"About a mile to the east of the village of Dunshaughlin, on the townland of _Lagore_, and near the margin of a 'cutaway' black bog, is a circular mound, slightly raised above the surrounding plain, its highest central part being about eight feet above the margin, and the circumference of the mound measuring 520 feet. A small stream passes through the circle; and the whole bog in which it is situated occupies a slight concavity of about a mile and a half in circumference, bounded by raised tillage and pasture lands. Within the memory of some of the old inhabitants of the neighbourhood, this bog was covered with water during the greater part of the year, and it is so invariably during winter up to the present period. A large pond is still in existence in one of the fields adjoining the mound. A few years ago some labourers, while clearing the stream-way, discovered several bones protruding from its sides; and in May, 1839, the quantity of bones found in the drain was so great, and their value so well known, that a further examination was made, when it was discovered that the greater part of the mound was composed of the remains of animals, placed there in the following manner:-- "The circumference of the circle was formed by upright posts of black oak, measuring from 6 to 8 feet in height; these were mortised into beams of a similar material, laid flat upon the marl and sand beneath the bog, and nearly 16 feet below the present surface. The upright posts were held together by connecting cross-beams, and fastened by large iron nails; parts of a second upper tier of posts were likewise found, resting on the lower ones. The space thus enclosed was divided into separate compartments, by septa or divisions that intersected one another in different directions; these were also formed of oaken beams in a state of great preservation, but joined together with greater accuracy than the former, and in some cases having their sides grooved or rabbited to admit large panels driven down between them. The interiors of the chambers so formed were filled with bones and black moory earth, and the heap of bones was raised up in some places within a foot of the surface. It was generally found that the remains of each species of animal were placed in separate divisions, with but little intermixture with any other; and the antiquities, etc., were found along with them, without any order or regularity, but for the most part near the bottom."
