ANCIENT GAIRLOCH IRONWORKS.
Many visitors to Gairloch, and not a few of the inhabitants, will learn with astonishment that the manufacture of iron was carried on in the parish from remote times, and that there are still abundant remains to testify to the magnitude and importance of the industry. There are many places in this wild and picturesque Highland district where are to be seen to this day large heaps of slag and dross, and remains of blast-furnaces or bloomeries; whilst many acres of arable ground, as well as of uncultivated moorland, are still thickly strewn with fragments of charcoal and of several kinds of iron ore.
The remains of ironworks examined in Gairloch may be roughly divided into two classes, viz:--(1) The ancient ironworks, of which there are no historical records extant; and (2) The historic ironworks of Loch Maree.
The ancient ironworks or bloomeries are the subject of our present chapter. Some of them appear, as we should expect, to belong to a later period than others, but nothing can be said with precision about the date of any of them. They will be described in Part I., chap. xx.
There are some interesting notes on the subject of ancient Highland ironworks in the curious book entitled "Remarks on Dr Samuel Johnson's Journey to the Hebrides, by the Rev. Donald M'Nicol, A.M.," published in 1779, and extracted in Appendix G. Mr M'Nicol does not give his authorities, but there is ample ocular demonstration of the truth of his statement, that "the smelting and working of iron was well understood and constantly practised over all the Highlands and Islands for time immemorial." Other writers have expressed the opinion, that iron was made throughout Great Britain long before the Roman invasion.
Perhaps a coin now in my possession, which was found some years ago in a field on the bank of the river Went in Yorkshire, near large quantities of ancient heavy iron slag, may be taken as giving some clue to the date of the older ironworks. It is an ancient British coin of the type of the quarter stater of Philip II. of Macedon. The British coinage is supposed to have been in existence at least as far back as 150 B.C., and this is one of the early types.
The querns frequently found in all parts of the Highlands shew that the ancient inhabitants grew some corn,--that they had some acquaintance with "the staff of life." It seems a reasonable inference, that they used iron implements for tilling their lands and securing their crops. It is certain that some iron weapons, tools, and implements, besides those employed in agriculture, were in use in the Highlands in those old days. An iron axe-head, of the shape of the bronze celt figured among our illustrations, and with the aperture for the handle similarly in a line with its axis instead of at right angles to it, was found in 1885 in the garden at Inveran; its remains are much eaten by rust, but there is enough to shew that this iron axe is of an old type. It may be objected, that if iron implements for peace or war were extensively used in ancient days there would be more relics of them. The obvious reply to such an objection is, that iron is so liable to oxidation that most of the smaller iron articles of ancient times must have perished from that cause. Many of the small masses of rust-cemented gravel and earth, found everywhere, may have originally had for their nucleus an ancient iron implement, or a fragment of one. If it be allowed that the Picts or other early inhabitants of the north used iron tools and weapons, the question at once arises,--Where and how did they procure them? The remains of the ancient class of ironworks supply the answer. Those so-called savages well knew where to procure iron, and how to fabricate from it the articles they required,--another proof that the Picts were by no means the uncivilised barbarians that some people suppose.
The ancient ironworks of Gairloch were probably not more numerous than those of some other parts of the Highlands and Islands. There is little doubt but that many of the remains, both in Gairloch and elsewhere, have been obliterated by the husbandman, or concealed by overgrowth of heather and other plants. In many places throughout Sutherlandshire, Ross-shire, and Inverness-shire, as well as in other Scottish counties, there are large quantities of iron slag. The Inverness Scientific Society have examined remains of ancient iron-smelting near Alness in Easter Ross. The Rev. Dr Joass, of Golspie, and Mr D. William Kemp, of Trinity, have to a certain extent investigated some Sutherlandshire remains. There are also quantities of slag on the Braemore estate, on the shores of Loch Rosque between Achnasheen and the eastern boundary of Gairloch parish (Part IV., chap, iii.), and in many other parts of Wester Ross, as well as in the island of Soa off the west coast of Skye, and many other places.
At the iron-smelting works near Alness a native hematite iron ore was used, as well as what is termed bog iron. Bog iron is also believed to have been used at a bloomery near Golspie, Sutherlandshire. This bog iron appears to have been commonly employed by the ancient ironworkers; it was extracted by the action of water from ferruginous rocks and strata, and was accumulated at the bases of peat bogs. In process of time granular masses of oxides of iron were thus formed, sometimes covering a considerable area. Within the parish of Gairloch there are still quantities of bog iron to be seen, apparently formed exactly in the manner described. The localities will be stated in Part I., chap.
