The interior of the structure was divided into two stories, each about four feet in height (plate III. figs. 1 and 2); its flat roof was sixteen feet beneath the original surface; therefore, nearly twenty-five feet of bog must have grown around it since its first erection; a piece of a leather sandal,[55] a flint arrow-head and wooden sword were found; the latter relic was quite perfect when dug up, it was subsequently broken into two pieces, one of which—the pointed end—may be seen in the Museum, R.I.A., and is here represented (fig. 4); the portion remaining measures twenty-seven and a-half inches in length, its greatest breadth being three inches.

The depth at which the hut was buried, and the flint and stone implements found in it, seem to prove unquestionably its extreme antiquity; added to which, upon the level of the floor, and extending all around, were the corkers of a forest of hard wood trees that had co-existed with the occupation of this structure. Wood, in large masses, when either thoroughly immersed in water or buried under ground, lasts longer in a semi-decomposed state than is generally supposed, for calcined ends of timber antæ and rafters were dug out from the pseudo site of Troy.[56]

At the time of Captain Mudge’s discovery, so little was known on the subject of lake dwellings, that many were the conjectures floated in connexion with this Donegal “find.” Now, however, this famous log house is pronounced to be simply a very well preserved example of the ordinary crannog hut of an extremely early period, i.e. of a time when axe-heads of stone were still in use, and when metal, if known at all, was so precious that ordinary weapons were occasionally at least formed out of hard wood. That the structure in question occupied a crannog will be sufficiently obvious to any inquirer who examines the model of it preserved in the Royal Irish Academy. The stakes represented in situ, to the left of the illustration (plate II.), are plainly remains of the stockade, one timber of which appears in the foreground; and, in the sides of the drain made to carry off the water from the excavation, Captain Mudge observed a number of ends of large oak logs placed in regular order, portion evidently of the usual crannog foundation.[57]

In 1867, the remains of a dwelling brought to light in the townland of Cargaghoge, near Carrickmacross, county Monaghan, is thus described:—[58] A man engaged in cutting turf, having uncovered the ends of three planks of oak, the circumstance, when reported to Mr. G. Morant, induced him to have the superincumbent bog carefully dug away, and after some hours’ work the floor of a house became exposed to view; as the explorers approached its level, they were particularly careful to examine the layers next to it, in the hope of discovering some relics of its inhabitants; but, beyond ashes, nutshells (both in considerable quantities), some pieces of very rude pottery, and a few small worked flints, nothing was found. The floor, as may be seen by the accompanying engraving, is approached by a narrow causeway of black oak planks, similar to those of the floor itself, very rudely formed, of unequal size, and laid loosely, without any apparent fastening, except by occasional posts, as marked on the sketch. At the end of the causeway nearest to the floor are the remains of posts, which probably formed the entrance to the house, and at one side is a large tree stump of some soft wood resembling sallow. The timbers of both causeway and floor have evidently been fitted to the boll of the tree, proving that it must have existed before either the causeway or floor was laid. The latter sloped at a considerable angle to the south-west, owing to the withdrawal of the water from a small lake not far from the site of this ancient floor; the bog in former days was at least fourteen feet deep over it. In the memory of persons still living, this portion of Cargaghoge was entirely covered with water. About the centre of the floor was a collection of stone slabs, closely fitted together, with a substratum of blue clay, but all laid on planks of timber forming part of the floor. On this fireplace there was a quantity of ashes, and on the edge of the hearth a small corn-crusher of stone. Underneath the planks, as far as could be observed without disturbing them, a thick deposit of hazel and birch branches formed a foundation for the support of the flooring.

From the descriptions given in Irish MSS., it would appear as if the very earliest wooden dwellings were either rectangular or of oblong form, but there is absolute proof of the co-existence of circular houses, made chiefly or wholly of wicker-work. Similar dwellings of the Gauls are figured on Roman bas-reliefs; the plan of this kind of house resembled a tent; the poles were driven into the ground in a circle, the spaces between filled in with wicker-work, and the interstices made weather-tight by daubing them with clay. In the centre of the interior, a stout post, commensurate with the required height of the conical roof point, was firmly erected, and to this the rafters were attached, descending at a steep incline to the upright wall poles. According as they radiated from the central post their distance from each other correspondingly increased; in these spaces cross-beams were inserted, and across the radial rafters narrow slips of wood were fastened, forming a complete covering from the conical point of the roof to the eaves; a sheeting of rods was laid over this at right angles, and the framework of the roof was then thatched with straw, rushes, or sedge bound down with scollops.[59]

Gangways.—Some crannogs were connected with the shore by a wooden gangway supported on piles driven into the bed of the lake. The artificial island in the lake of Effernan, county Clare, affords a good example of this kind of passage. It has been often stated that the characteristic feature of Irish lake dwellings was their insularity, their complete disconnection with the land; yet it would be tedious to enumerate the many instances in which remains of both pile gangways and stone causeways have been discovered; although with regard to the latter it is quite possible that in some cases the so-called causeways may have been merely the stones that had been deposited around the base of the piles, to give solidity to the uprights supporting the footpath.[60] It has been suggested that these gangways, being under the water level, were meant to provide on sudden emergencies a means of secret access to the crannog, and that their oblique, sometimes even tortuous, course was for the purpose of preventing any but those accustomed to the submerged path from making use of it. Is it not more probable that the people who made it merely availed themselves either of a shoal or of the best foundation into which uprights might be driven? Wooden roads and causeways across the deep, treacherous morasses and soft miry banks with which lake dwellings were environed have been frequently discovered. A roadway, evidently made for convenience of the crannog in Loughnahinch, county Tipperary, was covered with a great accumulation of peat.[61] Another submerged roadway, constructed somewhat like an American corduroy road, was discovered in a bog between Castleconnell and the Esker of Goig, in county Limerick.[62] In the north portion of the Wexford estuary was a causeway that in ancient times connected Begerin to other islands; there were two rows of oak piles on which, apparently, had formerly been transverse beams.[63] In Duncan’s flow bog, Ballyalbanagh, county Antrim, was a wooden roadway laid on the surface of the black turf, level with stumps of deal corkers; this road was seven feet wide, formed of longitudinal oak beams sheeted with transverse planking of the same material. In the centre of the bog, where the foundation was soft (fig. 6), there were eight longitudinal beams, whilst in the firmer ground (fig. 7), near the edge of the bog, there were but three, one at each side and one in the centre. The roadway, with the exception of one log, was formed entirely of oak; holes worn in the oak planking had been mended (fig. 8) with pieces of deal fixed in position across the aperture. “On the roadway there are now five feet of uncut turf, while ten feet of ‘good turf’ are said to have been cut away. Over the good turf there must have been ‘white turf’ and clearing, which would add at least about five feet more to the thickness of peat over the cash,” or roadway.[64] A paved causeway, covered to the depth of eight or nine feet with bog, leads down to what used to be the edge of the water, at Kilnock crannog, county Antrim.[65] On an ancient wooden causeway or road in Ballykillen Bog, barony of Coolistown, King’s County, a remarkable axe, formed of bone (fig. 9), was found seven feet below the then surface of the bog; the axe is eight inches long, and the sharp cutting edge at the small extremity had been formed by an oblique cut of the bone. With it was a flint arrow-head (fig. 10) in a briar-root shaft, the thong which tied it still adhering.[66] Remains of cut reeds, ferns, heather, and sand or clay, are very frequently found strewn on the roads thus leading into crannogs.

Kitchen Middens and Refuse Heaps.—The most usual site of the kitchen midden, or collection of refuse thrown out of the dwelling, is at the entrance to the crannog, where was formerly the landing-stage or gangway leading to the shore; and what more natural than that prehistoric housekeepers should take the easiest method of getting rid of refuse by merely throwing it out of the door, a practice followed, on terra firma, by many of their descendants in Ireland at the present day. The accumulated mass of bones (invariably found in a broken state for extraction of the marrow) is in some instances immense; it is estimated that at Dunshaughlin, in Meath, about two hundred tons were sold for manure, three hundred tons were exhumed from the kitchen midden of one of the lake dwellings in Loughrea, county Galway, and fifty tons from that of Ardakillen, county Roscommon; the bones in the heaps have, evidently, in some instances, been gnawed by dogs after their owners had extracted the marrow, for which dainty the Irish appear to have had a peculiar relish, judging from their proverb, Ma bhris tu an cnamh char dhuighail tu an smior, i. e., though you have broken the bone, you have not sucked out the marrow: equivalent to saying, “you have done the most difficult part of the work, though you have not completed it.” Refuse heaps may be said to form also a perfect mine of antiquities, for every “cast” article of household gear was thrown into them; hence, the objects though numerous are generally fractured. After bones the next most frequent “find” consists of fragments of fictile ware. It has been remarked that if the former site of a crannog becomes again exposed to the light of day, by the gradual cutting away of the peat under which it lay buried, perhaps during centuries, then many objects calculated to excite the interest of archæologists might be turned up from time to time without attracting particular notice, and thus no means would be left to form even an approximate estimate of the date of the crannog; but if careful examination be made of a kitchen midden, exposed to view by the simple drainage of water from the site, then the antiquities discovered afford tolerably correct and safe data from which to calculate the age of the structure.

Canoes.—Some crannogs appear to have been veritable islands, the only means of communication with the land being by canoes; of these, in Irish and Scottish waters alike, remains have been frequently found near the dwelling, in some instances alongside the landing-stage, as if sunk at their moorings.[67] A canoe formed by hollowing out the trunk of a tree seems to have been almost universally the first attempt at boat-building, and to effect this, a people even in the rudest state of existence would possess sufficient ingenuity. Canoes are so universally found associated with crannogs, that their discovery in lakes and bogs in Ireland has been considered an indication of the existence of lacustrine dwellings in the immediate vicinity; but it may be safely concluded that, unless implements or articles of stone or bronze are found with “dug-outs,” they do not of themselves carry us back to prehistoric times, nor do they necessarily indicate the great antiquity commonly attributed to them. Canoes have been found of the oldest type known, and yet containing articles of iron of very modern form; therefore, it may be surmised that a people of primitive habits like the lake dwellers clung tenaciously to old customs, and their models remained unchanged during many ages. Irish single-piece canoes may be roughly divided into three classes or varieties—(1) the first, generally either sharp or rounded at both extremities, averages twenty feet in length, and about two in breadth, some however have been discovered square at both ends. Again, some are flat-bottomed and others round: the inside depth varies according to their state of preservation; (2) the second kind is generally of much greater length; one found, measuring forty feet, was round in the bow, but square in the stern, which was formed of a separate piece, let into a groove within a few inches of the extremity: this make is altogether more heavy and clumsy than the preceding; (3) the third variety is trough-shaped, and has been appropriately designated “the portable canoe”; the length is from eight to twelve feet; it is square at both ends, round in the bottom, and having projecting handles at either extremity, apparently for the convenience of carrying it from lake to lake. All alike seem to have been hollowed out of a single tree, probably in the fashion described by Captain Speke, in his Travels in Central Africa, wherein he says the negroes fell a large tree, lop off the branches, shape the timber, then cover its upper surface with wet mud, as it lies on the ground, and set fire to it, burning out the core, and finishing off with roughly-constructed hatchets the part unconsumed by fire.[68] In Lough Owel, county Westmeath, in the immediate neighbourhood of a crannog, a very large canoe was found in company with two of smaller size. The prow was in shape like a curved beak; it might be expected that the principle of the curve would have been carried out in its after end, but, whilst the entry is spoon-shaped, the stern is square, and a hollow but shallow groove cut at the very end was formerly filled by the stern board. This canoe was round in the bottom; twenty-four holes were drilled through the sides, and the same number through the floor. A canoe twenty feet nine inches long, four feet seven inches broad, and one foot eight inches deep, was found at Derryhollagh, county Antrim; another in the lake of Moynalty was twenty-four feet in length.[69] One unearthed at Ardakillen measured forty feet in length, by four feet across the bow,[70] whilst another in Drumaleague Lough, county Leitrim, was only eighteen feet long by twenty-two inches broad—not formed for speed, certainly—being square at stem and stern. A canoe at Cahore, in Wexford, was twenty-two feet in length, two-and-a-half feet across amidships, and eleven inches in depth (plate IV. fig. 1). At a place called Cornagall, about six miles from Cavan, was found one more than half consumed by the conflagration which had destroyed the crannog itself; in the bottom of this boat lay a complete set of tools, belonging to an ancient craftsman who had lived at a period subsequent to the adoption of iron tools.

In consequence of the low level of the Boyne in the summer of 1837, workmen engaged in taking gravel from the river, near the obelisk erected to commemorate the period

discovered a well-preserved “single tree” canoe, which was for many years after exhibited as a curiosity in Liverpool, but finally presented to the Royal Irish Academy. The length of this canoe is eighteen feet nine inches, it averages two feet ten inches in width, is twenty inches high in the side, and has three circular and artificial apertures in the bottom, as shown in the illustration[71] (plate IV. fig. 2.) Three canoes were found at Toome Bar; the one figured (plate IV. fig. 3), is hollowed out of a single piece of oak, the length, fifteen feet, with projecting beaks at prow and stern; it is twenty inches wide, fourteen inches deep, and is flat-bottomed; it lay “from six to eight feet below the surface, in a bed of sand and Lough Neagh clay.”

During the operation of changing a line of road about a mile and a-half from Enniskillen, the antique figured (plate IV. fig. 4), was exposed to view. Its position was almost equidistant from Lough Erne and Lough Rossole. Owing to the smallness of its proportions as regards beam, objections have been raised to its claim to be classed as a canoe, and it has been suggested that it was perhaps a brewing vat for manufacture of some kind of drink. Impossible to say what the original length of this square and hollowed block of oak may have been, but the remaining portion measures about fifteen feet: the sides and bottom are thin, the depth is one foot, the breadth at its remaining end only one foot three inches; that end, however, is seven inches thick, and from it, on the exterior, two handles cut out of the solid block project, as shown in the drawing.[72] The great difference between the thickness of the sides and end may be accounted for by the presence of the handles, as they would need to be attached to solid timber if required for use as lifting agents; the diameter of these handles is about three inches, the length six inches, and at the end, between the handles, there is a hole by which this antique could be drained. If it be really a canoe, the handles would prove most serviceable for the purpose of transportation from one lake to another, and for the chase of wild fowl on lake or river, would meet the requirements of the primitive sportsman. A groove cut upon the interior of what may be termed the remaining portion of the gunwale, seems as if intended for reception of a covering in the style of an Esquimaux canoe, and, owing to the extreme narrowness of the supposed craft, this arrangement would be absolutely necessary for the safety of the occupant.[73] A portable single-piece oaken canoe or trough of similar description, twelve feet in length, by three in breadth, and furnished with handles, was found in the bog of Ardagh, parish of Maghe-Ross, and is figured in Shirley’s Dominion of Farney.

The foregoing furnish specimens of the three classes into which canoes may be divided; in all, about fifty have been found in Ireland.[74] Owing to the preservative properties of peaty matter, the wood of some of these canoes was in a fairly sound state when dug up: one of the largest and most perfect found in connexion with the Strokestown crannogs, was cut up by a “grim utilitarian” for roofing material, and the best canoe belonging to the Ballinderry crannog was split into firewood.

Paddles.—For the purpose of propelling a canoe paddles were essential, and of these numbers have been discovered: there are several in the Museum of the Royal Historical and Archæological Association at Kilkenny, as also in the Museum of the Royal Irish Academy, Dublin. The paddle, two feet seven inches long, by five and a-half inches across the blade, as represented (in plate IV. fig. 5), was found in the immediate neighbourhood of a crannog site at Toome Bar, on the Lower Bann. It is the largest of two from the same locality; both are imperfect, the handle of each being fractured in the same spot, so that the original length cannot be ascertained; but as they were not more than half an inch thick, they could only have been employed in propelling a very light craft, perhaps a portable canoe.[75]

Anchors.—For the purpose of holding a canoe stationary an anchor is requisite, but of these not more than three have as yet been discovered. The one figured (plate IV. fig. 6) is of stone. The shank must have been of wood, lashed to the stone. There was with the canoe discovered in the Boyne what bore the appearance of a kind of wooden anchor. At Toome Bar was found an anchor or grappling instrument twenty-one inches long, but being formed of iron it should be viewed as comparatively modern (plate IV. fig. 7).

Curach.—There is yet another kind of boat, the curach, that must have been employed by these lake dwellers; of it, however, on account of the perishable materials of which it was composed, no remains have as yet been exhumed. We may all recollect, when reading English history in our childhood, the description given of the primitive Celtic boat, constructed of basket-work and covered with skins, in which the Picts and Scots are said to have invaded Britain in crowds, and of which the Britons themselves made use: this is frequently referred to by old classical writers. Herodotus mentions boats of this kind as existent in his time on the Tigris and Euphrates; similar skiffs are used on those rivers at the present day; boats of analogous construction are employed in some parts of India; they are propelled by paddles where the water is deep, and poled over the shallows. Nothing can be more simple than the construction of these skiffs; only two materials are requisite, and they the most accessible in the country, i.e. bamboo and hides. When Cæsar had constructed boats in Spain, after the manner learnt by him in Britain, it is said that “the keels and ribs were made of light timber, the rest of the hull being woven together with basket-work, and covered with hides.”[76]

Pliny says:—“Even now, in the British channel, they (the boats) are made of osiers, covered with hides sewn together.” Solinus, describing the rough sea between Britain and Ireland, says that the natives “sail in ships made of osiers, which they surround with a covering of hides.” Adamnan, in his life of St. Columba, refers to a voyage made in a curach by St. Cormac. The curach is said to be still in use on the Severn,[77] and on some parts of the coast of Ireland, in shape and build similar to those of thousands of years ago; at the same time it may be affirmed that few persons of the present generation could declare they have seen the true curach, that term having been now transferred to boats covered with coarse tarred canvas, and which differ widely both in form and method of construction from their ancient prototype. The curach seen by W. F. Wakeman in use on the river Boyne so late as the year 1848 is thus described by him:—A regular frame of willow ribs, generally laid in pairs, and extending along the sides and floor, formed the skeleton of the future boat, which was in the form of the bowl of a spoon, a little broader towards one end than the other; about eight feet in length, but very nearly circular. The extremities of the ribs for a depth of about eighteen inches from what would now be called the gunwale, were set in a very thick, strong, and closely-woven band of wicker-work, above which the ends of the rods slightly projected. Midships was a thwart of ash or oak pierced with four holes, two near either end, through which were rove thongs, composed of twisted osiers connecting the seat, or thwart, with various portions of the above mentioned band, so as to bind the work together. The frame was then covered over on the outside with skin, untanned, of the horse or cow; and the result was the completion of a boat well adapted for the requirements of fishermen.[78] The raw hide of a newly slain animal, properly extended presented a ready means of constructing a boat, and became to the early inhabitants of the British Islands what the birch-tree bark is to the American Indian. In the sculptures from Nineveh a similar use of the hide is observed, as a means of crossing rivers, but the application is less ingenious, being merely a skin inflated with air like what is called on some parts of the Irish coast a “stookey,” and with which, not unfrequently, fishermen, so late as the year 1860, floated their nets and lines; the skin of a dog or any other animal served the purpose.[79]

Ingenuity of Lake Dwellers, Clothing, &c.—It has been remarked that the brains of most savages and the skulls of most primitive races are larger than, in theory, they ought to be; often rather larger than the brains and skulls of the average masses of the great cities of the present day; but this need not cause surprise, if the life of intelligent interest passed by the savage child be taken into consideration. From the tenderest age he was observant of all the devices practised by his parents for procuring clothing, food, means of defence, in short, all the essentials of existence; the natural result of his wild life was health and strength; indeed, on the principle of the survival of the fittest, it could only be the robust who lived through the hardships and climatic exposure incidental to a savage life. The lake dweller was no exception to this rule, for his ingenuity would be most fully exercised in endeavouring to procure the means of sustenance for his family. It is easy to imagine the various daily occupations needful in his struggles for existence. Timber from the forest supplied him with materials both for his dwelling and for fuel; the skins of wild animals furnished him with clothing, he shaped them with a sharp flint flake, and sewed them with thongs, using as needle the pierced bone of some bird or small mammal. In early Irish history mention occurs of skin or leather garments: when Muircheartach MacNeill made his celebrated circuit of Ireland, A.D. 942, it is stated that his soldiers were clad in long leather cloaks. We are not left to mere conjecture regarding the manner in which the men of these primitive times protected themselves from the inclemency of the weather. In the year 1821 the body of a man, about six feet in height, with dark, reddish-coloured hair, short beard, and teeth in a good state of preservation, was found ten feet below the surface of a bog, on the lands of Gallagh, near Castle Blakeney, county Galway. The head, legs, and feet were bare, but the body was covered with a deer-skin tunic reaching to the knees and half-way down the arms; in front it was laced and fastened by thongs of the same material. The mantle was, unfortunately, much injured in the disinterment, but a few fragments of it still hung together; portions of the seams sewed with fine gut of three strands still remained; “the regularity and closeness of the stitches are most remarkable, as shown by the accompanying cut, in which a portion of one of the joinings is represented double the natural size. This closure was effected by what is termed the looped stitch, similar to that used in working a button-hole, so that by having each stitch knotted the chance of ripping was lessened.”[80] The age of the Irish mummy (if we may apply that term to the body here described) is considered by some to date back at least 2000 years.

A bed of growing peat is endowed with marvellous powers. It seems to act like the ancient Egyptian process of embalming on the bodies of men or animals that have become accidentally entombed in it, preserving them for centuries after their contemporaries have, by the ordinary laws of nature, totally disappeared, and organic substances, such as butter, seem also to feel its influence. Peat may bear comparison with ice, the well-known preservative properties of which were strikingly illustrated by the discovery on the shores of Lake Oncoul, in Siberia, of a carcass of the Elephas primigenius, or mammoth (supposed to have become extinct in the Pleistocene period) in a perfect state, and so well refrigerated that, when thawed, the dogs of the neighbourhood devoured its flesh. Again, in 1846, the summer in Siberia had been unusually hot; the frozen marshes which extend along each side of the river Indigirka were thawed, and a perfectly preserved carcass of a mammoth floated down the stream. This monster had most probably met his death centuries before by sinking into the deep snow of the morasses, was frozen over, and thus remained until the exceptional summer heat melted his icy prison.

Stone, Bronze, and Iron Ages.—We know that the learned have divided the period man has inhabited the globe into what may roughly be called three Ages—the Stone, the Bronze, and the Iron. Ancient mythology presented us with another, ycleped the Golden, when our planet was supposed to be a paradise, and man lived in a state of perpetual happiness; it is to be feared that the idea of a golden age, either past or to come, is purely mythical. Future archæologists may, perhaps, be tempted to apply the designation “Steel” to the present or now commencing epoch, in order to distinguish it from the mere “Iron Age.” Improved methods of manufacture are now-a-days causing steel in some degree to supersede its parent metal, iron, even as iron superseded bronze. Excavations on the site of crannogs have demonstrated clearly the fact that some of them have had a continuous existence throughout the three ages of Stone, Bronze, and Iron. Classification of the earth’s history into those three ages does not, however, imply a defined and distinctive period when stone, bronze, or iron alone was in exclusive use, though there may possibly have been a time in which only stone and bone were available. When the empires of the Tigris and Nile were in their prime, the northern littoral of Europe was inhabited by a race using implements of bone and stone, but these regions were in the Bronze Age[81] at the period when the Phœnicians had attained the zenith of their power. According to some writers, the inhabitants of the Baltic littoral had not till early in the Christian era discarded bronze and stone for iron. Although weapons of bone or flint were certainly of an earlier age than bronze and iron, yet it is more than probable that flint, bronze, and iron may have been in use at one and the same period, and even in the same locality, down to a period long subsequent to the Christian era. To this day the Esquimaux use bone implements, but they also employ iron, so that in remote countries a stone age might be said still to exist, the few iron implements in possession of the wild tribes being acquired by recent contact with western civilization. In Ireland there is no fixed line of demarcation between the stone, the bronze, and the iron age; there was an overlapping and co-mingling as the better and more useful metal gradually superseded its predecessor. Thus a stone instrument, by itself, would be a most deceptive guide in determining the state of civilization of the inhabitants of the site on which it was discovered, because stone implements are also found associated with articles both of bronze and iron. “Like the three principal colours of the rainbow,” writes Mr. Evans, “these three stages of civilization overlap, intermingle, and shade off, the one into the other; and yet their succession, as far as Western Europe is concerned, appears to be equally well defined with that of the prismatic colours, though the proportions of the spectrum may vary in different countries.” Petrie, the well-known Irish antiquary, was the first to claim for a large class of iron remains the position of an interesting connecting link, which they are now allowed to hold, between the bronze manufacture of a remote age and the industrial achievements of comparatively modern days. At the period of the first discovery of the remains of Irish lake dwellings, archæologists looked upon objects of iron found in lakes, or in their immediate vicinity, with very little interest, for it was considered that they could not have held out against the corroding influence of water for a lengthened period; therefore iron was supposed to stamp lacustrine habitations with a mediæval or even modern impress. The belief was then very general that the inhabitants of Erin of the prehistoric period, having existed generation after generation as manufacturers of flint and stone weapons, had gradually, through some unknown channel, become acquainted with gold, silver, and bronze, and that this latter metal, down even to the advent of St. Patrick, was used almost exclusively in the manufacture of weapons of war, small ornaments for personal adornment, and objects of domestic use. Articles of stone, bone, wood, bronze, and iron have been discovered in strange medley: swords, spear and javelin heads, axes, daggers, knives, hones, querns, shears, tweezers, chains, combs, pins, brooches, beads, horse trappings, cauldrons of hammered bronze, lumps of iron slag, &c.—in short, every conceivable object, from the rudest flint implement to highly-finished silver ornaments.

The accidental discovery of the great historical crannog of Lagore, in the county Meath, already referred to, presents the first, and probably the most important, treasure-trove of earliest iron implements. In A.D. 848 an Irish chief, with his Danish allies, plundered this island fortress and burnt it; whilst in 933, nearly a century later, the place again suffered a similar fate at the hands of another marauder. Nothing more was heard of it till the date of its disinterment, about the year 1840. The latest period, therefore, to which the majority of the antiquities so plentifully found within and around this stronghold may be referred, is somewhere between the eleventh and earliest half of the tenth century. This approximate date is about the historic limit in which the so-called “Iron Age” may be allowed to have reached back in Ireland. How long it had previously existed there must be matter of conjecture; but it is almost incredible that its natives should have been far behind their neighbours in the art of metallurgy; and we know that Cæsar[82] found the Britons acquainted with the use of iron. It can only be surmised that, at some very remote period, bronze as the prevailing material gave way to iron, but the period of transition may probably be counted by centuries.[83]

Weapons and Tools.—In nearly all Irish crannogs, more especially in the larger sites, weapons of war and of the chase have been discovered in abundance, consisting chiefly of arrow- and spear-heads, swords, daggers or skeans, knives, and axe-heads. The numerous fragments of artificially fashioned bone found in and around crannogs plainly demonstrate how much that material was utilized by their inhabitants; many tips of the antlers of deer contained in the collection of the Royal Irish Academy and in that of the Royal Historical and Archæological Association, have evidently been sawn from the original branches, and employed in forming handles for swords, knives and daggers; some are ornamented, whilst others are pierced with a hole at one extremity, having evidently been fabricated for a distinct purpose, for spear- or javelin-heads, &c.; these were attached to handles or shafts, by means of the sinews of animals, or thongs of skin. Amongst primitive races the transition from tool to weapon is slight; the same article must, in many cases, have served the double purpose. Arrow- or spear-heads have been found of bone, horn, flint, bronze, and iron; they are usually of small size. Figs. 12 and 13, from Lough Ravel, county Antrim, represent (half-size) flakes fashioned into arrow- or spear-heads. Fig. 14 is a flake of basalt (full-size) from Toombridge, in the same county. Fig. 15 is a flint implement from the recently discovered crannog of Lisnacroghera.[84]
