The Clyde Mystery

The evidence of the bones, then, denotes any date except a relatively recent date, of 1556-1758; contrary to an hypothesis to be touched on later. It follows, from the presence of Bos at Elie (700 a. d.) that the occupants of the Clyde sites at Langbank may have lived there as late as, say, 750 a. d. But when they began to occupy the sites is another question.

If Roman objects are found, as they are, in brochs which show many relics of bronze, it does not follow that the brochs had not existed for centuries before the inhabitants acquired the waifs and strays of Roman civilisation. In the Nine Caithness Brochs described by Dr. Joseph Anderson, [43 - Proc. Soc. Ant. 1900-1901, pp. 112-148.] there was a crucible.. with a portion of melted bronze, a bronze ring, moulds for ingots, an ingot of bronze, bits of Roman “Samian ware,” but no iron. We can be sure that the broch folk were at some time in touch of Roman goods, brought by traffickers perhaps, but how can we be sure that there were no brochs before the arrival of the Romans?

We shall return to the question of the disputable relics of the Clyde, after discussing what science has to say about the probable date and original purpose of the wooden structures in the Clyde estuary. Nobody, it is admitted, forged them, but on the other hand Dr. Munro, the one most learned authority on “Lake Dwellings,” or “Crannogs,” does not think that the sites were ever occupied by regular “crannogs,” or lacustrine settlements, Lake Dwellings.

VIII – THE ORIGINAL DATE AND PURPOSE OF DUMBUCK AND LANGBANK

The actual structures of Langbank and Dumbuck, then, are confessedly ancient remains; they are not of the nineteenth century; they are “unique” in our knowledge, and we ask, what was the purpose of their constructors, and what is their approximate date?

Dr. Munro quotes and discusses [44 - Pp. 135, 177, 257-258, and elsewhere.] a theory, or a tentative guess of Dr. David Murray. That scholar writes “River cairns are commonly built on piled platforms, and my doubt is whether this is not the nature of the structure in question” (Dumbuck). A river cairn is a solid pile of stonework, with, perhaps, a pole in the centre. At Dumbuck there is the central “well” of six feet in diameter. Dr. Murray says that a pole “carried down to the bottom would probably be sunk in the clay, which would produce a hole, or well-like cavity similar to that of the Dumbuck structure.” [45 - Munro, pp. 177, 257, 258.]

It is not stated that the poles of river cairns usually demand accommodation to the extent of six feet of diameter, in the centre of the solid mass of stones, and, as the Langbank site has no central well, the tentative conjecture that it was a river cairn is not put forward. Dr. Murray suggests that the Dumbuck cairn “may have been one of the works of 1556 or 1612,” that is, of the modern age of Queen Mary and James VI. The object of such Corporation cairns “was no doubt to mark the limit of their jurisdiction, and also to serve as a beacon to vessels coming up the river.”

Now the Corporation, with its jurisdiction and beacons, is purely modern. In 1758 the Corporation had a “lower cairn, if it did not occupy this very spot” (Dumbuck) “it stood upon the same line and close to it. There are, however, no remains of such cairn,” says Dr. Murray. He cites no evidence for the date and expenses of the demolition of the cairn from any municipal book of accounts.

Now we have to ask (1) Is there any evidence that men in 1556-1758 lived on the tops of such modern cairns, dating from the reign of Mary Stuart? (2) If men then lived on the top of a cairn till their food refuse became “a veritable kitchen midden,” as Dr. Munro says, [46 - Munro, p. 139.] would that refuse exhibit bones of Bos Longifrons; and over ninety bone implements, sharpened antlers of deer, stone polishers, hammer stones, “a saddle stone” for corn grinding, and the usual débris of sites of the fifth to the twelfth centuries? (3) Would such a modern site exhibit these archaic relics, plus a “Late Celtic” comb and “penannular brooch,” and exhibit not one modern article of metal, or one trace of old clay tobacco pipes, crockery, or glass?

The answers to these questions are obvious. It is not shown that any men ever lived on the tops of cairns, and, even if they did so in modern times (1556-1758) they could not leave abundant relics of the broch and crannog age (said to be of 400-1100 a. d.), and leave no relics of modern date. This theory, or suggestion, is therefore demonstrably untenable and unimaginable.

Dr. Munro, however, “sees nothing against the supposition” that “Dr. Murray is right,” but Dr. Munro’s remarks about the hypothesis of modern cairns, as a theory “against which he sees nothing,” have the air of being an inadvertent obiter dictum. For, in his conclusion and summing up he writes, “We claim to have established that the structures of Dunbuie, Dumbuck, and Langbank are remains of inhabited sites of the early-Iron Age, dating to some time between the fifth and twelfth centuries.” [47 - Munro, p. 264.] I accept this conclusion, and will say as little as may be about the theory of a modern origin of the sites, finally discarded by Dr. Munro. I say “discarded,” for his theory is that the modern corporation utilised an earlier structure as a cairn or beacon, or boundary mark, which is perfectly possible. But, if this occurred, it does not affect the question, for this use of the structure has left no traces of any kind. There are no relics, except relics of the fifth (?) to twelfth (?) centuries.

In an earlier work by Dr. Munro, Prehistoric Scotland (p. 439), published in 1899, he observes that we have no evidence as to the when, or how of the removal of the stones of the hypothetical “Corporation cairn,” or “round tower with very thick walls,” [48 - These phrases are from Munro, Arch. and False Antiquities, pp. 138-139.] or “watch tower,” which is supposed to have been erected above the wooden sub-structure at Dumbuck. He tentatively suggests that the stones may have been used, perhaps, for the stone causeway now laid along the bank of the recently made canal, from a point close to the crannog to the railway. No record is cited. He now offers guesses as to the stones “in the so-called pavements and causeways.” First, the causeways may have probably been made “during the construction of the tower with its central pole,” (here the cairn is a habitable beacon, habitable on all hypotheses,) or, again, “perhaps at the time of its demolition” about which demolition we know nothing, [49 - Munro, p. 139.] except that the most of the stones are not now in situ.

Several authentic stone crannogs in Scotland, as to which we have information, possessed no central pole, but had a stone causeway, still extant, leading, e. g. from the crannog to the shore of the Ashgrove loch, “a causeway of rough blocks of sandstone slabs.” [50 - Munro, Prehistoric Scotland, p. 420.] If one stone crannog had a stone causeway, why should this ancient inhabited cairn or round tower not possess a stone causeway? Though useless at high water, at low water it would afford better going. In a note to Ivanhoe, and in his Northern tour of 1814, Scott describes a stone causeway to a broch on an artificial island in Loch Cleik-him-in, near Lerwick. Now this loch, says Scott, was, at the time when the broch was inhabited, open to the flow of tide water.

As people certainly did live on these structures of Langbank and Dunbuie during the broch and crannog age (centuries 5-12) it really matters not to our purpose why they did so, or how they did so. Let us suppose that the circular wall of the stone superstructure slanted inwards, as is not unusual. In that case the habitable area at the top may be reduced to any extent that is thought probable, with this limitation: – the habitable space must not be too small for the accommodation of the persons who filled up the eastern third of an area of from twelve to fourteen feet in breadth, and in some places a foot in thickness, with a veritable kitchen-midden, of “broken and partially burned bones of various animals, shells of edible molluscs, and a quantity of ashes and charcoal..” [51 - Munro, p. 130.]

But Dr. Munro assures me that the remains discovered could be deposited in a few years of regular occupancy by two or three persons.

The structure certainly yielded habitable space enough to accommodate the persons who, in the fifth to twelfth centuries, left these traces of their occupancy. Beyond that fact I do not pretend to estimate the habitable area.

Why did these people live on this structure in the fifth to twelfth centuries? Almost certainly, not for the purpose of directing the navigation of the Clyde. At that early date, which I think we may throw far back in the space of the six centuries of the estimate, or may even throw further back still, the Clyde was mainly navigated by canoes of two feet or so in depth, though we ought to have statistics of remains of larger vessels discovered in the river bed. [52 - See page 246 of Dr. Munro’s article on Raised Beaches, Proc. Roy. Soc. Edinburgh, vol. xxv. part 3. The reference is to two Clyde canoes built of planks fastened to ribs, suggesting that the builder had seen a foreign galley, and imitated it.] I think we may say that the finances of Glasgow, in St. Kentigern’s day, about 570-600 a. d., would not be applied to the construction of Dr. Munro’s “tower with its central pole and very thick walls” [53 - Munro, pp. 138, 139.] erected merely for the purpose of warning canoes off shoals in the Clyde.

That the purpose of the erection was to direct the navigation of Clyde by canoes, or by the long vessels of the Viking raiders, appears to me improbable. I offer, periculo meo, a different conjecture, of which I shall show reason to believe that Dr. Munro may not disapprove.

The number of the dwellers in the structure, and the duration of their occupancy, does not affect my argument. If two natives, in a very few years, could deposit the “veritable kitchen midden,” with all the sawn horns, bone implements, and other undisputed relics, we must suppose that the term of occupancy was very brief, or not continuous, and that the stone structure “with very thick walls like the brochs” represented labours which were utilised for a few years, or seldom. My doubt is as to whether the structure was intended for the benefit of navigators of the Clyde – in shallow canoes!

IX – A GUESS AT THE POSSIBLE PURPOSE OF LANGBANK AND DUMBUCK

The Dumbuck structure, when occupied, adjoined and commanded a ford across the undeepened Clyde of uncommercial times. So Sir Arthur Mitchell informs us. [54 - Proceedings Scot. Soc. Ant. vol. xxxiv. p. 462.] The Langbank structure, as I understand, is opposite to that of Dumbuck on the southern side of the river. If two strongly built structures large enough for occupation exist on opposite sides of a ford, their purpose is evident: they guard the ford, like the two stone camps on each side of the narrows of the Avon at Clifton.

Dr. Munro, on the other hand, says, “the smallness of the habitable area on both “sites” puts them out of the category of military forts.” [55 - Munro, p. 147.] My suggestion is that the structure was so far “military” as is implied in its being occupied, with Langbank on the opposite bank of Clyde by keepers of the ford. In 1901 Dr. Munro wrote, “even the keepers of the watch-tower at the ford of Dumbuck had their quern, and ground their own corn.” [56 - Proc. Soc. Ant. Scot. 1900-1901, p. 296.] This idea has therefore passed through Dr. Munro’s mind, though I did not know the fact till after I had come to the same hypothesis. The habitable area was therefore, adequate to the wants of these festive people. I conjecture that these “keepers of the watch-tower at the ford” were military “watchers of the ford,” for that seems to me less improbable than that “a round tower with very thick walls, [57 - Munro, p. 138.] like the brochs and other forts of North Britain,” was built in the interests of the navigation of Clyde at a very remote period. [58 - These structures, of course, were of dry stone, without lime and mortar. By what name we call them, “towers,” or “cairns,” is indifferent to me.]

But really all this is of no importance to the argument. People lived in these sites, perhaps as early as 400 a. d. or earlier. Such places of safety were sadly needed during the intermittent and turbulent Roman occupation.

X – THE LAST DAY AT OLD DUMBUCK

Suppose the sites were occupied by the watchers of the ford. There they lived, no man knows how long, on their perch over the waters of Clyde. They dwelt at top of a stone structure some eight feet above low water mark, for they could not live on the ground floor, of which the walls, fifty feet thick at the base, defied the waves of the high tides driven by the west wind.

There our friends lived, and probably tatooed themselves, and slew Bos Longifrons and the deer that, in later ages, would have been forbidden game to them. If I may trust Bede, born in 672, and finishing his History in 731, our friends were Picts, and spoke a now unknown language, not that of the Bretonnes, or Cymri, or Welsh, who lived on the northern side of the Firth of Clyde. Or the occupants of Dumbuck, on the north side of the river, were Cymri; those of Langbank, on the south side, were Picts. I may at once say that I decline to be responsible for Bede, and his ethnology, but he lived nearer to those days than we do.

With their ladder of fifteen feet long, a slab of oak, split from the tree by wedges, and having six holes chopped out of the solid for steps, they climbed to their perch, the first floor of their abode. I never heard of a ladder made in this way, but the Zuñis used simply to cut notches for the feet in the trunk of a tree, and “sich a getting up stairs” it must have been, when there was rain, and the notches were wet!

Time passed, the kitchen midden grew, and the Cymri founded Ailcluith, “Clyde rock,” now Dumbarton; “to this day,” says Bede, “the strongest city of the Britons.” [59 - Beda, book 1, chap. i.] Then the Scots came, and turned the Britons out; and St. Columba came, and St. Kentigern from Wales (573-574), and began to spread the Gospel among the pagan Picts and Cymri. Stone amulets and stone idols, (if the disputed objects are idols and amulets,) “have had their day,” (as Bob Acres says “Damns have had their day,”) and, with Ailcluith in Scots’ hands, “’twas time for us to go” thought the Picts and Cymri of Langbank and Dumbuck.

Sadly they evacuate their old towers or cairns before the Scots who now command the Dumbuck ford from Dumbarton. They cross to land on their stone causeway at low water. They abandon the old canoe in the little dock where it was found by Mr. Bruce. They throw down the venerable ladder. They leave behind only the canoe, the deer horns, stone-polishers, sharpened bones, the lower stone of a quern, and the now obsolete, or purely folk-loreish stone “amulets,” or “pendants,” and the figurines, which to call “idols” is unscientific, while to call them “totems” is to display “facetious and rejoicing ignorance.” Dr. Munro merely quotes this foolish use of the term totem by others.

These old things the evicted Picts and Cymri abandoned, while they carried with them their more valuable property, their Early Iron axes and knives, their treasured bits of red “Samian ware,” inherited from Roman times, their amber beads, and the rest of their bibelots, down to the minutest fragment of pottery.

Or it may not have been so: the conquering Scots may have looted the cairns, and borne the Pictish cairn-dwellers into captivity.

Looking at any broch, or hill fort, or crannog, the fancy dwells on the last day of its occupation: the day when the canoe was left to subside into the mud and decaying vegetable matter of the loch. In changed times, in new conditions, the inhabitants move away to houses less damp, and better equipped with more modern appliances. I see the little troop, or perhaps only two natives, cross the causeway, while the Minstrel sings in Pictish or Welsh a version of

“The Auld Hoose, the Auld Hoose,
What though the rooms were sma’,
Wi’ six feet o’ diameter,
And a rung gaun through the ha’!”

The tears come to my eyes, as I think of the Last Day of Old Dumbuck, for, take it as you will, there was a last day of Dumbuck, as of windy Ilios, and of “Carthage left deserted of the sea.”

So ends my little idyllic interlude, and, if I am wrong, blame Venerable Bede!

XI – MY THEORY OF PROVISIONAL DATE

Provisionally, and for the sake of argument merely, may I suggest that the occupancy of these sites may be dated by me, about 300-550 a. d.? That date is well within the Iron Age: iron had long been known and used in North Britain. But to the non-archaeological reader, the terms Stone Age, Bronze Age, Iron Age, are apt to prove misleading. The early Iron Age, like the Bronze Age, was familiar with the use of implements of stone. In the Scottish crannogs, admirably described by Dr. Munro, in his Ancient Scottish Lake Dwellings, were found implements of flint, a polished stone axe-head, an iron knife at the same lowest level, finger rings of gold, a forged English coin of the sixth or seventh century a. d., well-equipped canoes (a common attendant of crannogs), the greater part of a stone inscribed with concentric circles, a cupped stone, and a large quartz crystal of the kind which Apaches in North America, and the Euahlayi tribe in New South Wales, use in crystal gazing. In early ages, after the metals had been worked, stone, bronze, and iron were still used as occasion served, just as the Australian black will now fashion an implement in “palaeolithic” wise, with a few chips; now will polish a weapon in “neolithic” fashion; and, again, will chip a fragment of glass with wonderful delicacy; or will put as good an edge as he can on a piece of hoop iron.

I venture, then, merely for the sake of argument, to date the origin of the Clyde sites in the dark years of unrecorded turmoil which preceded and followed the Roman withdrawal. The least unpractical way of getting nearer to their purpose is the careful excavation of a structure of wood and stone near Eriska, where Prince Charles landed in 1745. Dr. Munro has seen and described this site, but is unable to explain it. Certainly it cannot be a Corporation cairn.

XII – THE DISPUTED OBJECTS

We now approach the disputed and very puzzling objects found in the three Clyde sites. My object is, not to demonstrate that they were actually fashioned in, say, 410-550 a. d., or that they were relics of an age far more remote, but merely to re-state the argument of Dr. Joseph Anderson, Keeper of the Scottish National Museum, and of Sir Arthur Mitchell, both of them most widely experienced and sagacious archaeologists. They play the waiting game, and it may be said that they “sit upon the fence”; I am proud to occupy a railing in their company. Dr. Anderson spoke at a meeting of the Scots Society of Antiquaries, May 14, 1900, when Mr. Bruce read a paper on Dumbuck, and exhibited the finds. “With regard to the relics, he said that there was nothing exceptional in the chronological horizon of a portion of them from both sites (Dumbuck and Dunbuie), but as regards another portion, he could find no place for it in any archaeological series, as it had ‘no recognisable affinity with any objects found anywhere else.’”

“For my part,” said Dr. Anderson, (and he has not altered his mind,) “I do not consider it possible or necessary in the meantime that there should be a final pronouncement on these questions. In the absence of decisive evidence, which time may supply, I prefer to suspend my judgment – merely placing the suspected objects (as they place themselves) in the list of things that must wait for further evidence, because they contradict present experience. It has often happened that new varieties of things have been regarded with suspicion on account of their lack of correspondence with things previously known, and that the lapse of time has brought corroboration of their genuineness through fresh discoveries. If time brings no such corroboration, they still remain in their proper classification as things whose special character has not been confirmed by archaeological experience.”

Sir Arthur Mitchell spoke in the same sense, advising suspension of judgment, and that we should await the results of fresh explorations both at Dumbuck and elsewhere. [60 - Proceedings Soc. Scot. Ant. 1899-1900, vol. xxxiv. pp. 456-458.] Dr. Murray said that the disputed finds “are puzzling, but we need not condemn them because we do not understand them.” Dr. Munro will not suspend his judgment: the objects, he declares, are spurious.

XIII – METHOD OF INQUIRY

I remarked, early in this tract, that “with due deference, and with doubt, I think Dr. Munro’s methods capable of modification.” I meant that I prefer, unlike Dr. Munro in this case, to extend the archaeological gaze beyond the limits of things already known to occur in the Scottish area which – by the way – must contain many relics still unknown.

“Let Observation with extensive view

Survey mankind from China to Peru,”

to discover whether objects analogous to those under dispute occur anywhere among early races of the past or present. This kind of wide comparison is the method of Anthropology. Thus Prof. Rhys and others find so very archaic an institution as the reckoning of descent in the female line, – inheritance going through the Mother, – among the Picts of Scotland, and they even find traces of totemism, an institution already outworn among several of the naked tribes of Australia, who reckon descent in the male line.

Races do not, in fact, advance on a straight and unbroken highway of progress. You find that the Kurnai of Australia are more civilised, as regards the evolution of the modern Family, than were the Picts who built crannogs and dug canoes, and cultivated the soil, and had domesticated animals, and used iron, all of them things that the Kurnai never dreamed of doing.
