2. Fasagh.
The most extensive remains of ironworks on Loch Maree are on the south side of the Fasagh burn, close to where it runs into the loch. This burn comes from Loch Fada, a considerable sheet of water to the north of Slioch. There are remains of a sluice or dam where the burn leaves Loch Fada, evidently used long ago to regulate the water supply. The burn flows into Loch Maree at its south-east corner, close to the head of the loch. There are indications of a large artificial bank, probably the remains of a dam, formed at right angles to the burn, near the site of the ironworks; but the burn has of late years been subject to great floods, that have to some extent varied its course, and altered the surrounding features.
There are two places which seem to have been the sites of furnaces or bloomeries; at each of these spots, which are near each other, and have a small watercourse (now dry) running alongside, there is a mass of slaggy material surrounding a root or stump of a tree. In the same part is a quantity of blackish material, weathering red and splitting on exposure like quicklime, and on all sides are heaps and scattered masses of dark heavy slag No. 1. The tuyere (see [illustration]) of a furnace was in 1882 removed from a cottage close by, where it had been for a long time; it is now in the possession of Mr Macadam, and is to be placed in the Museum of the Society of Antiquaries of Scotland. I have obtained from an old man at Kenlochewe, an ancestor of whose brought it from the Fasagh ironworks, a curious article (see [illustration]); it is of cast-iron, and seems to have formed part of the apparatus for working a large forge-hammer. In examining the furnaces with Mr Macadam in April 1886, we found a portion of a thin bar, which appeared to be of iron. They say that a massive hammer head brought from Fasagh was long at Culinellan, and that an anvil at the Kenlochewe smithy was formed from part of it. Not far from the sites of the furnaces is a mound of rust-coloured earth like that found with bog iron (ore No. 1). There are evidences of extensive charcoal burnings on the other side of the burn, to the west of the ironworks.
Mr Macadam has supplied the following results of his analyses of samples of substances obtained at Fasagh:—The slaggy material from tree roots contains 66 per cent., the blackish material 73 per cent., and the dark slag 68 per cent. of metallic iron; the slag also contains 11 per cent. of silica; the bar of iron contains 63 per cent. of metallic iron, and a large quantity of carbon.
About half a mile to the east of the Fasagh works, at the foot of the crag called Bonaid Donn, is a small circular pond, or rather a large hole in the middle of a circular marsh. It is called Lochan Cul na Cathrach. There is a perpetual flow of spring water from this hole, and the surrounding marsh prevents close approach to it. It is the common tradition, accepted with the fullest credence, that into this hole the last ironworkers at Fasagh threw all their implements when the furnaces were discontinued. Possibly a drag might bring something to light, or the hole might be drained. The tradition is so firmly believed, that it produces on one's mind a strong impulse to search the hole, and try to find something bearing on the nature and history of the Fasagh ironworks.
From the character of the slags, the comparatively complete state of the remains, and from the tuyere and other things having been discovered, it seems probable that the Fasagh works, whilst belonging to the ancient class of ironworks, were amongst the most recent of that class; and Mr Macadam thinks it possible that Sir George Hay may have commenced his operations at this place in continuation, no doubt, of older ironworks.
3. Furnace, Letterewe.
The remains of the ironworks at the hamlet of Furnace, a mile south-east of Letterewe, are perhaps the most generally interesting in Gairloch, as being especially identified with Sir George Hay. The furnace which gives its name to the hamlet is on the north-west bank of the "Furnace burn," about one hundred yards from its confluence with Loch Maree. The remains of the furnace are tolerably complete, and a hole in its lower part looks as if it had been the aperture for the blast. On the banks of the burn are masses of sandstone, which formed part of the furnace. Some fragments of vitrified bricks are also to be seen. In the soil of the adjoining field, and in its fence walls, are quantities of the ores 2 and 3. In places the soil is quite red with fragments of hematite. In other places it is stained black with charcoal burnings, and many fragments of charcoal are to be found. No doubt the water-power of the burn was utilised, and Loch Maree afforded an easy means of transport of imported ores from Poolewe, where they were landed.
The slags found about this furnace are of both classes. May we not conclude from this fact, that Sir George Hay commenced the manufacture of iron on the old methods anciently in vogue, and that it was at Letterewe that he began the improved processes which were afterwards carried to still greater perfection at the Red Smiddy? This furnace belongs of course to the historic class.
