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.
