to France, the French vessels coming here in ballast for this purpose; but all coal shipped for abroad must be riddled through a screen composed of iron bars, placed three-eighths of an inch apart, as it is literally almost dust. Great hopes are now entertained here that government will abolish the oppressive duty on sea-borne coal. In the stone-coal and culm
3 trade, Swansea and Neath almost supply the whole kingdom. Independent of foreign trade, 55,066 chalders of culm and 10,319 tons of stone-coal were shipped coastwise in 1819: last year the ports of Swansea and Neath shipped 123,000 chalders of stone-coal and culm. Stone-coal improves in quality as it advances westward. That of Milford, of which however only about 6,000 chalders are annually exported, sells generally at from 50
s. to 60
s. per chaldron in the London market—a price vastly exceeding the finest Newcastle coal. It emits no smoke, and is used principally in lime-burning and in manufactories where an intense heat and the absence of smoke is required. The Swansea culm is mostly obtained about thirteen miles from the town. The bituminous coal mines in the vale of Tawy are fast getting exhausted, and the supply of coal must at no distant day be drawn farther westward, near the Burry River, where the quality of the coal is much improved, approaching nearer to that of Newcastle. The national importance of the inexhaustible supply of this mineral which exists in Wales, is incalculable; but as it has already been alluded to in
The Mirror, in an extract from Mr. Bakewell's Geology, we will not farther pursue the subject.
4 While mentioning the trade of Swansea, we should not omit to state that two extensive potteries, tin and ironworks, and founderies, &c., and bonding warehouses and yards for foreign goods, &c. exist here.
