The _Deerpark Monument._--The interesting megalithic monument in the Deerpark, Hazlewood demesne, four miles east of Sligo, differs from any other known monument in the British Isles. It is known as Leacht Con Mie Ruis, the ‘Stone of Con the son of Rush,’ and more than one visionary archæologist has styled it the ‘Irish Stonehenge.’ The structure consists primarily of an oblong, or blunted oval, figure, formed of rude, undressed stones, generally of considerable length and thickness, and averaging but 2 or 3 feet in height. This central area extends, as nearly as possible, east and west. Its extreme length is 50 feet 6 inches; its greatest diameter 28 feet. From the western end extends an oblong compartment, constructed of stones similar to those forming the oval, measuring 27 feet in length by 12 feet 6 inches in breadth. The entrance to this extension is by a kind of portal, the sides of which consist of two rude, unhewn stones, about 3 feet in height. These are surmounted by a horizontal lintel, about 8 feet long, and 2 feet 6 inches in thickness, forming a low but perfect trilithon. Fergusson, in his _Rude Stone Monuments_, very incorrectly states that these stones, like those forming two other similar entrances, have been ‘squared and partially dressed.’ The western apartment is divided by two projecting stones, which may have been capped with a lintel. The space between them is barely sufficient to allow the passage of a moderately-sized man. This end of the monument is composed of two stones of great size, the outermost leaning against its neighbour. They are about 7 feet in length, 2 feet in thickness, and over 6 feet in height. Immediately adjoining, and touching them, to the westward, are the remains of a stone circle, about 20 feet in diameter, the area of which was probably occupied by a low cairn or mound. The spot, however, has been so tossed about that little of its original character remains. The same remark applies to the state of a similar circle found at the eastern termination of the monument. At the eastern extremity of the central enclosure are two projections, precisely similar in style to that at the opposite end. They are entered by trilithon openings, the height from ground to lintel measuring about 3 feet, and the height to the upper surface 5 feet. These prolongations, which have been absurdly styled ‘aisles,’ run parallel to each other, one measuring 27 feet in length, while its companion, that to the south, is 3 feet shorter. Both are divided into two compartments, of unequal size, by projecting stones. There is a space between them, 5 feet 6
