"The third and lowest hearth, or rather fire-place, for no large stones appeared, lay about eighteen inches lower than that last described, and nearly beneath it. In connection with both, and mingled generally in the soil--above, below, and for a considerable distance around--were broken animal remains; innumerable teeth of swine, deer, etc., boar-tusks; charcoal; 'burnt stones;' a bead of jet; a bronze harp peg; an animal's head in iron, probably the leg of a pot; an article of iron resembling a small, narrow, double axe-head or pick; rude, oval-shaped hammer-stones; a well-formed knife of trap; an admirably-worked 'thumbflint;' a core of flint from which flakes had been struck; portion of a whetstone, and, finally, fragments of the sides and bottoms of fictile vessels, together with ears or handles of the same ware." (B. 441, p. 372.) COAL-BOG, NEAR BOHO. Mr. Plunket, who examined the remarkable find which was brought to light here in 1880, thus describes the wooden structures met with:-- "After a minute inspection, I perceived that we were standing on what was once an artificial island, oval in shape, slightly elevated in the centre, and dipping with a gentle slope on all sides, the outlines of which can still be easily traced. It is 60 yards long, and 14 yards across at its greatest width. Piles, or stakes, with rudely-sharpened ends and varying in size, are found at intervals all over this area, and rough oak planks, about the size of railway sleepers, may be seen lying in rows here and there, and generally resting on a layer of branches, the whole being covered over with a stratum of clay and stones, mingled with charcoal and ashes. It is quite manifest that this is the site of an ancient crannog, or artificial island. The surrounding depression, now filled with peat, known as the Coal-Bog, and covering some scores of acres, once formed a large sheet of water." (B. 345, p. 66.) Here perforated posts and frameworks of what were supposed to have been wooden huts were found. In one place a wooden structure measuring 11 feet 10 inches by 6 feet 3 inches, formed of rude wooden beams, with roughly-executed mortises, was found no less than 21 feet below the surface of the peat. Two flint implements, several fragments of hand-made pottery, devoid of ornamentation, broken hazel-nut shells, and in the vicinity, at the same depth in the peat, a few wooden dishes. The stool of a huge _pine tree_, which, "before its decay, must have measured 14 feet in diameter," was found 2 feet above the level of the floor of the hut, which sent its roots downwards. Subsequently Mr. Wakeman states that near this crannog lumps of "bog butter," rolled up in cow-hides, were found, and that the wood of the huge root of the tree above referred to turned out on analysis to be _yew_, and not pine.[74] LISNACROGHERA.
