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.
