that the three kings, Amlaff, Imar, and Ainsle, were plundering the territory of Flann, the son of Coaing.’ It is an interesting fact that the knives are similar in every respect to a number discovered, together with a quantity of other objects, in the bog of Lagore, near Dunshaughlin, and which there is reason to refer to a period between the ninth and the beginning of the eleventh centuries. Upon the chamber being cleared out, a passage 27 feet in length was discovered, the sides of which incline considerably, leading in a westerly direction towards the side of the mound, and composed, like the similar passage at Newgrange, of enormous stones placed edgeways, and covered in with large flags. The chamber, though of inferior size to that of Newgrange, is constructed so nearly upon the same plan, that a description of the one might almost serve for that of the other. It is 9 feet by 7 feet and 11 feet high. There are three recesses between 5 and 6 feet deep; these, however, do not contain basins. The south recess leads into a double set of chambers, one extending south and the other west. A single stone 8 feet long forms the floor of the south passage, in the centre of which is a shallow oval ‘apparently rubbed down with some rude tool.’ A huge stone, in height 9 feet, in breadth 8 feet, placed between the north and east recesses, is remarkable for the singular character of its carving. A portion of the work upon this stone bears a resemblance to Ogam writing. [Illustration: Carving on a Stone at Dowth.] [Illustration: Carving on a Stone at Dowth.] Another sepulchral chamber, of a quadrangular form, portions of which show a great variety of carving, among which the cross, a symbol which neither in the old nor the new world can be considered as peculiar to Christianity, is conspicuous, has been discovered upon the southern side of the mound. Here, as elsewhere, during the course of excavation, the workmen unearthed vast quantities of bones, half-burned, many of which proved to be human; ‘several unburned bones of horses, pigs, deer, and birds, portions of the heads of the short-horned variety of the ox, and the head of a fox.’ They also found a star-shaped amulet of stone, a ring of jet, several beads, and some bones fashioned like pins. Among the stones of the upper portion of the cairn were discovered a number of globular balls of stone, the size of small eggs, which Sir W. Wilde supposed probably to have been sling stones. Further excavations under the direction of the Board of Works (1885) led to other discoveries. An opening was made on the north side of the known entrance that ‘led to a passage which terminated at either end by circular cells carefully roofed with corbelling stones’; and, where it met the entrance to the originally known chamber, a flight of steps was discovered. This and the character of the work, which is microlithic, indicate the portion of the underground passages and chambers to be a much later addition.
