In chronological order the Glen Dochartie and Garavaig bloomeries were probably the earliest of the Gairloch ironworks. The Fasagh works seem to have been intermediate between those and the historic series, which includes Furnace (Letterewe), Talladale, and the Red Smiddy. These last belong, as we have seen, to the seventeenth century.
Old inhabitants have a tradition that there was a bloomery in Tollie bay on Loch Maree. They say that after it was discontinued the business of tar boiling was carried on at the same place. If this were so, it must have been long ago, for no vestiges of old fir trees are now to be seen in the neighbourhood. Some small fragments of slag are found among the shingle in Tollie bay. Mr Macadam has analysed a sample of this slag, and is of opinion that it is lime-kiln slag; it contains 33 per cent. of carbonate of lime, and 64 per cent. of insoluble silicates, which include only 13 per cent. of metallic iron.
There are a few masses of slag near the entrance to the Gairloch churchyard. Owing to the crowded state of the graves within, some interments have recently taken place outside the churchyard, and this slag has been dug up. Mr Macadam finds that it contains 29½ per cent. of metallic iron, and 8¼ per cent. of insoluble silicates. He does not think this slag has been the result of iron-smelting.
Two notices not already quoted referring to iron mines or the manufacture of iron in the neighbourhood of Loch Maree or Loch Ewe ought to be mentioned before concluding this part of our subject.
The following is an extract from the letterpress (written in 1660) on the back of Blaeu's map of the north of Scotland—the old Dutch map previously referred to in these pages. It seems to speak of an outer and inner Loch Ewe, the latter (Loch Maree) surrounded by thick woods where in past years there had been iron mines (ysermijnen).
After describing Kintail, and then Lochcarron, it goes on to say (proceeding northwards):—"Dus voort-tredende komt men aen eenige onbekende zeeboesems, en den volght de zeeboesem Ew, en duysent schreden daer boven de binnenzee Ew, van alle zijden met dichte bosschen beslotten, daer in de voorgaende jaren ysermijnen gevonden zijn, en ick weet niet of men noch heden daer aen arbeyt."
The other notice occurs in the "Present State of Great Britain and Ireland," printed by J. Brotherton, London, 1742, where we read that "further on the same coast lies Loch Ewe with thick woods on all sides, where a great deal of iron was formerly made."
This brings to a close my remarks on the old ironworks of Gairloch. The dense forests of timber that yielded the charcoal used by the iron-smelters of old have disappeared, and coal, which is not found in Gairloch, is now the usual fuel for smelting. The local bog iron does not occur in such quantities as would be required for profitable working in the present day. It is therefore unlikely that the iron industry will again find a footing in Gairloch; but it must ever be interesting to recall what we know of the ironworks, both those commenced by the illustrious Earl of Kinnoull, and the others of more ancient date.
