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.
