The special sources and lines of research from which Scottish inductive Archæology may be expected to derive the additional data and facts which it requires for its elucidation are many and various. Let me here briefly allude to two only, and these two of rather opposite characters,—viz. (1), researches beneath the surface of the earth; and (2), researches among olden works and manuscripts.
In times past Scottish Archæology has already gained much from digging; and in times to come it is doubtless destined to gain yet infinitely more from a systematised use of this mode of research. For the truth is, that beneath the surface of the earth on which we tread—often not above two or three feet below that surface, sometimes not deeper than the roots of our plants and trees—there undoubtedly lie, in innumerable spots and places,—buried, and waiting only for disinterment,—antiquarian relics of the most valuable and important character. The richest and rarest treasures contained in some of our antiquarian museums have been exhumed by digging; and that digging has been frequently of the most accidental and superficial kind—like the discovery of the silver mines of Potosi through the chance uprooting of a shrub by the hand of a climbing traveller.
The magnificent twisted torc, containing some £50 worth of pure gold, which was exhibited in Edinburgh in 1856, in the Museum of the Archæological Institute, was found in 1848 in Needwood Forest, lying on the top of some fresh mould which had been turned up by a fox, in excavating for himself a new earth-hole. Formerly, on the sites of the old British villages in Wiltshire, the moles, as Sir Richard Hoare tells us, were constantly throwing up to the surface numerous coins and fragments of pottery. We are indebted to the digging propensities of another animal for the richest collection of silver ornaments which is contained in our Museum: For the great hoard of massive silver brooches, torcs, ingots, Cufic and other coins, etc., weighing some 16 lbs. in all, which was found in 1857 in the Bay of Skaill in Orkney, was discovered in consequence of several small pieces of the deposit having been accidentally uncovered by the burrowings of the busy rabbit. That hoard itself is interesting on this other account, that it is one of 130 or more similar silver deposits, almost all found by digging, that have latterly been discovered, stretching from Orkney, along the shores and islands of the Baltic, through Russia southward, towards the seat of the government of those Eastern Caliphs who issued the Cufic coins which generally form part of these collections—this long track being apparently the commercial route along which those merchants passed, who, from the seventh or eighth to the eleventh century, carried on the traffic which then subsisted between Asia and the north of Europe.
The spade and plough of the husbandman are constantly disinterring relics of high value to the antiquary and numismatist. The matchless collection of gold ornaments contained in the Museum of the Irish Academy has been almost entirely discovered in the course of common agricultural operations. The pickaxe of the ditcher, and of the canal and railway navvies, have often also, by their accidental strokes, uncovered rich antiquarian treasures. The remarkable massive silver chain, ninety-three ounces in weight, which we have in our Museum, was found about two feet below the surface, when the Caledonian Canal was dug in 1808. One of the largest gold armlets ever discovered in Scotland was disinterred at Slateford in cutting the Caledonian Railway. Our Museum contains only a model of it; for the original—like many similar relics, when they consisted of the precious metals—was sold for its mere weight in bullion, and lost—at least to Archæology—in the melting-pot of the jeweller, in consequence of the former unfortunate state of our law of treasure-trove. And it cannot perhaps be stated too often or too loudly, that such continued wanton destruction of these relics is now so far provided against; for by a Government ordinance, the finder of any relics in ancient coins, or in the precious metals, is now entitled by law, on delivering them up to the Crown for our National Museum, to claim "the full intrinsic value" of them from the Sheriff of the district in which they chance to be discovered—a most just and proper enactment, through the aid of which many such relics will no doubt be henceforth properly preserved.
But the results of digging to which I have referred are, as I have already said, the results merely of accidental digging. From a systematised application of the same means of discovery, in fit and proper localities, with or without previous ground-probing, Archæology is certainly entitled to expect most valuable consequences. The spade and pickaxe are become as indispensable aids in some forms of archæological, as the hammer is in some forms of geological research. The great antiquarian treasures garnered up in our sepulchral barrows and olden kistvaen cemeteries, are only to be recovered to antiquarian science by digging, and by digging, too, of the most careful and methodised kind. For in such excavations it is a matter of moment to note accurately every possible separate fact as to the position, state, etc., of all the objects exposed; as well as to search for, handle, and gather these objects most carefully. In excavating, some years ago, a large barrow in the Phœnix Park at Dublin, two entire skeletons were discovered within the chamber of the stone cromlech which formed the centre of the sepulchral mound. A flint knife, a flint arrow-head, and a small fibula of bone were found among the rubbish, along with some cinerary urns; but no bronze or other metallic implements. The human beings buried there had lived in the so-called Stone Period of the Danish archæologists. Some hard bodies were observed immediately below the head of one of the skeletons, and by very cautious and careful picking away of the surrounding earth, there was traced around the neck of each a complete necklace formed of the small sea-shells of the Nerita, with a perforation in each shell to admit of a string composed of vegetable fibres being passed through them. Without due vigilance how readily might these interesting relics have been overlooked!
The spade and mattock, however, have subserved, and will subserve, other important archæological purposes besides the opening of ancient cemeteries. They will probably enable us yet to solve to some extent the vexed question of the true character of our so-called "Druidical circles" and "Druidical stones," by proving to us that one of their uses at least was sepulchral. The bogs and mosses of Ireland, Denmark, and other countries, have, when dug into, yielded up great stores of interesting antiquarian objects—usually wonderfully preserved by the qualities of the soil in which they were immersed—as stone and metallic implements, portions of primæval costume, combs, and other articles of the toilet, pieces of domestic furniture, old and buried wooden houses, and even, as in the alleged case of Queen Gunhild, and other "bogged" or "pitted" criminals, human bodies astonishingly entire, and covered with the leathern and other dresses in which they died. All this forms a great mine of antiquarian research, in which little or nothing has yet been accomplished in Scotland. It is only by due excavations that we can hope to acquire a proper analytical knowledge of the primæval abodes of our ancestors,—whether these abodes were in underground "weems," or in those hitherto neglected and yet most interesting objects of Scottish Archæology, namely, our archaic villages and towns, the vestiges and marks of which lie scattered over our plains and mountain sides—always near a stream, or lake, or good spring—usually marked by groups of shallow pits or excavations (the foundations of their old circular houses) and a few nettles—generally protected and surrounded on one or more sides by a rath or earth-wall—often near a hill-fort—and having attached to them, at some distance in the neighbourhood, stone graves, and sometimes, as on the grounds about Morton Hall, monoliths and barrows.
Last year we had detailed at length to the Society the very remarkable results which Mr. Neish had obtained by simple persevering digging upon the hill of the Laws in Forfarshire, exposing, as his excavations have done, over the whole top of the hill, extensive Cyclopic walls of several feet in height, formerly buried beneath the soil, and of such strange and puzzling forms as to defy as yet any definite conjecture of their character. No doubt similar works, with similar remains of implements, ornaments, querns, charred corn, etc., will yet be found by similar diggings on other Scottish hills; and at length we may obtain adequate data for fixing their nature and object, and perhaps even their date. Certainly every Scotch antiquary must heartily wish that the excellent example of earnest and enlightened research set by Mr. Neish was followed by others of his brother landholders in Scotland.
At the present time the sites and remains of some Roman cities in England are being restored to light in this way—as the old city of Uriconium (Wroxeter), where already many curious discoveries have rewarded the quiet investigations that are being carried on;—and Borcovicus in Northumberland (a half-day's journey from Edinburgh), one of the stations placed along the magnificent old Roman wall which still exists in wonderful preservation in its neighbourhood, and itself a Roman town, left comparatively so entire that "Sandy Gordon" described it long ago as the most remarkable and magnificent Roman station in the whole island, while Dr. Stukely spoke of it enthusiastically as the "Tadmor of Britain." I was lately told by Mr. Longueville Jones, that in the vicinity of Caerleon—the ancient Isca Silurum of the Roman Itinerary—the slim sharpened iron rod used as a ground-probe had detected at different distances a row of buried Roman houses and villas, extending from the old city into the country for nearly three miles in length. Here, as elsewhere, a rich antiquarian mine waits for the diggings of the antiquary; and elsewhere, as here, the ground-probe will often point out the exact spots that should be dug, with far more certainty than the divining rod of any Dousterswivel ever pointed out hidden hoards of gold or hidden springs of water.
But it is necessary, as I have already hinted, to seek and hope for additional archæological materials in literary as well as in subterraneous researches. And certainly, one especial deficiency which we have, to deplore in Scottish Archæology is the almost total want of written documents and annals of the primæval and early mediæval portions of Scottish history. The antiquaries of England and Ireland are much more fortunate in this respect than we are; for they possess a greater abundance of early documents than we can boast of. Indeed, after Tacitus' interesting account of the first Roman invasion of Scotland under Agricola, and a few meagre allusions to, and statements regarding this country and its inhabitants by some subsequent classic authors, we have, for a course of seven or eight centuries, almost no written records of any authority to refer to. The chief, if not the only, exceptions to this general remark, consist of a few scattered entries bearing upon Scotland in the Irish Annals—as in those of Tighernach and Ulster; some facts related by Bede; some statements given in the lives and legends of the early Scottish, Welsh, and Irish saints;[14] and various copies of the list of the Pictish kings.
When we come down beyond the eleventh and twelfth centuries, our written memorials rapidly increase in quantity and extent. I have already alluded to the fact that three hundred quarto volumes—nearly altogether drawn from unpublished manuscripts—have been printed by the Scottish clubs within the last forty years. Mr. Robertson informs me that in the General Register House alone (and independently of other and private collections), there is material for at least a hundred volumes more; and the English Record Office contains, as is well known, many unedited documents referring to the building of various Scottish castles by Edward I., and to other points interesting to Scottish Archæology and History. The Welsh antiquaries have obtained from the Government offices in London various important documents of this description referring to Wales. Why should the antiquaries of Scotland not imitate them in this respect?
